# Hospodality — Coffee, tea and the café Source: https://www.hospodality.com · hello@hospodality.com ## Coffee, tea and the café (177) ### Origins #### Ethiopian coffee Ethiopia is where Coffea arabica grows wild, and that genetic depth is why Ethiopian lots taste the way they do. Most of the crop comes from smallholders with a handful of trees each, delivering cherry to washing stations that blend it by area, so a lot is named for a region, a woreda or a station rather than one farm. The trade still talks about Yirgacheffe, Guji, Sidama, Limu and Harrar as shorthand: washed Yirgacheffe for jasmine, bergamot and lemon tea; naturals from Guji or Sidama for blueberry and strawberry jam; Harrar for wilder, winey dried-fruit naturals. Varieties are usually listed as ‘heirloom’ or ‘landrace’ because thousands of local types grow mixed together, though research centres have released numbered selections such as 74110 and 74112 that now appear on bags. In a café, Ethiopian coffee is the easiest way to show a guest that coffee can taste of fruit and flowers. It shines as filter and as a lighter espresso, but bright washed lots can turn sharp in milk, so many shops keep a chocolatey house blend for flat whites and rotate Ethiopia as the guest filter. Grading and export rules have changed several times over the past two decades, which affects how traceable a lot can be, so ask your roaster what the label actually means. - Arabica originated in the Ethiopian highlands - Most Ethiopian coffee comes from smallholders via washing stations - ‘Heirloom’ means mixed local varieties, not one cultivar - Washed lots lean floral; naturals lean berry - Bright Ethiopians can taste sour in milk drinks #### Kenyan coffee Kenyan coffee is famous for intensity: blackcurrant, tomato-leaf savouriness, grapefruit and a juicy acidity that holds up even at darker roasts. Much of it is grown by smallholders organised into cooperative societies that run factories (the Kenyan word for a wet mill), where cherry is pulped, fermented, often soaked and washed, then dried on raised beds. Lots are graded by bean size, so you will see AA (largest), AB, PB (peaberry) and C on lists; size says nothing guaranteed about cup quality, but AA and AB from good factories command premiums. SL28 and SL34 are the classic varieties behind the flavour, with Ruiru 11 and Batian bred for disease resistance. Kenya historically sold through a central auction in Nairobi, with direct sales also allowed for licensed marketers, and the rules have been reformed repeatedly, so traceability depends on who your importer works with. On a café bar, Kenyan filter is the coffee that converts tea drinkers who like something sharp and juicy. As espresso it can be thrilling but punishing: underextract it slightly and it is sour enough to make guests wince. Pull it a touch longer and warmer than your blend, and warn staff not to recommend it to someone who orders a ‘strong, not bitter’ latte. - Kenyan wet mills are called factories - AA, AB and PB are size grades, not flavour grades - SL28 and SL34 drive the classic blackcurrant profile - Kenyan lots are often soaked after fermentation - Best showcased as filter or a longer espresso #### Colombian coffee Colombia is a backbone origin for UK cafés because it produces arabica almost all year somewhere in the country. Its mountain ranges create staggered harvests: a main crop and a smaller ‘mitaca’ fly crop in many regions, so fresh Colombian green arrives across the year, which helps roasters keep blends consistent. Huila, Nariño, Cauca, Tolima and Antioquia are names you will see; southern regions such as Nariño grow at high altitude near the equator and are known for bright, sweet cups. Most farms are small, and the national coffee federation runs buying points, research and the Castillo variety, bred for resistance to leaf rust; Caturra, Colombia (the variety) and increasingly exotic types like Pink Bourbon and Gesha also appear. Colombia is a hotbed of experimental processing, with extended fermentations, co-ferments with fruit, and ‘thermal shock’ lots that taste of tropical sweets. Those are polarising; a regular who loves your caramel house espresso might find a co-fermented lychee Colombian tastes artificial. For everyday service, a washed Colombian gives you balanced caramel, red apple and cocoa that works with milk and black. When explaining it to a guest, ‘sweet, round and easy’ is honest; save the fruit talk for the experimental lots and say plainly when flavour comes from process. - Colombia harvests in staggered crops across regions - The mitaca is a smaller secondary harvest - Castillo was bred for leaf-rust resistance - Co-fermented lots can taste of added fruit by design - Washed Colombian is a reliable all-rounder for milk #### Brazilian coffee Brazil is the world’s largest coffee producer by a wide margin, and its beans sit inside a huge share of UK espresso blends. Much of it is grown on large, flat or gently rolling estates in Minas Gerais, São Paulo and Bahia, at lower altitudes than Central American or East African farms, and harvesting is often mechanised. Natural and pulped-natural processing dominate, giving low acidity, heavy body and flavours of milk chocolate, roasted nuts and caramel. That profile is exactly what a flat white needs: it cuts through milk without sourness, and it forgives a grinder that drifts. Roasters buy Brazil as a base, then add a washed Central American or a fruity Ethiopian for lift. Speciality Brazilian microlots exist and can be lovely, with yellow-fruit sweetness from the Cerrado or Mantiqueira de Minas, but the country’s reputation is volume and value. Frost and drought in Brazil move the global commodity price, which feeds through to your green and roasted coffee costs months later; when trade press reports a Brazilian frost, expect roasters to revise price lists. Brazil also grows a lot of robusta, locally called conilon, mostly in Espírito Santo and Rondônia. For staff training, Brazil is the ‘chocolate and nuts’ benchmark against which brighter origins are compared. - Brazil is the largest coffee producer in the world - Natural and pulped-natural processing dominate - Typical profile: low acidity, nutty, chocolatey - Brazilian weather events move global coffee prices - Robusta in Brazil is called conilon #### Central American coffees Guatemala, Honduras, El Salvador, Costa Rica, Nicaragua and Panama give UK roasters clean, sweet washed coffees that slot into blends or stand alone. Guatemala’s Antigua and Huehuetenango are known for cocoa, brown sugar and gentle citrus; Huehuetenango’s high, dry valleys produce some of the brightest lots. Honduras is the region’s largest producer, with quality transformed over the past twenty years; Santa Bárbara and Marcala names show up on good menus. El Salvador kept a lot of old Bourbon and Pacas trees, giving soft, sugary cups. Costa Rica has a ‘micro-mill’ culture where farmers process their own cherry, leading to the honey-process vocabulary of yellow, red and black honeys. Panama is known for Gesha, which sells for extraordinary prices at auction and is usually offered in cafés as a premium filter at a separate price. Harvests run roughly from late in the year into spring, so new-crop Central Americans tend to land in the UK in summer and autumn. Behind the bar, these coffees are dependable: they dial in predictably, taste good in milk and black, and give staff a clean reference for ‘sweetness’ and ‘balance’. When a single origin rotates, a Central American is the safe pick for a shop whose regulars mostly drink lattes. - Honduras is Central America’s largest coffee producer - Costa Rica popularised the honey-process terms - Panama Gesha is usually sold as a premium filter - New-crop Central Americans typically land in the UK mid-year - Washed Central Americans dial in predictably #### Asian and Pacific coffees Indonesia, India, Papua New Guinea, Yunnan in China, Vietnam, Myanmar and Thailand all export coffee, and each fills a niche on a UK menu. Sumatra is famous for wet-hulling (giling basah), where parchment is removed while the bean is still damp, producing earthy, herbal, cedar-and-tobacco cups with heavy body and low acidity, plus a distinctive dark-green bean. Sulawesi, Java and Bali offer cleaner variations. India grows both arabica and robusta, and its ‘monsooned Malabar’ is exposed to humid monsoon winds in open warehouses until the beans swell and pale, giving a low-acid, musty, spicy cup popular in traditional espresso blends. Papua New Guinea’s smallholder coffees can be bright and fruity. Vietnam is the second-biggest producer overall and overwhelmingly robusta, the base of phin-filter coffee with condensed milk. Yunnan has grown rapidly and now sends washed and natural lots that would have surprised buyers a decade ago. In practice, Asian coffees are used to add body and depth to blends, or sold as a talking point. Earthy Sumatran is divisive: some guests call it ‘proper strong coffee’, others say it tastes like a damp forest. Describe it honestly as savoury and heavy, and offer a taster before selling a bag. - Wet-hulling gives Sumatran coffee its earthy character - Monsooned Malabar is deliberately exposed to humid air - Vietnam is the world’s biggest robusta producer - Yunnan is a fast-growing source of speciality lots - Asian coffees often add body to blends #### Robusta in the café Robusta is the common name for Coffea canephora, a hardier species that grows at lower altitudes, resists some diseases better and yields more than arabica. It typically carries roughly double the caffeine of arabica and less sugar and lipid, which shows as a harsher, rubbery or woody bitterness and a thick, long-lasting crema. That crema is why traditional Italian blends often include a portion of robusta, and why it is the backbone of instant coffee and much supermarket coffee. In UK speciality cafés robusta was long dismissed, but ‘fine robusta’ from carefully picked and processed lots is gaining interest, partly because climate change pressures arabica and robusta tolerates heat better. If you use a blend containing robusta, train staff to say so, because guests sensitive to caffeine deserve to know a double shot may hit harder than expected. It behaves differently on the machine: crema can mask underextraction, so taste rather than judge by colour. A small percentage of good robusta can give milk drinks a punchy, chocolate-and-cereal backbone that cuts through large lattes and oat milk. Cost is lower on the commodity market, though fine robusta is priced closer to good arabica. Never call it ‘stronger coffee’ without explaining you mean caffeine, not just flavour. - Robusta is Coffea canephora - Typically about twice the caffeine of arabica - Produces thick, persistent crema - Common in Italian espresso blends and instant coffee - Fine robusta is a growing speciality category #### Coffee varieties explained Varieties (strictly ‘cultivars’ for bred types) are to coffee what grape varieties are to wine, though origin and process often matter more to the cup. Typica and Bourbon are the two historic arabica lines that spread from Yemen; most traditional varieties descend from them. Caturra is a dwarf mutation of Bourbon, Catuai a cross of Mundo Novo and Caturra, and Pacas a dwarf Bourbon from El Salvador. Catimor and Sarchimor families, and descendants like Castillo, carry genes from the Timor Hybrid, a natural arabica-robusta cross, which brings leaf-rust resistance; older buyers sometimes claimed these taste flatter, but good farming makes them taste fine. Gesha (also spelled Geisha) is the celebrity, with jasmine and bergamot aromatics and high prices. SL28 and SL34 are Kenyan selections; Pink Bourbon, Sidra and Wush Wush are fashionable on menus. F1 hybrids are newer crosses bred for yield and resilience. In service, varieties are useful as a story, but don’t over-promise: a guest who loved ‘a Gesha’ elsewhere may not love yours if it is roasted differently. The honest rule for staff is to describe what is in the cup today, use the variety as a supporting detail, and know two or three basics so they can answer ‘what’s Bourbon?’ without confusing it with whisky. - Typica and Bourbon are the two historic arabica lines - Caturra is a natural dwarf mutation of Bourbon - Timor Hybrid genetics give rust resistance - Gesha and Geisha are the same variety - Origin and process often matter more than variety #### Altitude and terroir Altitude is shorthand on coffee bags for something real: higher farms near the equator are cooler, so cherries ripen more slowly, building denser beans with more sugars and acids. That generally means brighter, more complex cups, though latitude complicates it; a farm at 1,200 metres in southern Brazil can be as cool as one far higher in Colombia. Soil (volcanic soils in Central America and parts of East Africa), rainfall pattern, shade cover and how dry the harvest season is all shape the coffee and how it can be processed. Density matters to roasters, because hard, dense beans take heat differently from soft, low-grown beans and need a different roast profile. For a café, the practical takeaway is that ‘strictly hard bean’ or ‘SHB’ on a Central American bag is an altitude grade, while ‘1,800 to 2,100 masl’ just means metres above sea level. Use altitude as a quality signal, not a guarantee. When explaining to guests, a simple line works: ‘grown high up, so it ripens slowly and tastes brighter and sweeter.’ Don’t use altitude to justify price on its own; a badly picked high-grown lot will still taste worse than a well-processed lower one. Terroir talk is credible only when the roaster can name the farm or station. - Higher altitude slows ripening and increases density - Latitude changes what altitude means - SHB means strictly hard bean, an altitude grade - masl stands for metres above sea level - Dense beans need different roast profiles #### Coffee and climate change Coffee is highly sensitive to temperature and rainfall, and climate change is already reshaping where and how it can be grown. Arabica prefers cool, stable conditions; rising temperatures push suitable land uphill, and many studies project significant losses of current arabica-growing areas by mid-century, though exact figures vary by model. Heat and erratic rain also encourage diseases and pests such as coffee leaf rust and coffee berry borer. Responses include planting rust-resistant and heat-tolerant varieties, agroforestry and shade-growing, irrigation, moving farms higher, and exploring other species such as robusta, liberica and wild species like Coffea stenophylla, which tastes arabica-like but tolerates more heat. Weather shocks in major origins, such as droughts and frosts in Brazil or drought in Vietnam, drive price spikes felt in UK cafés. For café owners, this is mostly about context and communication: guests increasingly ask about sustainability, and price rises have a real story behind them. Be careful not to overclaim: ‘carbon neutral coffee’ usually relies on offsets and should be explained accurately. Practical actions in a café, such as cutting waste milk, offering reusable cups and choosing roasters who invest at origin, are easier to back up than headline claims. - Rising heat pushes arabica-growing land uphill - Leaf rust and berry borer spread more in hotter conditions - Coffea stenophylla is studied for heat tolerance - Weather shocks in Brazil and Vietnam move prices - ‘Carbon neutral’ claims usually rely on offsets #### Liberica and other coffee species Arabica and robusta dominate trade, but there are well over a hundred coffee species. Liberica (Coffea liberica) grows into large trees with big, irregular beans and is grown mainly in parts of Southeast Asia, especially the Philippines and Malaysia, where it is sold as ‘barako’ in some regions. Its flavour is often described as smoky, woody, floral and jackfruit-like, quite different from arabica. Excelsa, once classed as a separate species, is now generally treated as a variety of liberica and is grown in Southeast Asia, sometimes appearing in specialist roasters’ ranges with tart, fruity notes. Coffea stenophylla, a West African species rediscovered in Sierra Leone, attracted attention after research reported it had arabica-like flavour while tolerating higher temperatures. Eugenioides, one of arabica’s parent species, appears occasionally in competition circles, with low caffeine and sweet, cereal-like flavour. For a UK café, these are conversation-starters and limited releases rather than daily options; supplies are small and inconsistent. If you offer one, explain it as a curiosity, price it as a premium filter, and give staff a short briefing. Never imply that a species is ‘healthier’ or ‘lower caffeine’ unless your roaster can back it up with data. - Liberica beans are large and irregular - Excelsa is now usually treated as a liberica variety - Stenophylla is noted for arabica-like flavour and heat tolerance - Eugenioides is a parent species of arabica - Rare species suit limited filter releases #### Yemeni coffee Yemen is where coffee drinking first flourished as a cultural habit, and the port of Mocha (al-Makha) gave its name to an entire style of coffee and, later, to the chocolate drink. Yemeni coffee is grown on terraced mountainsides, often in tiny plots, mostly using old local varieties, and processed as naturals dried on rooftops or terraces. Flavours can be intense: dried fruit, raisin, cocoa, spice and wine, with a wild, sometimes rustic edge. Supply is small, logistics are extremely difficult due to conflict and infrastructure problems, and quality varies widely. In recent years, a handful of importers have built more traceable supply chains, and research has identified distinct genetic groups of arabica in Yemen, which has added interest. Prices are high, so in UK cafés Yemeni coffee usually appears as a luxury filter or a limited retail bag. The ‘mocha’ name causes confusion: a guest ordering a mocha wants chocolate, not Yemeni coffee, and staff should never mix the two up. When telling the story of Yemeni coffee, keep it accurate and respectful; avoid romanticising hardship or implying your purchase is transformative unless the roaster can show how money reaches producers. - Coffee drinking culture first flourished in Yemen - The port of Mocha gave its name to a coffee style - Most Yemeni coffee is dried as natural - Supply is small and logistics are difficult - ‘Mocha’ on a menu means chocolate, not Yemeni coffee #### Rwandan and Burundian coffees Rwanda and Burundi produce some of East Africa’s most elegant coffees, mostly from Red Bourbon trees grown by smallholders and processed at washing stations. Expect red fruit, black tea, orange and floral notes with silky body. Both countries suffer from the ‘potato defect’, an intermittent taint linked to an insect and a bacterium, which makes a single bean smell and taste like raw potato or soil; one affected bean in a grinder can ruin a cup or a whole pour-over. It can’t be spotted in green or roasted beans, so roasters manage it by careful sorting and cupping, and cafés by tasting regularly. If you serve a Rwandan or Burundian filter and a guest says ‘this smells like potato peel’, believe them, discard the brew and grind fresh; it is not your staff’s fault. Washing stations in both countries have invested heavily in quality, and many lots are traceable to station level. Harvests run roughly from early in the year, with coffee arriving in the UK in the second half of the year. Rwandan coffee in particular often appears in UK cafés as an elegant single origin for both espresso and filter, and works well in milk if roasted to medium. - Red Bourbon is the dominant variety - Potato defect causes raw-potato aromas in single beans - Potato defect cannot be spotted visually - Coffee is processed mainly at washing stations - Lots often arrive in the UK in the second half of the year #### Peruvian, Bolivian and Ecuadorian coffees Peru is a major exporter of organic and Fairtrade arabica, much of it from smallholders in regions such as Cajamarca, Junín, Cusco and Puno. Its coffees are often soft, nutty and sweet, useful as a blend base, with standout microlots from high altitudes. Bolivia’s production has shrunk dramatically over recent decades, but small amounts of excellent, delicate washed coffee from the Yungas and Caranavi regions reach the UK. Ecuador grows both arabica and robusta; its high-altitude arabica from Loja and Pichincha has produced competition-winning coffees, including Sidra and typica lots. For a café, Peru is a good choice when you want certified organic or Fairtrade coffee at a manageable price; check certification carefully if you want to advertise it, because certification has to run through the whole chain to make claims. Bolivian and Ecuadorian coffees are typically limited releases, often more expensive, offered as guest filter. As with all South American origins, flavours are often described as ‘sweet, clean and gentle’, but the exceptions can be wild. Encourage staff to taste each new coffee rather than relying on country stereotypes, and avoid describing a whole nation’s coffee as ‘mild’ or ‘generic’ in front of guests. - Peru is a big source of organic and Fairtrade coffee - Bolivian production has fallen sharply - Ecuador grows both arabica and robusta - Certification claims must cover the whole chain - Taste each coffee rather than trusting stereotypes #### Coffee, trade history and the UK café Coffee arrived in Britain in the mid-1600s, with the first coffee houses opening in Oxford and London around the 1650s. They became places for news, debate and business; insurance and stock trading have roots in coffee-house culture. Tea overtook coffee in the eighteenth century, helped by the East India Company’s trade. Coffee’s modern UK revival came in waves: Italian espresso bars in the 1950s, especially in London’s Soho; chain coffee shops spreading in the 1990s and 2000s; and the speciality wave from the late 2000s, often credited to Australian and New Zealand baristas popularising the flat white and lighter roasts. Today the UK has a large branded coffee-shop market alongside many independents, with speciality cafés, roasteries and drive-throughs. Instant coffee still sells heavily in homes. This history helps explain British drinking habits: big milk drinks, a lingering preference for strong-tasting coffee, and a tea culture that shapes how people approach coffee. For café owners and staff, knowing the backstory makes great talking points with guests and helps when designing a menu that respects local habits, such as offering both a classic latte and a speciality filter rather than forcing one style. - Britain’s first coffee houses opened in the 1650s - Coffee houses were hubs for news and business - Tea overtook coffee in the eighteenth century - Italian espresso bars arrived in the 1950s - The flat white spread with antipodean baristas ### Processing #### Coffee harvest and picking Coffee cherries on one branch ripen unevenly, so quality starts with picking. Selective hand-picking returns to the same trees several times over the harvest, taking only ripe red (or yellow, for some varieties) cherry. Strip-picking pulls everything off a branch in one pass, green and overripe included, which is cheaper but lowers quality unless the cherry is sorted afterwards. Mechanical harvesters, common in Brazil, shake ripe cherry from trees on flat land and are increasingly selective. Sorting happens by hand on tables and in water tanks, where floaters (underdeveloped or damaged cherry) rise and are skimmed off. Ripeness is often measured by sugar level with a refractometer on farms that chase quality. Picking is hard, seasonal, low-paid labour in many origins, and the price paid for cherry is the heart of most sustainability debates. For a café owner, it explains why traceable, carefully picked coffee costs more: every return pass through a field is wages. It also explains common defects. Underripe cherry shows as astringent, grassy or peanut-like flavours, and if your espresso has a dry, papery finish that no grind change fixes, the problem may be the green coffee, not your dial-in. Talk to the roaster before blaming staff. - Cherries on one branch ripen at different times - Selective picking means several passes per harvest - Floaters are skimmed off in water sorting - Unripe cherry causes astringent, grassy flavours - Picking costs are a major part of quality premiums #### Washed process in detail Washed (or fully washed, wet-processed) coffee has its skin and much of its fruit removed before drying. Cherry goes through a pulper, which squeezes the seeds out; the seeds are still coated in sticky mucilage. They then sit in tanks, usually for somewhere between twelve hours and a couple of days, while microbes break down the mucilage; producers check by feel, waiting for the beans to lose their slime and feel gritty. Some farms use mechanical demucilagers instead of fermentation. The coffee is washed in channels, where density differences again separate lower-quality beans, and then dried on patios, raised beds or mechanical dryers to around 10 to 12 per cent moisture, still in its parchment layer. It rests for weeks before milling. Washed coffees taste ‘clean’: the flavour of the seed and its terroir shows clearly, with distinct acidity and fewer fruity-fermented notes. The process uses significant water, which is an environmental issue, and newer eco-pulpers reduce it. For café staff, washed is the reference point: if a guest asks why one coffee tastes like tea and lemon and another like jam, washed versus natural is often the answer. Washed lots also tend to be the most predictable to dial in. - Pulping removes skin, leaving mucilage on the seed - Fermentation tanks remove mucilage before washing - Coffee is dried to roughly 10–12% moisture - Washed coffees taste clean and acidity-led - The process uses a lot of water #### Natural process in detail Natural (dry-processed) coffee is dried as whole cherry, seed inside the fruit, and only hulled once dry. It is the oldest method and still the norm in Brazil, much of Ethiopia and Yemen. Cherry is spread on patios or raised beds and turned many times a day so it dries evenly and doesn’t mould; depending on climate, drying takes two to four weeks or more. As the fruit dries, sugars and fermentation compounds migrate into the seed, giving heavy body, low acidity and flavours from strawberry jam and blueberry to wine, rum and, when done badly, rotting fruit or barnyard funk. Good naturals require constant labour and careful moisture control; uneven drying produces ‘ferment’ defects and over-dried fruit makes the cup taste flat. In the café, naturals are crowd-pleasers in filter and can be brilliant in milk, where the berry sweetness reads as ‘strawberry milkshake’. They are also more variable bag to bag, so dial-in can shift more than with washed coffee. Some guests find heavily fermented naturals taste boozy or ‘off’, so staff should warn rather than oversell. Naturals use far less water than washed processing, an argument some roasters make on sustainability grounds. - Naturals are dried as whole cherry - Drying can take two to four weeks or more - Typical flavours: berry, jam, wine - Uneven drying causes ferment defects - Uses far less water than washed processing #### Honey and pulped-natural process Honey process sits between washed and natural. The cherry is pulped to remove the skin, but some or all of the sticky mucilage (miel, Spanish for honey, which is where the name comes from) is left on the seed as it dries. There is no honey involved. Costa Rican micro-mills popularised colour grades: white or yellow honey keeps little mucilage and dries fast in sun; red honey keeps more and dries slower; black honey keeps the most and is often dried shaded and slowly, giving the most fruit-forward, syrupy result. The colours describe the look of the dried parchment and the general method, but each mill defines them differently. Brazil’s pulped natural is similar and gives that country’s classic sweet, round cups. Honey coffees often offer more body and sweetness than washed coffees without the heavy fermentation of a natural, which makes them good espresso candidates. Drying sticky beans is risky: they clump and can mould, so they are turned frequently. For guests, the essential sentence is: ‘It’s called honey because of the sticky fruit left on the bean while it dries, which makes it taste sweeter.’ Correct the honey assumption politely, especially for vegans who may ask. - Honey refers to sticky mucilage, not bee honey - Colour grades vary between mills - Black honey retains the most mucilage - Brazil’s pulped natural is a related method - Often sweeter and heavier than washed #### Experimental fermentation Over the past decade, producers have borrowed from wine and brewing to create new flavour: anaerobic fermentation in sealed tanks, carbonic maceration with whole cherry under carbon dioxide, added yeast strains, lactic fermentations, extended ‘double’ fermentations and co-ferments with fruit, cinnamon or hops. Results range from extraordinary to cloying. Anaerobic naturals can taste of cinnamon, tropical fruit and boiled sweets; co-ferments may taste exactly of the added fruit because, in effect, flavour has been added. Many competition baristas use these lots, and they sell well as limited filter releases. The debate in the trade is about transparency: some roasters list co-ferments as such, others call them simply ‘fruit notes’. The honest approach in a café is to describe the method on the menu card and the till, and to brief staff so they can say ‘this has been fermented with passion fruit, which is why it tastes like that.’ Experimental lots are usually expensive and short-lived, so buy small quantities, price filter higher and avoid putting them on espresso for milk drinks, where funky notes can turn medicinal. They also age faster in the bag than clean washed coffees; drink them within a few weeks of opening. - Anaerobic fermentation happens in sealed tanks - Carbonic maceration borrows from winemaking - Co-ferments add fruit or spices during fermentation - Transparency about added flavour is a trade debate - Funky lots rarely work in milk drinks #### Drying and resting green coffee Drying is where many quality problems begin. Coffee goes from around 60 per cent moisture as fresh cherry or wet parchment to roughly 10 to 12 per cent, measured with a moisture meter. Too fast, especially in strong sun or hot mechanical dryers, and beans crack or dry unevenly; too slow, and mould or over-fermentation sets in. Raised African beds allow air underneath and are standard for quality lots; patios are cheaper but risk earthy taints. After drying, coffee rests in parchment (the ‘reposo’) for weeks to stabilise moisture before being dry-milled: hulling off parchment or dried cherry, then sorting by size, density and colour, and bagging. Water activity, a measure of how freely moisture moves in the bean, is increasingly used alongside moisture content to predict shelf life. Green coffee is then shipped in jute bags with plastic liners such as GrainPro, or in vacuum packs for top lots, because moisture and heat in shipping containers can rapidly fade flavour. Green coffee ages too: ‘past crop’ coffee tastes papery, woody and flat. For roasters and cafés, this is why the same farm can taste different six months on, and why it pays to ask when a lot arrived. - Fresh cherry starts around 60% moisture - Raised beds improve airflow while drying - Resting in parchment is called reposo - GrainPro liners protect green coffee in transit - Old green coffee tastes woody and papery #### Water at origin and wet-mill waste Wet processing produces large volumes of wastewater full of sugars and acids from coffee pulp and mucilage. Released untreated into rivers, it can strip oxygen from the water, harm fish and create smells, which is a serious environmental problem in some origins. Many mills now use settling ponds, filtration, biodigesters or ‘eco-pulpers’ that use far less water. Coffee pulp itself can be composted and returned to farms as fertiliser. The dried husks and skins of coffee cherry are also sold as cascara, brewed as a fruity tea-like drink with a taste of dried cherry, hibiscus and tobacco; in the UK, cascara has had a complicated regulatory history as a novel food, so check its current status and your supplier’s compliance before selling it. Some producers turn by-products into flour, spirits or animal feed. For a café, these topics matter when telling sustainability stories and when choosing roasters, who can explain how their partners handle waste. Cascara can be a lovely menu addition (hot, iced or as a syrup), but treat any supplier claims carefully. It is a good example of a product where the trade enthusiasm can outrun regulation, so do the due diligence. - Untreated coffee wastewater harms rivers - Eco-pulpers reduce water use - Coffee pulp can be composted - Cascara is dried coffee cherry husk - Check cascara’s UK novel food status before selling ### Buying & Sourcing #### Green coffee grading and defects Green coffee is graded by screen size (beans shaken through perforated plates measured in 64ths of an inch, so ‘screen 17/18’) and by defect count in a sample, typically 300 or 350 grams. Primary defects include full black beans, full sour beans, dried cherry pods, fungus damage, foreign matter and severe insect damage; secondary defects include partial black or sour beans, broken or chipped beans, quakers, shells and floaters. Quakers are unripe beans that don’t roast properly; they show as pale, peanut-coloured beans after roasting and taste like dry cereal or peanut skins. Speciality coffee under the Specialty Coffee Association’s traditional system has no primary defects allowed in the sample and only a small number of secondary defects, plus a cup score of 80 or above on its 100-point scale; the SCA has been introducing a newer Coffee Value Assessment approach, so expect grading language to evolve. For café owners buying roasted coffee, knowing this vocabulary helps when a roaster’s blend tastes off. Tip a bag onto a white tray and look for pale quakers, chips and odd-coloured beans; a few is normal, a handful per dose is not. Feedback with photos is more useful to a roaster than ‘it tastes weird’. - Screen size is measured in 64ths of an inch - Grading samples are typically 300–350g - Quakers are unripe beans that roast pale - Traditional speciality threshold is 80+ points - Inspect roasted beans on a white tray for defects #### Cupping protocol Cupping is how the trade tastes coffee consistently. Roasters lightly roast samples, grind them coarse, and weigh a set dose (the SCA ratio is 8.25 grams to 150 millilitres of water) into identical bowls. Testers smell the dry grounds (fragrance), pour water just off the boil, wait around four minutes, then ‘break’ the crust with a spoon and smell the aroma that rises. After skimming the floating grounds, they slurp from spoons, loudly, to spray coffee across the palate, tasting repeatedly as it cools, because defects and qualities shift with temperature. Scores cover fragrance and aroma, flavour, aftertaste, acidity, body, balance, uniformity, clean cup, sweetness and overall impression on the traditional form. Several cups of each coffee are tasted to check consistency. Spoons are rinsed between bowls to avoid cross-contamination. For a café team, a weekly cupping of your own coffees, a competitor’s and an old bag teaches more than any manual. It builds a shared vocabulary so that ‘bright’, ‘flat’ and ‘baked’ mean the same thing to everyone. Keep it simple: three to five coffees, blind if possible, and agree on one word each. Many UK roasters run open cuppings for wholesale clients; ask. - SCA cupping ratio: 8.25g per 150ml - The crust is broken at around four minutes - Slurping aerates coffee across the palate - Multiple cups per sample test uniformity - Weekly staff cuppings build shared vocabulary #### Coffee flavour wheel and tasting language The Coffee Taster’s Flavor Wheel, produced by the SCA with World Coffee Research, groups flavours from general categories in the centre (fruity, floral, sweet, nutty/cocoa, spices, roasted, green/vegetative, sour/fermented, other) out to specific notes like blackcurrant, jasmine or brown sugar. It also links to a sensory lexicon with reference standards, so ‘blackberry’ means something agreed. Tasting notes on bags are comparisons, not ingredients, yet a surprising number of guests assume chocolate notes mean added chocolate. Train staff to say ‘it reminds us of’ rather than ‘it has’. Useful vocabulary for the floor: acidity is brightness or tang (good when balanced, sour when underextracted); body is weight and texture; sweetness is perceived sugariness; bitterness is normal in moderation; astringency is a drying sensation, often from overextraction or unripe beans. Aftertaste is what lingers. Most customers don’t want the wheel; they want a simple steer. A three-way split works well: chocolate and nutty, fruity and bright, or something in between. Matching a guest’s habits (do you take sugar? do you like dark chocolate or fruit sweets?) to one of three coffees sells more filter than any detailed tasting note, and avoids sounding pompous. - The flavour wheel was produced by the SCA and World Coffee Research - Tasting notes are comparisons, not added flavourings - Astringency is drying, not the same as bitterness - Sourness often signals underextraction - Three-way flavour splits help guests choose #### Direct trade, relationship coffee and certifications Coffee reaches a UK café through a chain: producer, sometimes a cooperative or exporter, an importer, a roaster, then you. ‘Direct trade’ and ‘relationship coffee’ describe roasters buying from the same producers year after year, often visiting and paying agreed premiums; the terms are not regulated, so they mean whatever the roaster backs them up with. Good roasters publish prices paid (FOB or farm-gate) in transparency reports. Certifications are regulated by their schemes: Fairtrade sets a minimum price and a premium paid to cooperatives; Rainforest Alliance (merged with UTZ) focuses on farm practices; organic certification in the UK requires the product to be certified by an approved control body, and you can’t call a drink organic on a menu unless the supply chain, including your business in some cases, is covered. Speciality coffee often sits outside certification, with roasters arguing their prices already exceed minimums. For the café, be careful with claims: ‘ethically sourced’ on a board invites a question you should be able to answer. Ask your roaster for the origin, producer, price paid or certification, and keep a one-page sheet behind the bar. Claims must be accurate under consumer protection law; vague green or ethical claims draw scrutiny from regulators. - ‘Direct trade’ is not a regulated term - Fairtrade sets a minimum price plus a premium - Rainforest Alliance merged with UTZ - Organic claims need certification across the chain - Keep a sourcing fact sheet behind the bar #### C price and coffee costs The ‘C price’ is the benchmark futures price for arabica traded on the ICE exchange in New York, quoted in US cents per pound; robusta trades in London in US dollars per tonne. Commodity coffee is priced as the C plus or minus a differential for origin and quality. Speciality lots are usually priced well above the C, but the market still drags costs up and down: when the C spikes, as it did dramatically in 2024 and into 2025, roasters face higher costs across the board, and UK cafés saw wholesale price rises. Exchange rates matter too, because green is bought in dollars; a weak pound makes coffee dearer in the UK. Freight, insurance, roasting labour, energy, packaging and roaster margin sit on top. For a café, roasted coffee is still a small part of the price of a drink, but a jump of a few pounds per kilo adds up over a year. Watch your price list, ask your roaster about forward contracts or fixed pricing for six months, and recalculate cost per drink whenever it changes. When you raise menu prices because of coffee costs, a short, honest note at the till lands better than silence, but avoid claiming more of the rise is coffee than really is. - The C price is the arabica futures benchmark in New York - Robusta futures trade in London - Green coffee is bought in US dollars - Coffee prices spiked sharply in 2024–25 - Ask roasters about fixed-price contracts #### Importers and the green supply chain Most UK roasters don’t buy straight from farms; they buy through importers and green traders who handle the hard parts: pre-shipment samples, contracts, finance, shipping, customs, warehousing and quality control. Importers often pre-finance producers, absorb the risk of lots that arrive faded, and hold stock in UK or European warehouses so roasters can buy a few bags at a time. Coffee typically arrives at ports like Felixstowe or via Antwerp and Hamburg, and is stored in bonded or duty-paid warehouses. Green coffee imported into the UK from many origins has no tariff, but paperwork and food-safety standards still apply. Roasters receive an offer sample, cup it, approve a pre-shipment sample, then an arrival sample to check nothing changed in transit. Spot coffee is available now from a warehouse; forward contracts commit to a future harvest. For café owners who want to understand price and quality, asking your roaster who their importer is and when a lot landed is a useful conversation. If you are thinking about roasting yourselves, building relationships with two or three importers who sell small quantities is the first step, long before buying a roaster. Many run sample programmes and green-buying training. - Importers handle finance, shipping and quality control - Offer, pre-shipment and arrival samples are cupped - Spot coffee is in a warehouse now - Forward contracts lock in future harvests - Many importers sell small lots to new roasters #### Single origin, single estate and microlot Single origin can mean anything from ‘from one country’ to ‘from one farm’s single plot’. Single estate or single farm narrows it to one producer; a microlot is a small, separately processed portion, often one variety, one plot or one picking day; a nanolot is smaller still. Regional or station blends combine many smallholders’ coffee from one area. None of these terms is legally defined in the UK, so they are only as meaningful as the roaster’s detail. Blends combine coffees from different origins, usually for consistency, balance in milk, and cost control. Single origins are usually seasonal and change flavour as the lot ages. In a café, a clear structure helps guests: one house blend for consistency, one rotating single origin for espresso or filter, and perhaps a decaf. Price single origins a little higher and explain why. When a guest asks what ‘single origin’ means, a plain answer is best: ‘it comes from one place, so it has a more distinct flavour, and it changes every few weeks.’ Avoid implying single origin is automatically better; a carefully built blend is often more satisfying in a flat white, and consistency is what most regulars value. - ‘Single origin’ has no legal definition - Microlots are small, separately processed portions - Blends are often built for consistency and milk - Single origins are seasonal and change over time - A blend plus a rotating single origin is a clear menu structure #### Choosing a wholesale roaster Choosing a roaster is one of the biggest decisions a UK café makes, because it shapes flavour, price, training and often equipment. Start by cupping and tasting several roasters’ house espressos in milk and black, side by side, using your own milk. Then compare the full offer: price per kilo (and how often it changes), minimum orders, delivery days and lead times, roast-date freshness on arrival, packaging (bulk bags or tubs), barista training, technician support, equipment loans or leases, marketing support such as branded cups or menus, and whether they’ll help you dial in on opening day. Some roasters offer machines on loan in exchange for a minimum monthly coffee purchase; read the contract carefully for exit terms, servicing responsibilities and what happens if you switch suppliers. Ask for references from similar businesses, and visit if you can. A good roaster will taste your coffee in your shop and give honest feedback, not just sell more bags. Consider whether you want exclusivity: some roasters won’t supply another café on the same street, others will. Finally, decide whether the roaster’s brand helps you (a well-known local name) or competes with you; some cafés prefer a quieter, white-label arrangement. - Taste house espressos in your own milk - Compare price, freshness, training and support - Machine loans usually require minimum coffee purchases - Read exit terms in equipment contracts carefully - Ask for references from similar businesses #### Coffee freshness and stock rotation Coffee freshness is a practical stock-control problem. Roasted beans peak somewhere between about a week and a month or so after roasting, depending on roast and packaging, then fade. A café using 10 kilos a week should order little and often, ideally weekly, so bags are opened within their window. Mark each bag with its delivery date and opening date, keep them sealed in a cool, dark place (never in the fridge, where condensation and odours get in), and rotate first in, first out. Hopper management matters: only fill the hopper with what you’ll use in a few hours, because beans in a clear hopper under warm lights stale faster. At close, many cafés empty hoppers into airtight tubs. Single-dose grinding avoids hoppers altogether and is common for filter. Watch for signs of stale coffee: crema thins and pales, shots run faster for the same grind, flavours go flat and woody, and the bloom on filter shrinks. Order quantities should rise ahead of bank holidays and fall before closures; running out of house blend is a crisis, but tipping three stale bags in the bin is wasted margin. A simple spreadsheet of weekly usage against covers makes ordering far easier. - Roasted beans peak roughly one to four weeks after roasting - Never store coffee in the fridge - Fill hoppers only with a few hours’ worth - Stale coffee shows as thin crema and faster shots - Track weekly usage to order accurately #### Coffee origins on the menu Origin information can sell coffee or bore guests, depending on how it’s presented. A good café menu tells guests just enough: the coffee name, origin, process and two or three tasting notes, plus a price. Some cafés add producer names and altitude on a separate card or QR code for those who want it. Keep the language plain and accurate: ‘Ethiopia, washed, jasmine, lemon, honey’ is clear. Avoid jargon like ‘SL28/34, 1,850 masl, 72-hour anaerobic’ on the main board unless your crowd wants it. Update the board whenever the coffee changes, and remove sold-out lots promptly; nothing irritates a regular more than ordering a coffee that ran out last week. Train staff with a one-line description of each coffee and a ‘who will like it’ line, such as ‘if you like fruit teas, try this filter’. Pricing should reflect cost, not just novelty. If you have a guest roaster, credit them properly. For takeaway-heavy shops, origin information can live on retail bags and social media rather than the menu. For sit-in cafés, a small card on the table with today’s coffees invites conversation and helps upsell filter or a second cup. - Keep menu origin info short and accurate - Use QR codes or cards for deeper detail - Remove sold-out coffees promptly - Give staff a ‘who will like it’ line - Credit guest roasters properly #### Specialty Coffee Association and trade bodies The Specialty Coffee Association (SCA) is the main global trade body for speciality coffee, formed in 2017 by merging the American and European associations. It runs the Coffee Skills Program, a modular education system covering introduction to coffee, barista skills, brewing, green coffee, roasting and sensory skills at foundation, intermediate and professional levels, taught by authorised trainers in the UK and elsewhere. It also sets brewing and water standards, publishes research and runs or licenses competitions through World Coffee Events, including the World Barista Championship, with national heats in the UK. The UK has its own coffee community events such as the London Coffee Festival, and trade shows where equipment and roasters exhibit. The Coffee Quality Institute runs the Q Grader programme for professional cuppers. For café owners, SCA courses offer structured training for staff, though plenty of excellent baristas learn on the job and through roaster training. Certificates help with hiring and progression, but practical skill matters more on the bar. If you are budgeting for training, combining a foundation barista course for new staff with in-house coaching and regular cupping usually gives the best return. Check current course names and prices directly, because programmes are updated. - The SCA formed in 2017 from a merger - The Coffee Skills Program is modular - World Coffee Events runs international competitions - The Coffee Quality Institute runs Q Grader certification - Practical skill matters more than certificates on bar #### Coffee seasonality calendar Coffee is an agricultural crop with harvest seasons, and the best-tasting lots arrive fresh a few months after harvest. As a rough guide: Central American and Colombian main crops are harvested around the end of one year into the spring of the next, arriving in the UK from mid-year; Ethiopian and Kenyan harvests run late in the year into early the next, with lots landing in the UK in spring and summer; Brazil harvests mid-year, arriving later in the year; Rwanda and Burundi harvest early in the year, arriving later; Indonesian and some Colombian regions harvest more continuously. Exact timing varies by region and year. For cafés, this means single origins change through the year, and blends are tweaked to keep flavour consistent as components change. A good roaster explains these shifts and adjusts recipes. Seasonality is a marketing opportunity: ‘new-crop Kenya just landed’ is real news to coffee fans. It also explains why the same coffee may taste brighter on arrival and flatter months later. Plan menus around it, and ask your roaster to share a rough arrival calendar so you can promote launches and avoid gaps when a favourite runs out. - Coffee is best a few months after harvest - Central American lots often land mid-year - Ethiopian and Kenyan lots often land in spring and summer - Brazilian coffee usually arrives later in the year - Roasters tweak blends as components change ### Roasting #### Roasting chemistry basics Roasting turns a hard, grassy green seed into something brittle and aromatic through heat-driven chemistry. Early in the roast, the bean dries out, losing moisture and turning from green to yellow, with a smell like hay or toast. Then browning reactions take over: Maillard reactions between sugars and amino acids create hundreds of aroma compounds and brown colour, while caramelisation breaks sugars down into sweet and, later, bitter compounds. Chlorogenic acids, abundant in green coffee, break down as roasting continues, which changes perceived acidity and bitterness. Gases build up inside the bean, mostly carbon dioxide, causing ‘first crack’, an audible popping as the bean expands and releases steam and gas. Roast longer and ‘second crack’ arrives, a quieter, faster crackle as the bean structure fractures and oils migrate to the surface. Beans lose roughly 12 to 20 per cent of their weight, mostly water, and nearly double in volume. In practical terms: lighter roasts keep origin acidity and fruit; medium roasts balance sweetness and body; dark roasts trade origin character for roast flavour, bitterness and heavier mouthfeel. Knowing the basics helps baristas explain why a ‘strong’ dark roast actually contains roughly the same caffeine as a lighter one by weight. - Maillard reactions create browning and aroma - First crack is an audible pop as gases escape - Second crack brings oils to the surface - Beans lose about 12–20% weight during roasting - Roast level barely changes caffeine by weight #### Roast profiles and development A roast profile is the plan of temperature over time. Roasters track bean temperature with probes and watch the rate of rise (RoR), how quickly temperature climbs each minute. A typical speciality roast on a drum roaster lasts somewhere around nine to fourteen minutes. Phases are often split into drying, Maillard (browning) and development, the time from first crack to the end of the roast. Development time ratio (DTR), development as a percentage of total time, is a common guide, with many filter roasts sitting somewhere near 15 to 25 per cent, though that is a rule of thumb, not a law. A smooth, steadily declining RoR is generally associated with sweeter, cleaner cups. Problems include a ‘crash’ (RoR drops sharply after first crack, leading to flat, baked flavours) and a ‘flick’ (a late surge that can bring roasty or smoky notes). Underdeveloped coffee tastes grassy, sour and peanut-like, and resists extraction on the grinder. Overdeveloped coffee tastes roasty, ashy and hollow. Software like Cropster or Artisan logs each roast. For a café buying from a roaster, the practical point is that the same green coffee can taste very different depending on profile, which is why espresso and filter roasts of the same bean are sometimes sold separately. - Rate of rise is temperature increase per minute - Typical speciality roasts last around 9–14 minutes - Development time ratio is a guide, not a rule - A crash after first crack causes baked flavours - Underdeveloped coffee tastes grassy and resists extraction #### Espresso roast versus filter roast Many speciality roasters sell the same coffee as an ‘espresso roast’ and a ‘filter roast’, or label everything ‘omni’ for both. The logic: espresso concentrates flavour and acidity into a tiny volume, extracted quickly under pressure, so a slightly more developed roast helps solubility and tames sharpness, especially in milk. Filter brewing is gentler and more dilute, so a lighter roast can show origin clarity and delicate aromatics without tasting thin. Omni roasts aim for a middle ground and simplify stock for both roaster and café. In practice, using a very light filter roast as espresso often gives sour, thin shots that need very fine grinding, long ratios and high temperatures to taste good, and can choke the grinder. Using an espresso roast for filter can taste flat, roasty or bitter. For a café menu, it is usually best to buy espresso-specific roasts for your house blend and use filter roasts on batch brew or pour-over. If you sell retail bags, label which roast it is and ask what equipment the customer uses at home; someone with a cafetière and a supermarket grinder will probably prefer the espresso or omni roast. Roasters are usually happy to advise on this when you set up wholesale. - Espresso roasts are usually slightly more developed - Omni roasts aim to suit both methods - Light filter roasts can taste sour as espresso - Espresso roasts can taste flat as filter - Ask retail customers what brewer they use #### Coffee roaster types Drum roasters dominate speciality: a rotating steel drum is heated by gas or electric burners, with hot air drawn through by a fan, combining conductive heat from the drum with convective heat from airflow. Classic, solid-drum machines from makers such as Probat, Giesen, Diedrich and Loring (which uses a recirculating convection design) are common in UK roasteries. Fluid-bed (hot-air) roasters suspend beans in a column of hot air, roasting quickly and evenly with less contact heat, and are popular for sample roasting and some production. Smaller electric roasters, sized from a few hundred grams to a few kilos, have made in-café roasting more realistic, though ventilation and smoke control are the real constraints. Batch capacities are described in kilos, and roasters usually run below maximum for best results. Commercial roasting produces smoke, chaff and odours; in the UK, planning permission, extraction, building regulations and your local authority’s environmental health team will be involved if you install one, and afterburners or catalytic converters may be needed to control smoke and smells in residential areas. Fire risk is real: chaff collectors must be emptied and roasters must never be left unattended. Insurance companies will ask detailed questions about the setup before covering it. - Drum roasters use both conduction and convection - Fluid-bed roasters suspend beans in hot air - Loring roasters recirculate hot air - Smoke control may require an afterburner - Chaff collectors are a key fire risk #### Roasting in-house: is it worth it? Roasting your own coffee sounds romantic, and for some UK cafés it works: you control flavour, sell retail bags with a higher margin, and wholesale to other businesses. But the economics are more complex than green costs versus roasted price. A decent small production roaster with installation, extraction, afterburner and ductwork can easily reach five figures, often more, and needs a suitable space that planning and environmental health will accept. You need a trained roaster, which takes months of practice and wasted batches, plus green buying knowledge, quality control (cupping every batch), packaging equipment, labels that meet food-labelling rules, and stock management. Roasting a few kilos a week rarely pays back; it starts to make sense when you can sell volume through wholesale and online retail. Many cafés compromise by working with a roaster to develop a custom blend under their own brand (white label), which gives the story without the capital or risk. Another route is sharing a roastery: some UK roasters rent time on their machines. If you do roast, plan carefully around consistency: guests notice when the house espresso tastes different every week, and staff waste time re-dialling. A roast log, a reference sample and regular cupping are non-negotiable. - A small production setup can easily cost five figures - Planning and environmental health will be involved - White-label blends offer branding without roasting - Some roasters rent machine time - Every batch should be cupped #### Resting roasted coffee and degassing Freshly roasted coffee releases carbon dioxide for days to weeks. Brew it too soon and the gas fights extraction: espresso shots spurt, crema is huge but unstable, and flavours taste sharp, uneven or ‘green’. Filter coffee blooms violently and can taste hollow. Most roasters recommend resting espresso roasts for roughly a week or more, sometimes up to a few weeks for light roasts; filter coffee is often good from a few days after roasting. Valves on coffee bags let gas out without letting air in; they’re why bags swell slightly but don’t burst. After that rest period, coffee gradually stales as aromatics fade and oils oxidise. Whole beans keep well for several weeks in a sealed bag away from light and heat; ground coffee stales within hours. For a café, order on a rolling rota so you always use coffee in its sweet spot. Write roast date and opening date on each bag, and rotate stock first in, first out. If a new delivery tastes harsh, check the roast date before changing the grind. Freezing can preserve beans for longer if done in airtight portions and not repeatedly thawed; some cafés freeze single doses of premium filter lots for consistency and longevity. - Roasted coffee releases CO2 for days to weeks - Espresso roasts often need about a week’s rest - One-way valves let gas out without letting air in - Ground coffee stales within hours - Freezing in airtight portions extends freshness #### Coffee packaging and labelling Retail coffee bags have several jobs: keep oxygen, light and moisture out, let carbon dioxide escape, and carry legally required information. Most use multilayer films with foil or metallised layers, plus a one-way valve. Recyclable and compostable bags exist, but claims must be accurate: ‘compostable’ often means industrial composting, which most UK households can’t access, and misleading environmental claims can attract regulatory action under consumer protection law and the Competition and Markets Authority’s guidance on green claims. Pre-packed food sold in the UK must show the name of the food, net quantity in metric units, a best-before date, the name and UK address of the business responsible, and storage conditions where needed; coffee doesn’t usually need a full nutrition table if it falls under exemptions for single-ingredient products, but check if you add anything. Flavoured coffees may contain allergens that must be emphasised in the ingredients list. Roast date isn’t a legal requirement, but speciality customers expect it. Net weight must comply with weights and measures rules, often enforced by local trading standards. For cafés selling a roaster’s bags, the roaster is usually responsible for labelling, but you must store and display them properly and not sell past best-before. - One-way valves let CO2 escape - ‘Compostable’ often means industrial composting only - Labels need name, net weight, best-before and business address - Roast date is expected but not legally required - Trading standards enforce weights and measures #### Defects in the cup Learning to recognise cup defects helps a café work out whether a problem is in the green coffee, the roast, storage or brewing. Ferment or overripe notes taste like vinegar, rotten fruit or alcohol and usually come from processing. Phenolic or medicinal flavours, like plasters or iodine, can come from contamination or certain defects. Earthy, musty or mouldy tastes point to damp storage or poor drying. Baggy or papery flavours come from old green coffee or long storage in jute. Potato defect (East Africa) gives raw potato. Roast defects include baked (flat, bready, from stalled roasts), scorched (burnt patches on beans), tipped (burnt bean ends), and underdeveloped (grassy, sour, peanut). Staleness gives cardboard and flat, lifeless flavour. Brewing problems, by contrast, are sourness and thinness from underextraction, or bitterness and dryness from overextraction, plus taints from dirty equipment: rancid oil from uncleaned group heads or grinders tastes like old nuts or crayons. A simple diagnostic routine is to brew the same coffee on a clean filter set-up: if the defect persists, it’s in the coffee; if it vanishes, look at your espresso machine and grinder cleaning. Report persistent issues to your roaster with roast dates. - Ferment defects taste of vinegar or rotten fruit - Baked roasts taste flat and bready - Rancid oil from dirty kit tastes like old nuts - Brew on clean filter to isolate coffee defects - Report issues to the roaster with roast dates ### Espresso Craft #### Espresso recipe: dose, yield, time Every espresso recipe has three numbers: dose (dry coffee in the basket, in grams), yield (liquid espresso in the cup, weighed in grams, not measured in millilitres because crema distorts volume) and time (seconds from pressing the button to stopping). A common modern starting point is a ratio of about 1:2, such as 18 grams in, 36 grams out, in around 25 to 32 seconds, but plenty of good cafés run 1:1.5 ‘ristretto-style’ recipes for milk or 1:2.5 and longer for lighter roasts. The ratio controls strength and flavour balance; the grind controls flow rate and therefore time and extraction. Treat time as a result, not a target: if the shot tastes right at 35 seconds, that’s fine. Write the recipe on a card at the grinder and make sure every barista uses the same numbers, scales and basket. Pick your dose to suit your basket: an 18-gram basket wants roughly 18 grams, and overfilling it can push the puck against the shower screen. When the house coffee changes, agree a new recipe with your roaster, and record any changes through the day in a dial-in log. Consistency of recipe matters more than the exact numbers, because regulars notice when their flat white changes from shift to shift. - Weigh yield in grams, not millilitres - A 1:2 ratio is a common starting point - Ratio controls strength; grind controls flow - Treat shot time as a result, not a target - Match dose to basket size #### Dialling in step by step Dialling in means adjusting grind (and sometimes dose or yield) until the espresso tastes right. Do it at the start of every day and after any big change in temperature, humidity or coffee batch. Start with the agreed recipe. Pull a shot, weigh and time it, and taste it, ideally black and also in milk if most drinks are milk-based. If it runs fast and tastes sour, thin or salty, grind finer. If it runs slow and tastes bitter, dry or harsh, grind coarser. Change one variable at a time, and make small grind steps, because many grinders need a purge shot after adjustment to clear old grounds held in the chute. Once the time is in range, use taste to fine-tune ratio: lengthen yield slightly if a shot is intense and sour-sweet; shorten if it tastes thin or bitter at the end. Record each step in a dial-in sheet (grind setting, dose, yield, time, taste note). Train every opening barista to do this, not just the head barista, but agree that only one person adjusts the grinder during service. Expect the grind to drift as the grinder warms up in a busy morning; recheck after the first rush. - Dial in at the start of every day - Fast and sour: grind finer - Slow and bitter: grind coarser - Purge after grind changes - Only one person adjusts the grinder during service #### Extraction and strength explained Extraction is how much of the coffee’s soluble material ends up in the drink; strength is how concentrated that drink is. They are different. Extraction yield (EY) is the percentage of the dry coffee’s mass dissolved into the cup; for many brews, good flavour often sits roughly in the high teens to low twenties per cent, though the ‘ideal’ depends on coffee and taste. Strength is measured as total dissolved solids (TDS), the percentage of the drink that is dissolved coffee; espresso is typically somewhere around 8 to 12 per cent TDS, filter around 1.2 to 1.5 per cent. Underextraction tastes sour, salty, thin and short; overextraction tastes bitter, astringent, hollow and drying. The order matters: acids dissolve early, sugars and heavier compounds later, bitter compounds throughout, increasingly at the end. You can have a strong but underextracted shot (short ratio, coarse grind) or a weak but well-extracted brew (dilute filter). Explaining this to staff helps them avoid fixing the wrong problem: a ‘weak-tasting’ flat white might need a stronger ratio, not a finer grind. Refractometers measure TDS; with dose and yield you can calculate extraction, which is useful for training and troubleshooting. - Extraction is how much coffee dissolves - Strength is concentration in the cup (TDS) - Espresso is roughly 8–12% TDS - Underextraction tastes sour; overextraction tastes bitter and dry - Strength and extraction can be adjusted separately #### Refractometers in the café A coffee refractometer measures total dissolved solids by how light bends through a sample. Brands like VST and Atago are common in speciality. To use it on espresso, stir the shot, take a small sample, let it cool to room temperature (some cafés filter espresso samples with syringe filters for accuracy), zero the device with distilled or the same water you brew with, and read the TDS. With dose and yield, extraction yield is calculated as TDS times beverage weight divided by dose. Refractometers are great training tools: they show new baristas what changes in grind actually do, help settle arguments, and give a numerical target when tasting is uncertain, such as early in the morning. They’re less useful as rigid targets in service, because flavour, not numbers, is the goal and readings vary with sample handling. A café might check one shot per shift and log it. They’re also handy for batch brew, where you can measure strength consistency between brews. Prices vary widely, from fairly affordable to several hundred pounds for top models. If budget is tight, invest in a reliable grinder and scales first; a refractometer helps most once staff already taste carefully and the basics are consistent. - Refractometers measure TDS via light refraction - Samples should cool before reading - Zero the device with your brewing water - Extraction = TDS × beverage weight ÷ dose - Use them for training more than service targets #### Puck preparation Puck preparation covers everything between grinding and locking in the portafilter: dosing evenly, breaking up clumps, levelling, and tamping. The aim is a uniform bed of coffee so water flows evenly, avoiding channelling, where water punches through weak spots and overextracts some areas while underextracting others. Steps in many cafés: dry and clean the basket, grind into it (or a dosing cup), distribute with a tool or a WDT (Weiss distribution technique) needle tool that stirs out clumps, level with a distributor, then tamp straight and firm. Tamp pressure matters less than consistency and keeping the tamp level; most modern guidance says tamp firmly until the coffee stops compressing rather than chasing a specific kilogram figure. Avoid tapping the portafilter after tamping, which can crack the puck. Calibrated tampers, which click at a set pressure, and auto-tampers (machines like Puqpress) improve consistency and reduce wrist strain for busy baristas, a real occupational health consideration. Signs of poor prep: spurting, uneven flow from spouts, pale streaks in a bottomless portafilter, and wet or holed pucks. In a rush, prep often slips first, so build it into muscle memory with a fixed routine and the right tools at each station. - Uneven pucks cause channelling - WDT tools break up clumps - Level tamping matters more than exact pressure - Auto-tampers reduce wrist strain - Bottomless portafilters reveal channelling #### Bottomless portafilters A bottomless (naked) portafilter has its base cut away, so you can watch espresso emerge directly from the basket. It’s an honest training tool: a good shot shows dark drops forming evenly across the basket, merging into one central stream that turns golden and blonde as it finishes. Problems are obvious. Spritzing and spraying indicate channelling, often from clumps, uneven distribution, or a cracked puck. One side flowing early suggests uneven tamping or dosing. A pale streak running through the shot shows a channel. Blonding very early can signal a coarse grind or stale coffee. Many cafés use a bottomless portafilter for training and dialling in, then switch back to spouted portafilters in service so shots can be split into two cups or so baristas can avoid the occasional spray on the counter. The downside in service: the shot drops straight into one cup, and any spraying makes a mess and wastes coffee. They also make a clear visual statement for guests who like watching coffee being made. Keep them clean; coffee oils and residue around the open base can build up quickly. Pair with a mirror on the drip tray to see the underside without bending down. - Bottomless portafilters show extraction from beneath - Spraying indicates channelling - Pale streaks reveal channels - Often used for training and dialling in - A drip-tray mirror helps viewing #### Baskets and precision filters The filter basket is a small, cheap part that significantly affects espresso. Standard baskets come with commercial machines; precision baskets (from makers such as VST and IMS) have more consistent hole sizes and patterns, giving more even flow and making dialling in more predictable. Baskets come in sizes such as 14, 18, 20 and 22 grams, plus ridged and ridgeless designs. Use the size your recipe needs; a deep, large basket underfilled leaves too much headspace, and a small basket overfilled presses the puck against the shower screen and leaves a print. Some baskets are coated or ‘competition’ versions with special mesh. Baskets wear: holes enlarge and deform with cleaning and knocking, so many cafés replace them periodically. Match all baskets across group heads, because mixed baskets give different flows and confuse dial-in. Clean them daily by soaking in a suitable espresso machine cleaner solution to remove oils, which taste rancid if left. When changing baskets, re-dial; a new precision basket may need a slightly different grind. Keep spare baskets in a labelled box. For training, it’s worth showing staff the difference between a cheap basket and a precision one using a bottomless portafilter. - Precision baskets give more consistent flow - Common basket sizes are 14–22g - Overfilled baskets mark the shower screen - Match baskets across all groups - Soak baskets to remove rancid oils #### Single, double and triple shots UK menus are inconsistent about shots. Many speciality cafés use a double shot, often around 18 grams of coffee, as the base for every drink, while chains and some independents use single shots for small drinks and doubles for larger. Triples or ‘extra shot’ options are common for large lattes. Some cafés split a double into two cups, using spouted portafilters, so each drink gets a ‘single’ of around 9 grams’ worth. Whatever you do, be clear and consistent: guests should know what they’re getting when they ask for an extra shot, and the till should charge correctly. Training note: splitting shots requires good spouts and even flow; uneven splits mean one drink is stronger. Caffeine varies with coffee and recipe, so avoid quoting exact caffeine numbers unless your roaster can give lab data, but staff should be able to say ‘our standard drinks have a double shot’ to help guests manage their intake, and point pregnant guests and others watching caffeine to decaf or half-caf options. NHS guidance advises pregnant people to limit caffeine to 200mg a day, so a clear shot policy genuinely helps customers. Price extra shots to reflect coffee cost plus labour, often somewhere around 40 to 80 pence in UK cafés. - Many speciality cafés use a double as standard - Spouted portafilters can split shots - Be consistent about what an extra shot means - NHS guidance: up to 200mg caffeine a day in pregnancy - Extra shots are commonly priced at tens of pence #### Ristretto and lungo Ristretto (Italian for restricted) traditionally means a shorter espresso, using the same dose but less water, giving a more concentrated, syrupy, sweeter-tasting shot with less bitterness from late extraction. In practice, cafés produce ristretto either by stopping early or by grinding finer; the latter tastes different because extraction rate changes. Lungo (long) uses more water through the puck for a longer, more dilute, often more bitter shot; it isn’t the same as an Americano, where hot water is added to a normal espresso. Many speciality cafés now run ‘ristretto-style’ ratios (around 1:1.5) as default for milk drinks, and some menu a ‘ristretto flat white’. If you offer ristretto, decide the recipe and train it. Guests ordering a ‘ristretto’ often want intensity without bitterness, while lungo fans may be used to Nespresso-style lungo capsules. Explaining options: ‘ristretto is shorter and sweeter; lungo is longer and lighter but can be more bitter; an Americano is espresso topped with hot water.’ Price ristretto the same as espresso unless you use extra coffee. Lungo is rarely ordered in UK cafés but cheap to offer. Be aware that some guests ask for ristretto to mean ‘strong’; check what they actually want. - Ristretto is a shorter, more concentrated shot - Lungo pushes more water through the puck - Lungo is not the same as an Americano - Ristretto-style ratios suit milk drinks - Clarify what guests mean by ristretto #### Pre-infusion and pressure profiling Traditional espresso machines push water at around 9 bar of pressure. Pre-infusion wets the puck at low pressure for a few seconds before full pressure, helping to reduce channelling and allowing finer grinds or lighter roasts to extract more evenly. Many machines include some form: line-pressure pre-infusion, a pre-infusion chamber, or programmable low-pressure phases. Pressure profiling goes further, letting baristas vary pressure through the shot, such as ramping up, holding, and declining. Machines from brands such as La Marzocco, Slayer, Victoria Arduino, Sanremo and Decent offer different approaches, and flow profiling (controlling flow rate rather than pressure) is increasingly common. Results can be impressive with light roasts and single origins, giving sweetness and clarity, but profiling adds complexity: more variables to train, record and keep consistent. For most UK cafés serving milk-heavy menus, a stable machine with simple pre-infusion and good temperature stability matters more than advanced profiling. If you invest in profiling, keep a small set of agreed profiles for house blend, single origin and decaf, rather than letting each barista experiment. Record profiles alongside recipes. Remember that a machine’s headline pressure is not what reaches the puck at every moment; observe and taste rather than relying on gauges. - Classic espresso uses about 9 bar pressure - Pre-infusion wets the puck gently first - Pressure profiling varies pressure during the shot - Flow profiling controls flow rate instead - Keep a small set of agreed profiles #### Brew temperature for espresso Espresso is commonly brewed somewhere around 90 to 96°C, with many cafés landing near 93 to 94°C. Higher temperatures increase extraction: lighter roasts and dense, high-grown coffees often benefit from hotter water, while dark roasts may taste harsh unless brewed cooler. Temperature stability matters as much as the setting: multi-boiler machines, saturated groups and PID controllers keep water steady through busy service. Heat-exchanger machines can run hotter after idle periods and need a ‘cooling flush’ to reset. Altitude is not a factor for UK cafés, but ambient temperature and steam demand are; a machine running constant milk steaming may lose temperature stability if undersized. Changes of temperature by a degree or two can shift taste noticeably, though grind and ratio are the main levers. When dialling in, keep temperature fixed unless a coffee clearly needs it; if a light roast stays sour despite finer grind and longer ratio, raise temperature slightly. Decaf often benefits from slightly lower temperatures. If your machine shows different temperatures at the group and boiler, ask your technician which reading matters. Record the temperature setting on the recipe card to avoid confusion after servicing, because engineers sometimes reset values to factory defaults. - Espresso is typically brewed around 90–96°C - Higher temperature increases extraction - PID controllers improve stability - Heat-exchanger machines may need cooling flushes - Engineers may reset temperatures during servicing #### Espresso troubleshooting guide Most espresso problems fall into a few patterns. Sour, thin and quick: grind finer, check dose, check coffee freshness (very fresh coffee also tastes sharp). Bitter, harsh and slow: grind coarser, check dose isn’t too high, check for dirty equipment. Both sour and bitter at once: channelling, so check puck prep, basket and shower screen. Huge, bubbly crema and erratic flow: coffee is too fresh. Thin, pale crema and fast flow: coffee is stale or grind too coarse. Shot time drifting during service: grinder warming up (adjust coarser as it heats) or humidity changing. One group behaves differently: check that group’s shower screen, gasket, flow restrictor and basket. Shots taste rancid or ashy: clean the group heads, portafilters and grinder. Everything tastes flat: check water filtration and hardness. Watery, weak-tasting milk drinks: shot too long for the cup size, or milk ratio too high. Hard-to-diagnose issues often come from inconsistent dosing; weigh every dose rather than relying on timed grinders until you trust them. Teach staff to taste with a spoon before serving, especially after any change. Write this list on a laminated card at the bar so new staff don’t guess, and log problems so the technician sees patterns. - Sour and fast: grind finer - Bitter and slow: grind coarser - Sour and bitter together suggest channelling - Thin crema can mean stale coffee - Rancid tastes point to dirty equipment #### Scales on the bar Scales are one of the cheapest upgrades for consistent coffee. Bar scales should be fast-reacting, accurate to 0.1 gram, waterproof or splash-resistant, and small enough to fit on drip trays. Many cafés use dedicated coffee scales with built-in timers, and some espresso machines include integrated scales in the drip tray for gravimetric shots. Use them to weigh doses (in the portafilter) and yields (in the cup), especially when dialling in and training. In busy service, some cafés weigh every dose and every shot; others weigh periodically to check consistency, relying on gravimetric grinders or volumetric machines between checks. Scales also matter for filter recipes and tea. Batteries die at the worst times, so keep spares, or use rechargeable scales and charge them overnight. Calibrate periodically with a known weight. Clean scales after service, as milk and coffee residue builds up. Don’t forget scales for portioning cakes, syrups and sauces too; cost control often begins with weighing. If staff resist weighing, show them the difference in coffee usage between weighed and unweighed doses over a week, and the effect on taste consistency. That usually ends the argument, especially when it’s linked to GP targets. - Bar scales should read to 0.1g - Weigh doses and yields when dialling in - Integrated drip-tray scales allow gravimetric shots - Keep spare batteries or charge overnight - Weighing improves both taste and cost control #### Decaf on the espresso bar Decaf on espresso needs the same care as the house blend, yet it is often an afterthought: a hopper of stale beans in an unused grinder. Decaf coffee can behave differently, often more porous and brittle after decaffeination, so it may grind faster, extract more readily and need a coarser grind or a slightly lower temperature. Dial it in properly at the start of the day and record the recipe. Best practice is a dedicated decaf grinder, often a single-dose grinder, so you can weigh beans per shot and keep them fresh. Avoid using the house grinder with decaf, because retained regular coffee contaminates decaf shots, which matters for guests avoiding caffeine for medical or pregnancy reasons. Decaf processes include Swiss Water, sugarcane (ethyl acetate), carbon dioxide and methylene chloride; speciality roasters often favour Swiss Water and sugarcane, and guests increasingly ask. Decaf demand rises in the afternoon and evening; a good decaf can drive afternoon sales. Keep decaf portafilters or baskets marked to avoid mix-ups, and use a clear system for marking decaf cups. Train staff to never guess or substitute; serving caffeine to someone who asked for decaf can genuinely harm them. - Decaf often grinds and extracts differently - Use a dedicated decaf grinder - House grinder retention contaminates decaf - Mark decaf drinks clearly - Never substitute regular coffee for decaf #### Espresso tasting and calibration sessions Calibration means getting everyone on the team to taste and judge espresso the same way. Without it, one barista’s ‘perfect’ is another’s ‘sour’, and the coffee changes shift by shift. A simple weekly session: pull the house espresso at three different grinds (or ratios), label them A, B and C, and have each barista taste and rank them for sweetness, acidity, bitterness and body, then compare notes. Use the same cups, spoons and temperatures. Taste in milk as well, because most sales are milk drinks. Discuss what the roaster intended and agree on target flavour descriptors, then lock the recipe. Rotate who leads so junior staff get confident. Include salt and sugar solution tasting occasionally to calibrate basic tastes, and taste deliberately underextracted and overextracted shots so staff recognise the extremes. Five minutes during a quiet period is enough. The result: fewer arguments about grind, more consistent drinks and staff who can talk to customers about flavour with confidence. Record outcomes in the dial-in log so new staff can see the reference recipe and notes. Invite your roaster to join occasionally; they often appreciate feedback and can help adjust. - Calibration aligns team taste judgements - Taste in milk as well as black - Compare deliberate under- and overextractions - Lock the agreed recipe - Invite roasters to sessions occasionally #### Espresso workflow and station layout The espresso station layout decides how fast and consistent a barista can be. A classic flow: grinder, tamping station and knock box are side by side, so a barista can knock out, wipe, grind, prep and lock in without stepping away. The machine sits next to the prep area, with cups stored on the cup warmer or a shelf within reach. The milk fridge (under-counter) should be next to the steam wand side, with clean jugs and a rinser nearby. Hot water for Americanos and tea, plus syrup and sauce stations, should be at the end of the bar so the milk-steaming barista isn’t interrupted. Pass-out (handoff) points should be clear, away from the ordering queue, so finished drinks don’t clog the till. In two-barista set-ups, one person usually handles shots and the other milk, communicating clearly. Ergonomics matter: counter heights, reach distances and knock box placement affect wrist and shoulder strain over long shifts. If a layout forces staff to cross paths constantly, speed suffers and accidents happen. When designing a new bar, mock it up with tape on the floor and run through a busy morning order sequence with staff before committing to plumbing and electrics. - Keep grinder, tamper and knock box together - Milk fridge should sit near the steam wand - Place hot water and syrups at the bar’s end - Clear handoff points prevent queues - Mock layouts with floor tape before building #### Cold brew production Cold brew steeps coarse coffee in cold or room-temperature water for a long time, often twelve to twenty-four hours, then filters it, producing a smooth, low-acidity concentrate or ready-to-drink coffee. It is different from iced coffee, which is hot coffee chilled or poured over ice. Typical ratios vary widely; concentrates may use one part coffee to four to eight parts water, diluted before serving, while ready-to-drink batches might use one to ten or more. Steep in the fridge for food safety, or at room temperature for a shorter time and then refrigerate promptly; cold brew is a low-acid, water-based drink and can support bacterial growth, so hygiene and refrigeration matter. Filter through paper, cloth or commercial systems such as Toddy or larger brewing bags. Store covered in the fridge and use within a few days; label with dates. Nitro cold brew infuses nitrogen for a creamy, stout-like texture, served from a keg and tap. Cold brew is a high-margin summer product, but production needs fridge space and planning; brew enough for busy days but avoid overproduction. If you bottle and sell cold brew to take away, labelling rules for pre-packed food apply. - Cold brew steeps for roughly 12–24 hours - Cold brew differs from iced coffee - Refrigerate and label with dates - Nitro cold brew uses nitrogen for texture - Bottled cold brew needs proper labelling #### Espresso blends for milk Most UK café coffee is drunk with milk, so the house espresso has to taste good in a flat white, latte or cappuccino. Milk proteins and fats mute acidity, soften bitterness and add sweetness, so a coffee that tastes bright and fruity black may taste sour or thin in milk, while a heavier, chocolatey coffee shines. Blends for milk often use a base of Brazilian or other natural or pulped-natural coffee for body and chocolate, plus a washed Central or South American coffee for sweetness and balance, sometimes with a touch of East African for lift. Plant milks change the picture: oat milk is sweet and full, so a slightly brighter coffee can work; soy can clash with high acidity and curdle in very acidic espresso; almond is thin and nutty. Test your espresso in every milk you sell. Recipes for milk drinks may be shorter (ristretto-style) to keep intensity through larger volumes. Larger takeaway cups dilute flavour; a 12oz latte needs a strong shot to taste of coffee. Some cafés use a different espresso for milk and black drinks, though most keep one house blend for simplicity. Taste with your actual cups and volumes, not just in tiny ceramic cups. - Milk mutes acidity and softens bitterness - Chocolatey blends suit milk drinks - Very acidic espresso can curdle soy milk - Test espresso in every milk you sell - Large cups need stronger shots ### Grinders #### Flat burr and conical burr grinders Commercial espresso grinders use either flat burrs (two parallel discs) or conical burrs (a cone inside a ring). Flat burrs are often associated with clarity and separation of flavours, especially in larger sizes; conical burrs with body, texture and lower retention, and they often run at lower speeds with less heat. In reality, burr geometry, size, speed, alignment and grinder design matter as much as the shape, and both types make excellent espresso. Burr size matters: larger burrs (for example 64mm, 75mm, 83mm or bigger) grind faster, generating less heat per dose, which helps in busy cafés. Burr coatings like titanium can extend life. Speciality ‘high-uniformity’ or ‘SSP-style’ burrs designed for filter-like clarity in espresso exist but may need different recipes and can be less forgiving in milk. When choosing a grinder for a café, think about volume, speed, retention, heat, ease of adjustment, noise, cleaning and service support. Buy the best grinder you can afford before upgrading the machine; a great machine with a poor grinder still makes poor coffee. Ask your roaster or technician which grinders they support, because parts availability and familiar service matter when a grinder fails on a Saturday morning. - Flat burrs are often associated with clarity - Conical burrs often offer lower retention - Larger burrs grind faster with less heat per dose - Grinder quality matters more than machine quality - Choose grinders your technician supports #### Grind-on-demand versus doser grinders Older cafés used doser grinders: coffee was ground into a chamber and swept out by levers, which meant ground coffee sat waiting and staled, and doses were inconsistent. Modern cafés mostly use grind-on-demand (on-demand or ‘doserless’) grinders, which grind directly into the portafilter when triggered, either for a set time (timed dosing) or until a target weight (gravimetric dosing). Timed grinders are cheaper but drift as burrs warm and beans change; baristas weigh doses and adjust time. Gravimetric grinders, with built-in scales, adjust automatically, saving time and reducing waste in busy cafés. Single-dose grinders, where you weigh beans and put them straight into the grinder, have low retention and are great for filter, decaf and guest coffees. Many cafés run two espresso grinders: one for house blend and one for decaf or a single origin. Adding a separate filter grinder avoids changing espresso settings. When budgeting, remember each grinder takes counter space and power. Grind retention, the amount of old coffee left inside, matters; low-retention grinders reduce waste on purging. For decaf on a single-dose grinder, keep a dedicated scale and dose cup next to it so staff aren’t tempted to use the house grinder. - Doser grinders leave ground coffee waiting - Grind-on-demand grinds straight into the portafilter - Timed dosing drifts as burrs warm - Gravimetric grinders dose by weight automatically - Single-dose grinders suit decaf and guest coffees #### Grind retention and purging Grind retention is coffee that stays inside the grinder after grinding, in the chamber, chute and burrs. Retention varies from under a gram to several grams depending on design. Retained coffee is stale by the next shot after a long pause, and after a grind adjustment it is the wrong particle size. That’s why baristas purge, grinding and discarding a small amount, after adjustments, first thing in the morning and after quiet periods. Purging wastes coffee, so it should be measured: grind once, weigh how much comes out compared with expected dose, and decide on a standard purge for your grinder. Some grinders have bellows or blow-out features to clear the chute, and some cafés use a ‘knock’ technique. Static can cause grounds to cling; a few drops of water on beans (the ‘RDT’ or Ross droplet technique) reduces static on single-dose grinders, but avoid it on commercial hopper grinders unless the manufacturer approves. During training, show staff how much coffee they throw away with unnecessary purges; in a busy café that can be a significant cost over a year. Grinder retention also explains why switching beans in a hopper grinder takes several shots to settle. - Retained coffee stales between shots - Purge after grind adjustments and long pauses - Measure standard purge amounts to reduce waste - Bellows help clear grinder chutes - Switching beans takes several shots to clear #### Grind adjustment and drift Grinders adjust by moving burrs closer (finer) or apart (coarser), using stepped settings or stepless collars. Stepless grinders allow tiny changes but are easier to knock out of position; stepped grinders are repeatable but may lack fine control. Adjust while the grinder is running, if the manufacturer recommends it, to avoid beans jamming between burrs when going finer. Grind drifts during the day because burrs heat up (expanding metal and changing grinding behaviour), humidity changes, and beans age. A grinder that ran 28-second shots at 7am might run fast by 9am in a busy café as it warms, or slower when the steam wand and boiler humidity build. Some grinders have cooling fans or large burrs to limit heat. Drift is normal; staff should taste and time regularly and adjust in small steps. Mark the current grind on a strip of tape or record the setting number, and note the time, so the next shift knows. Avoid ‘grinder wars’ where different staff keep adjusting: agree one person responsible during each shift. Burrs wear out over time, gradually causing more fines and harder dial-in; manufacturers give lifespan estimates in kilos ground, and replacement is a routine cost, not a failure. - Stepless grinders allow very fine adjustments - Adjust finer while the grinder runs to avoid jams - Heat and humidity cause grind drift - Record settings for the next shift - Burrs wear out and need replacing #### Burr replacement and grinder servicing Burrs dull with use, producing more fines and less consistent particle sizes, which makes espresso harder to dial in, slows shots and flattens flavour. Manufacturers give approximate lifespans in kilograms of coffee; for espresso burrs this commonly runs to several hundred kilos or more depending on model and coatings, and filter grinders often last longer. A busy café using 15 kilos a week might need new espresso burrs once or twice a year; a quiet café much less often. Signs it’s time: grind settings creeping finer over months, more clumping, inconsistent shots, a gritty texture in the cup, and audible strain. Replacing burrs is straightforward on many grinders but alignment matters; if in doubt, ask your technician. After replacement, new burrs need ‘seasoning’ (breaking in): they may grind differently for the first few kilos, and some cafés run cheap or old coffee through them first. Keep a log of kilos ground, from your roaster invoices, to plan replacements. Servicing also includes cleaning out the chamber, checking the motor, cables and switches, and checking the hopper gate. Budget for burrs as part of annual equipment costs, not as a surprise expense. - Burrs dull and produce more fines - Lifespans are measured in kilos ground - Grind creeping finer suggests worn burrs - New burrs need seasoning - Track kilos ground from roaster invoices #### Grinder cleaning routine Coffee oils and fines build up inside grinders, turning rancid and making coffee taste stale or bitter. A sensible routine: wipe the outside, chute and hopper lid daily; brush out the chute and dosing area at close; empty the hopper into an airtight tub at night; and wash and dry the hopper regularly (weekly in many cafés) with mild detergent, making sure it is fully dry before refilling. Grinder cleaning tablets, made of food-safe grain-based material, can be ground through the burrs to absorb oils, followed by purging some coffee; use only products approved by the grinder manufacturer, never rice, which can damage burrs and motors. Periodically, open the burr chamber to brush and vacuum out old coffee; follow the manufacturer’s instructions and isolate power first. Decaf grinders, sometimes used less often, need extra attention because stale coffee sits longer. Keep a cleaning checklist with dates and initials. In food safety terms, grinders are food-contact equipment, and allergen cross-contamination is usually low risk, but flavoured coffees should never go through the house grinder; flavourings linger and can be noticed by guests. A clean grinder also makes dialling in more predictable and extends burr life. - Coffee oils turn rancid inside grinders - Empty hoppers into airtight tubs at night - Use manufacturer-approved cleaning tablets - Never use rice to clean commercial grinders - Flavoured coffees should never go through the house grinder #### Grinder noise and customer experience Commercial grinders are loud, and in small cafés the noise affects the customer experience and staff hearing over a long shift. Large-burr grinders running at high speed can be particularly noisy. Options include choosing quieter grinders (some models are designed with sound insulation), placing grinders away from seating areas, adding acoustic panels or soft furnishings, and using single-dose or slower conical grinders for filter. In open kitchens and counters, the overall noise of grinders, steam wands, knock boxes and music can build to a level where conversation becomes difficult. UK workplace noise regulations set action levels for daily personal exposure; cafés rarely reach these levels, but busy bars with loud music can come closer than people think, so consider noise when designing the space. For customers, noise affects dwell time and perceived quality; quieter cafés feel calmer and encourage longer stays, which can be good or bad depending on your model. If you rely on fast turnover, a lively sound level may suit you. If you want laptop workers and long brunches, calmer acoustics help. Ask manufacturers for decibel ratings, and listen to machines in a showroom before buying. - Large-burr grinders can be very loud - Acoustic panels reduce noise build-up - Noise affects dwell time and perceived quality - UK workplace noise regulations set exposure action levels - Ask for decibel ratings before buying #### Choosing a commercial grinder When buying a commercial espresso grinder, start with your volume and menu. A café selling 150 coffees a day can use a mid-range on-demand grinder; one selling 500 a day needs a fast, large-burr grinder that doesn’t overheat. Consider: burr size and type; grind speed (seconds per dose); dosing method (timed, gravimetric or single-dose); retention; adjustment system (stepped or stepless, and how easy it is to read); hopper size; cooling; noise; footprint; service support and parts availability; and price. Popular commercial brands in UK cafés include Mahlkönig, Mazzer, Victoria Arduino (Mythos), Anfim, Fiorenzato, Compak, Eureka and Ceado, among others; each has models suited to different volumes. If you offer filter, add a dedicated filter grinder such as a Mahlkönig EK43 style or a shop grinder designed for batch brew. Test grinders with your coffee if possible, as some suit certain roasts better. Factor in burr replacement costs. Don’t forget the grinder for decaf or single origin. A second-hand grinder from a reputable dealer can offer good value. As a rule, prioritise the grinder over the machine: consistency of grind is the foundation of every coffee you sell. - Match grinder speed to your volume - Consider retention and adjustment systems - Check parts and service availability - Add a dedicated filter grinder for batch brew - Prioritise grinder over machine ### Machines #### Espresso machine types Commercial espresso machines come in several types. Heat-exchanger (HX) machines use one large steam boiler with tubes running through it to heat brew water; they’re robust and common but can need cooling flushes for temperature stability. Multi-boiler machines have a separate boiler for steam and for brew water (sometimes one per group), with PID control, offering more stable brewing; they’re common in speciality cafés. Volumetric machines stop shots automatically by flow meter volume; semi-automatics require the barista to stop the shot manually. Gravimetric machines stop shots by weight via built-in scales in the drip tray. Super-automatic or bean-to-cup machines grind, tamp, brew and steam milk at the press of a button, used in hotels, offices, petrol stations and high-volume outlets where trained baristas aren’t available. Lever machines use spring pistons and are rarer in UK cafés. Group count matters: two groups suit small cafés; three suits busy shops; four is for very high volume. Consider power supply (some machines need three-phase), water supply and drainage, space, noise and the service network before buying. A machine’s reliability and support matter more than its look on Instagram, especially when your income depends on it. - Heat-exchanger machines share one boiler - Multi-boiler machines separate brew and steam water - Gravimetric machines stop shots by weight - Bean-to-cup machines suit untrained staff - Some machines need three-phase power #### Buying, leasing or loaning an espresso machine UK cafés typically buy outright, lease through a finance company, or take a machine on loan from a roaster tied to coffee purchases. Buying outright gives freedom to switch roasters and choose the machine, but ties up capital and leaves you responsible for maintenance. Leasing spreads cost over a few years, usually with a fixed monthly fee and sometimes a service package; read the agreement carefully for total cost, early-termination penalties, who owns the machine at the end, and whether it covers grinders. Roaster loans can be generous: a machine and grinder in exchange for buying a minimum amount of coffee each week or month. The catch is lock-in: switching roasters may mean returning equipment, and coffee prices may be higher to cover the loan. Used and refurbished machines are a good budget option if bought from reputable dealers with warranties; avoid unknown private sales unless a technician inspects the machine. Factor in installation (water, drainage, electrics), a water filter, a knock box, a milk fridge, jugs, scales and spare parts. For new businesses, a roaster loan can lower start-up costs, but model the long-term coffee cost carefully against buying your own kit. - Buying gives freedom but ties up capital - Leasing spreads cost over a fixed term - Roaster loans usually require minimum coffee orders - Check early termination terms carefully - Refurbished machines need reputable dealers #### Machine installation essentials Installing an espresso machine is more than plugging it in. It needs an appropriate electrical supply (many two- and three-group machines need a dedicated high-amperage circuit, and some need three-phase), installed by a qualified electrician. It needs a mains water supply with an isolation valve, a non-return valve to protect the mains (water supply regulations require backflow protection), and a water filter matched to your local water. It needs a drain with suitable falls and access; machines discharge hot water and coffee grounds that can block drains, so many cafés fit grease or silt traps. Space matters: room for the machine, grinders, knock box, cup warmer, milk fridge, and clearance for ventilation and servicing. Counter strength matters, because a three-group machine is heavy. Consider workflow and ergonomics: counter height, where the barista stands, and where customers wait. A technician usually installs and commissions the machine, setting temperatures, pressures, flow rates and volumetrics. Keep the installation documentation for insurance and future engineers. Plan for future upgrades by allowing spare power and plumbing capacity. If you’re in a rented unit, check lease terms and get landlord consent for plumbing and electrical alterations before work begins. - Many machines need a dedicated circuit - Backflow protection is required on water supply - Fit a water filter matched to local water - Drainage must handle hot water and grounds - Get landlord consent for alterations #### Steam wands and steam pressure Steam wands deliver steam from the boiler to texture milk. Steam pressure is commonly somewhere around 1 to 1.5 bar on many commercial machines, though it varies by machine and setting. Steam tips have different numbers and sizes of holes: more or larger holes deliver more power and faster steaming, suiting large jugs and busy cafés, while fewer holes give more control for small jugs and training. Many cafés swap tips to match their volume. Cool-touch wands with insulated walls reduce milk burning onto the wand and make cleaning easier. Automatic steam wands, with temperature probes that stop steaming at a set temperature, or fully automatic milk systems, help consistency in high-volume outlets. Keep wands clean: purge before and after every use, wipe immediately with a dedicated damp cloth, and soak tips in milk-system cleaner regularly to clear blockages. Blocked holes cause uneven texturing and screeching. Low steam power can mean scale, a blocked tip, a failing element, or an undersized machine for the volume. Ensure steam valves don’t leak; a dripping wand wastes energy and water. Never leave a milk jug sitting under a wand, which can draw milk back into the boiler when the wand is opened or cooled. - Steam pressure is commonly around 1–1.5 bar - More tip holes give faster steaming - Cool-touch wands reduce burnt-on milk - Purge and wipe wands after every use - Milk can be drawn back into a boiler #### Hot water taps and Americano workflow The machine’s hot water tap draws water from the steam boiler, often very hot, and may mix in cold water to reduce temperature. It’s used for Americanos, long blacks, tea and rinsing. In high-volume cafés, a separate hot water boiler or font for tea and Americanos reduces load on the espresso machine and keeps steam pressure strong for milk. Americanos: espresso topped with hot water, usually in a larger cup. Long blacks, popular in Australian and New Zealand-style cafés, put hot water in the cup first and espresso on top, preserving more crema. Train staff on volumes: too much water makes a thin Americano, while too little makes it intense; many cafés pour to a set line on the cup and offer cold milk on the side. Water temperature matters: very hot water from the steam boiler can scald coffee and guests, so some machines let you adjust tap temperature. For tea, boiling water is right for black tea but too hot for green and white teas; a separate variable-temperature boiler helps if you serve speciality tea. Clean the hot water nozzle as scale and debris can accumulate. Record hot water volumes in recipes to ensure consistency and cost control. - Machine hot water usually comes from the steam boiler - Separate boilers reduce load on the espresso machine - Long blacks put espresso on top of water - Set Americano volumes in recipes - Green tea needs cooler water than black tea #### Bean-to-cup machines in hospitality Bean-to-cup machines automate grinding, dosing, tamping, brewing and milk frothing, producing espresso-based drinks at the touch of a button. They suit hotels, offices, event venues, pubs, petrol stations and places where staff turnover is high or volume is unpredictable. Commercial models from brands such as Franke, Schaerer, WMF, Jura and Eversys vary hugely in capacity and quality; top models can produce excellent, consistent drinks, while cheaper units can make bitter coffee with foamy, overheated milk. Key considerations: daily cup capacity, milk system (fresh milk systems need refrigeration and rigorous cleaning), number of milk types, menu programming, telemetry, and service contracts. Daily cleaning is essential, especially automated milk system cleaning, which is critical for food safety; poorly cleaned milk lines harbour bacteria. Costs include purchase or lease, service contracts, cleaning products and filters. Bean choice still matters: use a coffee suited to the machine’s grinder and settings, and ask your roaster or supplier to programme recipes. For pubs and hotels where coffee is a side line, bean-to-cup can be a good return; for speciality cafés where the craft is the attraction, it can undermine the experience, though some high-end automated machines are used in speciality settings. - Bean-to-cup automates the whole espresso process - Suits venues with untrained or changing staff - Milk systems need rigorous daily cleaning - Service contracts are important - Quality varies widely by model #### Espresso machine energy use Espresso machines use significant energy because boilers stay hot all day. A two- or three-group machine on all day, every day, can be one of a café’s biggest single electricity users after refrigeration and ovens. Energy-saving options include: machines with insulated boilers, eco modes or scheduled on/off timers; turning off unused groups or boilers during quiet periods if the machine allows; turning off cup warmers when not needed; and ensuring the machine isn’t left on overnight unless the manufacturer recommends it. Some newer machines heat water on demand or use smaller, independently controlled boilers. Scale build-up increases energy use, so filtration helps. Steam wands left dripping waste energy, as do frequent unnecessary flushes. When choosing a new machine, ask for energy consumption data in standby and in use. Smart meters or plug monitoring (for single-phase equipment) help you understand usage. Pair machine timers with your opening routine so it’s hot by the time the first barista dials in. Saving energy also protects equipment from heat stress. Discuss with your technician before changing settings, because turning boilers on and off frequently can stress components and some machines are designed to stay hot. - Espresso machines are major electricity users - Use timers and eco modes - Turn off unused cup warmers - Scale increases energy use - Ask technicians before changing heat settings #### Coffee for drive-throughs and kiosks Drive-throughs, kiosks, train-station units and stadium stands need coffee that’s fast, consistent and simple to train. Many use high-end bean-to-cup machines or semi-automated machines with automatic milk steaming and gravimetric dosing, so new staff can produce consistent drinks in seconds. Menus are usually tight: a handful of core drinks, one or two milk alternatives, a few syrups and seasonal specials. Workflow is designed around throughput: pre-steamed milk is not acceptable for quality, so automatic wands and multiple milk jugs keep pace. Cups and lids are standardised to reduce choices. Kiosks face power and water challenges; some use plumbed-in water tanks and pumps, or require a dedicated electricity supply. Outdoor units need weather protection. Food safety still applies: milk temperature control, cleaning, hand washing facilities and allergen information. Licensing may include street trading consent for mobile units, depending on the local authority. Card and contactless payments dominate. Think about queues: a kiosk that sells 300 coffees a morning needs one person taking orders and two on the machine. Speed-of-service targets, measured from order to handoff, help train staff and plan staffing. - Automated milk steaming helps speed - Keep kiosk menus tight - Power and water supply are key constraints - Street trading consent may be needed - Measure speed from order to handoff ### Water #### Water for coffee Coffee is mostly water, and water chemistry affects both taste and equipment. The SCA publishes water quality guidelines with target ranges for total dissolved solids, hardness and alkalinity; in simple terms, water should be clean, odour-free, moderately mineralised and not too hard or too soft. Hardness (mostly calcium and magnesium) helps extraction but causes limescale; alkalinity (mostly bicarbonate) buffers acidity, so high alkalinity makes coffee taste flat and chalky, while very low alkalinity makes it sharp. Much of south and east England, including London, has hard water, which means scale risk is high and filtration is essential. Scotland, Wales and northern England often have softer water. Very soft water can be corrosive to boilers and taste flat. Filtration options include carbon filters (removing chlorine and taste), ion-exchange cartridges (reducing carbonate hardness), and reverse osmosis with remineralisation for precise control. Your water supplier publishes hardness data by postcode, and filter manufacturers will test water and recommend settings. Change filters on schedule; a spent filter offers no protection. Scale damage is a common cause of costly repairs and voided warranties, so water treatment is a core equipment expense, not an extra. - Water chemistry affects taste and scale - High alkalinity makes coffee taste flat - Much of south and east England has hard water - Water suppliers publish hardness by postcode - Spent filters give no protection against scale #### Reverse osmosis and water recipes Reverse osmosis (RO) pushes water through a fine membrane, removing most dissolved minerals. Pure RO water is too empty for good coffee and can be aggressive to metal, so commercial RO systems for cafés usually remineralise or blend RO water with filtered mains water to hit a target mineral content. This gives consistency regardless of local water, useful in hard-water areas or for chains wanting identical coffee across sites. RO systems cost more upfront, need space, and waste some water as concentrate (the amount depends on the system), so consider the environmental and running costs. Some speciality cafés build ‘water recipes’ by adding precise amounts of minerals to distilled or RO water, especially for filter, but this is more common at competitions and in roasteries than in everyday service. For most cafés, a good ion-exchange or blending filter correctly set by a technician is enough. If you serve filter as a speciality, testing water with a TDS meter and a simple hardness and alkalinity kit helps. Remember that tea is also sensitive to water; hard water creates scum on black tea and dulls green tea, so a well-filtered water supply benefits the whole menu. - RO removes most dissolved minerals - Pure RO water is unsuitable for coffee - Commercial RO systems remineralise water - RO systems produce waste concentrate - Hard water causes scum on black tea #### Descaling and scale damage Limescale builds up when hard water is heated, coating heating elements, boilers, valves and pipes. It reduces heating efficiency, blocks small passages (gicleurs, flow restrictors, solenoid valves), causes temperature instability and leads to element failure. Symptoms include slower shots, inconsistent flow between groups, weak steam, noisy boilers and a crusty build-up visible on the steam wand or shower screen. Prevention is far better than cure: correctly sized water filtration changed on time. Descaling a commercial machine is a technician’s job on most models; it involves dismantling and chemical treatment, and doing it wrongly can damage components or leave chemicals in the system. Many machine warranties exclude scale damage if no filter was fitted or maintained, so keep receipts and filter change records. Bean-to-cup machines often have automatic descaling programmes; follow the manufacturer’s schedule and use approved products. Kettles and hot-water boilers used for tea also scale up and should be descaled regularly with suitable products, then flushed thoroughly. Scale costs can be surprising: a single boiler repair can wipe out years of filter savings. If you see regular scale despite filtration, ask for a water test and filter recalibration. - Scale damages elements, valves and boilers - Weak steam can signal scale build-up - Commercial descaling is usually a technician job - Warranties may exclude scale damage - Keep filter change records ### Maintenance #### Daily machine cleaning: backflushing Daily cleaning keeps espresso tasting clean and protects the machine. During service, baristas flush group heads between shots and wipe portafilters. At close, the standard routine is backflushing: insert a blind basket (no holes) into the portafilter, add the recommended amount of espresso machine detergent (such as Cafiza, Puly Caff or similar), lock it into the group and run cycles of on and off, forcing water and detergent back through the group head and solenoid valve to dissolve oils. Then rinse with several cycles of clean water. Many machines have automatic cleaning programmes. Soak portafilters and baskets (without handles in the solution if the manufacturer advises) in hot detergent solution, scrub, and rinse thoroughly. Brush around the group gasket and shower screen with a group brush. Remove and clean shower screens regularly (often weekly). Clean drip trays, empty the drain box and flush the drain with hot water. Note that lever machines and some designs shouldn’t be backflushed with detergent; follow the manufacturer’s guidance. Leaving oils overnight gives tomorrow’s first shots a rancid taste. Use a checklist to make cleaning consistent, and keep chemicals stored and labelled under COSHH requirements. - Backflush with a blind basket and detergent - Rinse thoroughly after detergent cycles - Soak portafilters and baskets - Remove shower screens regularly - Store cleaning chemicals under COSHH rules #### Group head gaskets and shower screens The group gasket is the rubber seal that the portafilter locks against; the shower screen is the mesh plate that spreads water over the puck. Both are wear parts. Gaskets harden with heat over time, causing portafilters to lock further to the right, leaks around the group during shots, and inconsistent pressure. Replace gaskets periodically, often once or twice a year in busy cafés, or when they become hard or crack. Shower screens collect coffee oils and fines; a dirty screen spreads water unevenly and adds bitter, stale flavours. Remove screens (usually by unscrewing a central screw) and soak them in detergent weekly, scrubbing the dispersion block behind. Replace damaged screens. Precision shower screens can improve water distribution. Always keep a small stock of gaskets, screens, screws and spare basket springs; ordering them when one breaks on a Saturday is painful. Some cafés replace all gaskets at the same time to keep groups consistent. When a technician services the machine, ask them to show staff how to change a gasket safely. Make sure the machine is cool and pressure is released before doing any work on group heads, as hot water and steam can scald. - Gaskets harden and need regular replacement - Leaks around the group suggest a worn gasket - Clean shower screens weekly - Keep spare gaskets and screens - Work on group heads only when safe and cool #### Planned preventive maintenance Espresso machines and grinders are workhorses, and breakdowns cost sales. Planned preventive maintenance (PPM) means having a technician service equipment on a schedule, often every six or twelve months depending on volume, rather than waiting for failure. A typical service includes changing gaskets and shower screens, checking pressures and temperatures, inspecting the boiler, safety valves, elements, pumps, solenoid valves and steam valves, checking for scale and leaks, and recalibrating volumetrics. Pressure vessels such as espresso machine boilers may fall under the Pressure Systems Safety Regulations, which can require a written scheme of examination and periodic inspections by a competent person; your technician or insurer can advise on what applies to your machine. Keep service records and certificates. Service contracts with response times are worth considering for busy cafés; compare call-out fees and hourly rates with contract prices. Make sure your technician carries common spares. Train staff to recognise early warning signs: unusual noises, pressure gauge readings outside normal ranges, leaks, or steam wands losing power. Report issues early. Combining PPM with good water filtration and daily cleaning significantly reduces major failures and helps preserve the machine’s resale value. - Service machines every six to twelve months - Pressure vessels may need written schemes of examination - Keep service records and certificates - Service contracts can include guaranteed response times - Train staff to spot early warning signs #### Knock boxes and coffee grounds Every espresso shot leaves a spent puck, and a busy café produces kilos of wet grounds a day. Knock boxes collect them; under-counter knock chutes drop grounds straight into a bin below the counter, keeping the bar clear. Empty knock boxes frequently, because full, wet grounds smell, attract flies and get heavy enough to cause back strain. Never knock pucks into the sink; grounds block drains and can damage grease traps. Spent grounds are commercial waste in the UK: under current rules, businesses must present food waste separately for collection under the simpler recycling requirements in England, introduced for businesses from 2025 (with micro-firms given more time), and similar food-waste rules already apply in Scotland and Wales. Coffee grounds can go in food waste collections, or be collected by specialist recyclers who turn them into fuel products or other materials. Many cafés also give grounds away to customers for gardens; that’s fine if you’re happy with it, though grounds aren’t a miracle fertiliser and should be composted, not dumped straight on beds in large amounts. Check your waste contracts to make sure grounds are being handled correctly, and keep waste transfer notes as required. - Under-counter knock chutes keep bars clear - Never knock grounds into sinks - Business food waste must be separated under current rules - Specialist recyclers collect coffee grounds - Keep waste transfer notes #### Espresso machine safety Espresso machines combine pressurised boilers, steam, hot water and electricity, so safety training matters. Common injuries are scalds from steam wands, hot water taps and group heads, and burns from portafilters and hot surfaces. Train staff to purge steam wands away from themselves and others, keep hands clear of groups when flushing, and never remove a portafilter mid-shot, which can spray hot water and grounds. Pressure relief valves protect boilers; if one hisses or discharges, report it immediately. Pressure gauges should be checked daily for readings outside normal ranges. Electrical safety: keep water away from plugs and sockets, report frayed cables, and have equipment inspected as part of your electrical maintenance programme. Lifting: espresso machines are heavy, so moving them is a job for technicians with proper equipment. Chemicals: espresso machine detergents and descalers are hazardous substances under COSHH; store them correctly, use gloves where recommended, and keep safety data sheets accessible. Include machine safety in staff induction and risk assessments, and record training. First aid kits should include burn dressings, and staff should know to cool burns under cool running water for an extended period, typically around twenty minutes, before seeking further help. - Steam and hot water are main scald risks - Never remove a portafilter mid-shot - Report discharging pressure relief valves immediately - Detergents and descalers fall under COSHH - Cool burns under running water for around 20 minutes ### Milk Drinks #### Flat white The flat white came to the UK from Australia and New Zealand, where both countries claim it, and became the signature drink of the London speciality wave in the late 2000s before chains adopted it. In speciality cafés it is a small drink, often around 5 to 6 ounces (roughly 150 to 180 millilitres), built on a double shot or ristretto-style double, with thin, glossy, velvety milk and only a very fine layer of microfoam, so the coffee flavour stays prominent. It is typically served in a ceramic cup with a latte art pattern on top. In chains, flat whites can be larger and closer to a strong latte, which confuses guests moving between shops. Define your flat white clearly in your recipe book: cup size, shot recipe, milk depth, temperature. Many cafés steam milk for flat whites slightly cooler, around 55 to 60°C, for sweetness and drinkability. The upsell is natural: guests who want ‘a stronger latte’ are often happiest with a flat white. When someone asks the difference, a fair one-liner is: ‘smaller than a latte, with less milk and thinner foam, so it tastes more of coffee.’ Price it close to a latte; the coffee cost is the same, milk cost lower. - Australia and New Zealand both claim the flat white - Speciality flat whites are around 5–6oz - Thin microfoam keeps coffee flavour prominent - Chain flat whites are often larger - Define cup, shot, milk depth and temperature in recipes #### Cappuccino The cappuccino is an Italian classic: espresso with steamed milk and a thicker layer of foam. In Italy it’s usually small, around 150 to 180 millilitres, and drunk in the morning. In the UK, cappuccinos come in every size, from a speciality café’s 6oz cup with a centimetre or so of silky foam to a large chain cup with a dome of stiff froth and a chocolate dusting. Guests have strong expectations: many British customers expect cocoa or chocolate powder on top, while speciality cafés may not dust unless asked. Ask, or make it a standard option. The key quality issue is foam texture: it should still be fine microfoam, just more of it, not big, dry bubbles that sit on top like soap suds. Stretch milk for longer during steaming to incorporate more air, then swirl to integrate. A ‘dry’ cappuccino has more foam and less milk; a ‘wet’ one is closer to a latte. Some guests order ‘extra hot’; respect it, but cap at a safe temperature (often around 70°C) and warn that very hot milk loses sweetness. For takeaway, cappuccino foam can stick to the lid; leave a little space, or offer it in a wider cup. - Italian cappuccinos are small, morning drinks - Many UK guests expect a chocolate dusting - Cappuccino foam should still be microfoam - ‘Dry’ means more foam, ‘wet’ means more milk - Cap ‘extra hot’ milk at a safe temperature #### Cortado and piccolo Cortado comes from Spain, where it means ‘cut’: espresso cut with a small amount of warm milk, roughly equal parts, usually served in a small glass. In UK speciality cafés, a cortado is commonly a double shot with a similar volume of steamed milk and little foam, in a 4 to 4.5oz glass or cup. The piccolo latte, an Australian invention, is a ristretto shot topped with steamed milk in a small glass, usually around 90 to 100 millilitres; think of it as a tiny latte. Definitions overlap heavily, and many cafés serve near-identical drinks under both names. Pick a recipe and stick to it. These small, strong drinks are popular with regulars, baristas and guests who want coffee flavour without a big milk drink. They’re also efficient to make, with less milk to steam. Price them sensibly: they use the same coffee as a flat white but less milk, so many cafés price slightly below a flat white. Steaming a tiny amount of milk is tricky; use a small jug (around 300 to 350ml) and steam just enough, or share a jug with another drink. A cortado’s glassware is part of the appeal, but glasses must be heat-resistant and handled carefully when hot. - Cortado means ‘cut’ in Spanish - Cortados use roughly equal espresso and milk - The piccolo latte is an Australian invention - Definitions vary between cafés - Use small jugs for small drinks #### Macchiato and its confusions A traditional macchiato (Italian for ‘stained’ or ‘marked’) is a single or double espresso topped with a small spoonful of milk foam or a dash of steamed milk, served in an espresso cup. A ‘latte macchiato’ is the reverse: a glass of steamed milk ‘stained’ with espresso poured on top, creating layers. Large chains popularised a caramel macchiato, which is a vanilla latte with espresso on top and caramel drizzle, nothing like the Italian original. This causes confusion at the counter: a guest asking for a macchiato may expect a tiny espresso or a large sweet layered drink. Train staff to clarify politely: ‘Our macchiato is espresso with a little foam on top. Would you like that, or something larger and sweeter?’ Never make a guest feel silly. Some cafés offer a ‘long macchiato’, an Australian-style drink of a double espresso, or espresso over water, topped with a little milk. If you have room on the menu, listing a short description under each drink reduces confusion. For speed, macchiatos are quick to make if you have milk already steamed for other drinks, but don’t use old, separated foam; it should still be fresh and silky. - Macchiato means ‘stained’ or ‘marked’ - A latte macchiato is milk stained with espresso - Chain caramel macchiatos differ from the original - Clarify what guests expect politely - Short menu descriptions reduce confusion #### Mocha A mocha is espresso, chocolate and steamed milk, often topped with foam, cocoa, whipped cream or chocolate shavings. Quality varies enormously: a mocha made with cheap sweetened cocoa powder tastes thin and sugary; one made with good chocolate (melted chocolate, a quality chocolate sauce, or a high-cocoa drinking chocolate) tastes rich and balanced. The method matters: mix chocolate powder or sauce with the espresso in the cup first to dissolve it fully before adding milk, or steam chocolate and milk together in the jug if your powder suits it, cleaning the wand immediately. Taste-test ratios: too much chocolate overwhelms the coffee; too little makes it a sweet latte. Mochas are popular with younger guests, as a treat, and in colder months. They’re a good margin drink because you can charge a premium for chocolate, though good chocolate is not cheap; calculate cost per serving. Allergens matter: chocolate products may contain milk (even dark chocolate), soy lecithin and may be produced alongside nuts, so check labels and include them in your allergen matrix. For plant-based guests, choose a dairy-free chocolate; many chocolate powders contain milk solids. A ‘white mocha’ uses white chocolate, which always contains milk. - Mocha is espresso, chocolate and steamed milk - Dissolve chocolate in espresso first - Many chocolate powders contain milk - Calculate chocolate cost per serving - White chocolate always contains milk #### Babyccinos and children’s drinks A babyccino is warm frothed milk, often topped with cocoa or a marshmallow, served in a small cup for children. It’s an Australian café tradition that’s spread to the UK. Serve it at a lower temperature than adult drinks, perhaps around 40 to 50°C, and tell parents it’s not hot. Some cafés offer it free with an adult drink; others charge a small amount. Children’s hot chocolates and steamers (steamed milk with syrup) are also popular. Check allergens carefully: marshmallows may contain gelatine and allergens; cocoa may contain milk and may be produced alongside nuts. Avoid serving caffeinated drinks to young children unless parents specifically ask; many cafés have a policy of not serving coffee to children, which is a business choice rather than a legal requirement. Use sturdy cups or cups with handles, and avoid glass. Children’s drinks help make cafés family-friendly, increasing visits from parents during the day. However, family-friendly cafés need space for prams, highchairs, baby-changing facilities and patience from staff. Consider a small kids’ menu with snacks and drinks, and price it to cover costs while encouraging family visits. - A babyccino is warm frothed milk for children - Serve children’s drinks at around 40–50°C - Marshmallows may contain gelatine and allergens - Refusing coffee to children is a business choice - Family-friendly cafés need space and facilities #### Coffee tonic and espresso soda drinks Coffee tonic, espresso poured over tonic water and ice, has become a summer favourite in speciality cafés, often garnished with citrus. It tastes bright, bitter and refreshing. Build it in a tall glass: ice, tonic, then pour espresso slowly on top to create a layered look and avoid excessive fizzing. Fruity, lighter-roast espressos or cold brew concentrate often work best; dark roasts can taste harsh. Variations include espresso with ginger beer, lemonade, sparkling water, or orange juice (the ‘espresso orange’). Some cafés add cascara, bitters or flavoured syrups. These drinks require ice, fridge space for mixers and good glassware or clear plastic cups for takeaway. They’re quick to make and command a premium price, typically more than a standard iced latte, and look great on social media. Check that mixers don’t contain allergens or high caffeine, and be aware of the Soft Drinks Industry Levy on high-sugar mixers, which affects pricing from suppliers. Offer non-alcoholic versions of espresso cocktails as alternatives during the day. Train staff on recipes and pouring technique; espresso poured too fast into tonic can foam over, wasting product and making a mess. - Coffee tonic is espresso over tonic and ice - Pour espresso slowly to reduce fizzing - Fruity, lighter espressos often work best - Ice and fridge space are essential - High-sugar mixers carry the Soft Drinks Industry Levy #### Affogato and coffee desserts An affogato (Italian for ‘drowned’) is a scoop of vanilla ice cream or gelato with a shot of hot espresso poured over it at the table or just before serving. It’s a simple, high-margin dessert for cafés and restaurants. Use good ice cream or gelato and a freshly pulled shot; some places offer a liqueur, such as amaretto or Frangelico, for an alcoholic version, which requires an alcohol licence. Variations include chocolate, hazelnut or salted caramel ice cream, plant-based ice cream for vegan guests, and toppings such as biscotti or cocoa nibs. Other coffee desserts include tiramisu, coffee cake, coffee panna cotta, and coffee granita. When serving, pour espresso tableside for theatre, or serve the shot separately so guests can pour it themselves. Check allergens in ice cream (milk, egg, sometimes nuts) and toppings. For takeaway, affogato is tricky because the ice cream melts quickly; most cafés offer it sit-in only. Price it well above the cost of a scoop and a shot; it’s one of the easiest ways to increase average spend in an afternoon. Store ice cream at correct temperatures and use clean scoops to avoid cross-contamination. - Affogato means ‘drowned’ in Italian - Espresso is poured over vanilla ice cream - Alcoholic versions need an alcohol licence - Serve the shot separately for theatre - Check allergens in ice cream and toppings #### Steamers and caffeine-free milk drinks Not every guest wants coffee or tea; caffeine-free milk drinks fill that gap. Steamers (sometimes called babyccinos for adults, or vanilla milks) are steamed milk flavoured with syrup, such as vanilla or caramel. Golden lattes (turmeric lattes) blend turmeric, ginger, cinnamon and black pepper with milk; they’re often made from a powder or paste mixed with milk and steamed. Beetroot lattes and other coloured lattes (like blue spirulina) appeared during the wellness trend, adding colour for social media. Chai can be caffeinated (with black tea) or caffeine-free (rooibos chai). Matcha contains caffeine, so it doesn’t count as caffeine-free. For these drinks, use the same milk texturing skills as for coffee; powders can clump, so whisk with a little hot water or milk first. Clean steam wands carefully, as turmeric stains and beetroot colours linger. Avoid making health claims; in the UK, nutrition and health claims on food are regulated, and claiming that turmeric ‘reduces inflammation’ on a menu could breach the rules. Price them similarly to lattes. They’re useful for pregnant guests, children (with care), and evening customers who want something warm without caffeine. - Steamers are flavoured steamed milk - Golden lattes use turmeric and spices - Matcha contains caffeine - Whisk powders before steaming - Health claims on food are regulated in the UK ### Milk #### Milk science for baristas Milk is mostly water, with fats, proteins (casein and whey), lactose sugar and minerals. When you steam milk, injected air creates bubbles, and proteins coat them to stabilise foam; fats contribute creaminess and flavour but can make foam less stable. Heating breaks down some proteins and increases perceived sweetness up to a point; around 55 to 65°C, milk tastes sweetest. Beyond around 70°C, proteins denature further, foam starts to collapse, and milk can develop a cooked, sulphurous flavour. That’s why ‘extra hot’ drinks often taste flat. Whole milk (around 3.5 to 4 per cent fat in the UK) gives creamy texture and balanced foam; semi-skimmed (around 1.5 to 1.8 per cent) foams easily but tastes thinner; skimmed foams stiffly with large bubbles but tastes watery. Fresh milk foams better than older milk near its use-by date; age and temperature affect proteins. Cold milk gives you more time to texture, so keep milk in the fridge until use and start steaming at fridge temperature. Avoid re-steaming milk: reheated milk loses texture and sweetness and wastes quality. Barista training benefits from tasting milk at different temperatures to show the sweetness peak, and from understanding why plant milks behave differently. - Milk sweetness peaks around 55–65°C - Above around 70°C foam collapses and tastes cooked - Whole milk gives balanced texture - Cold milk allows more texturing time - Never re-steam milk #### Milk temperature and thermometers Most speciality cafés steam milk to roughly 55 to 65°C, with many targeting around 60°C. Guests ordering ‘extra hot’ often get around 70°C; ‘warm’ or children’s drinks may be around 40 to 50°C. Experienced baristas judge temperature by touch, holding the jug and noting when it becomes too hot to hold comfortably, and by sound. Thermometers clipped to jugs help training and consistency, though they lag behind actual temperature, so baristas should stop a little before target. Temperature-sensing steam wands that stop automatically help consistency in busy cafés. For children’s drinks (babyccinos, warm milk), keep temperature lower to avoid scalds, and make clear it’s not as hot as adult drinks. Takeaway drinks lose heat in cups, so some guests ask for hotter drinks; consider lids, sleeves and double-walled cups rather than overheating milk. Very hot drinks are a scald risk, particularly for children and in cars. There have been well-known court cases internationally about scalding drinks; in the UK, the key is reasonable temperature, safe lids and clear handling. Record target temperatures in recipes and train staff to stick to them, then cool slightly for children or vulnerable guests on request. - Speciality cafés commonly steam to around 60°C - Extra hot is usually around 70°C - Clip thermometers lag behind actual temperature - Children’s drinks should be cooler - Use lids and sleeves rather than overheating milk #### Milk jug technique and sizing Milk jugs (pitchers) come in sizes from around 300ml to 1 litre. Choose the jug to match the drink: a small jug for cortados and flat whites, medium for lattes and cappuccinos, and large for sharing milk across two or three drinks. Fill the jug to just below the spout’s base, roughly a third to half full, leaving room for milk to expand as it aerates. Too much milk in a large jug wastes milk; too little doesn’t create a proper vortex. Many cafés mark fill lines inside jugs with etched lines or use jugs with internal measuring marks. Measuring milk reduces waste dramatically: a café that throws away a few centimetres from every jug can waste litres a day. Technique: purge the wand, place the tip just below the surface, open the steam fully, stretch (introduce air) briefly with a gentle tearing sound, then lower the tip to create a whirlpool that breaks large bubbles and heats the milk evenly. Stop at target temperature, wipe and purge the wand, tap and swirl the jug to polish the milk, then pour immediately. Spouts matter for latte art: sharper spouts give finer detail, rounder spouts suit beginners and larger patterns. - Fill jugs to just below the spout base - Match jug size to drink size - Fill lines reduce milk waste - Stretch briefly, then create a whirlpool - Sharp spouts give finer latte art detail #### Reducing milk waste Milk is one of a café’s largest variable costs, and waste is common: over-filled jugs, milk left in jugs between drinks, milk going out of date, and re-steamed or discarded milk. Practical fixes: measure milk for each drink using fill lines, or pour from a measured carafe; teach staff to steam exactly what’s needed; use smaller jugs for single drinks and larger jugs for batches; pour leftover cold milk back into the fridge immediately rather than letting it warm; keep a ‘waste milk’ log for one week to show staff how much goes down the drain. Order milk based on usage data, rotate stock (first in, first out), and store it in the coldest part of the fridge. Check plant milks’ opened shelf life, often a few days once opened. Some cafés use bag-in-box or bulk milk systems for efficiency and less packaging waste. Steamed milk that hasn’t been used shouldn’t be re-steamed for another drink, as quality suffers; better to avoid the waste in the first place. The savings add up: even a modest reduction in waste per drink across hundreds of drinks a day can save hundreds or thousands of pounds a year. Share the numbers with staff to motivate them. - Milk is a major variable cost - Fill lines and measured carafes cut waste - Log waste milk for a week to show the scale - Plant milks have short opened shelf lives - Unused steamed milk shouldn’t be re-steamed #### Barista editions of plant milks Plant milks for coffee are often sold as ‘barista’ editions, formulated with added oils, acidity regulators (such as dipotassium phosphate), stabilisers and sometimes sugars to foam better and resist curdling in hot, acidic coffee. Oat milk dominates UK cafés, thanks to its natural sweetness, creamy texture and good foaming, with brands like Oatly, Minor Figures, Alpro and Califia common. Soy milk foams well but can split in acidic espresso and has a distinct beany taste. Almond milk is thinner and nutty and can separate. Coconut milk drinks vary widely in texture. Pea, hazelnut, cashew and blends appear too. Each behaves differently: oat milks often need less stretching and slightly lower temperatures; soy can scorch easily; almond creates big bubbles. Test each with your espresso and train staff on the differences. Allergen labelling matters: almond, hazelnut and cashew are tree nuts; soy is a regulated allergen; oat milk may contain gluten unless certified gluten-free. Use separate, clearly marked jugs for each plant milk if allergen-sensitive guests are common, and always wash jugs and purge wands thoroughly. Many UK cafés no longer charge extra for plant milk, but some still do; decide your policy based on cost and customer expectations. - Barista plant milks contain stabilisers and oils - Oat milk dominates UK cafés - Soy milk can split in acidic espresso - Nut milks are tree-nut allergens - Oat milk may contain gluten unless certified #### Milk allergy versus lactose intolerance Milk allergy and lactose intolerance are different, and confusing them is dangerous. A cows’ milk allergy is an immune reaction to milk proteins and can cause hives, vomiting, breathing difficulties and, rarely, anaphylaxis; even traces can matter. Milk is one of the fourteen allergens that UK food businesses must declare under food information law. Lactose intolerance is a digestive issue where the body doesn’t break down lactose sugar well, causing bloating and discomfort, but it isn’t life-threatening; lactose-free milk (dairy milk with lactase enzyme added) suits lactose-intolerant guests but is still dairy, so it’s unsuitable for anyone with milk allergy. When a guest asks for non-dairy milk, ask if it’s an allergy. If it is, follow your allergy procedure: use a clean jug, purge and wipe the steam wand thoroughly (or use a dedicated wand), avoid shared spoons, and check syrups, sauces, toppings and chocolate for milk. Be honest about cross-contact risks in a busy bar; you may not be able to guarantee no trace. Many cafés use colour-coded jugs for plant milks. Record and communicate allergens clearly on orders and cups. Staff training should include reading labels for hidden milk, such as whey, casein and lactose in ingredients. - Milk allergy is an immune reaction to milk proteins - Lactose intolerance is digestive, not allergic - Lactose-free milk is still dairy - Milk is one of the 14 declarable allergens - Use clean jugs and purged wands for allergy orders #### Dairy supply and milk choice Milk choice affects taste, cost and your story. Most UK cafés buy from wholesalers or dairy distributors; some partner with local dairies offering organic or single-herd milk with higher fat or different breeds such as Jersey or Guernsey, which can taste richer. Homogenised, pasteurised whole milk is standard; unhomogenised milk can separate and foam less consistently. Barista-specific dairy milks are also sold, standardised for consistent foaming through seasonal variations in fat and protein; cows’ diets change between grass and winter feed, affecting milk composition and steaming. Milk prices fluctuate with farmgate prices, feed and energy costs; track supplier price changes and recalculate drink costs. Delivery frequency matters: daily or alternate-day deliveries keep milk fresh. Glass bottles from local dairies are charming but impractical at volume; larger plastic containers or bag-in-box reduce handling. Consider sustainability claims carefully, especially ‘local’ and ‘organic’, which must be accurate. Organic milk must come from certified organic sources, and you shouldn’t describe drinks as organic unless certification covers the claim. Plant milks come in cartons; recycling options vary by local authority. Taste-test a few milks with your espresso before deciding, because milk is half of most drinks you sell. - Jersey and Guernsey milk taste richer - Barista dairy milks are standardised for foaming - Milk composition changes with season - Track milk price changes - Organic claims require certified sources ### Filter Methods #### V60 pour-over The Hario V60 is a cone-shaped dripper with spiral ridges and a large single hole, giving fast flow and leaving the brewer to control extraction through grind and pouring. A typical recipe starts around 15 grams of coffee to 250 grams of water (about 1:16 to 1:17), ground medium-fine, with water just off the boil (many cafés use around 92 to 96°C). Rinse the paper filter with hot water to remove papery taste and preheat the brewer, then discard the rinse water. Add coffee, level the bed, and pour around twice the coffee’s weight in water to bloom for 30 to 45 seconds, letting gas escape. Then pour in steady stages or one continuous spiral, keeping the water level consistent, finishing around 2 to 3 minutes for a single cup, though time depends on grind and coffee. A gentle swirl at the end flattens the bed for even drawdown. Common problems: fast drawdown and sour taste (grind finer), slow drawdown and bitter taste (grind coarser), and uneven extraction from pouring onto paper edges. V60 suits single cups to order. In busy cafés, offer it as a slower ‘brew bar’ option or restrict it to quiet periods. Guests enjoy watching; it’s a chance to talk coffee. - V60 is a cone with spiral ridges and a large hole - A common ratio is about 1:16 - Rinse paper filters before brewing - Bloom with about twice the coffee weight in water - Total brew time is often 2–3 minutes #### Kalita Wave and flat-bottom drippers The Kalita Wave has a flat bottom with three small holes and wave-shaped paper filters that reduce contact between paper and brewer walls. The flat bed tends to give more even extraction and is more forgiving of pouring technique than the V60, making it popular in cafés for consistency. Typical recipes resemble V60s: around 15 to 20 grams of coffee with 250 to 320 grams of water, ground medium, brewed in pulses over about 3 to 4 minutes. Other flat-bottom drippers include the Origami (with interchangeable cone or wave papers), the Fellow Stagg dripper, the April brewer and the Orea, each with its own flow characteristics. Flat-bottom brewers often taste sweeter and rounder than cones, with slightly less clarity. For cafés, they’re a good choice when several baristas brew pour-over, because results vary less between staff. Wave papers are more expensive and can crush if handled roughly; store them flat. Train with one recipe and a timer. As with all pour-over, use a gooseneck kettle for controlled pouring and scales with timers. Pour-over is labour-heavy; a barista spends several minutes per cup, so price accordingly and consider batch brew for volume. - The Kalita Wave has a flat bed and three holes - Wave papers reduce wall contact - Flat-bottom brewers are more forgiving - Brew time is typically 3–4 minutes - Pour-over is labour-heavy, so price accordingly #### Chemex The Chemex is an hourglass-shaped glass brewer designed in 1941 by chemist Peter Schlumbohm, with a wooden collar and leather tie. It uses thick, bonded paper filters that remove most oils and fines, giving very clean, tea-like coffee with high clarity and light body. Brewing is similar to other pour-overs but on a larger scale: commonly 30 to 50 grams of coffee for 500 to 800 grams of water, ground medium-coarse, with brew times around 4 to 5 minutes. The thick paper slows flow, so grind slightly coarser than for a V60. Rinse the paper well (its papery taste is noticeable), and place the triple-layered side over the spout to stop the paper collapsing into it and blocking airflow. The Chemex suits sharing pots for tables of two to four, adding theatre to a brunch service. Its glass body is fragile and needs careful washing; a bottle brush helps reach inside. Keep a spare. For cafés, a Chemex for two can be priced as a sharing option, which increases spend per table. It’s also a popular retail item. Explain its taste honestly: ‘very clean and light, more like tea; if you like heavier coffee, try the cafetière.’ - Chemex was designed in 1941 - Thick filters give very clean coffee - Grind slightly coarser than for V60 - Place triple-layered paper side over the spout - Great as a sharing pot for tables #### AeroPress The AeroPress, launched in 2005 by inventor Alan Adler’s company, is a plastic syringe-like brewer that combines immersion with pressure through a small paper or metal filter. It’s versatile, quick, durable and easy to clean, which makes it popular for home, travel and some cafés. Recipes vary wildly, and there’s a well-known World AeroPress Championship that showcases creative methods. A simple café recipe: 15 grams of coffee, medium-fine, 230 to 250 grams of water around 85 to 95°C, stir, steep for one to two minutes, then press slowly for about 30 seconds. The ‘inverted’ method flips the brewer to prevent dripping before pressing, but carries a small risk of spills; train carefully if you use it. AeroPress coffee can be clean like a pour-over or heavier and more concentrated, depending on recipe. For cafés, it’s ideal for a single-cup filter menu with minimal kit and fast turnaround, and works well at events and pop-ups. It also makes a concentrate that can be diluted for an Americano-like drink, useful when your espresso machine breaks down. Brewers are cheap, but plastic wear and staining occur; replace seals and parts as needed. It sells well as retail with a bag of coffee. - Launched in 2005 - Combines immersion with pressure - Steep around 1–2 minutes then press - The inverted method risks spills - A useful backup when the espresso machine fails #### Cafetière (French press) The cafetière, known as the French press in the US, is a full-immersion brewer with a metal mesh plunger. It’s the most familiar filter method to British guests and works well for sharing pots at brunch. Use coarse grind, around 60 to 70 grams of coffee per litre of water (roughly 1:15 to 1:17), water just off the boil, and steep around four minutes. A refined method: after four minutes, break the crust, skim off floating foam and grounds, then wait several more minutes for fines to settle before gently pressing just to the surface and pouring slowly; this gives cleaner, sweeter coffee. Because mesh filters let oils and fines through, cafetière coffee has heavy body and some sediment. Pour all the coffee out once brewed, or it keeps extracting and becomes bitter; serving the whole pot to a table means the last cup will taste stronger. Glass cafetières break; use stainless steel or double-walled versions in busy cafés. Clean mesh filters thoroughly by dismantling them regularly, as oils build up. Cafetières are cheap to buy and simple to train, making them a good entry-level filter option for cafés and hotels. Price per pot for two to four people. - Use a coarse grind and steep about four minutes - Skimming the crust gives cleaner coffee - Mesh filters let oils and fines through - Coffee left on grounds turns bitter - Dismantle mesh filters regularly to clean #### Batch brew Batch brew is filter coffee made in larger quantities by automatic brewers such as Marco, Fetco, Bunn, Moccamaster and Bravilor machines. In speciality cafés it’s become a way to serve high-quality filter coffee fast, often as a cheaper alternative to an Americano. Good batch brew needs correct ratio (often around 60 to 65 grams per litre), a grinder suited to filter, quality paper filters, correct water temperature (around 92 to 96°C) and a brewer that distributes water evenly. Keep it in insulated airpots or thermal servers rather than on hotplates, which cook the coffee and make it bitter. Freshness matters: discard batch brew after a set time (many cafés use 30 to 60 minutes) and brew smaller batches more often in quiet periods. Label airpots with brew time. Batch brew is very fast to serve, so it helps reduce queues during rushes, and it costs less coffee per cup than espresso drinks in many cases. Train staff to promote it: ‘our filter is ready to go now, and it’s really good today.’ Some cafés offer free refills for sit-in customers, which builds loyalty. Keep brewers clean with dedicated detergents and check spray heads for scale and blockages. - Batch brew serves filter coffee quickly - A common ratio is about 60–65g per litre - Use thermal servers, not hotplates - Discard after a set time, often 30–60 minutes - Promote batch brew to cut queues #### Syphon brewing The syphon (vacuum pot) is a theatrical brewer from the nineteenth century that uses vapour pressure and vacuum. Water in a lower chamber is heated, often by a halogen beam heater, butane burner or alcohol lamp, and pushed up into an upper chamber where it mixes with coffee. After a short steep, the heat is removed; as the lower chamber cools, a vacuum pulls the brewed coffee down through a cloth, paper or metal filter, leaving the grounds above. Syphon coffee tends to be clean, aromatic and hot, with a distinctive tea-like clarity. Recipes vary, but many use around 15 to 20 grams of coffee with 240 to 300 millilitres of water, a medium grind and a total contact time of around 1 to 2 minutes, stirring gently. It’s visually striking and can draw attention in a café or bar, but it’s slow, fiddly and fragile; glass chambers break and cloth filters need careful cleaning and storage (often kept in water in the fridge to prevent odours). Using naked flames or heaters requires risk assessment. For most cafés, syphon is a special menu item or event feature rather than a core offering. Price it as an experience, not just a cup. - Syphons use vapour pressure and vacuum - Coffee is drawn down as the lower chamber cools - Cloth filters need careful cleaning and storage - Syphon coffee is clean and aromatic - Naked flames require risk assessment #### Moka pot The moka pot, invented in Italy in the 1930s and associated with Bialetti, is a stovetop brewer that pushes hot water up through a bed of coffee using steam pressure, producing a strong, concentrated brew. It isn’t true espresso: pressure is far lower (around 1 to 2 bar compared with espresso’s 9 bar), and there’s no real crema. To brew well: fill the bottom chamber with hot water up to the valve, fill the basket with fine-medium coffee without tamping, assemble carefully (using a cloth to hold the hot base), heat on medium, and remove from heat as soon as the coffee starts to gurgle, to avoid a burnt, metallic flavour. Cool the base under cold water to stop extraction. Moka pots are mostly a home brewing method, but some cafés and restaurants use them for a nostalgic Italian-style coffee or to serve at the table. They’re also popular retail items. Train staff on safety: the safety valve must never be blocked, and the pot must never be filled above it. Avoid aluminium pots in dishwashers, as they can discolour. When guests ask why their home moka tastes bitter, the usual culprits are too high heat, too fine grind and leaving it on the stove too long. - Invented in Italy in the 1930s - Moka pots use around 1–2 bar pressure - Moka coffee is not true espresso - Remove from heat when it starts to gurgle - Never block or overfill the safety valve #### Clever dripper and immersion-drip hybrids The Clever Dripper is a cone brewer with a valve at the bottom: coffee and water steep together as in a cafetière, then the brewer is placed on a cup or jug, which opens the valve and lets coffee drain through a paper filter. It combines the forgiving nature of immersion with the clean cup of paper filtration, making it ideal for cafés that want consistent single-cup filter without needing skilled pouring. A simple recipe: 18 to 20 grams of medium-coarse coffee, 300 grams of water around 93 to 96°C, stir, steep around 2 to 3 minutes, then drain for about a minute. Other hybrids include the Hario Switch, which adds a switchable valve to a V60, allowing immersion or pour-over. These brewers are easy to train and reduce variation between staff. They also free baristas to do other tasks while the coffee steeps, which matters in a busy café. Keep paper filters and brewers clean, and rinse paper before use. Clever drippers are plastic; replace when scratched or stained. They make a good retail option for guests who want café-style filter at home without buying a gooseneck kettle, and they can be explained easily at the counter. - The Clever Dripper steeps then drains - Combines immersion and paper filtration - Easy for staff to brew consistently - The Hario Switch adds a valve to a V60 - Frees baristas during steeping #### Filter grind size and recipe adjustment Grind size is the main tool for adjusting filter coffee. Finer grinds extract faster and slow drawdown in pour-over; coarser grinds extract slower and drain faster. Immersion methods (cafetière, Clever) are less sensitive to flow, so grind mostly controls extraction rate and sediment. Common reference points: cafetière coarse, like sea salt; batch brew and Chemex medium-coarse; V60 and Kalita medium to medium-fine; AeroPress medium-fine to fine depending on recipe; moka pot fine-medium. Grinders differ, so these are only guides; use a consistent grind setting per recipe and adjust from taste. Ratio controls strength: more coffee per water gives a stronger cup. Temperature affects extraction too; lighter roasts usually like hotter water. Adjust one variable at a time and keep notes. Fines (very small particles) cause clogging and bitterness in pour-over; a better grinder produces fewer fines. Some cafés sieve coffee for competition, but that’s not practical day to day. For retail, offer to grind beans for customers’ brewers; ask what they use and grind accordingly. Ground coffee goes stale quickly, so suggest buying smaller bags or investing in a home grinder, and explain why. - Grind size is the main filter adjustment - Finer grinds slow pour-over drawdown - Ratio controls strength - Fines cause clogging and bitterness - Ask retail customers which brewer they use #### Kettles and pouring technique Pour-over brewing relies on controlled pouring, which is why gooseneck kettles with narrow spouts are standard. They let baristas pour slowly and accurately, controlling flow rate and where water lands. Many cafés use electric gooseneck kettles with temperature control (from brands such as Fellow, Hario, Bonavita and Brewista), which hold water at set temperatures. Pouring technique: keep a steady, gentle stream; pour in small circles from the centre outwards and back, avoiding the paper edges, which can let water bypass the coffee bed; keep the water level consistent; and avoid pouring too high, which agitates the bed excessively. Some recipes use pulse pours (several separate pours) for control; others use one continuous pour. Consistency matters more than any single technique. Timers and scales under the brewer guide the pour. Kettles need descaling in hard-water areas; scale affects temperature accuracy and flavour. In busy cafés, multiple kettles or a hot water tower with a temperature setting help with speed. Kettle handles get hot; train staff to use the handle properly and not lean over steam. For training, practise pouring with water only onto scales, aiming for a target weight over a set time. - Gooseneck kettles allow controlled pouring - Temperature-controlled kettles hold set temperatures - Avoid pouring onto paper edges - Consistency matters more than technique choice - Practise pouring onto scales with water #### Filter papers and filter types Filters affect taste and body. Paper filters remove most oils and fines, giving clean, bright coffee; they come bleached (white) or unbleached (brown), with unbleached papers often imparting more papery taste unless rinsed well. Thickness and pore size vary between brands and brewer types, so use papers designed for your brewer. Metal mesh filters, used in cafetières and some pour-over cones, let oils and fines through, producing heavier, fuller coffee with sediment. Cloth filters, used in some syphons and traditional pour-over, give clean but rounded coffee; they need careful cleaning and storage to avoid stale or sour odours. There are also reusable plastic and nylon mesh filters for home brewers. In cafés, paper is standard for pour-over and batch brew; consistent quality matters, so buy from reliable suppliers and check they fit correctly to avoid collapse or bypass. Rinse papers with hot water before brewing to preheat the brewer and remove paper taste. Compost used papers with grounds if your waste service allows. Store papers in a dry place away from strong odours, as paper absorbs smells. For health questions, there is some evidence that paper filters retain cafestol, a compound in coffee oils linked to raised cholesterol, but avoid making health claims. - Paper filters remove most oils and fines - Unbleached papers need thorough rinsing - Metal filters give heavier body - Cloth filters need careful storage - Avoid making health claims about filters #### Turkish and Arabic coffee Turkish coffee is made by boiling very finely ground coffee, like powder, with water and often sugar in a small pot called a cezve or ibrik, then pouring it unfiltered into small cups, where grounds settle at the bottom. Sugar is added during brewing, so ask guests how sweet they want it (plain, medium or sweet) before making it. The coffee is heated slowly until foam rises; traditionally the foam is spooned into cups and the coffee briefly reheated. It’s served with water and often a sweet such as Turkish delight. Turkish coffee culture and tradition is recognised by UNESCO as intangible cultural heritage. Arabic coffee (qahwa), common across the Gulf, is lightly roasted and often brewed with cardamom, sometimes saffron, served in small handleless cups alongside dates, with rituals around pouring and refilling. Both styles appear in UK Middle Eastern, Turkish and Levantine restaurants and cafés. Getting them right requires a very fine grind (special grinders or pre-ground Turkish coffee), the right pot and patience. Staff should warn guests not to drink the grounds at the bottom. Sand-heated brewing (hot sand trays) is spectacular but requires safety measures for hot surfaces. - Turkish coffee is boiled unfiltered in a cezve - Sugar is added during brewing - Grounds settle at the bottom of the cup - Turkish coffee culture is UNESCO-recognised - Arabic coffee often includes cardamom ### Café Workflow #### Café order flow and ticketing How orders travel from till to bar determines speed and accuracy. Common systems: verbal calling (the till person shouts orders to the bar), printed tickets from the POS, cups marked with abbreviations, or kitchen display screens for the bar. In busy cafés, marking cups with shorthand (‘FW O’ for flat white oat, ‘D’ for decaf, ‘XH’ for extra hot) and lining them up in order is quick and reliable. Tickets or screens help with complex orders, tables and food. Whatever the system, include: drink type, size, milk, extra shots, decaf, syrups, temperature, allergens, name or table number, and whether it’s takeaway or sit-in. Consistent abbreviations are essential; write them on a card for new staff. Sequence matters: baristas usually work in order but group similar drinks to share milk (for example, two oat lattes together). Allergy orders need extra care and clear marking. Mistakes often come from mishearing, unclear shorthand or orders out of sequence, especially during rushes. Repeat back complex orders. A short huddle before service to confirm abbreviations and any menu changes prevents many errors. POS systems with modifiers make orders clearer and data more useful for stock and sales analysis. - Mark cups with consistent abbreviations - Include milk, size, decaf and allergens on every order - Group similar drinks to share milk - Repeat back complex orders - POS modifiers improve accuracy and data #### Speed of service In UK cafés, morning speed is everything: commuters may walk out if the queue looks slow. Measure speed as time from order to handoff, and aim for consistent times, perhaps two to four minutes for most drinks in a busy café, depending on format. Factors: staffing levels and roles, layout, machine and grinder capacity, menu complexity, payment speed and prep. Simple fixes: pre-stock cups, lids and milk before the rush; prep pastries and grab-and-go food; keep the menu tight during peak times; use batch brew for filter coffee; pre-dial grinders before opening; and have a runner to clear, restock and hand out drinks. Two baristas with clear roles (shots and milk) can produce far more than two working independently. Watch the queue from the bar; the till person can take orders ahead and mark cups so drinks are already moving by the time payment is done. Contactless payments and mobile ordering speed things up. Track your peak hours from POS data and staff accordingly. Speed must not sacrifice quality or safety; rushed milk and sloppy shots drive regulars away just as fast as slow service. Train speed through practice drills during quieter periods. - Measure time from order to handoff - Pre-stock cups, lids and milk before rushes - Split barista roles into shots and milk - Use POS data to staff peaks - Drill speed during quiet periods #### Two-barista rhythm When two baristas share a machine, rhythm and communication make or break speed. A common split: the ‘shot barista’ grinds, doses, tamps and pulls shots, handles Americanos and espresso drinks, and calls shots as they finish; the ‘milk barista’ steams milk, pours latte art, and finishes and hands off drinks. The shot barista works one or two orders ahead so shots are ready when milk is done. They communicate constantly: ‘two flat whites, one oat latte’; ‘shots up’. Hand signals and short calls help in noisy environments. In larger cafés, a third person takes orders and handles food, or acts as a runner and dishwasher. Each role needs clear responsibilities, including cleaning: who knocks out, who wipes the wand, who restocks milk. Rotate roles across shifts so everyone stays skilled, but keep the strongest baristas on the busiest shifts. Train new baristas on shots first, then milk, before combining. Small habits matter: always return jugs to the same place, keep cloths labelled for wand and portafilter, and clean as you go. A good two-barista team can sustain high volumes without rushing; a poorly coordinated pair collides, duplicates work and makes mistakes. - Split into shot barista and milk barista - Shot barista works one or two orders ahead - Communicate orders and shot status out loud - Assign cleaning responsibilities by role - Rotate roles to maintain skills #### Handoff and calling drinks The handoff point is where most mix-ups happen: two oat flat whites, one decaf, and two guests reaching for the same cup. A clear handoff area, away from the till queue, with drinks lined up in order, helps. Call drinks clearly: ‘Oat flat white for Sam’ rather than ‘flat white’. Use names or order numbers for takeaway; for table service, number tables and deliver with a tray. Mark decaf and allergy drinks clearly, for example with a sticker or a lid marking, and hand them directly to the guest rather than leaving them on the counter. Check each drink against the order before handing off. Lids should be fitted securely and checked; a loose lid that spills on a customer is both a complaint and a potential scald risk. Offer sugar and stirrers from a self-service station rather than at the handoff to keep flow moving. For delivery-app orders, have a separate collection shelf and sealed bags. If a guest says a drink is wrong, remake it without argument. Handoff is also the last moment for hospitality: eye contact, a thank you and a quick check (‘anything else?’) can turn a transaction into a relationship, and encourage repeat visits. - Keep handoff away from the till queue - Call drinks with milk and name - Hand allergy and decaf drinks directly to guests - Check lids are secure before handoff - Separate delivery-app collection points #### Takeaway cups and lids Takeaway cups shape both experience and costs. Sizes in UK cafés are commonly 8oz, 12oz and 16oz, with 4oz for espresso and cortados. Single-wall paper cups need sleeves for hot drinks; double-wall or ripple cups provide insulation without sleeves. Most paper cups have a plastic or bio-based lining, making them hard to recycle in standard paper streams; specialist cup recycling schemes and collection points exist. Lids range from polystyrene and polypropylene to paper and plant-based materials. Check UK rules: single-use plastic items such as expanded polystyrene cups and food containers are banned in England from 2023 for supply, with similar bans in Scotland and Wales, and the list of restricted items has grown; ensure your packaging complies. Branded cups help marketing but carry higher costs and minimum orders. Choose lid fit carefully; mismatched lids cause spills and complaints. Store cups off the floor in dry areas. Track cup cost per drink, which can add tens of pence. Encourage reusable cups with discounts; many cafés offer a reduction for bringing your own, and some add a charge for disposable cups. Consider whether lids are needed for sit-in customers using takeaway cups; ceramic cups are often better for both experience and waste. - Common takeaway sizes are 8, 12 and 16oz - Paper cups usually have a plastic or bio lining - Expanded polystyrene cups are banned in England - Mismatched lids cause spills and complaints - Track cup cost per drink #### Reusable cups and cup charges Reusable cups reduce waste and can build loyalty. Many UK cafés offer a discount for customers bringing their own cups, often somewhere around 10 to 50 pence, or add a charge for disposable cups to nudge behaviour. Research and trials in the UK have suggested that charges on disposables tend to change behaviour more than discounts, but every café knows its own customers. Practicalities: reusable cups come in different sizes, so adjust recipes; make sure cups are clean before filling (staff can refuse visibly dirty cups); avoid touching the inside rim with jugs or hands; and don’t place customers’ cups on food-contact surfaces where contamination could occur. Food safety guidance generally allows reusable cups if handled hygienically. Some cafés join cup-return schemes where customers borrow a cup and return it to any participating outlet. Selling branded reusable cups adds retail revenue and marketing. During the pandemic, some cafés stopped accepting reusables; those concerns have largely faded, but have a policy and train staff on it. Communicate your offer clearly at the till and on menus. Record reusable cup usage in the POS to track the impact and report it in sustainability messaging, but avoid exaggerating results. - Reusable cup discounts are common - Charges on disposables may change behaviour more - Staff can refuse visibly dirty cups - Avoid touching inside rims with jugs - Track reusable cup usage in the POS #### Syrups, sauces and sweeteners Syrups and sauces add flavour and margin: vanilla, caramel, hazelnut and seasonal flavours such as gingerbread or pumpkin spice. Brands like Monin, Da Vinci and Sweetbird are common, along with sugar-free versions. Pumps standardise portions; a typical pump delivers a set volume (check the manufacturer), and cafés usually use one or two pumps per drink depending on size. Price syrups as an add-on, often around 30 to 70 pence. Homemade syrups (vanilla, cinnamon, brown sugar) can be cheaper and give a point of difference but need food safety controls: proper sugar ratios, storage, labelling, dating and shelf-life testing, as low-sugar syrups can grow mould. Sauces such as chocolate and caramel may contain milk and other allergens; record them in your allergen matrix. Sweeteners on the self-service counter include white and brown sugar, honey, and sugar-free options; offer them in sachets or dispensers. Clean pumps regularly; sugary residue attracts insects and blocks nozzles. Don’t overdo syrups in speciality drinks; one pump in a flat white is often plenty. Rotate seasonal flavours to create interest and repeat visits, but keep the core list short to avoid clutter and wasted stock. - Pumps standardise syrup portions - Price syrups as add-ons - Homemade syrups need shelf-life controls - Sauces may contain milk allergens - Clean pumps regularly #### Seasonal drink specials Seasonal specials drive interest, social media posts and higher spend. Common UK seasons: autumn spice lattes, Christmas gingerbread and orange mochas, spring floral or honey drinks, and summer iced specials and coffee tonics. Planning: decide the drink concept, test recipes with your espresso and milks, cost them accurately, choose names and descriptions, prepare allergen information, and train staff before launch. Use ingredients that cross over with your existing stock, such as a spice syrup that also flavours a cake. Keep the number of specials small, typically one to three per season, to protect speed. Make them easy to produce during rushes: avoid multiple garnishes or complicated layering. Promote them with good photos on social media, menus and counter signage. Track sales: if a special doesn’t sell after a few weeks, drop it. Specials can also test ideas for the permanent menu. Avoid trademarked names of competitors’ drinks; describe yours in your own words. For iced drinks in summer, ensure you have enough ice, cups and fridge space. Seasonal specials should be priced at a premium reflecting their extra ingredients and novelty, often around 30 to 80 pence more than a standard latte. - Keep seasonal specials to one to three per season - Cost and test recipes before launch - Use ingredients that cross over with existing stock - Avoid competitors’ trademarked drink names - Drop specials that don’t sell #### Allergen management on the coffee bar UK food businesses must provide accurate allergen information for the fourteen regulated allergens, and since October 2021 food prepacked for direct sale (such as sandwiches made and wrapped on site) needs full ingredient labelling with allergens emphasised, often referred to as Natasha’s Law. On the coffee bar, allergens hide in milks (milk, soya, tree nuts, oats that may contain gluten), syrups and sauces (milk, sometimes nuts), chocolate, toppings, biscuits served with drinks, and cakes. Keep an allergen matrix covering every drink and add-on, updated whenever suppliers or recipes change. Train staff to ask about allergies, to check the matrix rather than guess, and to communicate allergy orders clearly to the bar. Use separate jugs and clean wands for allergy orders, avoid shared spoons and cloths, and store allergen-containing ingredients carefully. Staff should be honest about cross-contact: if you can’t guarantee a nut-free drink because of shared equipment, say so. Display a notice inviting customers to ask about allergens. Keep supplier specifications on file. Mistakes can be fatal; a clear system, training and checks are essential. Review procedures regularly and after any incident or near miss. - Fourteen allergens must be declared in the UK - Natasha’s Law covers food prepacked for direct sale - Keep an allergen matrix for every drink and add-on - Use separate jugs and clean wands for allergy orders - Be honest about cross-contact risks #### Opening the coffee bar A consistent opening routine gets the bar ready before the first rush. Typical steps: switch on the machine with enough time to heat fully (many commercial machines need 20 to 45 minutes; timers help), check pressure and temperature gauges, flush groups, insert clean portafilters and let them heat. Fill hoppers with fresh beans (checking roast dates), purge grinders, and dial in the house espresso, decaf and any single origin, recording settings. Check milk deliveries for temperature and dates, stock the milk fridge, and set up jugs and cloths. Stock cups, lids, sleeves, stirrers, sugar and napkins. Prep batch brew and check the hot water supply. Set up the till, float and card machine. Check cleaning stations, sanitiser concentrations and hand-washing supplies. Check fridges’ temperatures and record them as part of your food safety management system. Turn on music and lights, and check the front of house for cleanliness. A printed opening checklist, signed off by the opener, ensures nothing is forgotten, especially when staff change. Allow time for staff coffee: a barista tasting the coffee is part of dialling in, and a team that starts calmly with a decent coffee serves better. - Allow time for the machine to fully heat - Dial in every grinder before opening - Check milk deliveries for temperature and dates - Record fridge temperatures - Use a signed opening checklist #### Closing the coffee bar Closing well makes tomorrow easier and protects equipment. A typical close: backflush groups with detergent, rinse, and clean shower screens and gaskets; soak and scrub portafilters and baskets; clean steam wands thoroughly and soak tips if needed; empty and wash drip trays; empty knock boxes and clean them; empty hoppers into airtight containers; brush and clean grinders; clean milk jugs and store them upside down to dry; wipe all surfaces; clean batch brewers and airpots; empty and clean the hot water dispenser tray; check and record fridge temperatures; check milk dates and discard out-of-date stock; stock cups and lids for the morning; take out rubbish and recycling; mop floors behind the bar; and turn off or set the machine to standby as advised by the manufacturer. Cash up the till and record waste. A closing checklist with initials keeps it consistent. Note equipment problems for the manager or technician. Leave clear handover notes, for example ‘grinder ran slow at 3pm’ or ‘running low on oat milk’. A rushed close leads to rancid oils, smelly drains and slow mornings. Allow enough paid time for closing tasks; underestimating them is a common cause of staff resentment and corner-cutting. - Backflush and clean groups at every close - Empty hoppers into airtight containers - Store jugs upside down to dry - Leave clear handover notes - Allow paid time for closing tasks #### Handling coffee complaints Coffee complaints are common and usually simple: too cold, too weak, too milky, wrong milk, wrong size, bitter, or not what the guest expected. The best response is to remake it quickly and politely, without argument, and ask a gentle question to understand the issue (‘Was it too strong, or not hot enough?’). Use the feedback: if several guests complain about bitterness, check dial-in and cleaning; if many say drinks are cold, check milk temperature and cups. Train staff not to take complaints personally and not to blame colleagues or customers. Offer alternatives if the drink doesn’t suit them, for example suggesting a flat white for someone who found a latte weak. For repeat complainers or unreasonable requests, managers should handle the conversation. Record complaints in a simple log to spot patterns. Online reviews often mention coffee quality; respond calmly and professionally, without revealing personal details. Remember that taste is subjective: speciality cafés sometimes face complaints from guests used to darker roasts, so offering a choice (for example, a ‘classic’ blend) can help. Most importantly, the cost of remaking a coffee is small compared with the value of a regular who feels heard. - Remake quickly and without argument - Ask what was wrong to learn from it - Look for patterns in complaints - Managers should handle difficult conversations - A remake costs far less than losing a regular #### Barista training plan A structured training plan turns new hires into confident baristas faster. A typical progression: week one, food safety, allergens, cleaning routines, till and customer service, plus basic coffee knowledge and tasting; week two, espresso basics (dosing, tamping, extraction, dialling in) under supervision; weeks three and four, milk steaming and pouring basic drinks, latte art basics, and making drinks during quieter periods; then gradual introduction to busy shifts with support. Use a written checklist with sign-offs for each skill, such as pulling consistent shots, steaming milk to temperature, cleaning the machine, and handling allergens. Pair trainees with experienced baristas. Set practice targets: for example, steaming milk to correct texture ten times in a row, or pouring a heart consistently. Include tasting and calibration sessions so they learn what good coffee tastes like. Formal courses (such as SCA barista modules or roaster training days) can supplement in-house training. Budget for training time and wasted coffee and milk; practice with water and soapy water for milk texturing can reduce waste. Review progress regularly and give feedback. Well-trained staff are faster, make fewer mistakes, and are more likely to stay. - Start with food safety, allergens and cleaning - Teach espresso before milk - Use checklists with skill sign-offs - Practise milk texturing with soapy water - Budget for training time and waste #### Hiring and keeping baristas Good baristas are in demand, and staff turnover is costly. When hiring, look for attitude, reliability and hospitality as much as coffee skills; coffee can be taught, personality is harder. Practical trial shifts (paid, as required for genuine work) show how candidates handle pressure and customers. Pay must meet at least the National Minimum Wage or National Living Wage for the worker’s age, which rises each April; many speciality cafés pay above it to attract skilled staff. Tips must be passed to workers in full under the Employment (Allocation of Tips) Act 2023, which came into force in October 2024, and employers must have a written tipping policy. Staff retention depends on fair pay, predictable rotas, respect, training and progression, such as head barista roles, roasting experience or management training. Regular feedback, staff coffee allowances and discounts help. Avoid unpaid overtime, and ensure breaks meet legal requirements. Recognise good work publicly. Exit interviews can reveal problems. Keeping a strong team saves recruitment costs and maintains coffee consistency, which regulars notice. Encourage staff to attend coffee events, competitions and cuppings; it builds enthusiasm and skills, and they bring new ideas back to the café. - Hire for attitude and reliability - Trial shifts for genuine work must be paid - Tips must be passed to workers in full - A written tipping policy is required - Progression and training improve retention #### Mobile ordering and click-and-collect Mobile ordering lets customers order and pay ahead, collecting their drink without queuing. It can increase speed and average spend, but it creates challenges: mobile orders arrive while baristas are serving the in-store queue, so drinks can pile up or go cold if customers arrive late. Solutions: set realistic preparation times, add slots during busy periods, and use a separate ticket printer or display for mobile orders. A dedicated collection shelf, clearly signposted, prevents confusion and stops in-store customers taking mobile orders. Name labels on cups help. Integrate mobile orders with the POS for accurate stock and sales data. Some cafés make drinks only when customers check in or arrive (using geolocation features) to avoid cold drinks. Third-party apps charge commission; compare costs with your own branded app or POS-integrated solutions. Delivery platforms (such as Deliveroo, Uber Eats and Just Eat) also charge commission and require packaging that keeps drinks safe in transit; hot milk drinks often suffer in delivery. Monitor reviews and complaints from mobile users. Mobile ordering data can reveal regulars’ habits and support loyalty schemes. Make sure allergen information is available in apps, as required by law. - Mobile orders can pile up during rushes - Use separate printers or displays for mobile orders - Signpost a dedicated collection shelf - Third-party apps and delivery platforms charge commission - Allergen information must be available in apps #### Drink sizes and recipe standards Recipe standards keep drinks consistent and costs predictable. For each drink and size, specify: cup type and size, espresso recipe (dose, yield, number of shots), milk type and amount, milk temperature and foam depth, syrup pumps, toppings, and final presentation. Photograph each drink for reference. Size choices affect coffee perception: a 16oz latte with a double shot tastes milky; adding a third shot keeps it balanced but raises cost. Some cafés keep the same double shot across sizes and charge more for extra milk, which can disappoint coffee lovers. Communicate standards in a recipe book or laminated cards at the bar. Cost each recipe precisely, including coffee, milk, syrups, cup, lid, sleeve and napkin, and set selling prices for target gross profit. Review standards when coffee or milk changes. Train staff to follow them strictly; ‘free-pouring’ extra milk or syrup erodes margin. However, allow flexibility for customer requests such as ‘extra hot’ or ‘half shot’. Regular audits, such as weighing a random drink’s milk or checking cup fill lines, keep standards in place. Consistent drinks build trust: a regular wants their coffee to taste the same every day. - Specify cup, shots, milk, temperature and toppings per size - Photograph drinks for reference - Larger sizes may need an extra shot - Cost every component including cups and lids - Audit drinks regularly ### Tea #### Oolong tea Oolong sits between green and black tea in oxidation, anywhere from lightly oxidised and floral to heavily oxidised and roasted. Leaves are withered, bruised by tossing or rolling to start oxidation, then heated to stop it at the chosen point, rolled into twisted strips or tight balls, and often roasted. Taiwanese high-mountain oolongs taste buttery, creamy and floral; Tieguanyin from Fujian ranges from orchid-like green styles to toasty traditional ones; Da Hong Pao and other Wuyi rock teas are darker, mineral and roasted; Dong Ding is often medium-roasted with nutty sweetness; ‘milk oolong’ is naturally creamy, though some versions are flavoured, which should be disclosed. Brewing: water around 85 to 95°C depending on style, with greener oolongs cooler and roasted ones hotter. Western-style brewing uses a few grams per cup for three to five minutes; gongfu style uses more leaf in a small pot or gaiwan, with many short infusions of 20 to 60 seconds, each tasting different. Oolong leaves can be re-steeped several times, which is good value for guests and a talking point. On a UK café menu, oolong appeals to curious tea drinkers and those who find green tea grassy. Serve it without milk, and explain re-steeping so guests get their money’s worth. - Oolong is partially oxidised - Styles range from floral green to dark roasted - Gongfu brewing uses many short infusions - Oolong leaves can be re-steeped several times - Serve without milk #### Pu-erh and dark teas Pu-erh is a fermented and aged tea from Yunnan, China, made from large-leaf tea plants. There are two main styles. Raw (sheng) pu-erh is pressed into cakes and ages slowly over years, changing from bright, bitter and astringent to mellow, complex and woody. Ripe (shou) pu-erh undergoes an accelerated ‘wet piling’ fermentation, giving dark, earthy, smooth tea with notes of forest floor, leather and dark chocolate in a matter of months. Other ‘dark teas’ (hei cha) come from Hunan, Guangxi and elsewhere. Pu-erh is often sold as compressed cakes, bricks or small portions; break off pieces with a pu-erh knife. Rinse the leaves briefly with hot water before brewing to wake them and wash off dust. Brew with water near boiling, using short infusions gongfu style or longer western-style steeps. Ripe pu-erh is forgiving and makes a rich, dark tea that can appeal to coffee drinkers; it can also take a little milk, though purists disapprove. Aged raw pu-erh can be very expensive and is mostly a specialist product. For cafés, a ripe pu-erh is a good addition for guests wanting something deep and different. Avoid health claims such as weight loss, which are regulated and unsupported. - Pu-erh comes from Yunnan, China - Raw pu-erh ages slowly - Ripe pu-erh uses accelerated wet piling - Rinse leaves before brewing - Avoid weight-loss health claims #### Rooibos and honeybush Rooibos (‘red bush’ in Afrikaans) is not tea from Camellia sinensis but a herbal infusion from a South African plant grown in the Cederberg region of the Western Cape. It’s naturally caffeine-free and low in tannins, so it doesn’t turn bitter with long steeping. Traditional ‘red’ rooibos is oxidised, giving a sweet, nutty, honeyed flavour; green rooibos is unoxidised, lighter and grassier. Brew with boiling water for around five minutes or longer; it can take milk and sugar, which makes it a popular caffeine-free alternative to builder’s tea, especially for pregnant guests and evening drinkers. Rooibos lattes and ‘red espresso’ (finely ground rooibos brewed through an espresso machine) appear on some menus; clean equipment thoroughly afterwards, as rooibos flavour lingers. Honeybush, a related South African plant, is sweeter and more floral. Rooibos holds a geographical indication in some markets, reflecting its origin. Both are widely available in tea bags and loose leaf. Rooibos chai, blended with spices, provides a caffeine-free chai option. Price rooibos like other teas; cost per cup is low. Train staff to call it a herbal tea or infusion and to confirm it’s caffeine-free when asked, which builds trust. - Rooibos is a South African herbal infusion - Naturally caffeine-free and low in tannins - Takes milk and sugar well - Red espresso brews rooibos through an espresso machine - Honeybush is a sweeter relative #### Herbal infusions (tisanes) Herbal teas, properly called tisanes or infusions, are made from plants other than Camellia sinensis: peppermint, chamomile, lemon verbena, hibiscus, ginger, lemongrass, fennel, nettle, rosehip and countless blends. Most are caffeine-free (exceptions include yerba mate and guayusa). In the UK, peppermint and chamomile dominate café sales, followed by fruit blends. Brew with boiling water for most herbs, steeping five minutes or more to extract full flavour; delicate flowers may prefer slightly cooler water. Fresh mint tea, made with a generous bunch of fresh mint leaves in a glass or pot, is popular and visually appealing, but requires fresh stock and has a short shelf life. Moroccan mint tea combines green tea and mint, often sweetened. Fruit blends often contain hibiscus, which gives a bright red colour and tart flavour, and dried fruit pieces that can contain allergens or sulphites; check labels. Some herbs are unsuitable for certain people, such as pregnant guests; avoid giving medical advice and refer them to their healthcare professional. Don’t make health claims such as ‘detox’ or ‘aids digestion’ on menus unless they are authorised claims under nutrition and health claims rules. Serve herbal infusions with a timer or remove the bag or leaves after steeping. - Tisanes are infusions of plants other than tea - Most herbal teas are caffeine-free - Fresh mint tea needs fresh stock - Fruit blends may contain sulphites - Avoid unauthorised health claims like ‘detox’ #### Matcha Matcha is finely ground Japanese green tea made from shade-grown leaves (tencha) that are steamed, dried, destemmed and stone- or mill-ground into powder. Shading boosts chlorophyll and amino acids such as L-theanine, giving vivid green colour and umami-sweet flavour. Grades vary: ‘ceremonial’ is a marketing term for high-quality matcha suitable for drinking with water; ‘culinary’ grades are cheaper and more astringent, suited to lattes and baking. Prices vary enormously, and global demand surges have caused shortages and price rises in recent years. To prepare traditionally, sift around 1 to 2 grams into a bowl, add a little water around 70 to 80°C, and whisk vigorously with a bamboo whisk (chasen) in a zigzag motion until frothy. For lattes, whisk matcha with a little hot water into a smooth paste first, then add steamed milk; or shake with cold milk and ice for iced matcha. Clumps are the main quality problem, so sift. Matcha contains caffeine, roughly comparable to a cup of tea or more depending on dose. Store it airtight, cool and dark, ideally refrigerated once opened, because it oxidises quickly and turns dull and bitter. Price matcha lattes at a premium to reflect ingredient cost. - Matcha is made from shade-grown tencha - ‘Ceremonial grade’ is a marketing term - Sift matcha to avoid clumps - Whisk with water around 70–80°C - Matcha oxidises quickly once opened #### Chai and chai lattes Chai simply means tea in Hindi and many other languages, but in UK cafés it usually means masala chai: black tea brewed with spices such as cardamom, cinnamon, ginger, cloves and black pepper, with milk and sugar. In India, chai is typically simmered on the stove with milk, water, tea, spices and sugar, then strained, producing a strong, sweet, spicy drink. Café chai lattes are often made from a syrup, powder or liquid concentrate mixed with steamed milk, which is fast but can be very sweet. Spiced chai concentrates can be made in-house by simmering tea and spices with water and sugar, then straining and refrigerating; this needs food safety controls and labelling. ‘Dirty chai’ adds a shot of espresso. Chai lattes are popular in autumn and winter and with guests who don’t drink coffee. Plant milks, especially oat, work well. Check allergens: powders may contain milk; some blends contain nuts or gluten. Rooibos chai provides a caffeine-free version. If you serve chai in a traditional style, consider describing its origins accurately and respectfully on the menu. Price chai lattes similarly to coffee lattes; a well-made, less-sweet house chai can become a signature drink that sets you apart. - Chai means tea in Hindi - Masala chai combines black tea and spices - Café chai is often made from syrup or powder - Dirty chai adds espresso - Powders may contain milk allergens #### Breakfast blends and builder’s tea English Breakfast tea is a blend of black teas, traditionally including Assam (malty, strong), Ceylon (bright, brisk) and African teas from Kenya or Malawi (fast-brewing, coloury). It’s designed to stand up to milk and sugar. ‘Builder’s tea’ is the British nickname for strong, milky, sweet tea, usually made with a bag left in long enough to make it dark orange-brown. Irish Breakfast blends tend to be even stronger and maltier, often Assam-heavy. Scottish Breakfast blends are similarly robust. Most UK tea is sold in bags containing CTC (crush, tear, curl) tea, which brews fast and strong. In cafés, a good breakfast tea is essential; many British guests judge a café by its ‘normal tea’. Serve it with boiling water, give guests the option of a pot or mug, and offer milk on the side or ask how they take it. The milk-first or milk-after debate is more cultural than scientific; adding milk after lets guests judge strength. Offer a choice of brands if possible, as regional loyalty is strong: Yorkshire Tea, PG Tips, Tetley and Twinings all have fans. Price tea fairly; tea is cheap per cup, but a good pot is an important part of the British café offering. - English Breakfast blends Assam, Ceylon and African teas - Builder’s tea is strong, milky and often sweet - Most UK tea bags contain CTC tea - Milk-first is cultural more than scientific - Many guests judge a café by its standard tea #### Earl Grey and flavoured teas Earl Grey is black tea flavoured with bergamot, a citrus fruit grown mainly in Calabria, southern Italy. It’s named after Charles Grey, 2nd Earl Grey, British Prime Minister in the 1830s, though the precise origin story is debated. Quality varies: good Earl Grey uses real bergamot oil or high-quality flavouring on decent tea, while cheap versions can taste soapy. Variations include Lady Grey (with additional citrus such as orange and lemon), Earl Grey Cream (with vanilla), and Russian Earl Grey (with additional citrus and lemongrass). Earl Grey is often drunk with lemon or a little milk, though milk can clash with the citrus for some palates. Other popular flavoured teas include jasmine green tea (scented with jasmine flowers), Lapsang Souchong (smoked over pinewood, polarising), and fruit or caramel-flavoured blacks. Flavoured teas are popular in afternoon tea menus, where guests enjoy variety. Store flavoured teas separately from unflavoured teas, as aromas migrate. Use dedicated teapots or clean them thoroughly to avoid flavours lingering. Check whether flavourings contain allergens. When describing them, mention whether the flavour is natural or added. Price flavoured teas similarly to other speciality teas. - Earl Grey is flavoured with bergamot - Named after the 2nd Earl Grey - Lady Grey adds extra citrus - Lapsang Souchong is smoked over pinewood - Store flavoured teas separately to avoid aroma transfer #### Assam, Darjeeling and Ceylon India and Sri Lanka produce some of the best-known black teas. Assam, in north-east India, grows the Camellia sinensis var. assamica plant in hot, low-lying plains, producing strong, malty, brisk teas that are the backbone of breakfast blends; ‘second flush’ Assam with golden tips is especially prized. Darjeeling, in the Himalayan foothills of West Bengal, grows mainly the smaller-leaf Chinese variety at high altitude, producing light, aromatic teas with muscatel character, often called the ‘champagne of teas’; first flush (spring) teas are fresh and floral, second flush (summer) are fuller and more muscatel. Darjeeling has protected geographical indication status. Nilgiri, in southern India, produces bright, fragrant teas good for iced tea. Ceylon tea from Sri Lanka varies by elevation: high-grown teas (such as Nuwara Eliya) are light and bright; mid-grown (Kandy) and low-grown (Ruhuna) teas are fuller and darker. Brewing: Assam and Ceylon take boiling water and milk well; Darjeeling is best brewed slightly cooler and shorter, often without milk. Offering a single-estate Darjeeling or Assam alongside your breakfast tea adds interest to an afternoon tea menu and allows upselling to tea enthusiasts. - Assam is malty and strong - Darjeeling is called the ‘champagne of teas’ - Darjeeling has protected geographical status - Ceylon tea varies by elevation - Darjeeling is often drunk without milk #### Loose leaf versus tea bags Tea bags are convenient, consistent and cheap, which is why most UK tea is sold that way. Traditional bags hold small leaf particles (fannings and dust) and CTC tea, which brew fast and strong but lack nuance. Pyramid or ‘tea temple’ bags made from mesh hold larger leaves and allow more room to expand, giving better flavour. Loose leaf tea offers more variety and quality, with whole or broken leaves that unfurl and release complex flavours, but it requires infusers, strainers or teapots with built-in filters, plus more staff time and cleaning. Costs per cup vary: good loose leaf can be economical because leaves can be re-steeped and portions controlled, but premium teas are pricier. Plastic in tea bags has been a concern; many UK brands have moved to plant-based materials such as PLA, which may need industrial composting. Check packaging claims. For cafés, a mix often works: quality bags or pyramids for speed and builder’s tea, loose leaf for speciality teas and afternoon tea service. Present loose leaf in clear glass teapots or with timers to show care. Train staff to weigh tea and use correct water temperatures. Explain the difference to guests confidently, without snobbery about tea bags. - Traditional bags use fannings and dust - Pyramid bags allow leaves to expand - Loose leaf offers more variety and quality - Many tea bags now use plant-based plastics like PLA - Mix bags and loose leaf for speed and quality #### Orthodox and CTC tea production Black tea is made in two main ways. Orthodox processing follows traditional steps: withering (reducing moisture), rolling (by hand or machine) to break cell walls and shape leaves, oxidation, and drying. It produces whole and broken leaf grades with complex flavours, used for speciality teas like Darjeeling and high-quality Assam. CTC (crush, tear, curl) processing, developed in the twentieth century, passes leaves through rollers with sharp teeth, producing small, uniform pellets that brew quickly into strong, dark, consistent tea. CTC dominates tea bag production and breakfast blends. Leaf grades include OP (orange pekoe, whole leaf), FOP (flowery orange pekoe, with tips), TGFOP (tippy golden flowery orange pekoe), BOP (broken orange pekoe), fannings and dust. ‘Orange pekoe’ has nothing to do with oranges; it’s a grading term. Grades describe leaf size and appearance, not necessarily flavour quality. Green and white teas are processed differently, with heat applied to stop oxidation early (steaming in Japan, pan-firing in China). Understanding processing helps staff explain why some teas brew faster or taste stronger, and why expensive teas aren’t just ‘better tea bags’. It also helps with buying, as you can ask suppliers informed questions about grades and origins. - Orthodox tea is rolled and oxidised traditionally - CTC means crush, tear, curl - CTC dominates tea bags - Orange pekoe is a grading term, not a flavour - Grades describe leaf size and appearance #### Tea service equipment Good tea service needs the right kit. Teapots: ceramic or porcelain pots retain heat well; glass pots show off leaves and colour; cast iron pots retain heat but are heavy and need careful drying. Infusers and strainers: built-in infusers or removable baskets allow leaves to be taken out after brewing, preventing over-steeping; tea socks and paper filters offer disposable options. Gaiwans and small clay pots suit gongfu brewing of oolong and pu-erh. Timers: sand timers at the table help guests know when tea is ready. Water: a boiler with variable temperature, or separate kettles, lets you brew green, white and oolong teas at lower temperatures. Cups and saucers, milk jugs, sugar bowls or sachets, lemon slices and tea strainers complete the set. Tea cosies keep pots warm for longer at the table. Hot water jugs for top-ups add value and reduce complaints. Keep equipment clean: tea stains build up inside pots and cups; soak periodically in suitable cleaning solution. Dishwashers can damage some pots and cast iron. Choose sturdy pieces for busy service, and keep spares. Presentation matters, especially for afternoon tea, where tableware sets the tone. Budget for breakages; teapot lids are a common casualty. - Removable infusers prevent over-steeping - Glass pots show leaves and colour - Sand timers help guests know when tea is ready - Offer hot water top-ups - Budget for breakages, especially lids #### Iced tea and cold brew tea Iced tea is popular in summer and adds variety to café menus. Methods: brew hot tea at double strength and pour over ice (the ‘Japanese’ method for tea); brew normal-strength tea, cool and refrigerate; or cold brew tea by steeping leaves in cold water in the fridge for several hours, typically six to twelve, which gives smooth, sweet tea with less bitterness. Good teas for iced tea include Ceylon, Nilgiri, Darjeeling, green teas, oolongs, hibiscus and fruit blends. Sweetened iced teas use sugar syrup, as granulated sugar doesn’t dissolve in cold liquid. Flavours include lemon, peach, mint and berries. Sparkling iced teas and tea-based mocktails can be signature drinks. Food safety: brewed tea stored for long periods can grow bacteria; make batches regularly, store covered in the fridge, label with times, and discard after a set time (often within a day or two). Clean dispensers and urns thoroughly. Ice must be made from potable water and handled with scoops, never glasses. Price iced teas competitively with soft drinks; margins are high because tea is cheap. Check the Soft Drinks Industry Levy if you bottle sweetened drinks for retail. Serve in clear glasses or cups to show colour. - Cold brew tea steeps for several hours in the fridge - Use sugar syrup for sweetened iced tea - Label and discard brewed tea after a set time - Handle ice with scoops, never glasses - Iced tea margins are high #### Tea storage and freshness Tea is less perishable than coffee but still loses quality if stored badly. Store loose leaf and bags in airtight containers, away from light, heat, moisture and strong odours; tea readily absorbs smells, so never store it near spices, coffee or cleaning products. Green and white teas are most delicate and lose freshness within months; some suppliers recommend refrigerating opened matcha or delicate green teas, but avoid repeated condensation. Black teas and oolongs last longer, often a year or two when stored well. Pu-erh is designed to age but needs some airflow and stable humidity. Buy quantities you can use within a reasonable time, and rotate stock first in, first out. Label containers with tea name, purchase date and brewing instructions. Opaque tins are better than clear jars on sunny shelves. For display, keep a small amount in clear jars for guests to see and smell, but store the main stock properly. Check best-before dates and discard stale tea; it tastes flat and dusty. When training staff, let them smell fresh and stale tea side by side; the difference is obvious and helps them understand why storage matters. Good storage protects the value of expensive speciality teas. - Store tea airtight, away from light and odours - Green and white teas lose freshness fastest - Black teas and oolongs last longer - Use opaque tins rather than clear jars - Rotate tea stock first in, first out #### Tea menu design A good tea menu balances choice with simplicity. Most cafés need a strong breakfast tea, Earl Grey, a green tea, peppermint, chamomile and a fruit blend; add decaf breakfast tea and rooibos for caffeine-free guests. Speciality cafés and afternoon tea venues may add a single-estate Darjeeling, a jasmine green, an oolong, a pu-erh, a white tea and a seasonal blend. Group teas by type (black, green, oolong, herbal) or by mood (strong, light, floral, caffeine-free), with short tasting notes and whether milk is recommended. Include brewing times or bring timers to the table. Show caffeine status clearly. Avoid overwhelming guests with dozens of options; more choice slows ordering and increases stock waste. Choose a reputable supplier with consistent quality and good support; many UK tea companies provide menu cards and training. Price tiers: a base price for standard teas and a premium for speciality teas. Consider tea pairings with cakes and pastries. Train staff to recommend teas based on guest preferences, such as suggesting Assam for someone who likes strong tea or jasmine for someone who wants something light. Review sales data and remove slow-selling teas. Rotate seasonal teas to keep interest. - Cover breakfast, Earl Grey, green, mint, chamomile and fruit - Show caffeine status clearly - Group teas by type or mood - Avoid overwhelming choice - Remove slow-selling teas #### Pricing tea Tea has a very low ingredient cost per cup, often only a few pence for a quality tea bag, more for premium loose leaf, so gross profit on tea is usually very high. But pricing should reflect more than ingredients: staff time, teapots, washing, milk, sugar, lemon, hot water top-ups, and the seat a guest occupies. Many UK cafés price a pot of standard tea slightly below a latte, and speciality teas around the same or higher. Charging too little undervalues tea and makes it seem an afterthought; charging too much for a bag in a mug causes resentment. Pots for one or two, and hot water top-ups, offer value. Premium teas with re-steeping can justify higher prices. For afternoon tea, tea is usually included and may be unlimited; factor this into package pricing. Takeaway tea is commonly cheaper than sit-in pots; note that VAT applies to hot drinks whether eaten in or taken away. Some cafés charge extra for plant milk in tea, but many don’t; be consistent with your coffee policy. Review tea prices when you update coffee prices, and check competitors. Promote tea pairings with cakes to increase average spend. Tea is often ordered by older guests and families, an important part of many cafés’ customer base. - Tea ingredient cost is often a few pence per cup - Price tea for service, not just ingredients - Hot drinks are standard-rated for VAT, eat-in or takeaway - Afternoon tea packages often include unlimited tea - Promote tea and cake pairings ### Afternoon Tea #### Cream tea A cream tea is scones served with clotted cream and jam and a pot of tea. It is strongly associated with Devon and Cornwall, and the rival ‘correct’ order is part of the fun: in Devon, cream first then jam; in Cornwall, jam first then cream. Neither is wrong, and staff should never correct a guest. Clotted cream is made by heating full-cream milk or cream and letting it cool slowly, so a thick, golden crust forms; Cornish clotted cream has protected designation of origin status and must be made in Cornwall from Cornish milk with a minimum fat content. Serve scones warm or freshly baked, with generous portions of cream and jam in pots or ramekins. Strawberry jam is traditional; raspberry also common. A cream tea is a high-margin, simple offer for cafés, tea rooms and hotels, especially in tourist areas. Price it as a package. Offer vegan and gluten-free versions with appropriate scones, plant-based cream alternatives and jam, labelled clearly. Allergens: scones contain gluten, milk and often egg; clotted cream contains milk. If you sell takeaway cream tea boxes, ensure cream is kept chilled and labelled correctly. Cream tea is a classic British experience that tourists actively seek out. - Devon puts cream first, Cornwall jam first - Cornish clotted cream has PDO status - Clotted cream is made by slow heating and cooling - Never correct a guest’s order of cream and jam - Cream teas are high-margin packages #### Scones Scones are central to cream tea and afternoon tea. A classic recipe uses self-raising flour (or plain flour with baking powder), butter, sugar, milk and sometimes egg. The method: rub cold butter into flour until it resembles breadcrumbs, add sugar, then mix in milk (and egg) quickly to form a soft dough; avoid overworking, which makes scones tough. Pat the dough to around 2.5 centimetres thick, cut with a sharp round cutter pressed straight down (twisting seals edges and stops them rising evenly), brush tops with egg wash or milk, and bake in a hot oven until risen and golden. Variations include fruit (sultanas), cheese, and seasonal flavours. Scones are best eaten the day they’re baked; many tea rooms bake them fresh each morning or bake in batches through the day. Freezing unbaked scones and baking to order helps reduce waste. Pronunciation (‘scon’ or ‘scone’) divides the nation; again, never correct guests. Serve warm, ideally split by hand, with clotted cream and jam. Gluten-free and vegan scones are possible but need recipe testing. Allergens include gluten, milk and egg. Record recipes and portion sizes for consistency and costing, and track how many you sell daily to bake the right amount. - Rub cold butter into flour - Avoid overworking the dough - Cut straight down without twisting - Scones are best on the day of baking - Freeze unbaked scones to reduce waste #### Afternoon tea sandwiches Finger sandwiches are the savoury base of afternoon tea. Classics include cucumber (with butter or cream cheese), egg and cress (or egg mayonnaise), smoked salmon with cream cheese, ham and mustard, and coronation chicken. Use soft white and brown bread, thinly sliced, with crusts removed for neat edges. Butter the bread to the edges to create a moisture barrier. Cut into fingers, triangles or squares. Prepare close to service and keep covered and chilled to prevent drying out; cucumber sandwiches go soggy if made too far in advance, so salt and drain cucumber first or assemble later. Sandwich fillings are high-risk foods for food safety: keep chilled at 8°C or below (the legal maximum in England, Wales and Northern Ireland for many chilled foods, with 5°C commonly targeted), and follow your food safety management system. Offer vegetarian, vegan and gluten-free sandwiches, clearly labelled and prepared carefully to avoid cross-contamination. Allergens: gluten, eggs, milk, fish, mustard and sesame (in some breads) are common. Quantities: typically around four or five finger sandwiches per person. Present them neatly on the bottom tier of the stand. Seasonal fillings add interest. Cost each sandwich carefully, as fillings like smoked salmon are expensive. - Classic fillings include cucumber and egg and cress - Butter to the edges to prevent sogginess - Keep sandwiches chilled at 8°C or below - Offer clearly labelled dietary versions - Around four or five finger sandwiches per person #### Afternoon tea sweets and patisserie The top tier of afternoon tea is cakes and pastries: miniature Victoria sponge, lemon drizzle, éclairs, macarons, fruit tarts, mousse cups, brownies and seasonal creations. Hotels and high-end venues often create elaborate patisserie, while tea rooms favour homemade cakes. Balance flavours and textures: something fruity, something chocolatey, something creamy and something light. Size matters: pieces should be two or three bites, so guests can try everything. Make components ahead (sponges, pastry shells, fillings) and assemble on the day. Keep cream-based items chilled. Allergens are numerous: gluten, eggs, milk, nuts (especially in macarons, which use almond flour), soy and sulphites in dried fruit. Provide allergen information for every item. Dietary versions (vegan, gluten-free) need separate recipes and careful preparation. Present attractively on the top tier or on separate plates. Themed afternoon teas (seasonal, film, fashion or literary themes) often focus on the sweet tier for creativity. Consider making some items in-house and buying others from specialist suppliers to save time. Costs can be high, so plan portions carefully. Ask guests for feedback and rotate items to keep regulars interested. - Pieces should be two or three bites - Balance fruity, chocolatey, creamy and light - Macarons usually contain almond flour - Make components ahead and assemble on the day - Themed teas focus creativity on the sweet tier #### Afternoon tea bookings and pricing Afternoon tea is a popular experience for birthdays, hen parties, gifts and tourists, and is usually booked in advance. Use a booking system to manage tables, deposits and dietary requirements. Ask for dietary needs and allergies at booking and confirm them before the visit. Deposits or card details help reduce no-shows; communicate cancellation terms clearly and fairly, and follow consumer law on deposits and charges. Price per person, with options such as champagne or sparkling wine afternoon tea, gin afternoon tea, or children’s afternoon tea. Gift vouchers are a major revenue source; manage them carefully with expiry dates and terms, and record liabilities in your accounts. UK prices vary widely, from modest tea-room offers to luxury hotel experiences costing far more. Costs include food, tea, labour (preparation is time-consuming) and tableware. Calculate gross profit carefully; afternoon tea can be profitable but labour-intensive. Offer takeaway boxes for leftovers, and consider sustainability. Time slots (for example 90 minutes) help manage table turns. Staff should explain the stand and tea options and offer refills. Upsells include extra drinks, sparkling wine and retail items such as jams or tea. Photograph your afternoon tea well; it sells on social media. - Ask for allergies at booking and confirm before the visit - Deposits reduce no-shows - Gift vouchers are a major revenue source - Time slots manage table turns - Afternoon tea is labour-intensive #### Champagne and themed afternoon teas Adding a glass of champagne, sparkling wine or a cocktail to afternoon tea increases the price and perceived luxury. Sparkling afternoon tea typically includes one glass; offer top-ups or upgrades. Alcohol sales require a premises licence and a designated premises supervisor under the Licensing Act 2003 in England and Wales (with separate systems in Scotland and Northern Ireland); ensure you’re licensed and staff follow age verification policies. Offer alcohol-free alternatives such as sparkling tea or mocktails. Themed afternoon teas, such as seasonal (Christmas, Easter, summer), literary, film or fashion themes, attract publicity and social media attention. Use theme-related names, colours and decorations, but avoid using trademarked characters or brands without permission; partnerships with brands or attractions can help. Children’s afternoon teas with playful items are popular in family venues. Plan themes well in advance: menu development, costing, allergen information, staff training and marketing. Themes should be achievable in your kitchen; complicated decorations slow production. Track sales and feedback to decide which themes to repeat. Limited-time themes create urgency, while a reliable classic afternoon tea remains the backbone of bookings. - Alcohol sales need a premises licence and a DPS in England and Wales - Offer alcohol-free alternatives - Avoid trademarked characters without permission - Plan themes well in advance - Keep a classic afternoon tea as the backbone #### Dietary afternoon teas Guests increasingly request vegan, vegetarian, gluten-free, dairy-free and other dietary versions of afternoon tea. Each needs a full alternative menu, not just removing items. Vegan afternoon tea uses plant-based sandwiches (for example, hummus and roasted vegetables), vegan scones with plant-based cream and jam, and vegan cakes. Gluten-free versions need gluten-free bread, scones and cakes, prepared to avoid cross-contamination; if you use a ‘gluten-free’ claim, foods must contain 20 parts per million of gluten or less, so careful sourcing and preparation matter. Dairy-free requires avoiding milk in all components, including butter and chocolate. Make sure staff understand the difference between preferences and allergies, and handle allergy orders with strict procedures. Ask for dietary requirements at booking to prepare in advance. Clearly label items on the stand or provide a separate stand. Charge the same price unless costs differ significantly; guests dislike paying more for dietary requirements. Test recipes thoroughly; dietary items should taste as good as standard items. Pre-made dietary products are available from specialist suppliers, which can save time and reduce risk. Good dietary afternoon teas attract loyal customers and positive reviews. - Create full alternative menus for dietary needs - ‘Gluten-free’ means 20ppm gluten or less - Ask for dietary needs at booking - Label or separate dietary items clearly - Avoid charging more where possible ### Hot Chocolate #### Drinking chocolate types Hot chocolate on UK menus ranges from sweet cocoa powder drinks to rich, melted-chocolate experiences. Cocoa powder is ground cocoa solids with most of the cocoa butter removed; ‘Dutch-processed’ cocoa is alkalised to reduce acidity and darken colour. Drinking chocolate powders mix cocoa with sugar, and often milk powder and flavourings; they’re quick and consistent but can be very sweet. Chocolate flakes, drops or callets (small pieces of real chocolate) melted into milk give a richer, thicker drink with genuine cocoa butter. Percentages indicate cocoa content: a 70 per cent chocolate contains 70 per cent cocoa solids and cocoa butter, with the rest mostly sugar. Speciality chocolate companies, including UK bean-to-bar makers, supply high-quality drinking chocolates; some cafés make their own blends. Hot chocolate quality depends on chocolate choice, milk, temperature and mixing. Choose a product that suits your audience; a sophisticated dark hot chocolate impresses adults, while children often prefer sweeter milk chocolate. Many cafés offer both. Check allergens: chocolate may contain milk, soya and traces of nuts. Vegan options need dairy-free chocolate. Cost per serving varies widely, from pennies for powder to more for quality chocolate; price accordingly. - Cocoa powder has most cocoa butter removed - Dutch-processed cocoa is alkalised - Callets are small pieces of real chocolate - Percentage indicates cocoa content - Offer both dark and sweeter options #### Making hot chocolate on the bar Good hot chocolate needs technique as much as ingredients. With powder: add the measured powder to the cup, mix with a little hot water or steamed milk to form a smooth paste, then add steamed milk while stirring. With chocolate callets: melt them in a small amount of hot water or milk, or steam them directly in the milk jug, whisking or swirling to dissolve fully; clean the steam wand immediately, as chocolate burns onto it. Some cafés use dedicated hot chocolate machines that stir and heat chocolate continuously, useful for high volumes and thick European-style chocolate. Temperature: around 60 to 65°C keeps sweetness and prevents a skin forming. Foam: lightly textured milk gives a silky drink; heavy foam dilutes chocolate flavour. Toppings: whipped cream, marshmallows, chocolate shavings, cocoa dusting, or flavoured syrups such as orange or mint. Plant milks: oat milk works well; almond can be thin; coconut adds richness. Consistency: measure chocolate and milk by weight or volume in recipes. Clean jugs thoroughly afterwards, as chocolate residue can contaminate other drinks and is an allergen risk for milk-free guests. Hot chocolate is popular in winter, with children and in the evening; promote it during cold snaps. - Make a smooth paste before adding milk - Clean steam wands immediately after chocolate - Aim for around 60–65°C - Measure chocolate and milk for consistency - Promote hot chocolate in cold weather #### European-style and speciality hot chocolate European-style hot chocolate, common in Spain, Italy and France, is thick, rich and intense. Spanish chocolate a la taza is thickened (often with cornflour) and served with churros for dipping. Italian cioccolata calda is similarly thick, almost like a pudding. French chocolat chaud is rich and creamy, often made with real chocolate and milk or cream. These styles use high-quality chocolate and sometimes thickeners, served in small cups. Single-origin drinking chocolates, made from beans from specific countries such as Madagascar, Ecuador or Peru, offer distinct flavours like red fruit or floral notes, appealing to chocolate enthusiasts. Spiced hot chocolates, inspired by Mesoamerican traditions where cacao was first consumed as a drink, use chilli and cinnamon. Ceremonial cacao, sold as a wellness product, is minimally processed cacao paste; avoid making unauthorised health claims about it. Serving speciality hot chocolate can differentiate your café, especially during winter. Price premium versions higher and explain them on the menu. Pair them with pastries, such as churros or biscotti. Check allergens: thickeners may contain gluten, and chocolate may contain milk. Thick hot chocolate machines help maintain consistent texture during busy periods. - Spanish hot chocolate is thick and served with churros - Italian cioccolata calda is pudding-like - Single-origin chocolates have distinct flavours - Cacao was first consumed as a drink in Mesoamerica - Avoid unauthorised health claims about ceremonial cacao ### Café Economics #### Cost per cup Knowing your cost per cup is basic café economics. Calculate it by adding the cost of each ingredient and consumable. For a latte: coffee (dose in grams times cost per gram, including waste from purging and dialling in), milk (volume times cost per litre, plus waste), cup, lid, sleeve, stirrer, napkin, and any syrup or topping. For sit-in drinks, add an allowance for dishwashing and breakages. For example, an 18-gram dose from coffee costing around £20 per kilo is about 36 pence; 200 millilitres of milk at around £1 per litre is about 20 pence; a takeaway cup and lid may add 10 to 20 pence. Plant milks cost more. The total ingredient and packaging cost for a latte might be somewhere around 70 pence to £1 or more, depending on suppliers. That’s before labour, rent, energy and other overheads. Update costs whenever supplier prices change. Use a spreadsheet or POS with recipe costing to calculate gross profit per drink. Knowing costs helps set prices, decide on promotions and identify which drinks are most profitable. Many owners are surprised by how much milk and packaging contribute. Share cost information with staff to encourage portion control and waste reduction. - Include waste in coffee and milk costs - Add cups, lids, sleeves and napkins - An 18g dose at £20/kg costs about 36p - Update costs when supplier prices change - Share costs with staff to cut waste #### Gross profit targets for cafés Gross profit (GP) is sales minus the cost of ingredients and packaging, usually expressed as a percentage of sales (excluding VAT). Coffee and tea typically deliver very high GP, often 70 to 85 per cent or more; food usually lower, perhaps 55 to 70 per cent, depending on whether it’s made in-house or bought in. Retail products like bags of coffee or bottled drinks often have lower margins. A café’s overall GP depends on its sales mix: a coffee-heavy café has higher GP than one selling lots of bought-in sandwiches. However, high GP alone doesn’t guarantee profit; labour and rent are major costs. Calculate GP for each product and category, and monitor actual GP against theoretical GP (based on recipes); a gap suggests waste, theft, over-portioning or incorrect pricing. Remember VAT: prices displayed include VAT where applicable, but GP calculations should use net sales. Food items sold cold for takeaway may be zero-rated, while eat-in food and hot takeaway food are standard-rated, which affects net sales. Review GP monthly and adjust pricing, portion sizes or suppliers when it slips. Set GP targets for each category, and include them in staff training and manager KPIs. - Coffee and tea often achieve 70–85% GP - Food GP is usually lower - Calculate GP on net sales excluding VAT - Compare actual GP with theoretical GP - Review GP monthly #### Pricing coffee in the UK Setting coffee prices means balancing costs, competition and customer expectations. Start with costs: aim for a target GP, then consider labour, rent and overheads. Compare with local competitors, including chains and independents, but don’t simply copy; quality, location and experience justify differences. Consider psychological pricing: prices ending in 0 or 5 pence are easier at the till; small increases (for example 10 to 20 pence) are less noticeable than big jumps. Size pricing: the price difference between sizes should reflect extra milk and shots but also encourage upsizing. Add-ons: extra shots, syrups and plant milks add revenue, though charging for plant milk is increasingly unpopular. Review prices at least annually and when costs rise sharply. Communicate increases calmly; most regulars accept reasonable rises, especially with good service. Loyalty schemes can soften increases. Avoid constant discounting, which erodes perceived value. Remember that VAT applies to hot drinks whether eat-in or takeaway, so takeaway coffee isn’t cheaper to provide in tax terms. Specialty cafés often charge more for single-origin filter or premium drinks. Monitor sales after price changes to see whether volumes fall; small decreases may be offset by higher margins. - Set prices from costs and target GP - Compare competitors but don’t simply copy - Small, regular increases are less noticeable - Hot drinks are standard-rated for VAT - Monitor volumes after price changes #### VAT basics for cafés VAT is complex for cafés, and mistakes are costly. In the UK, the standard rate is 20 per cent. Hot drinks are standard-rated, whether eaten in or taken away. Food eaten on the premises (including seating areas shared with other businesses) is standard-rated as catering. Cold takeaway food is generally zero-rated, but there are exceptions: confectionery, crisps, ice cream, soft drinks and some other items are standard-rated even when taken away. Hot takeaway food is standard-rated; the rules about whether food is ‘hot’ depend on whether it’s heated to be eaten hot, kept hot, or advertised as hot. Bakery items cooling from the oven can be zero-rated if they’re sold to be eaten cold, such as freshly baked bread. Mixed transactions need careful allocation. Your POS system should record eat-in and takeaway sales separately so the right VAT rate is applied. VAT registration is required when taxable turnover exceeds the threshold (£90,000 from April 2024). Some small businesses use the flat-rate scheme. Rules change, so check HMRC guidance or consult an accountant, especially when setting up. Display prices including VAT to consumers. Train staff to ask ‘eat in or takeaway?’ and record it correctly. - Hot drinks are standard-rated at 20% - Eat-in food is standard-rated - Most cold takeaway food is zero-rated, with exceptions - VAT registration threshold is £90,000 from April 2024 - Record eat-in and takeaway sales separately #### Break-even and covers Break-even is the point where sales cover all costs. To calculate it, add your fixed costs per period (rent, rates, insurance, salaries, loan repayments, utilities, subscriptions) and divide by your average contribution per customer (average spend minus variable costs such as ingredients and packaging). For example, if fixed costs are £10,000 a month and average contribution is £3 per customer, you need around 3,333 customers a month, or about 128 a day over 26 trading days, just to break even. Every customer after that contributes to profit. This simple calculation shows how important average spend and volume are, and helps when deciding opening hours, staffing and pricing. Labour costs are partly variable: extra staff for busy periods increase costs, so model different scenarios. Seasonality matters: a café that breaks even in winter makes good profit in summer, or vice versa. Use POS data to track daily customers (covers or transactions) and average transaction value. Review monthly and compare with forecasts. If you’re consistently below break-even, consider reducing costs, increasing prices, boosting average spend through food and upselling, or changing opening hours. Banks and investors will ask for break-even analysis in business plans. - Break-even = fixed costs ÷ average contribution - Track daily transactions and average spend - Model labour as partly variable - Seasonality shifts break-even - Banks expect break-even analysis in plans #### Average transaction value Average transaction value (ATV), or average spend, is total sales divided by number of transactions. Raising it is often easier than finding more customers. Methods: offer food with drinks (‘would you like a pastry with that?’), meal deals (coffee and cake), upsizing, add-ons (extra shot, syrup), retail items (bags of coffee, merchandise), and premium options (single-origin filter, speciality drinks). Displays matter: a well-stocked, attractive cake counter at the till encourages impulse buys. Train staff to suggest items naturally, not pushily, and to recommend products they genuinely like. Track ATV by time of day: morning commuters spend less, brunch and afternoon customers more. Set targets and incentives, such as team rewards for hitting ATV goals, but avoid pressure that annoys guests. Monitor attachment rate (percentage of transactions including food). Loyalty schemes can encourage additional purchases. Menu design highlights high-margin items. Seasonal specials and limited editions create urgency. Even small increases in ATV, such as 20 pence per transaction, can significantly boost annual revenue in a busy café. Combine ATV analysis with GP so you’re increasing profitable sales, not just volume of low-margin items. - ATV = total sales ÷ transactions - Food attachment is the biggest ATV lever - Displays at the till drive impulse buys - Track ATV by time of day - Small ATV increases add up over a year #### Loyalty schemes Loyalty schemes reward regular customers and encourage repeat visits. Traditional stamp cards (buy nine, get the tenth free) are cheap and simple, but easy to lose or forge. Digital schemes via apps or POS systems track purchases automatically, offer personalised rewards, and collect data on customer habits; some integrate with mobile ordering. Considerations: cost of rewards (a free coffee every ten is effectively a 10 per cent discount for loyal customers), administration, data protection (collecting customer data means complying with UK GDPR and the Data Protection Act 2018, including clear privacy information and consent for marketing), and integration with your systems. Rewards can include free drinks, discounts, birthday treats, early access to new products or exclusive events. Avoid making schemes too complicated. Promote them at the till and on receipts. Track redemption rates and changes in visit frequency to see if the scheme works. Loyalty schemes shouldn’t replace good service and quality; they reinforce existing loyalty rather than create it. Independent cafés can also join local loyalty networks or apps shared with other businesses. Consider rewarding behaviours you want, such as using reusable cups or visiting during quiet periods. - Buy-nine-get-one-free is effectively a 10% discount - Digital schemes collect useful customer data - Customer data must comply with UK GDPR - Track redemption and visit frequency - Reward behaviours like reusable cups #### Labour costs and rota planning Labour is usually a café’s largest cost after ingredients, and sometimes the largest overall. Labour cost percentage (wages, employer’s National Insurance and pension contributions, divided by net sales) is a key metric; many cafés aim for somewhere around 25 to 35 per cent, though it varies by format. Employer National Insurance rose in April 2025, increasing costs for many hospitality businesses; factor current rates into budgets. National Minimum Wage and National Living Wage rates rise each April. Rota planning: use POS data to match staffing to demand, with more staff during peaks and fewer during quiet periods. Split shifts and part-time staff provide flexibility, but staff need fair, predictable hours to stay. Avoid overstaffing in quiet periods and understaffing during rushes, which damages service and stresses staff. Cross-train staff so they can cover multiple roles. Track productivity, such as sales per labour hour. Remember legal requirements: rest breaks, holiday pay (including for irregular-hours workers), working time limits for young workers, and accurate payroll records. Rota software can help forecast and manage costs. Labour is also an investment: well-trained, happy staff increase sales and reduce turnover costs. - Labour is often 25–35% of sales - Employer National Insurance rose in April 2025 - Minimum wage rates rise each April - Use POS data to match staffing to demand - Track sales per labour hour #### Rent, location and footfall Location makes or breaks a café. High-footfall locations (stations, high streets, office districts) bring customers but command high rents; quieter locations are cheaper but rely on destination appeal or local loyalty. Rent as a percentage of sales is a useful metric; many hospitality businesses aim to keep rent and rates somewhere around 10 to 15 per cent of turnover, though it varies. Assess footfall by counting passers-by at different times, observing competitors, and checking nearby offices, schools, residences and transport. Consider visibility, access, parking, outdoor seating potential and the type of footfall (commuters want speed; shoppers and families want seating and food). Lease terms matter: length, break clauses, rent reviews, repair obligations, service charges and permitted use; get legal advice before signing. Business rates add significantly to occupancy costs; check the rateable value and any reliefs available, such as small business rate relief or sector reliefs, which change with government policy. Planning permission may be needed for change of use or outdoor seating, and a pavement licence from the local authority for tables outside. Fit-out costs vary greatly; budget carefully and include contingencies. - High footfall locations command high rents - Rent and rates are often aimed at 10–15% of turnover - Count footfall at different times - Get legal advice on lease terms - Pavement licences are needed for outside tables #### Food offer in a coffee shop Food increases average spend and attracts customers at different times of day, but it adds complexity: equipment, storage, staff skills, waste and food safety. Options: buy in pastries and cakes from wholesalers or local bakeries (simple, consistent, lower margin), bake from frozen (fresh-baked aroma, good margin, needs ovens and freezer space), make in-house (best margins and uniqueness but labour-intensive), or offer a full kitchen menu (brunch, lunch) with higher sales but much higher costs and complexity. Popular café foods include croissants, pain au chocolat, cinnamon buns, banana bread, toasties, sandwiches, salads, soups and brunch dishes. Pair food with drinks through meal deals. Food safety: register as a food business with your local authority at least 28 days before trading; follow a food safety management system based on HACCP principles; train staff; and manage allergens. Waste management: track what sells and what is thrown away; reduce orders, adjust bake schedules, or offer discounts near closing via apps such as Too Good To Go. Food quality affects reputation and reviews. Display food attractively and label clearly with prices and allergen information. Food Hygiene Rating Scheme scores are public and influence customers. - Food increases average spend - Bake-from-frozen gives fresh aroma and good margin - Register as a food business 28 days before trading - Use HACCP-based food safety management - Track waste and adjust ordering #### Food hygiene ratings for cafés The Food Hygiene Rating Scheme, run by local authorities with the Food Standards Agency, rates food businesses in England, Wales and Northern Ireland from 0 to 5 after inspections, based on hygienic handling of food, the condition of premises and facilities, and food safety management (including documentation). Scotland runs the Food Hygiene Information Scheme with ‘Pass’ or ‘Improvement Required’ results. Display of ratings is mandatory in Wales and Northern Ireland, but voluntary in England (though many businesses display them proudly, and the rating is published online regardless). A low rating damages reputation and can reduce trade, as many customers check ratings online. To achieve 5: keep premises clean and in good repair; control temperatures for chilled and hot foods and record them; manage allergens; ensure staff training and hand washing; control pests; and maintain a food safety management system such as the FSA’s Safer Food, Better Business pack. For coffee shops, inspectors look at milk storage temperatures, cleaning of milk equipment, hand-washing facilities at the bar, and cleaning schedules. If you disagree with a rating, there are appeal and right-to-reply procedures, and you can request a re-inspection after making improvements. - Ratings run from 0 to 5 - Scotland uses Pass or Improvement Required - Display is mandatory in Wales and Northern Ireland - Safer Food, Better Business is the FSA’s pack - You can request re-inspection after improvements #### Laptop workers and dwell time Many cafés attract remote workers and students who stay for hours with laptops. They bring steady trade during quiet periods but can occupy tables during peaks, reducing table turnover and sales. Policies vary: some cafés welcome laptops all day, others restrict them at lunchtime or weekends, designate laptop areas, limit Wi-Fi time, cover sockets, or ask for minimum spend per hour. Calculate the value of a table: if a table could serve several lunch customers in two hours but is occupied by one person with one coffee, that’s lost revenue. However, laptop workers often become loyal regulars, and their presence makes cafés feel busy and welcoming. Communicate policies politely and clearly with signs and staff explanations. Offer co-working packages, such as day passes including drinks and snacks, if you have space. Wi-Fi quality and power sockets are draws; choose whether to promote them. Design seating to support your strategy: bar seating for solo workers, larger tables for groups. Monitor sales by time of day and table usage to decide. Balance hospitality with business needs; a friendly approach keeps goodwill, whereas strict, unexplained rules can lead to negative reviews. - Laptop workers bring trade in quiet periods - They can reduce table turnover at peaks - Some cafés restrict laptops at busy times - Co-working day passes monetise space - Communicate policies politely and clearly #### Opening hours and trading patterns Choosing opening hours involves balancing demand, staff costs and customer expectations. Most UK cafés see a morning rush (commuters), a mid-morning lull, a lunch peak and an afternoon tail-off, with variations by location: office areas are busy on weekdays and quiet at weekends; high streets and parks are busy at weekends; tourist areas have seasonal peaks. Use POS data to analyse sales by hour and day. Opening an hour earlier may capture commuters; closing earlier may save labour when sales are low. Consider evening trade: some cafés add wine, beer or events, which may need licensing changes. Weather affects trade: sunny weekends boost parks and outdoor seating; rainy days push people indoors. Bank holidays and school holidays change patterns. Opening hours should be consistent and clearly displayed online (Google Business Profile, social media, website) and on the door; inconsistent hours frustrate customers. Test changes for a few weeks and monitor results. Remember that staff need time before opening and after closing for set-up and cleaning. Seasonal hours, such as longer summer opening, may suit some locations. Be cautious about late opening without demand; it can cost more than it earns. - Analyse sales by hour and day from POS data - Office areas are quiet at weekends - Weather strongly affects trade - Keep opening hours consistent online and on the door - Test changes for a few weeks #### Weather, seasons and café sales Café sales swing with weather and seasons. Cold, wet weather boosts hot drinks, soups and comfort food; hot weather increases iced drinks, cold brew, smoothies and ice cream while potentially reducing hot drink sales. Outdoor seating drives summer trade but sits empty in winter unless covered and heated. School holidays change patterns: family areas get busier, office areas quieter. The run-up to Christmas brings shoppers and festive drinks; January is often slow, as customers cut spending. Plan for seasonality: adjust menus, staffing and stock orders; launch seasonal specials; promote indoor comfort in winter and outdoor seating in summer. Use weather forecasts to adjust daily orders and staffing, such as ordering more ice and milk for iced drinks before a heatwave. Track sales against weather to learn patterns. Build cash reserves in busy months to cover slow months, and negotiate flexible terms with suppliers if possible. Marketing can smooth troughs: events, loyalty promotions and new menus during quiet periods. Consider seasonal retail items, such as gift boxes and coffee bags for Christmas. Accept that some months will be slower and plan finances accordingly; cash flow management is critical in hospitality. - Cold weather boosts hot drinks and soups - Heatwaves increase iced drink demand - January is often a slow month - Use forecasts to adjust orders and staffing - Build cash reserves in busy months #### Retail coffee sales Selling retail coffee bags, brewing equipment and merchandise adds revenue and builds brand loyalty. Retail bags from your roaster can be bought wholesale and sold at retail prices; margins vary, often lower than drinks but still useful, and there’s no labour for preparation. Grinding beans on request for customers adds value. Equipment such as V60s, AeroPresses, cafetières, grinders and scales sell well, especially at Christmas. Merchandise (branded cups, T-shirts, tote bags) promotes your brand. Subscriptions, where customers receive regular deliveries of coffee, provide recurring revenue; they require packaging, postage and online sales systems. Display retail items attractively near the till and train staff to recommend them, for example suggesting a bag of the coffee a customer enjoyed. Stock management is important: retail coffee has a shelf life, so order quantities you can sell within weeks. Check labelling requirements are met by suppliers. Consider online sales via your website, but factor in time and costs. Retail can be a significant revenue stream during quiet periods or when the café is closed. Offer gift cards and gift packs for holidays. Track retail sales separately in the POS to measure performance. - Retail bags add revenue without preparation labour - Brewing equipment sells well at Christmas - Subscriptions provide recurring revenue - Order retail coffee to sell within weeks - Track retail sales separately #### Waste tracking in the café Waste is lost profit. Common café waste includes unsold food, spoiled milk, stale coffee, incorrect drinks, purged coffee, broken crockery and excess packaging. Tracking waste helps identify problems and save money. Keep a waste log at the bar and kitchen, recording item, quantity, reason and cost. Review it weekly with staff. Solutions: adjust food orders and bake schedules based on sales data; use first-in, first-out stock rotation; train staff to measure milk and avoid over-steaming; reduce remakes by improving order accuracy; use leftovers creatively (for example, day-old pastries as bread pudding, if safe); offer end-of-day discounts or use surplus-food apps; donate surplus food to charities where food safety rules allow. Waste segregation is also legally required: business food waste and recyclables must be separated for collection in Scotland and Wales, and England’s Simpler Recycling rules require most businesses to separate food waste and dry recyclables, with micro-firms given extra time. Recycling coffee grounds and cups reduces environmental impact. Reducing waste improves GP, sustainability credentials and staff engagement. Set waste reduction targets and celebrate improvements. Even small reductions add up significantly over a year. - Keep a waste log with item, reason and cost - Review waste weekly with staff - Use surplus-food apps for end-of-day sales - Business waste segregation is legally required - Waste reduction improves GP #### Independent cafés versus chains UK independent cafés compete with large chains such as Costa, Starbucks, Caffè Nero, Pret and Greggs, as well as smaller regional chains. Chains benefit from buying power, brand recognition, marketing budgets, loyalty apps, consistent quality and prime locations. Independents compete through quality, personality, local connection, flexibility and unique experiences. Strategies: focus on speciality coffee and well-trained staff; offer distinctive food, ideally homemade or local; build community through events, local partnerships and friendly service; create a distinctive design and atmosphere; respond quickly to customer feedback; and use social media to tell your story. Price competitively but don’t try to undercut chains on price; compete on value and experience. Know your customers: many people choose independents to support local businesses. Collaborate with other independents rather than seeing them only as competitors; shared events and cross-promotion help. Use data like a chain would: track sales, costs and customer habits. Independent cafés can also adopt chain-like efficiencies, such as standardised recipes, training and good systems, without losing their character. Chains often set customer expectations, such as speed, mobile ordering and plant milk options, so independents should match key expectations while differentiating. - Chains have buying power and brand recognition - Independents compete on quality and personality - Don’t try to undercut chains on price - Collaborate with other independents - Adopt chain-like systems without losing character #### Cash flow for cafés Cash flow, the timing of money coming in and going out, is often more critical than profit for cafés. A profitable café can fail if it runs out of cash. Sales come in daily, often via card payments with settlement delays; costs include weekly or monthly supplier invoices, wages (weekly or monthly), rent (often quarterly in advance), VAT (quarterly), business rates (monthly or as agreed), and irregular costs like equipment repairs. Create a cash flow forecast showing expected income and expenses week by week or month by month, including seasonal variations. Build a cash reserve to cover slow periods and emergencies; many advisers suggest at least a few months of fixed costs. Negotiate payment terms with suppliers, such as 30 days on invoices. Set aside VAT and PAYE money in a separate account so it’s available when due. Monitor card fees and settlement times. Avoid over-ordering stock, which ties up cash. Use accounting software that links to your bank and POS for real-time visibility. If cash gets tight, act early: talk to suppliers, landlords and HMRC (which may agree Time to Pay arrangements) rather than ignoring problems. Good cash flow management reduces stress and supports growth. - A profitable café can still run out of cash - Forecast cash flow week by week - Keep a reserve of a few months’ fixed costs - Set aside VAT and PAYE in a separate account - HMRC may agree Time to Pay arrangements #### Café marketing basics Marketing a café doesn’t need a big budget but does need consistency. Essentials: a Google Business Profile with accurate hours, photos and menu, as many customers find cafés through Google Maps; responding to reviews politely; active social media (Instagram is popular for cafés, with photos of drinks, food, staff and events); a simple website with location, hours, menu and contact details; and good signage outside. Content ideas: new menu items, seasonal specials, behind-the-scenes stories, staff profiles, latte art, coffee origin stories and local partnerships. Events such as cuppings, latte art throwdowns, live music, book clubs and pop-ups draw new customers. Collaborate with local businesses, such as bakeries, gyms and offices, to cross-promote. Loyalty schemes and email newsletters (with consent under data protection and electronic marketing rules) keep regulars engaged. Local press and bloggers may feature unique cafés. Paid advertising on social media can target local audiences cheaply. Track results: which posts drive engagement, which promotions increase sales. Be authentic: customers respond to genuine stories and personality. Consistent quality and service remain the best marketing; word of mouth and repeat customers sustain most successful cafés. - Keep Google Business Profile accurate - Respond to reviews politely - Events attract new customers - Email marketing needs consent - Consistent quality is the best marketing #### Starting a café: costs and planning Opening a café in the UK requires careful planning. Costs include: lease premium or deposit and legal fees; fit-out (design, construction, plumbing, electrics, ventilation, furniture), which can range from modest amounts for a small refurbishment to large sums for a full build; equipment (espresso machine, grinders, fridges, ovens, dishwasher, POS), whether bought, leased or loaned; initial stock; signage and branding; licences and registrations; insurance (public liability, employer’s liability, which is legally required if you have employees, contents and business interruption); staff recruitment and training before opening; marketing for launch; and working capital to cover the first months of operation. Write a business plan with market research, competitor analysis, menu concept, pricing, sales forecasts, cash flow forecasts and break-even analysis. Register your business with HMRC, register as a food business with your local authority, and check planning use class and any licences needed (such as alcohol, late-night refreshment for hot food and drink sold between 11pm and 5am in England and Wales, music, or pavement licences). Get advice from accountants, solicitors and experienced operators. Expect delays and budget contingencies. Many cafés take time to become profitable, so plan funding accordingly. - Budget for working capital, not just fit-out - Employer’s liability insurance is legally required with employees - Register as a food business with your local authority - Late-night refreshment licence covers 11pm–5am - Expect delays and budget contingencies #### Reading café sales data Modern POS systems generate rich data, but it only helps if you use it. Key reports: sales by hour and day (for staffing and opening hours), product mix (which items sell, which don’t), average transaction value, transaction count, sales by category (coffee, tea, food, retail), modifiers (plant milk, extra shots, syrups), discounts and refunds, staff performance, and payment methods. Compare periods (this week versus last week, this month versus the same month last year) to spot trends. Use product mix analysis to decide what to promote and what to remove: high-selling, high-margin items should be prominent; low-selling, low-margin items are candidates for removal. Track the impact of price changes and promotions. Combine sales data with costs for profitability analysis, and with weather and events for context. Set up dashboards or weekly summaries for managers. Share relevant data with staff, such as ATV targets and best-sellers, to engage them. Beware of reading too much into short-term fluctuations. Data protection applies if you collect customer data through loyalty schemes or online ordering. Good data use turns gut feelings into informed decisions and can significantly improve profitability over time. - Analyse sales by hour for staffing - Use product mix to decide what to promote or drop - Compare with the same period last year - Combine sales with cost data - Avoid over-reading short-term fluctuations #### Wholesale coffee for offices and venues Some cafés and roasters supply coffee to offices, restaurants, hotels and other venues, creating additional revenue. Options include supplying beans, providing equipment (bean-to-cup machines or espresso machines) with service contracts, training staff, and offering branded cups or menus. Pricing must cover coffee, delivery, equipment costs, servicing and support time, plus profit. Contracts should specify minimum orders, delivery schedules, equipment ownership and maintenance responsibilities, payment terms and exit terms. Credit control is essential; late-paying wholesale customers can harm cash flow. Quality control matters: a venue serving poor coffee with your name on it damages your reputation, so training and support are crucial. Consider capacity: can your café or roastery supply consistent volumes? Logistics, such as delivery vans, couriers or customer collection, add cost. Wholesale can be particularly valuable for cafés that roast their own coffee, spreading roasting costs over more volume. Start with a few customers and grow carefully. Market your wholesale offer through networking, local business groups and your website. Office coffee demand has changed with hybrid working, so check customers’ actual usage. Get legal advice on contracts and ensure insurance covers wholesale activities. - Wholesale pricing must cover equipment and support - Contracts should cover minimums and exit terms - Credit control protects cash flow - Poor venue coffee harms your brand - Hybrid working has changed office coffee demand
