- A flat white has a double shot with thin microfoam and very little foam - the strongest coffee flavour of the three.
- A latte uses more steamed milk and has a distinct foam layer on top - it's the mildest and most milk-forward drink.
- A cappuccino is equal parts espresso, steamed milk, and foam - thick, airy, and traditionally served in a smaller cup.
- All three start with espresso. A good bean-to-cup machine like the Philips 5500 Series can make all three at the push of a button.
- Full-fat or barista oat milk gives the best foam for any of these drinks.
Walk into any UK coffee shop and you'll see them on every menu: flat white, latte, cappuccino. Three drinks that all involve espresso and milk, yet each one tastes noticeably different. Order the wrong one and you might end up with a mouthful of foam when you wanted a strong hit of coffee, or a milky drink when you wanted something bold.
The differences between these drinks come down to three things: the ratio of coffee to milk, the texture of the milk, and the size of the cup. Get those right and you'll never order the wrong again.
Here's everything you need to know about flat whites, lattes, and cappuccinos in the UK.
What Is a Flat White?
The flat white is the strongest, most coffee-forward of the three. It originated in Australia and New Zealand in the 1980s and landed in the UK around the early 2000s, where it's now a staple at every speciality coffee shop.
A flat white uses a double shot of espresso (around 40ml) topped with a thin layer of velvety microfoam - steamed milk with very fine, tiny bubbles that give it a silky texture. The key word is "flat" - there's barely any foam on top, just a thin layer of glossy milk. It's served in a smaller cup, usually 160-180ml, so the coffee flavour comes through strong and clean.
What makes a good flat white is the microfoam. The milk needs to be steamed until it's smooth and glossy, with bubbles so small you can barely see them. When poured correctly, the microfoam blends with the espresso rather than sitting on top of it. You get a drink that's creamy but not foamy, with the coffee leading every sip.
In the UK, most speciality shops serve flat whites in ceramic cups around 160-180ml. Chains tend to use slightly bigger cups, which dilutes the coffee strength - something to watch for if you're ordering from a place that doesn't specialise in espresso.
What Is a Latte?
A latte (short for "caffè latte" - Italian for "milk coffee") is the milkiest of the three. It's a single or double shot of espresso topped with a generous amount of steamed milk and a thin layer of foam on top.
A traditional latte is served in a larger cup - 240-300ml - and has a noticeably milder coffee flavour than a flat white. The ratio is roughly 1 part espresso to 3 parts milk, with about 1cm of foam sitting on top. That foam layer is thicker and airier than a flat white's microfoam, but not as thick as a cappuccino's.
Lattes are what most people picture when they think of a coffee shop drink. They're the base for flavoured syrups (vanilla latte, caramel latte, pumpkin spice) and the canvas for latte art. The larger milk volume makes them approachable - if you're not a black coffee drinker, a latte is usually the safest bet.
One thing to note: in the UK, some coffee shops use a single shot in a standard latte and a double in a large. If you want a stronger flavour, ask for an extra shot or order a flat white instead.
What Is a Cappuccino?
A cappuccino is the foamiest of the three. Named after the Capuchin monks (the colour of their robes matched the coffee-and-milk shade), a traditional cappuccino is divided into thirds: one third espresso, one third steamed milk, and one third thick foam.
The foam on a cappuccino is noticeably thicker and airier than both the flat white and the latte. It should be stiff enough that a spoonful holds its shape. The drink is served in a cup around 160-200ml - smaller than a latte, similar to a flat white, but the texture is completely different.
A properly made cappuccino has distinct layers. Take a sip and you'll get foam first, then the warm milk, then the espresso at the bottom. The foam acts as insulation, keeping the drink hotter for longer - which is why cappuccinos are a popular choice for sitting in, especially in colder months.
There's a common belief that cappuccinos are only a breakfast drink in Italy (never after 11am). In the UK, nobody follows that rule - drink one whenever you like. But the thick foam does make them less ideal for takeaways, since the foam collapses in a paper cup.

Making a Flat White
The trick to a great flat white is the microfoam. Steam your milk until it's smooth and glossy - you're looking for bubbles so small they're barely visible. Pour the milk from a low height, tilting the cup as you go so the microfoam flows under the crema.
The result should be a velvety drink with no visible foam on top, just a thin white surface. If you're using a machine without an automatic steam wand, a 4-in-1 automatic milk frother like the SIMPLETASTE makes it much easier to get that silky texture at home.
For a budget option, a handheld frother like the CIRCLE JOY works well for small batches.
Making a Latte
For a latte, steam your milk until it's hot (around 60-65°C) with a layer of light, airy foam on top - about 1cm thick. Pour the milk into your espresso, holding back the foam with a spoon, then spoon the foam on top. A latte is the easiest drink to master at home because the larger milk volume is more forgiving. It's also the best canvas for flavoured syrups - add vanilla or caramel before the espresso for an easy cafe-style drink.
Making a Cappuccino
A cappuccino needs thick, spoonable foam. Steam your milk with the tip of the wand near the surface for longer - you want to introduce more air than you would for a flat white. The foam should be stiff enough that it holds its shape when you spoon it.
Fill the cup one third espresso, one third steamed milk, and spoon the remaining third as foam on top. Dust with cocoa powder or cinnamon for the full cafe experience. Cappuccinos are best enjoyed immediately - the foam collapses after a few minutes.
Which Milk Works Best?
The type of milk you use makes a real difference to all three drinks. Here's how they perform:
- Full-fat cow's milk (whole milk): The gold standard for all three. Around 3.5% fat produces the thickest, creamiest foam and the best mouthfeel. It steams consistently and holds its structure well. If you have one milk in the fridge, this is the one.
- Semi-skimmed (2% fat): The most popular milk in UK households. It foams reasonably well but produces slightly thinner foam that dissipates faster. Fine for lattes, acceptable for cappuccinos, less ideal for flat whites where you want dense microfoam.
- Skimmed (0.1% fat): Produces huge, airy foam that looks impressive but tastes thin and watery. The bubbles are large and the texture is more like soap foam than silky microfoam. Avoid for flat whites.
- Barista oat milk (e.g., Oatly Barista, Califia Farms): The best dairy-free option by a wide margin. These are formulated specifically for coffee - they contain added oils and stabilisers that help them foam almost as well as dairy. Oatly Barista is our top pick for flat whites and lattes. It has a mild sweetness that complements coffee well.
- Almond milk: Splits easily when added to hot espresso and produces thin, unstable foam. It works in a latte where the larger milk volume masks the texture, but don't expect a good flat white or cappuccino.
- Soy milk: Foams reasonably well (especially barista-grade) but can curdle if the espresso is too acidic. It has a distinct flavour that some people love and others hate.
If you're making these drinks regularly, an automatic milk frother is a worthwhile investment. It takes the guesswork out of steaming and produces consistent results with any milk type.
Flat White vs Latte vs Cappuccino - When to Order Each
Your choice depends on what you're after:
Order a flat white when you want a strong coffee hit with a smooth, creamy texture. It's the morning go-to for people who like the intensity of espresso but want something drinkable. If you usually drink black coffee but fancy something with milk, the flat white is your bridge.
Order a latte when you want something comforting and milky. It's the best choice for flavoured coffees (vanilla, caramel, hazelnut) and the most approachable option if you're not used to strong coffee. It's also the best takeaway option - the larger volume and lighter foam hold up better in a to-go cup.
Order a cappuccino when you want texture. The thick foam makes it a tactile experience - you get the heat of the cup, the airy foam, then the warm milk and coffee. Cappuccinos are best enjoyed sitting in, in a ceramic cup, with a spoon and maybe a chocolate dusting. They're the least practical takeaway option but the most satisfying to drink properly.
Frequently Asked Questions
Final Verdict
Flat white, latte, and cappuccino are three distinct drinks that all start with espresso and milk. The flat white is the strongest and most coffee-forward. The latte is the mildest and most versatile. The cappuccino is the foamiest and most textural.
There's no wrong choice - it depends on your mood and what you're after. But knowing the difference means you'll never accidentally order a milky latte when you wanted a punchy flat white, or end up with a mouthful of foam when you wanted a smooth sip.
If you're making these at home, a good bean-to-cup machine with automatic milk frothing is the easiest way to get consistent results. The Philips 3300 LatteGo is a brilliant starting point for under £500. And if you want to experiment with manual frothing, a good automatic milk frother will level up your home coffee game without breaking the bank.
