Cappuccino vs Latte vs Flat White: Key Differences

A latte, a cappuccino and a flat white are all espresso plus steamed milk. What separates them is how much milk goes into the cup and how much air was worked into that milk. In their reference definitions, a cappuccino carries a thick layer of foam, a latte is usually the largest and milkiest, and a flat white is a smaller drink than a latte with only a thin layer of glossy microfoam, so the espresso comes through more clearly. As reference sizes, the World Barista Championship definition puts a cappuccino at 150–180 ml in total, a latte is typically 200–300 ml, and a flat white is served in a cup of about 175 ml in New Zealand and often near 200 ml in Australia.

Café menus do not agree on exact sizes, and a chain cappuccino can be more than twice the size of a traditional one. The sections below give the published reference definitions, explain what each one means for a home espresso setup, and show how to steam milk for each drink.

Quick Answer: Which One Should You Order or Make?

• Choose a flat white if you want to taste the espresso and like a silky, even texture with no foam cap.
• Choose a cappuccino if you like a distinct layer of airy foam over a short, strong drink.
• Choose a latte if you want a larger, milder drink where milk leads and the coffee sits in the background.

For a home machine, the flat white and the latte use the same milk technique: a short stretch followed by a long, smooth texturing phase. The cappuccino is the one that needs a deliberately longer stretch to build thick foam.

Understanding the Core Differences

The table collects the reference figures that published definitions give for each drink. Treat them as anchors for comparison, not as a rule every café follows.

Drink	Reference build	Typical serving	Milk texture
Cappuccino	One single shot of espresso, textured milk and foam (World Barista Championship definition)	150–180 ml total	Thick foam, at least 1 cm deep in the competition definition
Latte	One or more shots of espresso with hot steamed milk added	200–300 ml, usually in a glass	Microfoam, with no thick foam layer
Flat white	Double espresso of about 50 ml plus about 130 ml of steamed milk (Anette Moldvaer’s description)	About 175 ml cup in New Zealand; often near 200 ml in Australia	Thin layer of microfoam, about 5 mm in Moldvaer’s description

Another description of the flat white keeps the same 30 ml of extracted coffee used in other drinks on the menu and changes only the vessel: a 175 ml cup instead of the 225 ml vessel a latte is normally served in. The same shot meets less milk in the smaller cup, which is why the flat white tastes stronger even when the espresso is identical.

Cappuccino: The Foam Lover’s Choice

The traditional way to build a cappuccino is in equal thirds: one third espresso, one third steamed milk and one third milk foam. In Italy, a cappuccino is described as 25 ml of espresso with the rest of the cup filled with equal parts milk and foam. The World Barista Championship rules define it as a single shot of espresso with textured milk and foam, at least 1 cm of foam depth, and 150 to 180 ml in total.

Size is the part that varies most. Commercial chains in the United States often serve a cappuccino at 360 ml or larger, which leaves room for far more milk than the reference definition. If a home cappuccino tastes weaker than a café one, compare the cup size before changing the coffee.

Toppings vary by region: variations of the drink add cocoa powder in Europe and Australasia, or cinnamon in the United States and South Korea.

Choose it if you enjoy a short drink with a clear foam layer and a stronger coffee presence than a latte.

Skip it if you find a dry foam cap unpleasant, or your steam wand struggles to build a stable layer of foam.

Latte: The Smooth, Mellow Option

A latte is one or more shots of espresso, usually served in a glass, with hot steamed milk added. The milk is steamed to form microfoam, the very fine bubbles that make it pourable, rather than a separate cap of thick foam. Because there is so much more milk than coffee, a latte is much milkier than a cappuccino and has a milder coffee taste.

That microfoam is also what makes latte art possible. Crema and microfoam are both unstable and start to separate within seconds, so pour as soon as the milk is ready and serve the drink straight away.

Choose it if you want a mild, creamy drink, plan to add a flavoring syrup, or want room to practise pouring patterns.

Skip it if you want to taste the character of a particular coffee. A delicate, fruity espresso is easy to lose in a latte, where milk makes up most of the drink; a flat white or a cappuccino keeps more of it in the cup.

Flat White: The Espresso-Forward Favorite

A flat white generally has a higher proportion of espresso to milk than a latte and does not have the thick foam layer of a cappuccino. The “flat” refers to that thin layer of microfoam. It is often finished with latte art.

Its origin is disputed. Cafés in Australia and New Zealand both claim to have invented it, while the coffee historian Ian Bersten suggests the drink probably began in England in the 1950s, and the name was already in use there in the 1960s.

In Australia a flat white is often served in a ceramic cup of about the same volume as a latte glass, but with less milk and less microfoam. In New Zealand it more commonly comes in a smaller 175 ml cup. Either way, the difference from a latte is the ratio of milk to coffee and the thinner, shinier layer of textured milk on top.

Choose it if you want espresso to stay at the front of the drink with milk smoothing the edges.

Skip it if you find straight espresso too intense, or you want a larger drink to sip slowly. A latte made with the same shot will taste softer.

How to Steam Milk for Each Drink

Steaming has two phases. Aeration, often called stretching, pulls air into the milk; texturing then breaks those bubbles down and spreads them evenly. The three drinks differ mainly in how long you stretch. The sequence below follows Flair Espresso’s milk frothing guide:

1. Purge the wand. Open the valve briefly into a cloth or the drip tray so condensed water does not go into the milk.
2. Fill the pitcher to the bottom of the spout, or about one third of its capacity. Milk expands as it is steamed.
3. Tilt the pitcher about 15 degrees so the milk circulates along the inside wall and forms a whirlpool.
4. Aerate with the tip just at the surface. Flair suggests about three to five seconds for a typical amount, longer for more milk. Correct aeration sounds like a gentle hiss, often compared to paper tearing. A high squeal with no swirling means the tip is too deep.
5. Texture with the tip slightly deeper. Raise the pitcher so the wand stops drawing in air and the whirlpool breaks larger bubbles into smaller ones. Hold the pitcher steady.
6. Stop at about 60°C (140°F). A thermometer is the most precise way to judge it.

How that changes by drink:

• Flat white: keep the stretch short so the surface stays thin and glossy. The finished milk should have no visible large bubbles.
• Latte: use a similarly short stretch, a little longer for the larger amount of milk, then texture until the milk is smooth and pourable.
• Cappuccino: stretch for longer to build volume. Flair’s guide notes that leaving the tip at the surface too long produces a thick cap of stiff, dry foam, which it describes as fine for an old-fashioned cappuccino but not what a latte needs.

If you want an even shorter milk drink, an espresso marked with a spoonful of foam is a macchiato; the macchiato recipe explains how much milk to froth for it.

Espresso Quality

Milk changes how a shot tastes, but it does not repair a poor one. An espresso that runs too fast and tastes sour, or runs too slowly and tastes harsh, will carry those faults into all three drinks. A flat white has a higher proportion of espresso to milk than a latte, so the faults stay easier to taste. Taste the shot on its own before adding milk, and work through an espresso grind adjustment before changing your milk technique.

Temperature

Wikipedia’s cappuccino entry summarizes professional barista standards as steaming milk to about 55–65°C (131–149°F) to keep its sweetness and texture without scalding it. The Flair guide’s 60°C target sits inside that range. A thermometer clipped to the pitcher is a more reliable guide than the feel of the metal.

Choosing a Milk

All three drinks can be made with dairy or plant milk. Plant milks differ by brand and formulation, so one oat or almond milk may foam very differently from another. If a plant milk will not hold its texture, try a version sold for frothing and follow its heating guidance before changing your technique.

Frequently Asked Questions

Which has the most caffeine?

None of the three has more caffeine by definition. Caffeine comes from the espresso, so it depends on how many shots go into the cup. A flat white built on a double shot contains more espresso than a single-shot cappuccino, while a latte may be made with one shot or several.

Is a flat white just a small latte?

Close, but not quite. It is smaller and uses less milk, and its microfoam layer is thinner and shinier than a latte’s. In Australia, where a flat white may be served in a cup about the size of a latte glass, the difference is mainly less milk and less foam.

Why does a café cappuccino taste different from mine?

Size is the usual reason. A 150–180 ml reference cappuccino and a 360 ml chain cappuccino are very different drinks. Match your cup size and number of shots to the café version before adjusting the beans.

Can I make these without an espresso machine?

The definitions above all assume espresso. A capsule machine’s espresso setting can supply that base. Moka pot coffee is strong and concentrated but is not espresso, so a milk drink built on it will differ from the café version; adjust the amount of milk to taste.

Bottom Line

The three drinks share two ingredients. In the reference definitions, a cappuccino is short with a thick foam cap, a latte is usually larger and milkier with microfoam, and a flat white is smaller and stronger than a latte, with a thin glossy layer. If you are learning to steam at home, start with the short stretch used for flat whites and lattes, then lengthen it once you want cappuccino foam.
