Cappuccino, flat white and latte all combine espresso and steamed milk. They differ in drink size, coffee-to-milk ratio and foam texture, though recipes vary between cafés.
All three drinks typically start with a double espresso (around 36g of liquid). The latte often uses a slightly longer pull — towards 1:2.5 or 1:3 — to soften the intensity before the larger volume of milk. The flat white uses a shorter, more concentrated ristretto-style pull in some traditions — particularly the Australian and New Zealand origin — where the espresso is 1:1.5 to 1:2, producing a stronger, sweeter base that cuts through the milk more clearly. The cappuccino uses a standard double espresso. These are the conventional approaches — individual cafes vary — so check the espresso recipe when reproducing a drink at home.
A traditional cappuccino is a 150-180ml drink with roughly equal volumes of espresso, steamed milk and foam — the classic one-third each division. The foam is slightly drier and more substantial than in a flat white or latte: the milk is steamed to incorporate more air, producing a foam that holds its shape on the surface and has some lift above the espresso layer. The result is a drink where you taste the foam and the espresso relatively distinctly — the texture changes as you drink through the layers. In specialty coffee, the distinction has blurred: many cafes serve a cappuccino with wet microfoam similar to a flat white but in a smaller volume than a latte.
A flat white is a 150-180ml drink — similar in size to a cappuccino but with a much thinner layer of foam. The defining characteristic is tight, integrated microfoam: the milk and foam are fully combined into a smooth, silky texture with no visible separation and only a thin (3-5mm) foam layer on top. The result is a drink that is smoother and richer in texture than a cappuccino, with more coffee intensity than a latte of the same size. The espresso-to-milk ratio is higher than in a latte, which gives the flat white a stronger coffee character. It is the drink that most rewards good microfoam technique — without it, a flat white tastes thin and watery.
A latte is a 240-360ml drink — significantly larger than a cappuccino or flat white — with the same double espresso base. The higher milk volume dilutes the espresso intensity considerably, producing a milder, milkier drink. The foam layer is thin (similar to a flat white), with the milk integrated throughout rather than layered. Because the volume is larger, the milk temperature has more time to affect the flavour: milk that is over-steamed (above 68-70 degrees Celsius) tastes scalded and sweet in a way that is more noticeable in a latte than in smaller drinks. A well-made latte has a clean, creamy, gentle coffee flavour where the milk and espresso are in balance.
To make a cappuccino, stretch the milk more aggressively during steaming — introduce more air in the first two to three seconds of steaming to increase the overall volume of the milk by 50-70%. The foam layer should be clearly present when the pitcher is tilted. For a flat white or latte, stretch less: increase volume by 20-30% only, then integrate thoroughly so the foam is fully absorbed into the milk. The finished milk for a flat white and latte should swirl uniformly in the pitcher with no visible thick foam. Using the same pitcher and technique for all three drinks and adjusting only the air-stretching phase is a practical approach for home use.
Cup size and shape affect how the drink looks and feels. Cappuccino is traditionally served in a 150-180ml ceramic cup — wide enough to show the foam surface and thick-walled to retain heat. Flat white is served in a 150-180ml tulip glass or ceramic cup with a narrow mouth that keeps the microfoam intact and visible. Latte is served in a 240-360ml glass or cup — the larger volume works better in a tall, narrow vessel that keeps the milk warmer for longer. Using a latte glass for a cappuccino produces a thin, watery drink even if the recipe is correct: the geometry changes the ratio of foam to liquid in each sip. Matching cup size to drink size is not just aesthetic.
