How to Make a Cappuccino — and What One Actually Is

A cappuccino is espresso with steamed milk and a deep foam layer — the certified Italian definition is 25 ml espresso plus 100 ml of milk steamed to 55°C. The ratio, the steps, and the machines that do it well.

A cappuccino is espresso topped with steamed milk and a substantial layer of milk foam, served small. There is even a certified benchmark: the Italian Espresso National Institute defines its certified cappuccino as 25 ml of espresso with 100 ml of milk steamed to 55°C, roughly 125 ml in a 150–160 ml cup. Home versions vary around that — the constant is a real foam cap over a small, espresso-forward drink.

The ratio: certified vs shorthand

Two descriptions of the same drink circulate. The café shorthand says a cappuccino is thirds — one part espresso, one steamed milk, one foam. The certified Italian definition is more precise: 25 ml of espresso, 100 ml of fresh milk steamed to 55°C, landing around 125 ml in the cup. The shorthand overweights the espresso; the certified version is the better target if you are dialling a machine, and it is the one with a source behind it.

The steps on a home machine

1. Pull the shot first or steam first? On single-boiler machines you cannot do both at once — pull the shot, then steam (the wait between them is a documented limitation of that architecture, not your technique). Dual boilers and bean-to-cup machines do both together.

2. Steam to a fine microfoam. Stretch the milk early with the wand tip near the surface, then submerge to spin and heat. The 55°C certified target is cooler than most people expect — past roughly 65°C milk sweetness degrades, which is why automatic systems stop earlier than instinct would.

3. Pour into the shot, holding foam back briefly so steamed milk enters first, then letting the cap settle on top. In a 150–160 ml cup there is no room to hide a bad shot or thin foam — which is the drink's whole appeal.

Cappuccinos with oat and other plant milks

Plant milks foam differently — barista formulations hold a cap far better than standard cartons. This site publishes a plant-milk suitability rating (1–5) for the machines we review, scored per machine and shown on each review page; the machines below carry theirs on the card, so if oat cappuccinos are the goal you can pick accordingly.

Cappuccino vs latte vs flat white, in one line each

Cappuccino: small cup, deep foam cap, espresso-forward. Latte: larger cup, much more steamed milk, thin foam. Flat white: latte-family drink, smaller and with finer microfoam. The espresso underneath can be identical in all three; cup size and milk treatment define the drink.

Frequently asked questions

What is the cappuccino ratio?

The certified Italian definition is 25 ml espresso to 100 ml steamed milk (about 125 ml total); the common café shorthand is equal thirds of espresso, steamed milk and foam. The certified figure is the better machine-dialling target.

What is the difference between a cappuccino and a latte?

Size and milk. A cappuccino is a small drink with a deep foam layer; a latte is larger, with far more steamed milk and only a thin foam cap. The shot underneath can be the same.

What temperature should cappuccino milk be?

The certified Italian standard steams milk to 55°C — cooler than most home instinct. Overheating past roughly 65°C costs sweetness and texture, which is why automatic milk systems stop early.

Can I make a cappuccino with oat milk?

Yes — barista-formulation oat milks foam well enough for a proper cap. Machines differ in how well their milk systems handle plant milk; our reviews publish a per-machine plant-milk rating for exactly this question.

Can I make a cappuccino without an espresso machine?

You can approximate one with strong brewed coffee and frothed milk, but without pressure-brewed espresso and true steamed microfoam it is closer to a café au lait with foam. The espresso machine is what makes the drink itself.

How do you make cappuccinos at home?

Exactly as the steps above: a shot of espresso, milk steamed with more air than a latte takes, and the thick foam cap spooned or poured to finish. Making cappuccino at home is a steaming skill more than a recipe - the machine list below covers reviewed options with capable steam.
