What is a cappuccino?

A cappuccino is an Italian drink built from one espresso (about 30 ml) and textured steamed milk in near-equal thirds — roughly one-third espresso, one-third hot milk, one-third microfoam — for a 150 to 180 ml total. By Italian custom it is a morning drink, finished before 11 am, and never ordered after a meal.

The word cappuccino traces back to the Capuchin friars, whose brown robes matched the colour of the drink. The modern form appears in Italy after the first steam-driven espresso machines of the 1900s-1910s, but the cappuccino as we know it — with silky microfoam rather than a dry, stiff head of bubbles — is a far more recent invention, popularised in Seattle and Milan through the 1990s alongside the rise of latte art.

The codified Italian standard, defended by the Istituto Nazionale Espresso Italiano, pins the cappuccino at 25 ml espresso plus 100 ml steamed milk, final temperature 55-65 °C, total volume close to 150 ml. Third-wave practice allows a bit more milk (150-180 ml total) and prizes a very fine microfoam — bubbles invisible to the naked eye, a glossy wet-paint texture — that lets baristas pour hearts, rosettas and tulips.

Cappuccino milk tops out at 60-65 °C. Beyond that, proteins denature, the flavour turns sulphurous and the foam collapses. Whole milk (3.5 % fat) gives the silkiest mouthfeel thanks to fat content; semi-skimmed foams more but feels thinner. Plant milks vary wildly: barista-grade oat milk is now the default plant alternative in specialty bars because it textures cleanly, while plain almond remains stubbornly hard to foam.

In Belgium, the Italian 'no cappuccino after 11' rule never stuck — an afternoon cappuccino with a speculoos or a Dinant biscuit is routine from La Hulpe to Bruges. Pours are also often more generous than in Milan, commonly 180 to 220 ml, sometimes billed as 'grand cappuccino' on Flemish menus. Worth knowing: a cappuccino is not a latte macchiato — the macchiato pours the milk first, then the espresso through it, producing visible layers.

Cappuccino vs latte vs flat white

The Balance at the Heart of Italian Espresso Culture

The cappuccino is perhaps the defining drink of modern espresso culture — a beverage that balances three components of equal standing: espresso for intensity and aromatic foundation, hot milk for sweetness and body, and milk foam for texture and temperature insulation. The traditional Italian cappuccino is a 150-180ml drink served in a pre-heated ceramic cup, comprising a double ristretto or single concentrated espresso (around 25ml), steamed whole milk with a thin, dense foam layer integrated throughout rather than piled on top, and no flavour additions. This apparently simple structure conceals considerable technical precision in its preparation: the milk must be steamed to exactly 60-65 °C with a microfoam texture that integrates with the espresso crema rather than sitting on top of it, and the espresso must be pulled at parameters that produce concentrated sweetness and aromatic complexity to withstand the dilution of the milk addition.

The global proliferation of cappuccino has produced significant variation from the Italian standard, with different café cultures developing their own interpretations. In Australia and New Zealand, the flat white evolved as a response to the oversized cappuccino bowls common in those markets — a smaller, more concentrated milk drink with no foam layer that emphasises the espresso flavour more than the milk. In Northern Europe, the cappuccino tends toward larger sizes and more prominent foam. In American specialty cafés, the cappuccino has fragmented into wet (more milk, less foam), dry (more foam, less milk), and bone dry (foam only, no liquid milk) variations that allow personalisation. The Italian original remains the reference point against which all these variations define themselves, though none is inherently less valid.

Practical Recommendations

A well-made cappuccino is one of the most challenging drinks to prepare consistently across every service, which is why it serves as a quality indicator in specialty café evaluation. Request a cappuccino at a new café and examine three things: the cup temperature (should be warm to the touch but not too hot to hold), the texture (should feel velvety and integrated rather than frothy or thin), and the first sip impression (should taste of sweet, caramel-rounded espresso with creamy texture, not bitter or milky). A cappuccino that tastes primarily of bitter espresso is under-extracted or under-dosed; one that tastes primarily of warm milk has insufficient espresso concentration. If you make cappuccinos at home, invest in milk thermometer to consistently hit 60-65 °C — this temperature range is where milk sweetness peaks and where foam texture is most stable and pleasant.
