What is a cortado?

A cortado (from Spanish 'cut') is a drink composed of an espresso and an equal — or slightly greater — amount of warm milk, in a ratio of approximately 1:1 to 1:2. The goal is to 'cut' the acidity and bitterness of the espresso with milk without diluting the coffee's intensity. It is usually served in a small glass of 80 to 120 ml.

The cortado originates from Spain — specifically from the Basque and Galician regions — and is very common throughout Spain and Portugal. Its defining character lies in the precise balance between espresso and milk: unlike a cappuccino or latte, the cortado does not aim to create voluminous foam or dilute the espresso, but simply to soften it with a minimal amount of warm, silky milk.

A cortado is typically served in a small straight glass or a short whisky-style glass — the glass allows the distinct layers of coffee and milk to be seen before mixing, adding a visual dimension to the experience. The milk should be heated to 60–65°C and have a slightly silky texture without thick foam. The ideal ratio varies by local tradition: in Spain, the classic cortado is 1:1 (espresso:milk), but in specialty cafés ratios up to 1:1.5 are common.

The cortado is often compared to the Australian piccolo latte (a ristretto in a 90 ml glass with milk) and the French noisette (espresso with a hazelnut-sized drop of milk). These drinks share the same principle — a concentrated espresso softened by a small amount of milk — but differ slightly in ratios, milk texture, and vessel. In North America, the cortado was adopted by specialty cafés from the 2010s onwards and is now common in the best establishments.

In the specialty coffee context, the cortado is particularly valued because it allows appreciation of the aromatic profile of a single-origin espresso while tempering its intensity. An espresso with dark chocolate and hazelnut notes — profiles frequently found in Brazilian or Guatemalan coffees — finds in the cortado an ideal format. A surprising fact: the cortado is one of the few coffee drinks that maintains the same name in virtually every language worldwide, from Barcelona to Tokyo and São Paulo.

The Drink That Refuses to be Oversized

The cortado — from the Spanish word "cortar," to cut — is a study in restraint: a small-format espresso-based drink in which the espresso is "cut" with an equal or near-equal volume of warm milk, typically served in 90-120ml total volume in a small glass. The drink originated in Spain and spread throughout Basque café culture before becoming adopted in specialty coffee globally, where its small size and high espresso-to-milk ratio appeal to drinkers who want the sweetness and textural softening that milk brings to espresso without the dilution that larger milk drinks impose. At a 1:1 to 1:1.5 espresso-to-milk ratio, the cortado preserves more of the espresso's flavour complexity and aromatic character than a flat white or latte while offering more approachability than a straight espresso for those who find pure espresso intensity excessive.

The milk in a cortado is steamed but not frothed extensively — the target is a warm, silky liquid with very fine microfoam integrated throughout rather than a distinct foam layer. This distinguishes the cortado from the macchiato (where a small amount of cold foam is placed on top of espresso without heating) and from a flat white (which uses more milk in a larger total volume and typically has more distinctive latte art foam). The cortado's appeal in specialty coffee lies partly in its precision: there is nowhere to hide a poorly pulled espresso when it is diluted only 1:1 with milk, making the cortado an honest indicator of espresso quality in a way that larger milk drinks — where the milk can mask significant espresso defects — are not.

Practical Recommendations

Order a cortado at a new specialty café to evaluate both their espresso quality and their milk steaming technique in a single small drink. The correctly made cortado should taste primarily of rounded, sweet espresso with a creamy softening from the milk rather than milky with an espresso aftertaste — the balance point is closer to the espresso end of the spectrum. If it tastes bitter, the espresso is either poorly extracted or over-roasted. If it tastes primarily of warm milk, the espresso dose was insufficient or the milk ratio too generous. At home, prepare a cortado with 30g of espresso (double shot) and 40-50g of steamed milk — the glass demitasse or small rocks glass commonly used for cortados in Spanish cafés gives you the visual cue that the total volume should remain under 100ml.
