What a Cortado Is

The word "cortado" comes from the Spanish cortar, meaning "to cut." A cortado is a double espresso "cut" with an equal amount of warm, lightly steamed milk. That is it. No foam art, no flavoring, no 12-ounce cup.

The milk's job is to reduce the espresso's acidity and bitterness without masking the coffee flavor. You should still taste the bean — the milk is a supporting character, not the lead.

The Ratio

A proper cortado is 1:1 — equal parts espresso and milk. For a double shot (roughly 60ml), add 60ml of warm milk. Total drink size: about 120ml, served in a small glass (traditionally a Gibraltar glass, which is why some cafes call it a "Gibraltar").

The milk should be steamed but not frothed. You want warm, silky milk with micro-bubbles — not the stiff foam of a cappuccino. The texture should be barely thicker than regular warm milk.

Why Cafes Get It Wrong

Three common mistakes:

  • Too much milk. Many cafes serve cortados in 6-8oz cups, effectively making a small latte. If the milk dominates the flavor, it is not a cortado
  • Too much foam. A cortado should have little to no foam on top. Heavy foam changes the drink's character — you are sipping through a layer of air instead of tasting espresso-milk integration
  • Wrong glass. A cortado belongs in a 4-4.5oz glass, not a ceramic mug. The vessel size enforces the correct ratio. If the vessel is too large, the barista is tempted to fill it

Cortado vs Similar Drinks

  • Cortado vs macchiato: A macchiato has just a spoonful of foam on top. A cortado has significantly more milk, fully integrated
  • Cortado vs flat white: A flat white uses more milk (typically 1:3 ratio), has micro-foam, and comes in a larger cup. It is a different drink
  • Cortado vs piccolo latte: A piccolo uses a ristretto (shorter shot) with steamed milk in a small glass. Similar size, different espresso extraction

Making a Cortado at Home

  1. Pull a double espresso (18g in, 36-40g out, 25-30 seconds)
  2. Steam 60-70ml of milk to approximately 55-60C — barely hot to the touch. Do not overheat
  3. Aim for no visible foam. If you see a thick foam layer, tap the pitcher and swirl to reintegrate
  4. Pour slowly into the espresso. No latte art necessary — the drink should be a uniform light brown
  5. Serve immediately in a 4oz glass

The Best Beans for Cortados

Medium roasts with chocolate, caramel, and nutty profiles work best. The milk complements these flavors rather than competing with them. Very light, fruity roasts can taste sour when cut with milk. Very dark roasts can taste ashy.

Brazilian and Colombian beans are natural cortado partners. If you want more complexity, try a Guatemalan lot — the red apple and honey notes integrate beautifully with warm milk.
