Cortado Recipe: Espresso-to-Milk Ratio

A cortado is a small coffee-forward drink made with espresso and warm milk. Roughly equal portions are a useful starting point, though café and regional versions vary. The aim is to soften espresso’s intensity while keeping more of its flavor than a large latte would.

One-drink starting recipe

• One double espresso, approximately 36–40g beverage yield.
• Approximately 40–60ml warm milk for the finished drink.
• A small cup or heat-safe glass, roughly 90–130ml capacity.

Use the basket’s appropriate dose and your normal espresso recipe. The beverage yield is the brewed coffee in the cup, not the dry ground coffee in the basket. Crema makes espresso volume variable, so record beverage mass when you want repeatability. This is a home starting recipe, not a universal definition of the drink.

How to make it

1. Warm your cup and prepare the espresso. Taste it occasionally on its own to check the underlying recipe.
2. Steam fresh cold milk with only a little air at the start, then keep it circulating to integrate the foam.
3. Swirl the pitcher and pour the measured amount of milk into the espresso.
4. Serve immediately. Taste before adding sugar so you can judge the balance.

A steam wand needs enough milk in the pitcher to work properly. If 40ml sits too shallow, use the smallest suitable pitcher and a safe working quantity, then pour only the amount you need. Do not re-steam leftover milk for another drink. Our milk-steaming guide explains how to keep large bubbles out.

Milk texture matters more than latte art

The texture should feel smooth and integrated. A tall cap of dry foam changes the drink’s balance and makes the first sip mostly foam. Too much air usually means the tip stayed near the surface too long. Swirling helps maintain texture while you move the pitcher, but it cannot turn stiff froth into silky milk.

Whole milk is a straightforward option. A barista oat or other plant-based drink is a variation; sweetness, thickness and protein behavior differ by formulation. Try an unsweetened version first if the coffee becomes hard to taste.

Cortado, flat white and macchiato

Drink names are not perfectly standardized. In many cafés a cortado uses less milk than a flat white, while a traditional espresso macchiato uses only a small addition of milk or foam. Order by desired size and coffee-to-milk balance when a menu is unclear.

For a distinctly sweeter small drink, café bombón uses condensed milk. For dessert rather than a milk coffee, affogato pairs espresso with ice cream.

Troubleshooting the taste

If the cortado is harsh, check espresso extraction before increasing the milk. If it tastes too diluted, reduce milk by 10ml and compare. A small change is noticeable in a drink this size. Keep the coffee, espresso yield and milk type constant while making that comparison.
