This cortado recipe balances a double shot of espresso with an equal measure of steamed milk, keeping the coffee flavor clear while the warm milk smooths.
A cortado balances a double shot of espresso with an equal measure of steamed milk, cutting the intensity without drowning the coffee. The 1:1 ratio keeps the espresso present while the warm milk smooths the edges. You end up with a small, strong drink that takes about five minutes to make and fits in a 4- to 5-ounce glass.
The name comes from the Spanish verb cortar, meaning to cut. The milk cuts the espresso’s acidity and bitterness, but the drink stays coffee-forward. Unlike a latte, which buries espresso under three or four times as much milk, a cortado gives you equal parts of each, so every sip tastes like coffee first.
What Makes a Cortado Different
The 1:1 espresso-to-milk ratio is the defining feature. A double shot of espresso weighs about 36 to 40 grams, and you add the same weight of steamed milk. That keeps the coffee flavor clear while the milk adds body and sweetness.
The milk texture matters as much as the ratio. You steam it to about 60°C (140°F), which is cooler than the milk in a latte. The goal is warm, silky milk with almost no foam, just a thin layer of microfoam on top. Too much air turns it into a cappuccino; too little makes it flat.
A cortado sits between a macchiato and a flat white. A macchiato is mostly espresso with a spoonful of foam on top. A flat white uses more milk than a cortado, usually a 1:2 or 1:3 ratio, and has a thicker layer of microfoam. A latte goes further, with a 1:3 or 1:4 ratio and more volume overall.
Ingredients
- 18 grams coffee beans
- 2 ounces whole milk
Instructions
- Pull a double shot of espresso

How to Steam Milk for a Cortado
Start with cold whole milk in a small pitcher. Submerge the steam wand just below the surface and turn on the steam. You’ll hear a tearing sound as air folds into the milk. Let it stretch for two or three seconds, then lower the wand deeper to stop adding air and focus on heating.
Keep the wand at an angle so the milk spins in the pitcher. This motion breaks up large bubbles and creates a smooth, glossy texture. When the pitcher feels warm to the touch, around 60°C, turn off the steam and wipe the wand clean.
Tap the pitcher on the counter once or twice to pop any remaining bubbles, then swirl the milk gently. Properly steamed cortado milk looks like wet paint: thick, shiny, and barely foamy. If you see stiff peaks or dry foam, you’ve added too much air. If the milk looks thin and watery, you didn’t stretch it enough at the start.
Measuring by Weight Versus Volume
Espresso and steamed milk don’t weigh the same as their volume suggests, which affects the final ratio:
- By volume: 2 ounces of espresso and 2 ounces of steamed milk. Faster, no scale needed, but you’ll get more milk by weight because aeration increases volume without adding mass. The drink tastes slightly milkier.
- By weight: 36 grams of espresso and 36 grams of steamed milk. More precise, keeps the coffee flavor stronger, requires weighing the espresso as it pulls and the milk before steaming.
Most home baristas measure by volume because it’s faster. The difference is small enough that the drink still works. If you want precision, weigh both components.
What to Do When Your Espresso Yield Changes
Espresso machines don’t all pull the same yield from the same dose. Your grinder, your tamp pressure, and your machine’s pump all affect how much liquid ends up in the cup. If your double shot consistently pulls 30 grams instead of 40, you have two choices: adjust the grind to increase the yield, or reduce the milk to match the espresso you’re getting.
Taste the espresso on its own before adding milk. If it’s sour or weak, the yield is too high and you need a finer grind. If it’s bitter or harsh, the yield is too low and you need a coarser grind. Once the espresso tastes balanced, measure how much liquid you pulled and add the same amount of steamed milk.
If you can’t change the grind, maybe you’re using pre-ground coffee or a pressurized portafilter, just match the milk to whatever espresso you get. A 30-gram shot with 30 grams of milk still gives you a cortado. The drink will be smaller, but the ratio stays correct.
Cortado Versus Other Espresso Drinks
| Drink | Espresso-to-Milk Ratio | Milk Texture | Typical Size |
|---|---|---|---|
| Cortado | 1:1 | Warm, silky, almost no foam | 4 to 5 ounces |
| Macchiato | Mostly espresso with a spoonful of foam | Stiff foam on top | 2 to 3 ounces |
| Flat White | 1:2 or 1:3 | Microfoam throughout | 5 to 6 ounces |
| Cappuccino | 1:2 | Thick foam layer | 6 ounces |
| Latte | 1:3 or 1:4 | Steamed milk with thin foam | 8 to 12 ounces |
The cortado’s small size and equal ratio make it the most coffee-forward drink after a straight espresso or macchiato. A flat white has more milk but keeps the coffee present. A cappuccino and latte both bury the espresso under enough milk that the drink tastes creamy first and coffee second.
Common Problems and How to Fix Them
| Problem | Cause | Fix |
|---|---|---|
| Drink tastes too strong or bitter | Espresso over-extracted or milk under-measured | Check your espresso yield and add more milk to match, or coarsen the grind if the shot tastes harsh on its own |
| Drink tastes too milky or weak | Too much milk or espresso under-extracted | Measure the milk by weight to match the espresso, or fine-tune the grind if the shot tastes sour or watery |
| Milk has stiff peaks or dry foam | Too much air added during steaming | Stretch the milk for only two or three seconds at the start, then submerge the wand to heat without adding more air |
| Milk looks thin and watery | Not enough air added during steaming | Keep the steam wand just below the surface for a few seconds longer to fold in more air before heating |
| Espresso and milk don’t mix smoothly | Milk too hot or poured too fast | Steam the milk to 60°C and pour it slowly from a low height so it blends with the espresso instead of sitting on top |
Frequently Asked Questions
What is a cortado?
A cortado is a small espresso drink made with equal parts espresso and steamed milk. The milk cuts the espresso’s intensity without covering up the coffee flavor. It’s served in a 4- to 5-ounce glass and has almost no foam.
What is the correct cortado ratio?
The standard ratio is 1:1 espresso to steamed milk by weight. A typical cortado uses a double shot of espresso (36 to 40 grams) and the same weight of steamed milk. Measuring by volume works too, but the drink will taste slightly milkier because aerated milk takes up more space than its weight suggests.
How much espresso and milk do I use?
Use 18 to 20 grams of ground coffee to pull a double shot of espresso, which yields about 36 to 40 grams of liquid. Add 2 ounces (60 ml) of steamed milk, or match the milk weight to the espresso weight if you’re measuring by scale.
What temperature should I steam the milk to?
Steam the milk to about 60°C (140°F). This is cooler than latte milk, which usually goes to 65 or 70°C. The lower temperature keeps the milk sweet and silky without scalding it or adding too much foam.
How is a cortado different from a latte or flat white?
A cortado uses a 1:1 espresso-to-milk ratio and has almost no foam. A flat white uses a 1:2 or 1:3 ratio with a thicker layer of microfoam. A latte uses a 1:3 or 1:4 ratio and more volume overall, so the coffee flavor is less pronounced.
Should I measure by volume or weight?
Measuring by weight gives you a more accurate 1:1 ratio because espresso is denser than water and steamed milk is lighter than cold milk. Measuring by volume is faster and still produces a balanced drink, though it will taste slightly milkier if you’ve aerated the milk well.
Conclusion
A cortado gives you the full flavor of espresso with just enough milk to smooth it out. The 1:1 ratio and minimal foam keep the drink small, strong, and fast to make. Once you dial in your espresso and learn to steam milk without over-aerating it, you can make a cortado in five minutes that tastes better than most coffee shops serve.
