Cuban Cortadito, Step by Step: The Espumar Technique
Search “cortadito recipe” and most of what comes back is the same shortcut: pull a shot, stir in sugar, add milk, done. That’s not a cortadito — that’s a sweetened, milky espresso. The real technique, the one that gives a proper Cuban coffee its thick, pale-tan foam cap and rounded sweetness, is a step called espumar: whipping sugar with the very first drops of espresso into a thick paste before the rest of the shot ever touches it. It’s a small step that takes about thirty seconds and changes the entire drink. Here’s how to actually do it.
What a Cortadito Actually Is
A cortadito is Cuban espresso (“cafecito”) cut with a small amount of milk — similar in spirit to a Spanish cortado or an Italian macchiato, but built around Cuban coffee’s defining feature: espumita, the whipped sugar-and-coffee foam that goes into every proper Cuban coffee drink, not just the cortadito. The espumar technique is what produces that foam, and it’s done before the milk ever enters the picture. Skip it, and you’ve made a small milky espresso with sugar dissolved into it — drinkable, but not the drink.
What You Need
- Espresso — from a machine or a moka pot; either works for this method, since the technique happens after the shot starts pulling, not during it. If you’re using a moka pot, see our Moka Pot: The $30 Espresso Alternative guide for the brew method itself.
- Sugar — traditionally white granulated sugar, though raw/demerara sugar is also common. About 1–2 teaspoons per serving.
- A small metal cup or pitcher to whip the sugar and first drops in — metal specifically, since you’ll be whipping vigorously against the sides.
- A spoon.
- Milk, warmed or steamed — traditionally evaporated milk in Cuban coffee culture, though whole dairy milk works well too.
The Espumar Technique — Step by Step
This is the whole point of the drink, and the part worth reading twice before you try it.
- Put your sugar (1–2 tsp) into a small metal cup or pitcher before you start pulling the shot.
- As soon as espresso starts dripping from the machine (or the moka pot starts producing its first coffee), immediately catch the first several drops — roughly a teaspoon’s worth — directly into the cup with the sugar. Timing matters here: this needs to be the very first coffee to come through, not a partial or finished shot.
- Whip it vigorously with the spoon, right away, while the rest of the shot continues pulling. You’re not stirring gently — you’re working the sugar and coffee together hard and fast, the same motion as whipping egg whites by hand.
- Keep whipping for roughly 20–30 seconds, until the mixture transforms from dark, wet sugar into a pale tan, thick, almost frosting-like paste — this color and texture change is your signal that it’s actually done, not a fixed clock you’re watching instead of the mixture itself.
- Once the full shot has finished pulling, pour the rest of the espresso into the whipped paste in stages, stirring gently to combine rather than dumping it all in at once — this keeps the foam structure you just built intact instead of collapsing it.
- The result is café Cubano — espresso with the espumita foam already integrated on top. This is the base for a cortadito, but it’s also a complete drink on its own if you stop right here.
Building the Full Cortadito
Once you have your café Cubano (the whipped espresso from above), a cortadito is simply that drink “cut” with a small amount of milk:
- Warm or steam a small amount of milk — roughly 1–2oz, about the same volume as the espresso itself, since a cortadito is meant to still taste strongly of coffee, not become a full milk drink. Evaporated milk is traditional; if you’re using it, warm it gently rather than steaming it the way you would fresh dairy.
- Pour the warmed milk into the café Cubano, or pour the coffee over the milk — either order works, since you’re combining a small volume either way.
- Serve in a small cup, similar in size to a macchiato or cortado. This is a concentrated, sipped drink, not a full mug.
Sugar Choice
White granulated sugar is the most common and traditional choice, and it’s what most Cuban households and cafés use by default. Raw or demerara sugar also works and whips into espumita the same way, with a slightly deeper color and a faint molasses note. Sugar substitutes generally don’t whip the same way — the espumar technique relies on real sugar dissolving and aerating against the hot coffee, and most substitutes behave differently under that process, so this isn’t the place to swap in an alternative sweetener if you want the traditional texture.

Even so, the home version comes in well under a dollar. See How Much You’ll Save Making Coffee at Home for the full annual methodology.
Common Mistakes
- Whipping the sugar with the finished shot instead of the first drops. This is the most common mistake and the reason most home attempts don’t get real espumita — the technique specifically needs the very first coffee to hit the sugar, not the full or leftover shot.
- Stirring gently instead of whipping vigorously. A gentle stir just dissolves the sugar; you need real aeration and agitation to build the foam structure.
- Using a non-metal cup. Whipping vigorously in a flimsy plastic or thin cup is awkward and doesn’t hold up to the motion the way a small metal pitcher does.
- Dumping the rest of the shot in all at once. Pour it in stages, stirring gently, to preserve the foam you just built instead of collapsing it in one motion.
- Adding too much milk. A cortadito is “cut,” not diluted — roughly equal parts espresso and milk, not a milk-forward drink. Too much milk and you’ve made a small latte instead.

FAQ
What is espumar in Cuban coffee?
Espumar is the technique of whipping sugar together with the very first drops of espresso — before the rest of the shot finishes pulling — into a thick, pale, foam-like paste. It’s what creates espumita, the signature foam on top of Cuban coffee, and it’s the step most non-Cuban recipes skip or get wrong.
What’s the difference between a cortadito and a cortado?
They’re closely related — both are espresso “cut” with a small amount of milk in roughly equal proportion. The real difference is technique and origin: a cortadito is built on café Cubano, which includes the whipped espumita sugar foam; a Spanish cortado typically doesn’t include that whipped-sugar step.
Why does my cortadito foam collapse?
Most likely you added the rest of the shot all at once instead of pouring it in stages while stirring gently, or you didn’t whip the initial sugar-and-coffee mixture long enough to build a stable structure in the first place (look for pale, thick, and frosting-like before you stop).
Can I make a cortadito with a moka pot instead of an espresso machine?
Yes — the espumar technique works the same way regardless of how you pulled the espresso. Catch the first coffee to come out of the moka pot the same way you would from a machine, and proceed identically from there.
Do I have to use evaporated milk?
No, though it’s the traditional choice in Cuban coffee culture. Warmed whole dairy milk works well too — the technique and ratio are the same either way.
