Café con Leche: Spain’s Coffee With Hot Milk, and How to Make It

Café con leche is strong coffee — usually espresso — mixed with hot milk in roughly equal amounts. To make one, brew a double espresso or a short cup of strong moka pot coffee, heat about the same amount of milk until it is very hot and just below boiling, pour it in and stir, sweetening to taste.

The name simply means coffee with milk, and it is the everyday breakfast coffee of Spain and much of Latin America. It is not a latte with a different accent: it has more coffee, hotter milk and far less foam.

The recipe

1. Brew the coffee into a warmed cup or glass. A moka pot is the usual home method in Spain and Latin America.
2. Heat the milk in a small pan or with a steam wand until it is very hot, with small bubbles at the edge, but not boiling. Stir in sugar now if you take it.
3. Pour the milk into the coffee, aiming for roughly equal amounts, and stir.

Wikipedia's account of the drink describes the café method: make the espresso, use the steam wand to scald the milk to just below boiling, often with sugar added as it heats, then pour the milk over the coffee and stir. Because the milk is heated hot rather than gently stretched, it carries little foam; a café con leche is smooth and uniform rather than capped with microfoam.

Very hot milk tastes slightly different from latte milk. Pushing milk well past 65 °C unfolds more of its whey proteins and brings out the cooked note of scalded milk, which is one reason a latte is steamed more gently. The steaming guide explains the chemistry.

How to order it in Spain

Spanish cafés offer a sliding scale of coffee and milk:

• Café solo — a short black coffee, an espresso.
• Cortado — espresso cut with a little milk.
• Café con leche — roughly equal parts coffee and hot milk.
• Clarito or manchado — lighter, with more milk; oscurito — darker, with less.
• Leche manchada — "stained milk": warm milk with only a little coffee.
• En vaso or de desayuno — served in a glass or as a larger breakfast cup, with more milk.
• Yo lo preparo — "I'll make it": coffee and hot milk served separately, so you mix them yourself.

Some people add a pinch of salt; sugar is the more common addition.

Torrefacto: the coffee behind the flavour

The coffee itself is often distinctive. Much Spanish coffee contains torrefacto beans: coffee roasted with sugar added during the final stage of roasting — typically 10–20%, according to a 2025 review in Foods. The sugar caramelises into a shiny glaze, promotes the browning reactions that create roasted flavours, and is usually mixed with ordinary roasted beans.

The practice is common in Spain, Portugal and several Latin American countries, including Mexico, Costa Rica, Paraguay, Uruguay and Argentina. It began in the 1920s as a cheap way to preserve coffee, and because it was often applied to low-grade robusta, it also served to mask unpleasant flavours.

It changes the cup measurably. In a 2003 study in the Journal of Agricultural and Food Chemistry, espressos made from a blend containing torrefacto-roasted robusta had higher extraction yields and more foam than those made from the same blend roasted naturally — probably, the authors suggested, because caramelised sugar and melanoidins dissolved into the coffee. Dark and intense, torrefacto coffee is a natural partner for hot milk.

Café con leche across the Spanish-speaking world

The drink began in Spain and spread throughout Latin America and its diaspora. In Cuban and Puerto Rican cafés it is often made with sugar already added. In Cuba it is the traditional breakfast, served with buttered, toasted Cuban bread for dipping, and in Miami it is sold through the walk-up ventanitas of Cuban cafés — the Cuban coffee guide covers the rest of that family.

Caffeine and calories

All the caffeine is in the coffee: about 76 mg for a 36 g double espresso at the USDA's average for restaurant espresso, or more in a large breakfast cup with extra coffee. The caffeine guide compares other drinks.

With 100 ml of whole milk at the USDA's 61 kcal per 100 g, plus about 3 kcal from the espresso, a café con leche comes to roughly 65 kcal before sugar. Each teaspoon of sugar adds about 16 kcal.
