There are two features that distinguish these two espresso-based drinks: the amount of milk and the richness of the milk foam. Depending on the size, a latte is made with a single or double dose of espresso slightly drawn out, to fill about ¼ of the cup. Milk foam is then added to fill the rest of the cup. A cappuccino requires about the same dose of coffee as a latte. The difference is in the milk texture. For a cappuccino, the rest of the cup is filled with hot milk and for the latte, with very thick, dense foam.
