An example of properly steamed milk, considered ideal to pour latte art. Microfoam is milk foamed using a steam wand on an espresso machine, used for making espresso-based coffee drinks, particularly those with latte art. The opposite of microfoam is macrofoam (also called dry foam, in contrast to the wet foam of microfoam), which has visibly large bubbles, a style of milk commonly used for cappuccinos.
Latte art is a mixture of two colloids: the crema, which is an emulsion of coffee oil and brewed coffee; and the microfoam, which is a foam of air in milk. Milk itself is an emulsion of butterfat in water, while coffee is a mixture of coffee solids in water.
