Espresso

Espresso is a coffee-making method of Italian origin, in which a small amount of nearly boiling water is forced under pressure (expressed) through finely-ground coffee beans. Espresso coffee can be made with a wide variety of coffee beans and roasts. Espresso is generally thicker than coffee brewed by other methods, has a higher concentration of suspended and dissolved solids, and has crema on top (a foam with a creamy consistency).
