What is a coffee’s “crema”?

Trackback |      [pinit]

The “crema” is a unique feature of espresso brewed coffee: a delicate foam that develops on the surface of each espresso shot.

The crema forms because the incredibly high pressure under which water is forced through the ground coffee carries a higher proportion of the beans’ flavorful oils and other compounds into the cup than other brewing methods. These compounds gather together forming bubbles and eventually a stable foam.

The crema gets its name from its delightfully creamy texture.
