Coffee art is a method of preparing coffee created by pouring steamed milk into a shot of espresso and resulting in a pattern or design on the surface of the resulting latte. It can also be created or embellished by simply "drawing" in the top layer of foam. Coffee art is particularly difficult to create consistently, due to the demanding conditions required of both the espresso shot and milk. This, in turn, is limited by the experience of the barista and quality of the espresso machine. The pour itself, then, becomes the last challenge for the coffee artist.
