Latte Art

Technique
Latte art requires first producing espresso with crema and microfoam, and then combining these to make latte art.
Before the milk is added, the espresso shot must have a creamy brown surface, an emulsion known as crema. As the white foam from the milk rises to meet the red/brown surface of the shot, a contrast is created and the design emerges. As the milk is poured, the foam separates from the liquid and rises to the top. If the milk and espresso shot are "just right," and the pitcher is moved during the pour, the foam will rise to create a pattern on the surface. Alternatively, a pattern may be etched with a stick after the milk has been poured, rather than during the pour.
