From Surfactants to Foam Stability: A Beginner's Guide to Latte Art and the Principles of Fluid Dynamics
Latte art is a romantic expression of a barista's skill, with white milk foam blooming into heart or leaf patterns on the surface of dark brown espresso. Latte art is divided into two types: free-pour latte art and etched latte art created after pouring. The wonder of the former lies in the pattern forming simultaneously with the pour, while the latter offers a wider range of designs because the stable foam allows for leisurely drawing. From a physics perspective, the core of latte art lies in surfactants—molecules that possess both hydrophilic and hydrophobic groups, capable of stabilizing the interface between air and liquid to form lasting foam. Milk proteins and coffee lipids act together as surfactants, enabling the two micron-scale foams to remain clearly separated for a long time after mixing, thereby allowing the pattern to persist.
