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.
