Latte art is a decorative technique used in coffee preparation, primarily involving espresso and steamed milk. Baristas create designs by pouring steamed milk into a cup of espresso, allowing the milk's foam to form patterns on the surface. Common designs include hearts, rosettas, and tulips. The skill of creating latte art requires practice and an understanding of milk texture and pouring techniques. The quality of the espresso and the milk's microfoam are crucial for achieving clear and defined patterns. Many coffee enthusiasts enjoy learning this art form to enhance their coffee experience.
