Latte Art

There are two main types of latte art - free pouring (pattern created during the pour) and etching (using a tool to create a pattern after the pour). Free pouring is far more common in American cafes, and requires little additional time in preparing a drink.
Free pouring
The two most common forms of poured latte art are a heart shape and the "rosetta" or "rosette", also known as "fern" which resembles a type of flower or fern. Of these, hearts are simpler and more common in macchiatos, while rosettes are more complex and more common in lattes.
