What characterizes microfoam produced by a steam wand?

Microfoam produced by a steam wand is characterized by having a creamy and silky texture. This quality comes from the process of steaming milk, where air is added in a controlled manner. The goal is to create very fine, smooth bubbles, which integrate beautifully into the milk, resulting in a velvety texture ideal for latte art and enhancing the overall mouthfeel of espresso-based drinks.

When microfoam is properly created, it does not manifest large, distinct bubbles but rather creates a uniform consistency that blends well with the liquid. This texture also helps in achieving a stable foam that can hold its shape when poured. This contrasts sharply with other types of foam that might be thick, dry, or contain larger bubbles, which are not desirable for quality coffee beverages.
