What is microfoam in coffee preparation?

Microfoam refers to a specific texture of steamed milk that is characterized by its velvety consistency and fine, tiny bubbles. This texture is crucial for creating beautiful latte art, as it allows for smooth pouring and intricate designs. When microfoam is properly made, it creates a rich, creamy mouthfeel that enhances the overall drinking experience, particularly in espresso-based drinks like lattes and cappuccinos.

Achieving microfoam involves a technique called steaming, where the milk is heated and aerated in a way that incorporates air but also breaks down larger bubbles, resulting in a silky texture. This is different from regular foam, which can be denser and less uniform. The quality of microfoam can greatly influence how well latte art can be executed, making it an essential skill for any barista focused on specialty drinks.
