What is microfoam primarily used for in coffee beverages?

Microfoam is primarily used in the preparation of espresso-based drinks that involve latte art. This type of foam is characterized by its velvety texture and fine micro bubbles, which allow for better integration with the espresso and a smooth mouthfeel. The microfoam's consistency is essential for creating detailed latte art, as it can be poured and manipulated to form patterns and designs on the beverage's surface.

In contrast, while creating frothy cappuccinos may seem relevant, traditional cappuccinos typically use a thicker layer of froth, which differs from the silky nature of microfoam. Making espresso alone does not utilize microfoam, as it is primarily about extracting the coffee shot rather than frothing milk. Additionally, microfoam does not enhance the flavor of black coffee, as black coffee is served without any milk or foam. Thus, the primary role of microfoam is truly in enhancing espresso-based drinks, particularly for latte art.
