What characteristic distinguishes microfoam milk?

Microfoam milk is distinguished by its velvety texture, which is achieved through a specific steaming technique that incorporates air bubbles into the milk. This process creates tiny, fine bubbles that result in a smooth and silky mouthfeel, enhancing the drinking experience of espresso-based drinks, such as lattes and cappuccinos. The velvety texture not only complements the coffee but also allows for better latte art, providing a visually appealing presentation.

In contrast, thick and dense milk may indicate the presence of larger, coarser bubbles, which would detract from the smooth texture that defines microfoam. Serving milk cold does not apply, as microfoam is created through steaming, which incorporates heat. Lastly, the creation of large bubbles would lead to a less desirable froth quality, as microfoam is specifically characterized by its small, uniform bubbles that must be carefully crafted during the steaming process.
