What characteristics define high-quality steamed milk?

High-quality steamed milk is characterized by a sweet and creamy mouthfeel. This is achieved through the process of steaming milk, which incorporates air and heats the liquid. When done correctly, this results in a velvety texture that contributes to the overall enjoyment of beverages like lattes and cappuccinos. The sweetness in the milk comes from the natural sugars, which become more pronounced when heated, enhancing the flavor of the coffee when combined.

In contrast, other characteristics such as a dry and foamy texture would indicate poorly steamed milk, lacking the necessary creaminess essential for a good drink. Thick and clumpy compositions or a watery consistency also signify improper steaming techniques or insufficient milk quality, which would detract from the sensory experience one expects from a fine espresso-based beverage.
