What happens if milk is steamed incorrectly?

Steaming milk is a delicate process that significantly impacts the final texture and flavor of beverages such as lattes and cappuccinos. When milk is not steamed correctly, it can develop a burnt taste due to overheating. This occurs because the proteins in the milk break down and create an undesirable flavor. Additionally, improper steaming can result in a texture that is either too thick or too thin, leading to a lack of the velvety microfoam that is ideal for espresso drinks.

The burnt flavor and unpleasant texture are often the result of not monitoring the temperature closely, leading to scalding. This can turn an otherwise delightful drink into one that is less palatable, detracting from the overall coffee experience. Correctly steamed milk should have a sweet, creamy taste and a silky mouthfeel that complements the coffee, enhancing the drink as a whole. Therefore, understanding how to steam milk properly is crucial for achieving the desired quality in coffee beverages.
