What is the proper temperature range for steaming milk for lattes?

The temperature range of 150-160°F is ideal for steaming milk for lattes because it allows for the perfect balance between achieving a silky microfoam and avoiding scalding the milk. Within this range, the sugars in the milk caramelize slightly, enhancing the flavor and sweetness of the milk, which complements the espresso in a latte beautifully.

Steaming milk beyond this temperature can lead to burning the milk, resulting in a bitter taste and an undesirable texture. It's also important to note that temperatures above 160°F can create a burned flavor in the milk and might make the beverage less enjoyable for customers. Keeping the milk within this specified range ensures that baristas consistently serve high-quality lattes that maintain the optimal taste and texture.
