What temperature should milk be steamed to?

Steaming milk is a critical part of preparing various coffee beverages, especially when it comes to creating a velvety texture and enhancing the flavor. The optimal temperature to steam milk is generally around 160 degrees Fahrenheit. At this temperature, the milk reaches its ideal consistency for microfoam, which is important for lattes and cappuccinos. Steaming milk to this temperature ensures that it creates a creamy and rich texture without scorching or burning the milk, which can negatively affect its flavor and texture.

Heating milk beyond this point can lead to some undesirable outcomes. For instance, if the milk is steamed to 180 degrees or higher, it can begin to scald, resulting in an off-putting taste and a less enjoyable mouthfeel. It might lose the sweetness and natural sugars, which are crucial for enhancing the overall flavor profile of the drink. While some bars may have different preferences or practices, the accepted standard for the best result is around 160 degrees.
