Does Steaming Milk Too Hot Make a Latte Taste Worse? Exploring the Ideal Milk Steaming Temperature and Its Effect on Texture

In the cold of winter, a hot latte or flat white is many people's beloved choice. Many customers ask for "the milk to be steamed hotter," but baristas often insist on the widely accepted steaming range of 55°C–65°C.
