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. Why does milk coffee, once the temperature rises, instead become scalding, less sweet, and coarse in mouthfeel? The core reason lies in protein denaturation and changes in lactose sweetness. Starting from the principles of milk foam formation, this article explains why milk above 70°C leads to difficulty in latte art, separation of foam and coffee, and accelerated foam collapse, and points out that 68°C is already the peak temperature. It also shares the experimental conclusion of Front Street Coffee: 60°C–70°C is the range where lactose sweetness is most pronounced. Finally, it offers practical suggestions, such as using preheated ceramic cups to slow cooling, so that milk coffee maintains its best flavor at a suitable temperature. [more…]
