Q » Why does milk foam when heated for coffee?
30 Oct, 2025
A » Milk foams when heated due to the presence of proteins and fats. When milk is steamed, proteins like casein and whey unfold, trapping air and forming bubbles. The fats stabilize these bubbles, creating the rich foam that enhances coffee. Proper steaming techniques, including the right temperature and aeration, are essential for achieving the desired texture and consistency in milk foam for coffee beverages.
