Friends on the first floor said that latte was extremely simple, but it was extremely ignorant. Milk in a latte can't be close to boiling! Generally, milk is heated to 65 to 75 degrees. As for why, please cook a pot of milk yourself and see the effect. There are traditional lattes, brushed lattes or layered lattes. No matter what kind of latte, the drinking method is actually very simple, that is, if there are layers, stir it a little, not too much, otherwise it will reduce the temperature of coffee too quickly and affect the flavor of coffee. If it is a hot latte, you can choose to add sugar according to your own taste, while iced lattes need sugar oil. Fructose or honey is not recommended, because the taste of these sugars will not be compatible with coffee. Don't trust people who really taste coffee without sugar. That's a typical fake B+ petty bourgeoisie. Remember, you're here for coffee, not as a judge of any coffee competition.
