Caramel macchiato needs stirring, because there is seasoning in it, and the taste will be uneven without stirring. You don't have to stir the cappuccino! There is only coffee and milk in it. However, I always take coffee as an example to say that Italian hot coffee should be drunk early, and the taste of coffee will be much worse when it is cold, especially the dense milk bubbles on it. If it is iced coffee, it needs to be stirred before drinking! !
