The main difference between them is the difference in raw materials. The main selling point of latte is the combination of coffee and milk, which is also divided into American latte and Italian latte. Italian latte is pure milk with coffee. American lattes will use milk bubbles instead of some milk to make the taste smoother and richer, and some will have milk bubbles when drinking. American coffee is diluted with hot water, so it tastes bland. People who don't drink coffee are more likely to accept it without the strong taste of espresso. Second, the reasons why American coffee and latte are popular. Friends who love coffee should find that most of the ready-to-drink coffee on the market now is American and latte, so why is it so popular? The main reason is very common and simple. Latte and American have relatively simple requirements for raw materials, mainly espresso and water. Milk does not have very high requirements for milk foam, which can meet the urgent needs of most office workers. In addition, because of their continuous development and improvement, there are more and more varieties, and they have also opened their own popularity. Now the famous caramel macchiato, cappuccino and Nestle coffee are all very popular.
