American coffee is a kind of coffee made with drip-filter coffee pot, which tastes relatively light but slightly bitter. Latte coffee is a combination of Italian espresso and milk, which is relatively sweet, so American coffee is bitter. Latte means milk in Italian. If you order a latte in Italy and there is no coffee in front, the waiter will give you a glass of milk. American coffee is the most common coffee, which is made from black coffee or Italian espresso made by drip-filter coffee pot and a certain proportion of water.
