â¢ In coffee drinks, latte means coffee mixed with milk, while macchiato means coffee with a milk âstainâ. â¢ In latte, the addition of milk was used for its flavor and the artwork on top with milk foam is for visual presentation whereas, in macchiato, milk is added for visual presentation. Knowing the difference between these coffee drinks is useful when you stop for coffee at a coffee shop.
For latte, the goal is not to create that much foam, so any type of milk works. For cappuccino, we start with equal portions of espresso and milk. The milk is then frothed (in a special frothing pitcher) into a microfoam that is roughly double the original volume of the milk. The microfoam is then poured over the espresso. (If the espresso is poured into the microfoam, then the drink is called a latte macchiato.)
