Oh, I see! When I used to go to school, I also worked part-time at a cafe. When we make americano, it's only espresso and water. If milk is included, that would make it latte or cappuccino depending on the amount of foam. It wouldn't be considered americano anymore. We had to learn different drink types in order to make them. I guess how it works in my country is different elsewhere since we're not supposed to add sugar or milk where I'm from XDXD
