The café Americano is espresso and hot water. Usually two shots of espresso and 12 ounces of water. I think it got its name because it tastes weaker than most European brews
That would make sense! I like that espresso can be turned into a large variety of beverages to enjoy.

I would be drinking espresso all the time if I had that in my home too. Those machines are expensive.
