Which beverage is prepared using espresso and hot water?

The beverage that is prepared using espresso and hot water is an Americano. An Americano is made by adding hot water to a shot or shots of espresso, which results in a drink that has a similar strength to traditionally brewed coffee but maintains the rich flavors of espresso. This method creates a smooth and robust beverage, often preferred by those who enjoy the taste of espresso but seek a less intense coffee experience.

In contrast, café au lait is typically made with brewed coffee and steamed milk, giving it a creamier texture rather than using espresso. A red eye involves adding a shot of espresso to brewed coffee, which does not entail the addition of hot water to espresso alone, changing its preparation method. Hot chocolate, on the other hand, is a completely different beverage, made with chocolate or cocoa and milk, lacking any coffee or espresso component.
