What drink is created by adding water to espresso?

The drink created by adding water to espresso is an Americano. This beverage is made by diluting a shot (or shots) of espresso with hot water, resulting in a drink that is similar in strength to brewed coffee but maintains the rich flavor profile of espresso. The process of adding water mellows the intensity of the espresso, making it more accessible to those who prefer a less concentrated coffee flavor.

The other options represent different coffee beverages: a macchiato involves adding a small amount of milk or foam to espresso, a ristretto is a shorter, more concentrated shot of espresso with less water used in the extraction process, and an affogato is a dessert that typically consists of a scoop of ice cream or gelato with a shot of hot espresso poured over it. Each of these options has distinct preparation methods and flavor profiles, which distinguish them from the Americano.
