An Americano coffee is a type of coffee drink made by diluting an espresso shot with hot water at a 1:3 to 1:4 ratio, resulting in a drink that retains the complex flavors of espresso, but in a lighter way. The strength of the drink varies with the number of shots of espresso and the amount of water added. The name "Americano" means "American" in Italian, Spanish, and Portuguese. The drink is believed to have originated during World War II when American soldiers stationed in Italy diluted espresso with hot water to approximate the coffee to which they were accustomed. An Americano is not the same as regular brewed coffee, as it is made from coffee that has already been brewed. The drink is served without milk, but some people may choose to add a splash of their favorite dairy or non-dairy product for an extra bit of flavor. An Americano provides a distinctively powerful taste without being too strong or bitter, and it has the boldness of traditional coffee but without too much bitterness because the hot water tones down its taste. The caffeine content of an Americano coffee can vary depending on the number of espresso shots it contains.
