Despite its name, Americano is an Italian cocktail made with a splash of club soda and equal parts Campari and sweet red vermouth. Campari and vermouth are poured over ice in a glass, and the whole thing is topped with soda water, then garnished with a lemon twist or an orange slice.
It is believed that the first Americano was served at Gaspare Campari’s bar in the 1860s in Milan. Originally, it was named Milano-Torino, referring to the fact that its key ingredients are from Milan (Campari) and Torino (sweet vermouth).
