Thought to be a precursor to the Negroni, the Americano was first served in the 1860s at Gaspare Campari’s bar in Milan, Italy. The drink, which features Campari and sweet vermouth in equal parts topped with sparkling water, is an effortless take on the Milano-Torino, which contained Campari and sweet vermouth, sans water. It’s believed that the name stems from its popularity among American tourists. And it’s possible that the name wasn’t affixed until the Prohibition era, when Americans absconded to Europe in droves, thirsty for good drinks.
