One of the world's most iconic cocktails, the classic Negroni recipe was purportedly invented at Caffè Casoni in Florence, Italy, when Count Camillo Negroni asked for a bolder retelling of the Americano, with gin replacing soda water. With equal parts Campari, gin and sweet vermouth, the ruby-toned cocktail has inspired countless riffs, including the Negroni Sbagliato and the Kingston Negroni, as well as global initiatives like Negroni Week.
