The Negroni is a classic Italian cocktail made of one part gin, one part vermouth rosso, and one part Campari, garnished with an orange peel. It is widely believed to have been invented at Caffè Casoni in Florence in 1919. Legend has it that Count Camillo Negroni asked his bartender, Forsco Scarselli, to strengthen his favorite cocktail, the Americano, by replacing the soda water with gin. The bartender also swapped the usual lemon garnish for an orange peel to signify that it was a different drink. This simple substitution created a robust, bitter, and complex beverage that has become a staple of the 'aperitivo' culture. Today, the Negroni is celebrated globally during 'Negroni Week,' and it is often cited by bartenders as the perfect example of a balanced three-ingredient cocktail.
