A Negroni is a classic Italian cocktail made with gin, Campari, and sweet vermouth. It is one of the most popular cocktails in the world and is often served as an aperitif.
The Negroni was invented in Florence, Italy, in 1919 by Count Camillo Negroni. Negroni asked a bartender to strengthen his Americano cocktail by adding gin. The bartender obliged and the Negroni was born.
