The Negroni is a classic Italian cocktail made with equal parts gin, Campari, and sweet vermouth. It's stirred with ice, strained into a glass over ice, and garnished with an orange peel. Known for its bitter-sweet taste, the Negroni is a popular aperitif. It originated in early 20th century Florence when Count Camillo Negroni asked for a stronger version of the Americano cocktail, replacing soda water with gin.
