This popular Italian cocktail comprises one part gin, one part vermouth rosso (red, semi-sweet), and one part Campari. It is garnished with a slice of orange peel and is usually taken as an aperitivo.
Although the origins of the drink are not certain, the story goes that it was invented by Count Camillo Negroni in 1919 when he asked a barman to strengthen his usual tipple, the Americano, with gin instead of the traditional soda water. The barman obliged, adding an orange garnish, and thus the Negroni was born.
The drink gained greater prominence after Orson Welles enjoyed it while filming in Rome in 1947. The American cinema legend allegedly said: "The bitters are excellent for your liver, the gin is bad for you. They balance each other."
