The Negronicocktail is made of 1 part gin, 1 part vermouth, and 1 part bitter (normally Campari). It is considered an apéritif, or a pre-dinner cocktail intended to stimulate the appetite.
After the success of the cocktail, in 1919 the Negroni Family founded in Treviso, Italy a company named "Negroni Distillerie" (Negroni Distilleries) and created a product ready to use called "Antico Negroni 1919".
According to the most popular origin story, the Negroni was invented in Florence, Italy in 1919, at Caffè Casoni. It was named for Count Camillo Negroni, the man who invented it by asking a bartender (Fosco Scarselli) to add gin to the Americano, his favorite drink. The word Negroni does not appear in English cocktail guides before 1947.
