Invented in Florence, Negroni has become popular all over the world. There is a story behind it, involving an aristocrat and a barman.
The place where our scene takes place is called Caffé Casoni, where the Earl Camillo Negroni would always order an Americano cocktail.
One day, the Earl Negroni asked the barman Fosco Scarselli to add some Gin instead of soda, to give an edge to the classic drink. Intrigued by this new version of Americano, other customers started ordering it so much that it became a stand-alone cocktail, named after the Earl Negroni.
Barman Scarselli then added his personal touch: to distinguish Negroni from Americano, he served the first with a slice of orange instead of the lemon slice in the Americano.
As the cocktail became more and more popular, the Negroni family decided to open Negroni Distillerie in Treviso, and started producing Antico Negroni 1919, a ready-made version of the cocktail.
