* Negroni (cocktail) recipe at International Bartenders Association
The Negroni cocktail is made of one part gin, one part sweet vermouth, and one part bitters, traditionally Campari. It is considered an apéritif, a pre-dinner cocktail intended to stimulate the appetite.
While the drink’s origins are obscured by time, the most widely reported version is that it was invented in Florence, Italy in 1919, at Caffè Casoni, now called Caffè Giacosa. Count Camillo Negroni invented it by asking the bartender, Fosco Scarselli, to strengthen his favorite cocktail, the Americano, by adding gin rather than the normal soda water. The bartender also added an orange garnish rather than the typical lemon garnish of the Americano to signify that it was a different drink. After the success of the cocktail, the Negroni Family founded Negroni Distillerie in Treviso, Italy, and produced a ready-made version of the drink, sold as Antico Negroni 1919. One of the earliest reports of the drink came from Orson Welles in correspondence with the Coshocton Tribune while working in Rome on Cagliostro in 1947, where he described a new drink called the Negroni, “The bitters are excellent for your liver, the gin is bad for you. They balance each other.” 
The standard recipe is very well balanced; however there are some variants. The Negroni sbagliato (“wrong”in Italian) uses sparkling wine (e.g., prosecco) instead of gin. Negroski is a recipe with vodka again as substitute for gin. Punt e Mes Negroni instead replaces standard red vermouth with a specific, distinctively more bitter-tasted brand called Punt e Mes.
