The negroni was invented in Florence, Italy in 1919, at Caffè Casoni. Count 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 'negroni sbagliato' ("wrong negroni" in Italian) uses sparkling wine (e.g., prosecco) instead of gin.
Negroski is a recipe with vodka again as substitute for gin.
Cardinaloski is a negroski with some angostura drops.
Punt e Mes negroni instead replaces standard red vermouth with a specific, distinctively more bitter-tasting brand called Punt e Mes.
The cin cyn uses Cynar an artichoke based liquor, instead of Campari.
Pinkish negroni is made with pink wine (instead of gin).
A raultini is a variation using Aperol instead of Campari, giving its distinctive orange color, lighter alcohol content, and a bit of sweetness.
The most basic variation is served straight up in a martini glass with a splash of carbonated water floating on top of the alcohol mixture and a twist of lemon zest replacing the orange peel, known as the American version.
Other Italian versions substitute spumante brut or vodka for gin. A sparkling negroni is made with champagne or prosecco.
