Negroni Sbagliato recipe is more on the bitter side, so be warned, or if you have sweet tooth add some simple sirup in to drink, or even honey would work very well. Sbagliato means mistaken, false or wrong in Italian. Legend has it that the drink was created by mistake when, a few decades ago a bartender at Milan’s Bar Basso making a Negroni grabbed a bottle of prosecco instead of a bottle of gin.
