The Milan-invented 'wrong negroni': Campari, sweet vermouth and Prosecco (in place of gin) over ice with an orange slice. Lighter, brighter, lower-alcohol than the classic, born by accident at Bar Basso in 1972.

The Negroni Sbagliato was invented at Bar Basso in Milan in 1972 by bartender Mirko Stocchetto, who reached for the wrong bottle and grabbed Prosecco instead of gin. The mistake became a Milan institution. Bar Basso still serves it from the original counter; Camparino in Galleria's Vittorio Emanuele II location, opened in 1915, pours the canonical city Campari aperitivo.
