1 ounce Campari
1 ounce sweet vermouth
1 ounce Prosecco, or more to taste
In Italian, "sbagliato" means "wrong," "messed up," or "mistaken." The twist on the classic cocktail is said to have originated when a rushed bartender making a Negroni accidentally picked up a bottle of Prosecco instead of gin. A fortunate mistake, if you ask anyone who's tried it. A classic Negroni is equal parts gin, Campari, and sweet vermouth, but feel free to add a bit more Prosecco than you would gin, if you like. I've never seen a bartender in Italy measure a Negroni, so you'll be in good company.
