We couldn’t find a clear historical source for this drink, but legend has it that the “Sbagliato” (Italian for “incorrect”) comes from a bartender’s mistaken addition of Champagne into a Negroni instead of gin. What a happy accident! Fancy Champagne isn’t required; any sparkling wine you like will be lovely (we especially like it with Prosecco).
Build in the order given in an ice-filled glass. Garnish with a wheel, slice, or twist of orange.
