Cocktail folklore has it that this drink, the Negroni Sbagliato, is a mistake or messed up (aka sbagliato) take on the classic cocktail the Negroni. It's said that a bartender at Milan's Bar Bass created the Negroni Sbagliato when he used brut sparkling wine instead of gin.
Make The Negroni Sbagliato: Place ice in a rocks glass or wine glass. Add the sweet vermouth and Campari and stir to combine. Top with sparkling wine, add an orange twist, and serve.
