What is the standard garnish for a Negroni?

The standard garnish for a Negroni is an orange twist. This garnish complements the drink's flavor profile exceptionally well, as the citrus oils from the orange peel enhance the bitter and herbal notes found in the Campari and the gin, while also adding a hint of sweetness from the orange itself. The twist itself adds an aromatic element to the cocktail, elevating the overall drinking experience by providing a burst of fragrance when the glass is brought to the lips.

While garnishes such as a cherry, olive, or mint leaves might be associated with other cocktails—like a Manhattan or a Dirty Martini—the orange twist is specifically recognized as the traditional garnish for a Negroni. This specific pairing is key in maintaining the authenticity and character of the drink.
