What is used to garnish a Champagne Cocktail?

A Champagne Cocktail is traditionally garnished with a lemon twist. This garnish complements the delicate and effervescent nature of the Champagne, adding a hint of citrus aroma and flavor that enhances the overall drinking experience. The lemon twist is created by cutting a piece of the lemon peel, which retains the essential oils from the fruit, releasing them into the drink when it's added. This not only adds visual appeal but also elevates the taste profile of the cocktail, making it a classic choice for showcasing the Champagne's characteristics.

The other options, while they could be garnishes for various drinks, do not align with the traditional presentation of a Champagne Cocktail. A cherry would more commonly be associated with sweeter cocktails or nostalgic drinks, while a mint sprig fits well with refreshing cocktails, and whipped cream is not typically used in drinks that highlight sparkling wines.
