A drink made with champagne or sparkling wine, either as the base ingredient (as in a Champagne Cocktail or a Buck’s Fizz), or splashed atop another drink, typically a sour such as in an Old Cuban, an Air Mail or a French 75, but also applicable to some Spirit-Forward Cocktails as with a Seelbach or an Ancestral-style such as a Morning Glory Royale. For fun, try tapping a half-ounce or so of brut Champagne into a Manhattan sometime—really, it’s delicious, dangerously so.
