Kir is a traditional French aperitif that is made from a blend of blackcurrants and either crème de cassis (a sweet, dark red liqueur) or white wine. It can be performed chilled or over ice with sparkling water as an alternative to champagne. As an alternative to Kir, one could enjoy a glass of sangria or its lesser-known cousin, kir royale, which uses champagne instead of white wine. Another option would be to mix together equal parts of cranberry juice and any dry sparkling wine, such as Prosecco, for a simple but flavorful cocktail. For something more creative, try creating a spritzer with your favorite white or red wine combined with a sprig of mint and ginger ale.
