Creme de Cassis is a sweet dark liqueur made from blackcurrants. When the chilled sparkling wine hits the creme de cassis in the bottom of each glass, the drink takes on a reddish hue. We especially enjoy a Kir Royale as an aperitif with small bites before dinner. If you would prefer it, a dry white wine can be substituted for the sparkling wine and is just as lovely.
