Crème de Cassis is a sweet, dark red liqueur made from blackcurrants. Originating from France, it is often used in cocktails and as a flavoring in desserts. The liqueur has a rich, fruity taste and is typically enjoyed as an aperitif or mixed with white wine to create a popular drink called Kir. The production of Crème de Cassis involves macerating blackcurrants in alcohol, followed by the addition of sugar. The result is a syrupy liqueur with a vibrant color and a strong blackcurrant flavor. It is a key ingredient in many classic cocktails and is celebrated for its versatility.
