Blackcurrant liqueur is a sweet alcoholic beverage made from blackcurrants, small dark berries known for their rich flavor and high vitamin C content. The liqueur is typically produced by macerating the berries in alcohol, often with added sugar, to extract their natural flavors and colors. This liqueur is commonly enjoyed as a digestif or used in cocktails. It can also be drizzled over desserts or mixed into sauces for added depth. Popular brands include Crème de Cassis, which is a well-known blackcurrant liqueur often used in drinks like the Kir cocktail.
