Crème de cassis is the most renowned liqueur made with blackcurrants and comes from Dijon, the Burgundy region of France. It is rich and sweet liqueur often used to make Kir, a delicious French wine drink. Founded in 1845 and located in Dijon, France, L’Heritier Guyot is one of the oldest producers of crème de cassis and remains the undisputed top estate-produced liqueur brand in France. Drink the liqueur within a year or two after opening the bottle because it tends to spoil.
