Blackcurrant absolute (Bourgeons de cassis absolute, cassis absolute) is obtained by solvent extraction via the concrete obtained from the dormant buds of the blackcurrant bush Ribes nigrumL. (Saxifragaceae). The buds are grown and processed, for example, in France (Burgundy). The yield is ～3%. Black-currant absolute is a dark green paste with the characteristic, powerful, penetrating odor of blackcurrants. The typical “catty” note is caused by a sulfurous trace constituent, 4-methoxy-2-methyl-2-butenethiol.
Blackcurrant absolute is used in fine fragrances and in fruity food flavors.

See Currant Black (Leaves). The oil is obtained by steam distillation of the flower buds in approximately 0.75% yields. It is a mobile, pale green liquid with a cymene-like odor.
