Chemische Eigenschaften
Cognac is a by-product from the distillation of cognac (brandy). It is present in cognac to the extent of approximately 2%. The aromatic substances present in cognac oil are derived partly from the activities of the particular yeast used and partly from the fermented grapes. It has an intensely strong, almost harsh fruity, oily-fatty, yet green herbaceous odor of outstanding tenacity and great diffuse power. Also see Cognac Green and Cognac White oil.
Chemische Eigenschaften
Cognac green oil is formed during the fermentation of yeast and other sediments in wine lees or from the residual cakes of wine expression in 0.07 to 0.12% and 0.036 and 0.066% yields, respectively. It is the primary constituent responsible for the distinct cognac aroma in wines (i.e., a fruity note).
Cognac white oil is obtained by rectifying raw cognac oil. Cognac white oil exhibits an intense, green, herbaceous odor with a fruity undertone.
Chemische Eigenschaften
Lie de vin oil (green cognac oil or wine lees oil) is obtained by steam distillation of the yeast and other sediments (lees) formed in wine. It is a green to bluish-green liquid with a characteristic cognac aroma.
