AB  - The stability of free and glycosidically-bound fractions of some components of Muscat grape aroma (terpenols and aromatic alcohols) was investigated during alcoholic fermentation and in wines of different ages. Some free terpenols, such as linalool, vary little during fermentation; for others, such as geraniol, the decrease is considerable. Hydrolysis of bound terpenols is low. During wine aging, and depending on the different terpenols, slow hydrolysis of terpenoid glycosides seems to occur in wine. Free linalool and α-terpineol increased while geraniol and nerol decreased in older wines.
