Advances in Wine Yeast Autolysis: Biochemical and Molecular Mechanisms, and the Release of Organic Compounds in White and Sparkling Wines—An Updated Review

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Wine yeasts play a central role in alcoholic fermentation and significantly contribute to the sensory attributes of wines through cellular autolysis during lees aging (sur lie), especially in white wines. This process releases organic compounds that alter the wine's chemical and sensory profile.
