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.
