FIELD: food industry.

SUBSTANCE: invention relates to winemaking industry. "Quince -D" Saccharomyces cerevisiae yeast strain is deposited in the All-Russian Collection of Industrial Microorganisms (VKPM), Federal State Unitary Enterprise State Research Institute for Genetics, under Registration No Y-3973. Y-3973 strain has spore formation capability, ferments and digests glucose, sucrose, maltose, galactose, 1/3 of raffinose. Saccharomyces cerevisiae VKPM Y-3973 yeast strain has a high fermentative activity, well ferments quince wort containing sugar in an amount of 14.75 g/100 cm³ accumulating 8.79 % vol. of ethanol. The strain can more completely digest carbohydrates with formation of ethanol increased by 0.79 % vol. as compared to a conventionally known strain during the same period of fermentation. The specificity of the wine material produced with usage of Saccharomyces cerevisiae Y-3973 strain in a finer aroma and taste.
