One performs obtainment of a fermentative mixture, introduction of yeast autolysate in an amount of 1.8-3.0% of the mixture weight into the fermentative mixture, repeated fermentation of the mixture and wine enrichment with yeast biologically active substances. Autolysate is prepared from such yeast biomass by way of thermal treatment at temperature of 55-60°C during 15-20 hours, self-cooling to 37-42°C with subsequent fermentative treatment with fermentative preparations of ?-glucosidase and ?-galactonurase activity or their mixture at a ratio of 1:1.
