The effect of increased amount of yeasts on fermentation results of winemaking sets with high content of sugars was studied. Sets with the total sugars content 340,9-399,0 g/dm3 and yeasts of the Bratislava race from the S. bayanus species, of the Malaga No. 36 and Malaga No. Im/35 races from the S. сеrevisiae species were applied. The fermentation was performed at the temperature of 20°C at application of different yeast doses: 5%x 10% of mother yeast, 5% of mother yeast + 1-2-day shaking and yeast slurry in the amount of 1.1-2,0%. The best fermentation was found in the casé of inoculation with mother yeast in the amount of 10%r somewhat worse in the case of slurry. The Bratislava race yeasts fermented usually somewhat better that the remaining ones.
