Abstract
The aim of this research is to determine the quality of red wines from grape varieties Vranec,
Merlot and Frankovka using wine yeasts from the French manufacturer SELECTYS® LA
DÉLICIEUSE and baker's yeast seeded in a ratio of 0.25 g/L. The research was done during 2020
and 2021 in the Vinica vineyard, where the three grape varieties are grown at an altitude of 400
to 520 m. The determination of the quality of the young wines was done in the State Phytosanitary
Laboratory, where the presence of sugars, alcohol, total acids, volatile acids, the presence of free
and total SO2 were determined with FOSS WINESCAN, while the presence of micro and macro
elements in the wines was determined with ICP/MS. As part of the study, a polyphenolic profile
of the wines obtained was established using the method of Folin Ciocalteau. Statistical analysis of
the data was performed using the Pearson correlation coefficient between the chemical
characteristics of the wines and the yeasts used for the study. The choice of yeasts used for
fermentation is important to obtain high quality wines to satisfy consumer tastes and market
requirements.
Key words: yeasts, wine, fermentation
