The influence of yeasts type and malolactic fermentation on the quality of Teran wines

The aim of this study was to determine the effect of different yeast species with regard to degradation of malic acid (BDX Uvaferm and Lalvin 71B) individually and in combination with spontaneous and induced (Uvaferm Beta) malolactic fermentation in wine quality Teran. In terms of alcoholic fermentation, there were no significant differences with respect to the applied yeast, as in the basic physico-chemical analytical wines. The share of malic acid in wine after alcoholic fermentation using yeast Lalvin 71B is reduced by 25% due to its malo ethanol activities. Wines in terms of aromatic components are not significantly different, whereas gustatory harmonious wine shows for which he used the yeast Lalvin 71B. Spontaneous malolactic fermentation took longer (10-30 days longer) than induced, there was no significant increase in volatile acidity. In all treatments, malic acid degradation was complete (0.00 g / L). The greatest differences were observed in terms of aromatic sensations of wine. Samples of wines in which malolactic fermentation carried out by the addition of lactic bacteria cultures Uvaferm Beta showed significantly better results in terms of typicality, intensity and durability of the odors.
