Abstract
There are multiple important factors in the wort fermentation process, the final gravity of the wort and the total fermentation time being among them. These factors depend on the fermentation activity of yeasts. The fermentation activity in its turn depends on the concentration of nitrogen and minerals in the wort. The effect of two complex supplements, DistilaVite VM and DistilaVite GN, on the wort fermentation process was analyzed in this study. The first experiment involved comparing the effect of both supplements on carbon dioxide emission and the biomass gain in 100% barley malt wort. Another experiment involved comparing the same strain yeast cultures from the wort morphologically. It has been proved that the use of the DistilaVite VM supplement leads to biomass gain increase of up to 44% and in alcohol yield of up to 2% compared to the control sample. A rather low value of informational entropy H (0.012), compared to the total informative capacity Hmax (0.5), along with the high redundancy factor R (97.8%) shown for the sample with this supplement demonstrate a greater degree of order and a higher level of relative organization for yeast cells of the same strain in the control sample. Therefore, the supplement DistilaVite VM is recommended for obtaining optimal conditions in 100% barley malt whisky washes.
