In this study synthetic musts enriched of EGT were fermented
by different yeast strains to evaluate the influence of both medium
nutrients and yeast strains on the wine final composition. According
to outcomes, no variation in fermentation rate within
strains appeared to be related to nutritional factors. Consequently,
differences in adsorbing phenolics are most likely to be a function
of a different adsorption capacity among yeast strains. The presence
of biotin, pyridoxine, meso-inositol, calcium pantothenate and
thiamine in combination with peptone and tryptone in musts favours
a remarkable reduction of yellow pigments, total tannins, and
