A multivariate analysis of variance on Chardonnay wines was carried out with initial sugar contents and yeast strain as the main effects. Results are shown in Table 2. Levels of five out of eight esters, one out of four alcohols, octanoic acid, and ditertbutyl phenol showed significant differences between wines coming from musts with different sugar contents. Only ethyl acetate was higher at lower sugar concentration. When comparing strains, 12 out of 14 compounds were statistically significant among them. The lowest levels for ester compounds and the highest for alcohols were found for the evolved strains L76M2 and/or L76M4.
