Abstract
The (R)/(S) ratios of acetoin were always higher in wines obtained by Sacch aromyces cerevisiae than in those obtained by Kloeckera apiculata. A signif icantly different behaviour was determined between the two species as regar ds contents and ratios of 2,3-butanediols: S. cerevisiae produced more (R,R )-2,3-butanediol (about 80%), whereas K. apiculata produced more meso-form (about 90%).
