The study aimed to evaluate four Saccharomyces cerevisiae strains, one intraspecific S. cerevisiae hybrid, and five interspecific S. cerevisiae×S. uvarum hybrids with respect to the quality of Moscato di Siracusa DOC wine by comparing them with a commercial Saccharomyces cerevisiae strain. Most of the interspecific hybrids maintained volatile acidity (VA) at very low levels, produced high concentrations of glycerol, malic and succinic acid, and yielded the highest concentration of positive sensory attributes. On the basis of the results of these experimental fermentation trials, a real opportunity to produce special wines employing S. cerevisiae×S. uvarum hybrids is proposed.
