Controlled inoculations of non-Saccharomyces yeasts are becoming increasingly used to produce high-quality wines due to their enol. potential. In this study, we evaluated the impact of sequential inoculation with the com. non-Saccharomyces yeasts (Torulaspora delbrueckii and Metschnikowia pulcherrima) in combination with Saccharomyces cerevisiae on the chem. and sensory profile of rosé wines. Sequential inoculation with T. delbrueckii produced wines with an overall reduction in esters, mainly explained by the lower concentrations of Et esters of medium-chain fatty acids and isoamyl acetate. The lower ester concentrations of these wines were related to a reduction in fruity descriptors. An increase was observed, however, in other minor esters such as cinnamates and Et esters of branched acids. Zinc, Et isobutyrate, and Et dihydrocinnamate were selected as potential markers for this fermentation strategy. Sequential inoculation with M. pulcherrima resulted in rosé wines with an enhanced ester profile, reduced acetaldehyde, and increased anthocyans and tannins. Compared to the control wines fermented with S. cerevisiae, the changes observed in these wines were far subtler, especially for the volatile profile, sensory characteristics, and color parameters, with iso-Bu hexanoate and isoamyl butyrate being selected as potential markers.
