Cover Story: Alcoholic fermentation of grapes is a complex microbial process. In the 1980s, Saccharomyces cerevisiae was the first species to be used as a yeast starter, as it grows rapidly and carries out alcoholic fermentation. For the past ten years, Torulaspora delbrueckii has been employed as an alternative yeast starter for winemaking, and several T. delbrueckii strains are now available as dry active yeast. This species must be combined with S. cerevisiae to avoid a stuck fermentation. In this study, we investigate the interaction mechanisms between these two species using a fermentor with a double compartment, allowing for physical separation. We confirmed the existence of cell–cell contact mechanism via a proteomic analysis and the benefits of using T. delbrueckii species under winemaking conditions.
