Non-Saccharomyces: Biodiversity under controlWine Yeast Under Investigation #No3 The initial microbial population present in grape must is very diverse. During the early stages of alcoholic fermentation, Saccharomyces cerevisiae is not the dominant specie and other species (non-Saccharomyces) are present. Non-Saccharomyces yeasts are part [โฆ]
