Survey about the microbiological features, the oenological performance and the influence on the character of wine of active dry yeast employed as starters of wine fermentation. (14th July 2014) - Guzzon, Raffaele
Abstract In this work we compared the microbiological features and the fermentative aptitude of 29 different ADY available on the Italian market. Each sample was essayed by microbiological analysis and fermentations in 3 different grape musts. Attention was focused on the presence of wine spoilage microorganisms inside ADY, and on the degradation/production of secondary metabolites having a relevant impact on the quality of wine.
