This webinar aims to provide scientific and practical information for helping winemakers to evaluate if their microbial control strategy in place for the harvest period is correct or can be improved.
PROGRAM
Wine microorganisms: opportunities, threats and control
An overview on classic and new applications of microorganisms in winemaking, the risks related to the uncontrolled development of the main Non-Saccharomyces yeast and bacteria, an introduction to the main strategies for controlling wine microorganisms with SO2, chitosan and Non-Saccharomyces yeast as bioprotective tools.

Microbial Control with Chitosan During Harvest
Microbial control techniques have immeasurably contributed to the global improvement of wine quality. Sulfur dioxide (SO2) has long been the additive of choice for preventing microbial spoilage, but with increasing incidences of microbial resistance to SO2 and consumer demand for low SO2 wines, it is imperative that winemakers explore alternative additives. EnartisStab MICRO (chitosan) is a natural product derived from Aspergillus Niger, which possess antimicrobial and antioxidant properties. This section of the presentation will review the practical application of chitosan in preventing microbial spoilage, referencing real life examples of its application through harvest and vinification.
