IOC Gaïa™
(Metschnikowia fructicola)
Natural biocontrol agent for grape harvest during pre-fermentation
Product details
IOC Gaia™ is a natural bio control agent that can be used during red grape harvest and pre-fermentation steps to suppress the growth of microorganisms responsible for acetic acid production, such as Kloeckera apiculate/Hanseniaspora uvarum. It is an active dry yeast (Metschnikowia fructicola) which has negligible fermenting capacity, consequently it will not contribute to alcoholic fermentation. IOC Gaia™’s antimicrobial activity reduces the undesirable population of acetic acid producing yeast, especially Kloeckera, and thus is a natural means to reduce the use of SO2 in picking bins, as well as during pre-macerations and cold soaks of red grapes. Subsequent inoculation with a selected Saccharomyces cerevisiae strain for alcoholic fermentation is not impeded by the use of IOC Gaia™.
