IWINE® PRÉVENTION is an innovative vinification aid. It can be used to detoxify the medium (elimination of heavy metals) while decreasing sensitivity to oxidation of the must. This decrease in sensitivity to oxidation is obtained on the one hand by increasing the redox potential through the presence of specific IDY with high reducing power and on the other by the supporting and detoxifying effect (increased CO2 removal) of microcrystalline cellulose. In addition, the autolysis of the IDY present provides increased volume and structure to wines.
