EnartisPro FT (Free Thiols) is a blend of PVI/PVP and inactivated yeast rich in immediately available mannoproteins and sulfur-containing amino acids. Because of its high capacity for removing metals, it reduces the activity of oxidases (tyrosinase and laccase) by blocking copper. Consequently, wine is richer in aromatic compounds, presents a fresher color and is more resistant to oxidation and ageing. It is recommended in the vinification of thiolic varieties which protects the varietal aroma and promotes the synthesis of new thiols.
