POLYGEL W

POLYGEL W is a fining agent made from PolyVinylPolyPyrrolidone (PVPP) blended with silica hydrogel to improve its adsorbing power. The exclusive production process and specific formulation allow the polymer to adsorb polyphenols through hydrogen links with the nitrogen group. This preparation reduces the yellow color of the polymerisable polyphenols in white wines, reduces pinking and aids in preservation of aroma in all wines. POLYGEL W acts with absolute selectivity towards the polyphenolic fraction without interfering with other wine constituents. The treatment reduces astringency and coarseness caused by polyphenols and enhances the wines positive organoleptic characters.
