Enartis Tan XC is a blend of tannins studied in order to increase colour stability in young red and rosé wines. When added throughout the maceration in fact, TAN XC favours copigment formation between its alcohol extracted monocatechin fraction and the must anthocyanin fraction. The coloured complexes formed in this way are more resistant to oxidation, more soluble in the must/wine and available for condensation reactions with grape tannins.
