The Effect of Oak Chip Treatment on Copigmentation of Merlot Wine
Tim Bell, Freemark AbbeyINTRODUCTION Copigmentation in wine is the association, or “stacking,” of anthocyanins (wine pigments) with phenols. Wine color is enhanced by this phenomenon as it renders pigments colored that would otherwise remain colorless. In addition, copigmentation protects pigments from browning reactions, and may hide in the formed stacks the bitter or astringent flavors from the involved copigmentation phenols. …
