ABSTRACT:
Liquid natural fermentation products, such as wines, are treated to reduce the content of coloring matter therein without substantially deleteriously affecting the other vinous qualities thereby by the steps of passing the liquid product through a granular bed of a strongly basic macro-porous anion exchange resin in hydroxyl form to substantially increase the alkalinity of such liquid product, then passing the more alkaline liquid product through a granular bed of a strongly acidic cation exchange resin in hydrogen form to generally restore its acidity, and recovering the thus-treated liquid product.
