PROTAN BIO Q
Organic, proanthocyanidin tannin obtained from the quebracho for vinification and refinement purposes
AEB suggests that organic companies consider adding Protan Bio Q quebracho tannin during the fermentation phase which, although extracted from wood, has the same chemical nature as a condensed tannin. This substance binds directly to anthocyanins and tannins in the grapes by means of a polymerisation process and, when included during the mashing process, it removes the polyphenol compounds present in the skin and berries from being acted on by oxygen. Protan Bio Q is obtained via a push extraction process and has ideal characteristics for use in fermentation and refinement. It can be added in combination with Ellagitan ellagic tannins and Boisélevage wood derivatives.
