To use:
Beer tannin is a high purity tannic acid extracted from gallnut by pure physical method. It is suitable for every stage of beer brewing before fermentation, storage and filtration. It can selectively adsorb the high molecular alkalinity, sulfur group and hydrophobic sensitive protein in beer, reduce the aldehyde substance in beer, and enhance the antioxidant ability of beer. Improve the non-biological stability and flavor stability of beer.
