Gall tannin with a high reaction power
Gallovin Liquid is a preparation based on purified gall tannins dissolved in a stabilized watery solution, that does not lend any bitter sensation to wines. The gall tannin, thanks to its high reactivity towards protein, reduces the activity of laccase and tyrosinase on anthocyanins and polyphenols, while preserving the must from the combined action of these enzymes with oxygen. For this reason, the utilization of Gallovin Liquid in fermentation safeguards the polyphenolic heritage of wines, preserving them from oxidation.
