TANIN VR GRAPE® is a preparation of proanthocyanidic tannins extracted from grapes for red wines vinification and ageing.
Due to the high quality of its extraction, TANIN VR GRAPE® contains only a negligible quantity of phenolic acids (Brettanomyces substrates).
Compensates the unbalance on natural grape tannins (lack of phenolic maturity or adverse tannin-anthocyanin ratio).
Stabilises colour due to the formation of tannin-anthocyanin combination.
Allows the refinement and enhancement of wine structure and length.
