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.
  • Improves fining.
  • Allows the refinement and enhancement of wine structure and length.
