OENOTANNIN PERFECT - 500 G (OENOT0008)

OENOTANNIN PERFECT is a tannin extracted from grape seeds with a fraction of low molecular weight tannins. Oenological tannins extracted from grape seeds, called condensed or proanthocyanidins tannins are very qualitative tannins. Of the same structure as tannins naturally present in wine, they play a considerable role in its stabilization. OENOFRANCE offers a range of 3 grape seed tannins derived from fresh white grape marc and differing according to their extraction procedures. OENOTANNIN PERFECT is particularly characterized by extra pure proanthocyanidins that are less polymerized than those of OENOTANNIN VELVET or OENOTANNIN INITIAL. OENOLOGICAL PROPERTIES: Removes harshness of wine by initializing polymerization between tannins. Stabilizes color by forming stable pigments with the anthocyanincs in red wines. Protects wine from oxidation. Has high antiradical activity. High proportion of reactive tannic. APPLICATION: For the running off and the end of alcoholic fermentation.
