A Tannin complex added post fermentation to improve structure and protect wine from oxidation. No harshness. While racking or stirring, add to the wine incrementally. Add 3 weeks+ before bottling. Use 0.20-1.14 g/gal (5-30 g/hL) prior to aging.
It is a blend of proanthocyanidic (exotic woods) and ellagic (oak) tannins. It enhances structure, aids color stabilization and provides anti- oxidant protection. It is less reactive and more polymerized than some other tannins, thus it integrates well and provides balance. It is particularly useful in wines with up-front fruit or where smooth tannin structure is lacking.
