StellarTan™ enological tannins from Polyphenolics are a complete line of grape tannins (condensed tannins) produced from California wine grape varietals that give winemakers the ability to fully optimize the tannin concentration and structure of wine. Located in one of California’s major grape growing regions, Polyphenolics is a leader in development of enological tannins. Fully developed grapes are carefully selected and put through a revolutionary extraction process that’s gentle and preserves the true nature of wine tannins (low temperature / no organic solvents). These tannins solubilize instantly and completely in wine. StellarTan™ enological tannins are available as both finishing and fermentation tannins, each chosen for their total phenolic concentration and varying degrees of polymerization, to give a full complement of options when optimizing tannins in wine.
