Tannins have a fundamental importance in the fermentation of red wines, both for colour stabilization and antioxidant power. Fermotan Special R represents a step forward in the optimization of the chemical-physical characteristics of wines, improving those aromatic notes required by the market. The gustative result is of great interest, thanks to the softness of the wines obtained with the utilization of this preparation, enhancing the sweet notes of tannins present in grapes.
