The image has the only illustrative purpose and it is purely indicative; it may not fully reflect the characteristics of the product.

In addition to the products in the FERMOTAN range, during the fermentation phase, AEB offers PROTAN Q SC. It is a Quebracho tannin with low color intensity obtained through a unique process of decolorization of the red hues, typical of this plant species. Although extracted from wood, it has the same chemical properties as a condensed tannin. Characteristically, it will link directly to anthocyanins and grape tannins through a polymerization process and if added during the crushing phase, it will inhibit the activity of oxygen. This quebracho tannin with unique characteristics in this species can be used also on white wines, where it best expresses its action, even at medium high dosages, without compromising the colour.
