Tannins

Polyphenolic compounds play an important role in the sensory properties of wines. A proper balance contributes to an enhanced aroma profile and structure of wines. Wine tannins can be divided into two categories:

• Condensed tannins or proanthocyanidins: TAN Reactive, SuaviTAN, TAN Sutil, Tanicol SUPER and Tanicol XE offer excellent antioxidant protection and colour stabilization. Also, they increase the structure and body of wines. Their high polymerisation capacity help protect colour stability.

• Hydrolysable tannins or phenolic acids: Galitan, Vinitanon, and Robletan contain gallotannins and ellagitannins specifically tailored to that act as excellent antioxidants and powerful clarifiers while preventing risk of overfining. In an acid environment, as that of wines, they readily hydrolyze releasing phenolic acids, such as gallic acid, digallic or tannic acid and/or ellagic acid, depending on the botanical species the extract is made from. Their antioxidant properties are outstanding and they facilitate clarification in difficult conditions, due to their strong affinity to proteins.
