Tannin: what is it?

Tannin is a natural substance present throughout the plant kingdom: in wood, bark, rhizomes, roots and fruits. It is part of the polyphenols family, a term that you may have already heard.



Polyphenols are antioxidant substances found in fruits, vegetables and, in general, in different plants, which help to preserve tissues against cellular ageing.


As a result, tannin is 100% natural.


The “family” includes different molecules, so that it would be more correct to ask “what are tannins?” The difference lies in their chemical structure and their different botanical origins.


But all tannins have common characteristics that have allowed them to become silent companions of the whole path of human civilization, from the ancient times until our days.
