Tannins consist of a set of monomers named catechins, epicatechins, epigallocatechins and epicatechin-gallate. These monomers occur in different polymeric lengths in the skin and
seed of the grape berry. There is also a difference in the composition of monomers between skin tannins and seed tannins. Only seed tannins contain epicatechingallate.
