Description

The purpose of the present work was to study the evolution of condensed tannins according to their degree of polymerization in seeds, pulp and skins, along the maturation using Cabernet Sauvignon and Tinta Roriz (Vitis vinifera L.) varieties. Additionally for this study a witness of each variety was compared with two modalities of fruit pruning, one of 50% and another one of 75%.
