The goal of biodiversity preservation is the conservation and enhancement of diversity, which is often stored in different clones of the same grape variety. Fourteen different autochthonous accessions of Aglianico grown in the same area (Vulture, Italy) have been investigated to evaluate the possible significant differences in terms of secondary metabolites belonging to the polyphenolic class, compounds which show a number of beneficial health related properties. During winemaking, grape polyphenols are extracted into wine, therefore the knowledge of the polyphenolic composition of grape is important for the appropriate design of the winemaking process, especially in winemaking management of high-quality red wines. The results of this study are useful tools for the individuation of the most promising candidates in the perspective of Aglianico del Vulture clonal selections from a winemaking point of view.
