Many VCR clones have undergone additional oenological tests, which have been carried out in partnership with the University of Milan and have allowed their oenological characterization by means of the assessment of the subtle parameters. Each clone has been thus described and detailed, not only in its agronomic behavior, but also in its aromatic and, for red-berried clones, polyphenolic profile.
The results of these thorough studies have been collected in the "VCR Technical Booklets " that are now available to growers and winemakers to help them in a more careful choice of the clones according to their oenological goals. Thanks to this research it has been also possible to design those clone / rootstock combinations capable of enhancing even more the agronomical and oenological specificities of each selection.
By now, for many varieties the range of the original "VCR" clones faithfully represents all or almost all the existing intervarietal variability: this allows the optimization of the clonal choice in accordance to each specific oenological target.
