Ampelographic characters:

apex of green colour with bronzed or pink edges, hairless. Medium, seven-lobed, hairless leaf of bright pale green colour. Closed lyre-shaped petiolar sinus with overlapping edges. Hairless lower side. Medium-sized pyramidal cluster with well separated berries. Medium-small, oval, averagely resistant berry, of purplish red colour with crunchy, sweet pulp and neutral taste.

Training system and pruning:

very vigorous vine; it requires high training systems and long pruning; excellent for warm environments. It needs accurate leaf thinning so that to have a greater illumination and to obtain a better colouration of the clusters, which is sometimes insufficient.

Susceptibility to diseases and adverse conditions:

on the average.

Overall rating:

a good-looking cluster, completely seedless. It finds the best conditions of cultivation in lean soils. With the annular incision, light increases in the weight of the berries and a higher berry-detachment degree are obtained, resulting however in delayed ripening. The clusters should be harvested in different moments so that they can reach a more uniform colour.

Clones undergoing homologation procedure:

Crimson VCR385, VCR390.
