Bud-burst period: everage.
Ripening period: everage.
Yield: average and constant, sometimes showing green millerandage
Ampelographic characters:
the bud shows an open, whitish-green apex. The pentagonal, five-lobed leaves have a slightly open petiolar sinus with a V-shaped base. The underside is wooly, and the cluster is medium-sized, elongated, pyramid-shaped and averagely sparse. It holds a small berry with an averagely pruinose, thick skin.
Cultural aptitude:
vine of average vigour, with an upright growth habit. It adapts to hilly terrains, even if they are not very fertile.
Training system and pruning:
well suited to Guyot with mixed pruning. Since it has a good basal fertility, the fruiting shoots can be short (5-7 buds).
Susceptibility to diseases and adverse conditions:
normal.
Enological potential:
it gives intense ruby red wines with an excellent aromatic profile with hints of wild berries, plum and morello cherry. It is slightly spicy. Good structure and alcohol content.
