the bud presents a slightly tomentose, green-whitish apex with carminate edge, moderately folded apical leaflets, pale green with slight tomentum. The leaf is medium-large, pentagonal, with three or five lobes, and with a dark-green, opaque, slightly bullous, thick flap. The petiolar sinus is slightly opened or closed, with a U-V-shaped petiolar sinus. It has a medium-large, cylindrical-conical, winged, rightly sparse cluster. The berry is of medium-large size, spherically shaped and has a uniform dark blue color. The skin is pruinose and quite thick; the pulp is medium crunchy with a sweet, simple, pleasant taste.

adaptable to different training systems, provided they are expanded; preferring the “tendone”, the “pergola”, and the espalier also with spurred cordon.

susceptible to powdery mildew and dead arm and normally to other diseases and parasites. Shows incompatibility phenomena if grafted on Kober 5BB.

highly resistant to transport and quite suitable for conservation. Fairly accepted on both domestic and foreign markets for its uniform color, crunchy pulp, and small cluster. The presence of a high number of grape seeds does not allow a high level of consumer satisfaction.
