The cluster is large, conical, long, often winged. The berry is seedless, medium-large, ovoid, and elongated-ovoid in shape; the colour is pinkish-red.

Training system and pruning:

vigorous vine with upright growth habit; it prefers expanded training systems such as “tendone”, “pergola” and lyre. Green pruning and sucker removal are required.

Susceptibility to diseases and adverse conditions:

variety with good resistance to downy mildew. Susceptible to phosphorous deficiency.

Overall rating:

very interesting seedless table grape variety for fresh consumption. It has a delicately intense aromatic taste. It has a low detachment rate and therefore it easily falls apart. Administering gibberellic acid, to induce the pedicel thickening, has had positive effects.
