The variety is an early table grape with large black berries of elliptical or blunt-ovate shape. The flesh of the berries is characterized by medium density; the taste is neutral.
The bunches of the variety are large, slightly dense. To improve the characteristics of the bunches, the use of gibberellin may be required, which promotes thinning and increasing berry density.
