The growing season is approximately 148 days, with ripening dates varying from the second half of August to mid-September. The plant is characterized by very strong growth, high vigor, and dense vines. The variety is prone to parthenocarpy under incomplete pollination.
Bunches are large, conical, moderately dense or loose, with the presence of a wing. Berries are large, weighing about 5.8 g, with crispy flesh and a mauve-pink or red skin, which can be slightly coarse. The flavor is pleasant, sometimes with muscat notes; the berries contain large seeds.
Resistance to fungal diseases is rated as medium. The variety is sensitive to low temperatures and frost, which limits its commercial distribution.
