The variety is the result of natural crossing and has ancient origins. The vine is characterized by late bud break and late ripening, requiring a significant amount of heat. The variety has high productivity, but is sensitive to downy mildew and powdery mildew.
Bunches and berries are large, dark blue in color with an abundant waxy bloom. The grapes contain a large amount of tannins, acid, and coloring agents. To obtain high-quality wines, it is necessary to limit yields and use less fertile soils.
