The variety belongs to vigorous plants with a mid to late ripening period. The bunches are of medium size, conical or cylindrical-conical in shape, and can be dense or medium-dense. The berries are medium-sized, round, dark violet in color with a bloom and medium-thick skin.
The variety is characterized by low to moderate yield with potential unstable productivity. It possesses low general resistance to fungal diseases, including relative resistance to downy mildew and high susceptibility to grey mold. Short pruning and canopy management are recommended for cultivation.
The grapes are valued for their contribution to blends, providing wines with moderate tannins, good acidity, spicy aromatic nuances, and notes of red berries. The variety's potential for alcohol content and color intensity is low.
