The vines are medium-vigorous. The leaves are medium-sized, rounded, five-lobed, and medium-dissected, with bristly pubescence on the underside. The clusters are small, compact, and cylindrical or cylindrical-conical in shape. The berries are small with a mass of about 1.5 g, blue-black in color with a thick waxy bloom, the skin is medium-thick, the flesh is soft or slightly firm, and the juice is colorless.

The variety is sensitive to major diseases: it shows medium susceptibility to downy mildew and high susceptibility to powdery mildew, gray mold, and wood diseases. The wines possess a deep color and aromas of red and forest berries, spices, and tobacco. The variety requires careful maintenance and proper pruning to maintain high crop quality.
