The variety has above-average vigor vines, often grown on low pergolas. The leaves are small, rounded, nearly entire or weakly lobed, with no pubescence on the underside. Small or medium clusters are cylindrical in shape and of medium density.
The berries are small, ovate, golden-white in color with thin delicate skin and a waxy bloom. The ripening period is early-mid, which allows the variety to adapt to high-altitude conditions. The yield of the variety is low with short pruning.
The variety has low resistance to frosts and fungal diseases, however, in extreme growing conditions, the need for chemical treatment is minimal. It is characterized by unique resistance to phylloxera, which allows the vines to be grown on their own roots.
