The vines are medium-vigorous, with functionally female flowers, which requires the presence of pollinator varieties. The growing season to consumer maturity is about 114 days. Clusters are loose, broadly conical, and of medium to large weight. Berries are medium-sized, round, greenish-white in color, with thin skin and juicy, melting pulp.
The variety is sensitive to downy mildew and gray mold, and is prone to fruit set shedding and 'shot berries', which makes yields unstable. Berries do not transport well due to thin skin and are often damaged by wasps. Wines produced from this grape are characterized by freshness, moderate acidity, and fruity-floral notes.
