The variety has medium growth vigor, bisexual flowers, and medium, deeply lobed five-lobed leaves. Bunches are medium-sized, conical, and often very dense. Berries are medium-sized, round, light green in color, acquiring a yellowish hue in the sun.
The taste of the berries is harmonious and simple, sometimes with a muscat tone; the pulp is juicy and melting. The skin is thin and fragile, which makes the berries prone to cracking and damage by wasps. The variety is sensitive to downy mildew and requires special care.
Used mainly as a table variety, less often for the production of light wines or for decorative purposes. It is rare in industrial viticulture, retaining significance in breeding as source material for developing early varieties.
