The variety is a complex interspecific hybrid. The vines are characterized by vigorous growth and high yield, which requires regulation. The clusters are cylindrical-conical, of moderate density, weighing 500–800 g, with some reaching 2 kg. The large berries have an ovoid shape and white color; the flesh is fleshy-juicy with a simple, harmonious taste and a possible light muscat aroma.
The plant has moderate disease resistance: it is susceptible to downy mildew, powdery mildew, grey mold, anthracnose, and phylloxera, therefore requiring fungicidal protection. Frost resistance is -21...-22°C; winter covering is required. The variety is prone to berry cracking when soil moisture changes, and poor vine maturation is observed with an excess of nitrogen fertilizers.
