Variety description

10 August 2026

The variety belongs to the mid to mid-late maturity group with a growing season of 160–170 days. The vines are vigorous, and the shoots mature well. Full maturation requires a sum of active temperatures of approximately 3200°C. The variety has low resistance to fungal diseases and pests; frost resistance is moderate, requiring winter cover.

Clusters are cylindrical-conical, winged, and of medium density, weighing from 180 to 500 g; with good care, they can exceed 1 kg. Berries are small, oval, yellowish-green or amber-yellow in color with thin skin and fleshy pulp. It belongs to the I class of seedlessness; seeds are absent or in a rudimentary state.

The grapes are characterized by good transportability and keeping quality. Sugar content at full maturity exceeds 22%. The variety is a climbing vine, so cultivation requires the installation of supports in the form of a trellis or pergola.
