Variety description

10 August 2026

The variety was obtained by crossing the forms Gm 6427-5 and Kanzler. The bushes have weak to medium vigor, and lateral shoot formation is insignificant. The use of vigorous rootstocks, short pruning, and a high-density planting scheme is recommended.

It is an early-ripening variety with good yield, exceeding that of Pinot Noir. The berries are characterized by a sugar content of 22–23% with an acidity of 6–7 g/l.

The plant has high resistance to oidium, low susceptibility to gray mold, and medium to good resistance to mildew. Due to the loose structure of the cluster and the tough skin of the berries, the variety allows for a significant reduction in the number of chemical treatments.
