Variety description

10 August 2026

Bunches are medium-sized, cylindrical-conical, compact, with long, thin peduncles. Berries are medium-sized, oval or elliptical in shape, with thick, astringent skin. Upon ripening, berry color changes from yellowish-green to amber; the surface is densely covered with dots.

The vine has an upright or semi-upright growth habit. The variety prefers deep, warm soils on sun-exposed slopes. Half-long pruning is recommended due to low fertility of buds at the base of the shoots. The variety possesses sufficient winter hardiness and is not very susceptible to coulure.
