The variety was obtained as a result of hybridization in 2000, in which the Red Globe variety served as the maternal form and the Flame variety as the paternal form. Propagation of the variety is carried out asexually by grafting onto the Harmony rootstock.
The grapes belong to the early maturity group. The berries are small to medium in size, green in color, have medium skin thickness, and juicy, soft flesh with a neutral taste. The variety is characterized by a high yield potential: up to 20 tons per hectare for fresh consumption and 4–5 tons for raisin production.
In terms of its characteristics, the variety is closest to the Thompson Seedless grape, but differs from it by its earlier maturity.
