The variety is a hybrid of Princess and Red Globe. The vines are characterized by vigorous growth and high fertility, for which reason short pruning to 2–4 buds is recommended. At low temperatures, uneven bud break is possible due to apical dominance.
The berries are large, 20–26 mm or more in diameter. Sugar content is 17–19° Brix; the taste is neutral and sweet. The skin is thin, the pulp is firm and juicy. The variety has good transportability and retains quality after 6 weeks of storage.
