The variety was obtained by crossing the varieties Emperador and Perlette. The plant is characterized by vigorous growth. Bud burst and flowering occur early. The bunches are large, elongated-conical in shape, often winged, and quite dense. Berries weighing about 4–5 g have a round or slightly flattened shape and a dark red or purple skin color. The variety is seedless, containing seed rudiments.
The flavor of the berries is good; however, full maturity is required to achieve a high sugar level, as the taste may be bland due to low acidity if not fully ripe. The variety is suitable for transport and storage. It is susceptible to fungal diseases and requires standard agrotechnical measures, such as crop thinning and the use of gibberellin to improve bunch characteristics.
