The variety was obtained by crossing Princess and Red Globe. The plant has moderate vigor, and shoots have a semi-drooping habit. The maturity group is mid-season, occurring in early August under California conditions.
Conical clusters reach a mass of 680 to 795 g. Berries are medium to large in size, red in color, and oval in shape. The flesh is juicy, the skin is firm, and the flavor has a light muscat hint. Strong berry attachment to the pedicel ensures the variety's suitability for transportation and storage.
