Hybrid grape produced at U.C. Davis by a cross of Cabernet Sauvignon and Carignan. Though the intent was to produce a grape that had the quality of Cabernet and the heat resistance of Carignan, Ruby Cabernet seems to fair better in cooler climates. Found in the hot San Jaoquin valley where it is used as an ingredient in the "jug" wines of California. Better examples can have aromas of leather and red fruits as well as a decidedly currant-like flavors. Also found in South Africa.
