Ruby Cabernet

The red grape variety is a new variety between Carignan Noir (Mazuelo) x Cabernet Sauvignon. Synonyms are Cabernet Ruby, California 234 F2, Roubi Cabernet and Rubi Kaberne. The cross was made in 1936 at the University of California at Davis in California by the breeder Dr. Harold P. Olmo (1909-2006). The breeding objective was to develop a variety suitable for the hot regions in California for Bordeaux-like wines. However, it later turned out to be well suited to much cooler regions. The variety was later used by the same breeder under the breeding number F2-7 for the less successful new varieties Carmine, Carnelian and Centurion.
