The red grape variety is a new variety between Olmo F2-7(Mazuelo x Cabernet Sauvignon) x Garnacha Tinta. The crossing was made in 1949 by Dr. Harold P. Olmo (1909-2006) at the California Agricultural Experiment Station. The mother variety was created as early as 1936 during the development of the Ruby Cabernet variety. The breeding goal was a special variety for the relatively hot and dry Californian conditions. Incidentally, the new breeding Centurion was created with the same parents. The early to medium ripening vine has sugar-rich berries. It produces red wines of simple character, which are almost exclusively used as blends. In California the variety is mainly grown in Fresno County (219 ha). In 2010, a total of 316 hectares were designated there (Kym Anderson). Further stands are also planned in Australia and Hawaii.
