The grape variety is a new variety between Emperor x Sultana Moscata. Synonyms are King Rubi, King's Ruby, Moscatel de Malaga and Rubi Sidles. The cross was made in 1939 at the University of California by Dr. Harold P. Olmo (1909-2006). The red-berried, seedless variety is used as table grape. Incidentally, the same parents also gave rise to the new variety Emerald Seedless. No stocks were reported in 2016 (Kym Anderson).

I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
