Vitis vinifera
Orion is a white wine grape variety of German origin. It was created by Dr. Gerhardt Alleweldt (1927-2005) at the Geilweilerhof Institute for Grape Breeding in Siebeldingen in 1964, by crossing the "Vitis vinifera" variety Optima with the hybrid grape Villard Blanc. Therefore, Orion is itself a hybrid grape (interspecific crossing) rather than a pure "Vitis vinifera".
