The white grape variety is an interspecific new variety between Seyval Blanc x Schuyler. Synonyms are Geneva White 7, GW 7 and NY 33-472. It contains genes from Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1945 at the Grapevine Breeding Institute of Cornell University in Geneva, New York State, and released in 1996. It is grown in the northern USA and Canada. The variety yields white wines with a light foxy, but is mainly used for grape juice production. No stocks were reported in 2016 (Kym Anderson statistics).
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".Prof. Dr. Walter Kutscher
