The white grape variety (also New York 10-303) is an interspecific new variety between Muscat d'Hamburg x Moore's Diamond. It contains genes from Vitis labrusca and Vitis vinifera. The hybrid was crossed in 1915 by the breeder R. D. Anthony at the Vine Breeding Institute of Cornell University in Geneva- New York. Plant variety protection was granted in 1927. The late-ripening vine is susceptible to botrytis. It produces white wines with a discreet muscat and foxtone. The variety is also used as table grape and as an ornamental vine. It was a crossing partner of the new variety Sovereign Opal. The vine is cultivated in the US states of Illinois, Indiana, Iowa (0.5 ha), Kentucky (0.5 ha), Tennessee and Wisconsin. In Taiwan, the area under cultivation is 50 hectares. In 2016, a total of 50 hectares of vineyard area was reported (Kym Anderson statistics).
