The white grape variety is an interspecific cross between wild vines of the species Vitis labrusca x Vitis vinifera. It is an open-pollinated seedling of the variety Diana, which is an open-pollinated seedling of the variety Catawba. The hybrid was selected in 1855 in the US state of New York by the breeder C. W. Grant. The red-berried variety produces white wines with a slightly pronounced Fox tone, which are mainly used for the production of sparkling wine and grape juice. However, it is also used as a table grape. The variety was a crossing partner of the new varieties Moore's Diamond, Excelsior and Reliance (2). However, no stocks were reported in 2016 (Kym Anderson).

For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
