Rayon d'Or

from Wikipedia, the free encyclopedia

Rayon d'Or is a white wine variety newly bred at the beginning of the 20th century by the French breeder Albert Seibel . It is a cross between Seibel 405 and Seibel 2007 and belongs to the large family of Seibel vines . It is a complex breed in which genes from the wild grapes Vitis rupestris , Vitis aestivalis and Vitis vinifera are present. In 1958, the area under vines in France was 6,965 hectares . In 1999 the area had shrunk to 8 hectares. Smaller vineyards are also known in the United States (→ viticulture in New Jersey , → viticulture in Ohio , → viticulture in Pennsylvania ) and in Canada.

Since it is a hybrid grape, it is not approved for quality wines according to EU regulations.

The variety also served as the basis for the new varieties Seyval Blanc and Vidal Blanc .
