Seyval blanc is a hybrid wine grape variety used to make white wines. Its vines ripen early, are productive and are suited to fairly cool climates. Seyval blanc is grown mainly in England, the United States East Coast, in the Pacific Northwest (Oregon), as well as to a lesser extent in Canada. Seyval blanc was created either by Bertille Seyve, or his son-in-law Villard, as a cross of Seibel 5656 and Rayon d'Or, and was used to create the hybrid grape St. Pepin. Seyve and Villard used the same Rayon d'Or x Seibel 5656 crossing to produce the red wine grape Seyval noir.
