Seyval Blanc (or Seyve-Villard hybrid number 5276[1]) is a hybrid wine grape variety used to make white wines. Its vines ripen early, are productive and are suited to fairly cool climates.[1]Seyval Blanc is grown mainly in England,[2][3] and the Finger Lakes region of upstate New York,[2] as well as to a lesser extent in Canada.[1] Seyval Blanc was created either by Bertille Seyve, or his son-in-law Villard, as a cross of Seibel 5656 and Rayon d'Or (Seibel 4986),[4] and was used to create the hybrid grape St. Pepin.
Seyval Blanc has a characteristic citrus element in the aroma and taste, as well as a minerality that may be compared to white Burgundy.[2] It is often oaked and subjected to a stage of malolactic fermentation.[2]
As it contains some non-vinifera genes, it is outlawed by the EU authorities for quality wine production, which is an issue of conflict with the English wine industry.[1]
Seyval Blanc is known under the synonyms Seival, Seyval, Seyve Villard 5-276, Seyve Villard 5276, and SV 5276.[4]
