Chardonel
(Plant patent 7860) was named by Cornell University in 1990 due to superior performance in Michigan and Arkansas. Cold hardiness has been nearly as good as for Seyval in New York, but good locations with long growing seasons are required to fully ripen the fruit. This cross of Seyval x Chardonnay produces an excellent wine when fully ripened, with fruit aromas characteristic of Chardonnay and Seyval. The potential for sparkling wine production appears to be good.
