Einset (Fredonia x Canner) From Cornell University's Geneva, New York experiment station. This red seedless can be excellent in the right soil, with firm berries and a fruity flavor unlike few other grapes. However, the performance of the vine and the quality of the fruit are quite variable according to the type of soil Einset is grown on. If the soil is too heavy, the vine has low vigor and the fruit is small and lacks flavor. If there is more fertility than the vine likes, clusters may be loose with an odd aftertaste to the fruit.
The vine is hardy to about -15oF. Disease resistance is about the same as varieties such as Himrod and Interlaken. Train it to canes for sufficient production. Ripens three to four weeks before Concord.
