Fredonia grapes are an extremely winter hardy, Concord-type grape. They are one of the earliest ripening varieties (when compared to the Concord), with vigorous vines. Many people refer to this grape as the money maker, as it is one of the first to fruit. The fruit changes from a beautiful pink to a nearly black color when ripe. Although ripening a bit unevenly on the cluster, the fruit can still be eaten while pink for a more tart flavor. When fully ripe, the grapes are very large, quite blue, and well filled. They have a thick skin, which keeps them resistant to bunch rot and helps protect them from wasps.
