Concord grapes are native to North America and are grown primarily on the East Coast. Available fresh in September and October, the Concord has a mild, musky flavor and purplish-blue color. It is the grape used to make the jelly in the traditional peanut butter and jelly sandwich.
Concord grapes are rich in antioxidants, which offer health benefits including reduced risk of heart disease, hypertension, cancer, and other degenerative diseases. Concord grapes are also a good source of vitamin C, which may help promote a healthy immune system. To provide additional nutritional benefits, Concord grape juice can be added to processed foods, beverages, desserts, and other food products.
