Concord grapes are purple or almost dark blue in color. According to the Concord Grape Association, they are grown primarily to be made into grape juice and jelly, though some concord grapes are sold as whole fruit. The dark color of the fruit's skin contains plant-based nutrients called phytonutrients that contain antioxidant properties. Concord grapes and juice are nutritionally rich. They are low in fat and high in vitamins and minerals.
