Concord grapes are the best tasting grapes I have ever eaten. Popularized by Welch's products, they taste great as table grapes, grape juice, jam, candy, and even as wine with super health benefits. Sweet and tangy, this marble sized fruit is very nutritious. At maturity, it reaches a height of around 12 feet and will be 5 to 8 feet wide. It does have seeds, but does not need a pollinator. Cold resistant. Zones 5-9.
