The Concord grape got its start from a wild grape that was native to New England. As one of the few grapes derived from North America rather than Europe, they are well recognized in the US. If you've had Welch's grape juice you'll recognize the strong color and taste from Concord grapes. Concords have a deep, sweet flavor, that finishes off with a tartness that keeps them from being overwhelmingly sweet. They have a slip-skin, and the pulp is easily separated from the peel.
