Cold-hardy and robust, Vitis labrusca 'Concord' (Fox Grape) is regarded as the standard of excellence for blue-black American grapes. This vigorous seedless grape variety produces medium-sized clusters of glossy, juicy, blue-black grapes in late mid-season. Highly aromatic, they are excellent for juices, jams, jellies and wine. Its foliage of large, three-lobed, fresh green leaves turns burnished shades of orange and gold in fall.
According to University of California, Davis viticulture expert A. J. Winkler, outside of the vinifera Muscat family of grapes, Vitis labrusca varieties have the most pronounced aromas among wine grape varieties.
