Vitis × labruscana is a subgroup of grapes originating from a hybridization of Vitis labrusca and other species, most commonly Vitis vinifera. Popular examples include Concord and Niagara grapes, which comprise nearly all grapes processed for juice or jelly in the United States. Such cultivars are frequently referred to as "labrusca", however many are as little as half Vitis labrusca in their pedigree. Another common term, arguably more accurate, is "labrusca-type". These varieties do in fact possess many of the traits of Vitis labrusca, frequently including slipskin fruit, strong "foxy" flavor/odor, and large leaves with lighter colored and pubescent undersides. Most are self-fertile, unlike wild Vitis labrusca.
