Hybridized around 1862 by the Underhill Family of Croton Point, NY. It comes from a seed of Concord fertilized by Black Prince. This is a self-infertile variety, but easily pollinates in a mixed variety vineyard. It buds out late and its leaf pattern looks very much like vinifera, but its thick leathery leaves are olive colored like Concord. Its female flowers open by mid-season and it ripens by mid-season like Concord. The variety is vigorous in the field on heavy loam soils, has good cold resistance, and is only moderately susceptible to fungus diseases. The clusters are large, long, and tapering, moderately compact to moderately loose. The flavors are integrated and full with a combination of soft Native-American labrusca and some Muscat elements.(https://www.hudsonvalleyheritagewines.com/heritage-vines)
