Vine vigorous, usually hardy, productive, somewhat susceptible to mildew. Canes long to very long, numerous, usually thick, dark brown to slightly reddish-brown covered with a small amount of blue bloom; nodes not enlarged, very slightly flattened; internodes intermediate in length; diaphragm of average thickness; pith medium to above in size; shoots nearly glabrous; tendrils intermittent, fair length, bifid to trifid. Leaf-buds open early, of average size, short, of medium thickness, obtuse to conical. Young leaves heavily tinged with carmine on lower surface, faintly tinged along margin of upper surface, prevailing color bright carmine. Leaves large to medium, of average thickness; upper surface light green, slightly glossy, nearly smooth; lower surface pale green, somewhat pubescent; veins rather indistinct; lobes vary from none to three, terminus acute; petiolar sinus deep, narrow, sometimes closed and overlapping; basal sinus usually lacking; lateral sinus shallow and narrow; teeth shallow to medium, of average width. Flowers open in mid-season, sterile; stamens reflexed. Fruit ripens with Concord or later, keeps very late. Clusters variable in size, medium to short, very broad, slightly tapering to nearly cylindrical, upper part of cluster often subdivides into several parts making compound clusters, frequently double-shouldered, usually compact; peduncle short, medium to rather stout; pedicel above average length, moderately thick, covered with few small warts, enlarged at point of attachment with fruit. Berries large, oval to spherical, dark purplish-black to black, glossy, covered with heavy blue bloom, adhere well to pedicel. Skin rather thin, tough, adheres strongly to pulp, contains but little pigment, not very astringent. Flesh pale green, translucent, tender when ripened under favorable conditions, stringy, vinous, pleasant-flavored, sweet next the skin, agreeably tart at center, above average quality. Seeds slightly adherent, one to five, average three, nearly large to medium, usually long, of mean breadth, deeply notched, rather blunt but often with slightly enlarged neck, brownish; raphe usually obscure, sometimes showing as a faint ridge in a broad groove; chalaza nearly small, pear-shaped or circular, above center, distinct.
