Vine vigorous to medium, hardy, medium to productive, inclined to mildew. Canes intermediate in length, numerous, of average thickness, covered with considerable blue bloom; nodes enlarged, flattened; internodes short to medium; diaphragm thick; pith about medium size; shoots glabrous; tendrils intermittent, rather long, trifid to bifid. Leaf-buds large, long, rather thick, conspicuous, obtuse to conical, open in mid-season. Young leaves heavily tinged on under side and lightly tinged along margin of upper side with bright carmine. Leaves medium to large, of average thickness; upper surface rather dark green, glossy, smooth to medium; lower surface pale green, not pubescent; veins distinct; lobes usually three in number with terminal lobe acute to acuminate; petiolar sinus medium to deep, variable in width; basal sinus usually lacking; lateral sinus shallow to medium, rather narrow or often a mere notch; teeth inclined to shallow, usually above medium in width. Flowers sterile, open in mid-season; stamens reflexed. Fruit ripens before mid-season, keeps frequently until late winter. Clusters of average size, long to medium, rather slender, slightly tapering to cylindrical, often with a long, loose, single shoulder, variable in compactness; peduncle medium to long, of average size; pedicel somewhat short, rather slender, covered with few small warts, wide at point of attachment to fruit; brush short, stubby, pale green. Berries medium in size, roundish to frequently compressed, black, glossy, covered with abundant blue bloom, persistent, firm. Skin intermediate in thickness, tough, rather adherent to the pulp, contains a moderate amount of wine-colored pigment, slightly astringent. Flesh somewhat dark green, juicy, fine-grained, nearly tender, stringy, not foxy, rather spicy and aromatic with Aestivalis flavor, sweet, ranks good or higher in quality. Seeds adhere slightly to the pulp, one to four, average three, above medium to large, rather wide, intermediate in length, somewhat blunt, plump, brownish; raphe obscure; chalaza oval to circular, slightly above center, rather distinct. Must 93°-100°. (=I=) =EUREKA.= (Labrusca.) =1.= _Mag. Hort._, =27=:6. 1861. =2.= _Gar. Mon._, =6=:371. 1864. =3.= _Mag. Hort._, =33=:205. 1867. =4.= _Am. Hort. An._, =1871=:80. =5.= _Bush.

Eureka resembles the Isabella very closely in both fruit and vine. The fruit ripens about two weeks earlier, is somewhat more tender in pulp, more compact in the bunch, and with the vine of greater vigor.
