J. H. Ricketts of Newburgh, New York, produced Eldorado some time about 1870 from seed of Concord fertilized by Allen's Hybrid. It was introduced by the originator about 1881 and is still offered for sale by a few nurserymen. Eldorado has been somewhat commonly grown in gardens and collections in the East but does not succeed in the West. Vine usually a strong grower, hardy except in severe winters, an uncertain bearer. Canes long, not very numerous; tendrils intermittent to rarely continuous, bifid to trifid. Leaves below medium to large, irregularly roundish, dark green, rugose on older leaves; lower surface tinged with bronze, pubescent. Flowers sterile, open medium late; stamens reflexed. Fruit ripens earlier than Concord, keeps well. Clusters do not always set perfectly and are quite variable in size, frequently single-shouldered, not uniform in compactness. Berries large to medium, roundish, yellowish-green changing to a golden yellow, covered with thin gray bloom. Flesh tender, slightly foxy, sweet from skin to center, mild, high flavored, good to very good in quality. Seeds intermediate in size and length, blunt. ELSINBURGH.

ELSINBOROUGH (6). _Elsinborough_ (2, 3, 4). _Missouri Bird's Eye_ (8). _Smart's Elsinburgh_ (3, 4). _Smart's Elsingborough_ (2, 10, 11). Elsinburgh dates back nearly a century and is now rarely cultivated, having long since been replaced by better varieties. It is certainly not known in New York now and it is doubtful if it was ever much grown as it fruits very sparingly in the North and is but half hardy in the latitude of this State. In quality it is one of the best of the Aestivalis grapes, having a pure, rich, vinous, spicy flavor without a trace of foxiness. It would undoubtedly add variety to any amateur's vineyard and might prove of value in grape-breeding, otherwise it is not worth growing; it undoubtedly makes a very good red wine.
