Commercial production of grapes dates all the way back to the year 1000 B.C. It was not until the year 1854 that the Concord variety came into being. The Concord grape is named after the Massachusetts village of Concord where the first vines were originally cultivated. The Concord grape is an extremely robust and aromatic grape derived from wild native species growing throughout New England in the most rugged soils. Grape juice and grape jellies and jams are long-time favorites of children and adults alike. These products contain natural carbohydrates that are easily digested and provide instant energy. America's favorite grape juice and grape jelly come from Concord grapes. Concord grape juice, jams and jellies are low in sodium and contain no fat or cholesterol. One cup of 100% Concord grape juice contains 75% of the potassium of a banana. As with other natural fruit products, Concord grape juice contains a variety of naturally occurring vitamins and minerals. Recent research on phytochemicals has focused on flavonoids contained in Concord and other purple grape juice. These flavonoids, which were initially identified in research on red wine, are naturally occurring compounds that are thought to reduce the "stickiness" (or clotting characteristics) of platelets found in the blood. Platelet stickiness is a contributor to clotting which can give rise to a heart attack or stroke.
