Concord grapes (Vitis labrusca), or fox grapes, are fruiting berries that grow in clusters on woody, climbing vines. Native to eastern North America, they are more aromatic than other grapes due to their unique strong ""foxy"" musk aroma, and they are commonly used for making wines, juices and jams.

Like other blue and purple fruits, concord grapes contain abundant polyphenols such as flavonoids like resveratrol and other compounds like hydroxycinnamic acids, catechins and methyl anthranilate, the aromatic compound responsible for the concord grape’s unique aroma and flavor. They also contain moderate amounts of vitamin C and potassium.*
