Which US native wild grapevine species is known as Concord?

The Concord grape is indeed derived from the species Vitis labrusca. This grapevine species is native to the northeastern United States and is particularly known for its distinctive flavor profile, often associated with a sweet and fruity character. Concord grapes are commonly utilized in the production of grape juice, jellies, and wines, and they have become a staple in American vineyards.

Vitis labrusca is prominent for its hardiness and adaptability to various climates, making it favorable for cultivation in many regions across the U.S. The grape’s skin has a characteristic "slip-skin" texture, which allows the outer skin to detach easily from the flesh when eaten. This trait, combined with its unique taste, contributes to its popularity among consumers.

In contrast, the other species mentioned have different characteristics and uses. Vitis vinifera is known for producing most of the world's wine grape varieties, but it is not a native species in the U.S. Vitis rotundifolia, commonly known as muscadine, is celebrated for its unique flavor and is primarily grown in the southern United States. Vitis aestivalis, also a native species, is used for making wine but does not have the same widespread recognition or popularity as Vitis
