Concord (grape)

The Concord grape is a cultivar derived from the grape species Vitis labrusca (also called fox grape) that are used as table grapes, wine grapes and juice grapes. They are often used to make grape jelly, grape juice, grape pies, grape-flavored soft drinks, and candy. The grape is sometimes used to make wine, particularly kosher wine. Traditionally, most commercially produced Concord wines have been finished sweet, but dry versions are possible if adequate fruit ripeness is achieved.

The skin of a Concord grape is typically dark blue or purple, and often is covered with a lighter-coloured epicuticular wax "bloom" that can be rubbed off. It is a slip-skin variety, meaning that the skin is easily separated from the fruit. Concord grapes have large seeds and are highly aromatic. The Concord grape is particularly prone to the physiological disorder Black leaf.

In the United States 417,800 tons were produced in 2011. The major growing areas are the Finger Lakes District of New York, Lake Erie, Lake Ontario, Southwestern Michigan, and the Yakima Valley in Washington.

Concord grapes are often used to make grape jelly and are only occasionally available as table grapes, especially in New England. They are the usual grapes used in the jelly for the traditional peanut butter and jelly sandwich, and Concord grape jelly is a staple product in U.S. supermarkets. Concord grapes are used for grape juice, and their distinctive purple color has led to grape-flavored soft drinks and candy being artificially colored purple while methyl anthranilate, a chemical present in Concord grapes, is used to give "grape" flavor. The dark colored Concord juice is used in some churches as a non-alcoholic alternative to wine in the service of communion. Concord grapes have been used to make Kosher wine and sacramental wine. The oldest sacramental winery in America, O-Neh-Da Vineyard, still produces a Concord wine for the altar. Non-toxic sprays that contain methyl anthranilate can be sprayed on the bushes as a cost-effective bird control management. The spray repellent renders the fruit and foliage unpalatable to the birds.
