The Concord grape is a cultivar derived from the grape species Vitis labrusca (also known as 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 sacramental and kosher wine. Traditionally, most commercially produced Concord wines have been finished sweet, but dry versions are possible if adequate fruit ripeness is achieved. The grape is named after the town in Massachusetts where it was developed. The grapes are cultivated in many different parts of the world now.
The skin of a Concord grape is typically dark blue or purple and often is covered with a glaucous epicuticular wax "bloom" that can be rubbed off. It is a slip-skin variety, meaning 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 spot.[2]
In the United States, 417,800 tons were produced in 2011.[3] The major growing areas are the Finger Lakes District of New York, Lake Erie, Lake Ontario, Southwestern Michigan, and the Yakima Valley in Washington.[4] They are sometimes found growing wild.
Concord grapes are often used to make grape jelly and are only occasionally available as table grapes,[5] 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. 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.[6] Concord grapes have been used to make kosher wine[7] and sacramental wine. The oldest sacramental winery in America, O-Neh-Da Vineyard, still produces a Concord wine for the altar.[8]
The Concord grape was developed in 1849 by Ephraim Wales BullinConcord, Massachusetts.[9] Bull planted seeds from wild Vitis labrusca and evaluated over 22,000 seedlings before finding what he considered the ideal Concord grape.[9] Genetic testing confirmed that Concord grape has roughly one-third Vitis vinifera parentage.[10] The selected Concord vine was planted next to other cultivars, including Catawba, which was later confirmed to be a parent of Concord using systematic SSR analysis.[1]
In 1853, Bull's grape won first place at the Boston Horticultural Society Exhibition.[9] It was then introduced to the market in 1854. Dr. Thomas Bramwell Welch developed the first Concord grape juice in his house in 1869.[9] Through the process of pasteurization, the juice did not ferment.[9] Welch transferred the juice operations to Westfield, New York, processing 300 tons of grapes into juice in 1897.[9]
