  • The old favorite blue-black grape was developed in 1849 by Ephraim Bull in Concord, Massachusetts. Bull evaluated over 22,000 seedlings before finding what he considered the perfect grape, the original vine of which still grows at his former home. In 1853, Bull's grape won first place at the Boston Horticultural Society Exhibition. It was then introduced to the market in 1854. Dr. Thomas Bramwell Welch developed the first Concord grape juice in 1869. Through the process of pasteurization, the juice did not ferment. Welch originally introduced the grape juice to his church, to be used for communion.
    Concord 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. The skin of a Concord grape is typically dark blue or purple, and often is covered with a lighter colored "bloom" which can be rubbed off. It is a slip-skin variety, meaning that the skin is easily separated from the fruit.
