Black Corinth Grapes
Black Corinth (aka Zante Currant, the Champagne grape, etc.). An ancient grape, probably of Greek origin. While the main variety is black, there are red and also white forms of the grape, though they are less common than the black form. One of only a very few parthenocarpic grapes in commerce. Other grapes are seedless because the seeds start to develop, then abort. Parthenocarpic grapes have no seed development at all. Black Corinth has the smallest berries of all seedless grapes and must be sprayed with hormone, or have the vine girdled for the berries to set evenly and have any size to them at all. Without treatment, the berries are mostly pinhead size. Very susceptible to powdery mildew, even for a vinifera grape. The name "Champagne Grape" comes from a pictorial in Sunset magazine. Written by Allan Corrin, a produce dealer whose company grows most of the Black Corinth sold in stores in the U.S., it showed a frosted bunch of Black Corinth with a glass of champagne. In actuality, there is an old American grape already named "Champagne" that is a very coarse, harsh tasting labrusca grape. Prune Black Corinth to canes for best production.
