Grow them only in southern New Mexico. American Grapes Vitis labrusca are used mainly for juice. These grapes are more cold hardy and more resistant to some disease and insect pests than European grapes. These hybrids are produced by crosses between the American and European types. French Hybrids Crosses between the European and wild-American grape.
Some cultivars produce good wine while others are acceptable as table grapes.
Hybrid types, in general, are intermediate in winter hardiness between American and European species. Most European varieties are not winter hardy. Varieties such as 'Black Monukka', 'Cabernet Sauvignon', 'Emerald Riesling', 'Pinot Chardonnay', 'Thompson Seedless', and 'White Riesling' failed to survive winter conditions or had poor plant vigor in northern New Mexico. Concord' being the most sensitive 'Fredonia', 'Niagara,' and 'Westfield' cultivars have performed better in northern New Mexico. Following are descriptions of some American and French hybrid cultivars that have performed acceptably in north-central New Mexico.
