Grapes are really berries that grow in bunches on long, twining vines that can produce up to 50 bunches per season. Grapevines can produce for up to 60 years or longer. In winemaking, vines are meticulously pruned to limit the number of grapes, thus intensifying the flavor of the wine. Grapes appear in Greek and Roman mythology with the invention of wine, and its intoxicating properties are associated with the god Dionysus (Roman name, Bacchus). Wine was first regarded as a sacred beverage and it remains steeped in symbolism today in many Christian churches. Varieties Grapes are often classified according to their use as table or wine grapes. Vitis vinifera, grown in Europe and considered the ideal grape for wine production, encompasses thousands of types. Vitis labrusca and Vitis rotundifolia are primarily found in North America and include the Concord (dark purple to black) grape, which is used both as a table grape and to make juice, jellies, and wine. Another popular grape variety in U.S. markets is the pale green Thompson seedless grape, a variety that accounts for half of the table grapes grown in California, and that is also used to make over 90 percent of the raisins in the United States. Other popular table grape varieties include Cardinal (red), Emperor (bright red), Flame seedless (red), Niagara (green), Catawba (red), and Ribier (jet black). Buying and storing tips Choose bunches that are somewhat tight, with fresh stems, grapes firmly attached, and skins intact and without mushy spots. Avoid mold-spotted, wrinkled, raisinlike, or sticky grapes. They do not ripen after harvest. Store grapes refrigerated as they are ripe when they are picked, and warmer temperatures will cause them to wither or ferment. Under refrigeration, grapes will keep for up to two weeks. Keep grapes on their stems, washing them only at the last minute before serving, then blot them dry. Availability Grapes are available year-round, with those grown in the United States peaking from mid-June to November. Preparation, uses, and tips Grapes can be attractive additions or centers of attention in fruit salads, tarts, curries, and jams. When carefully dried, they become raisins. Grapes can be crushed as a dessert topping. They can also be juiced for a refreshing treat.
