Grapes come in different colors and forms. There are red, green, and purple grapes, seedless grapes, grape jelly, grape jam and grape juice, raisins, currents, and sultanas, not to mention wine. Up to 8,000 years ago, people first cultivated grape vines in what is now the Middle East. Today, 72 million tons of grapes are grown each year worldwide, mostly to produce wine. Every year, 7.2 trillion gallons of wine are produced. Grapes are also a popular finger food.
