What is Grapes?
Grapes are small, round, and juicy fruits that grow in clusters on woody vines belonging to the Vitis genus. They come in various colors such as green, red, purple, blue, and black. Grapes can be eaten fresh, dried into raisins, or processed into wine, grape juice, and vinegar.
Cultivation of grapes dates back over 6,000 years, with origins in the Middle East. Today, grapes are grown worldwide, with the largest producers being Italy, Spain, China, and the United States.
There are two main categories of grapes:
- Table Grapes – Typically seedless, eaten fresh, and enjoyed as snacks.
- Wine Grapes – Smaller, with seeds and thicker skins, used for winemaking.
Grapes are not just delicious; they are also considered a functional food because of their high content of antioxidants like resveratrol, flavonoids, and polyphenols, which promote long-term health.
