Grapes are one of the oldest and most widely distributed fruits in the world, and humans have been cultivating this fruit tree for a long time, accounting for almost a quarter of the world's fruit production; its nutritional value is so high that it can be made into grape juice, raisins and wines. Large grains, thick skin, less juice, more water, easy separation of skin and flesh, sweet and sour taste, storage-resistant Eurasian grapes also known as, generally grow in clusters, yellow-green, red, black-blue or purple. The flesh has a thin skin on the outside, a thin frost on the outside of the skin, and the grapes are called "crystal pearls" because of their bright colors, delicious taste, and high nutritional value.
