When do grapes in southern China generally ripen?

Everyone knows that grapes are highly nutritious and sweet and tasty, and many people love to eat them! Ordinary households will buy some at a time and keep them at home to eat slowly. So in what season do grapes in southern China ripen?

Grapes are a fruit of late summer and early autumn, and their approximate ripening time is around July to October. Depending on the growing region, the ripening time also differs somewhat; in southern China they ripen relatively earlier, reaching maturity around June and July, while in the Xinjiang region they ripen in August and September. Also, the variety grown affects the ripening time; there are early-ripening and late-ripening varieties with different maturation periods, but they are basically on the market around July and August.

But shopping malls sell grapes year-round; after all, humans are clever and know how to grow grapes in greenhouses, and the different climates of various places plus efficient transport also mean grapes can be eaten in any season.
