Chinese green raisins producing area is only at Turpan, Xinjiang. Since August, green raisins began to come to market, but during this time, the green color is not very green and not stable, would fade easily. In September, most of green raisins would be available and have best quality. The green color would be greenest and more stable. The best time to buy Chinese green raisins Is from September to Novemver.
