Using red grape varieties(Vitis amurensis, Merlot, Zuo youhong, Bei binghong and Cabernet Sauvignon) and white grape varieties (Chardonnay, Vidal, Riesling, Ugni blanc) as raw material, the physicochemical properties of 10 grape samples of different varieties and planting years were analyzed. The single grain weight, fruit size, total soluble solids, total sugar, total acid, sugar-acid ratio, total phenols and tannin content were determined and compared. There were differences on the content of different substances in different varieties of wine grape. The red grape varieties (Merlot, Cabernet Sauvignon) and white grape varieties (Vidal, Riesling) showed high quality, such as higher sugar-acid ratio, total phenols and tannin content, which were suitable for cultivating at Jiayuguan Zixuan vineyard.
