Only 10 percent of China's vineyard dedicated to vinifera varietals

The widespread practice among Chinese wine companies to blend imported bulk wine into domestic products has driven the flow of bulk wine into China.
 
The volume and volatility of trade indicates the highly variable volume and limited quality of domestic wine production. In fact, it is estimated that only roughly 10% of China’s 450,000 ha vineyard estate is dedicated to vinifera varietals. Price determines who supplies the bulk market from year to year, and while Chile and Australia have historically supplied large volumes, Spain and Italy met the market in 2010.
