(ChinaDaily) - Metropolitan cities like Beijing and Shanghai are seeing a lot of wine-tasting events, organized by major wine-producing countries. But recently the agricultural trade office of the US embassy chose to hold an American wine tasting in Zhengzhou, capital of Henan province. More than 400 people, mostly industry insiders, attended the wine tasting on July 10. The number of attendees was twice the initial expectation. "I was told that almost 80 percent of wine industry players from Zhengzhou showed up," says Ma Zhen, editor-in-chief of Wine in China, which co-sponsored the event.
