Li Dehui, 31, works at a foreign corporation in Beijing and visited a winery near Barcelona in Spain last year. He toured the vineyard and checked out the cellar storage and workshops.

"It's a great experience to see the whole production process of wine," Li says.

"I also learned that the more grape leaves and seeds are kept during processing, the rougher the wines will be. Also, the wines I tried were very tasty and much cheaper than those in China."
