Bordeaux - Zhizie Wu has come a long way since he first sipped - or rather chugged - a glass of wine. Back then it was mixed with soda.
Now, after two years in the French city of Bordeaux, the 23-year-old Chinese student can distinguish different varieties of grapes just by swirling a glass under his nose.
Wu is part of a young crop of Chinese flocking to the southwestern region, France's largest wine-growing area, to train for careers in the wine trade - a burgeoning industry in China.
