Jean-Guillaume Prats, then head of estates & wines for Moët Hennessy, once got snowbound for three days while visiting vineyards 2500 meters (8200 feet) up in the mountains of Yunnan, where European missionaries first planted grapes in the 19th Century and the company now makes a wine named Ao Yun that some critics rate as China's best.

Now, where to get a bottle?
