China 'driving global wine market'
Hong Kong's wine auction market is becoming more sophisticated, with local buyers more knowledgeable about the wine itself, and how to buy it.
"It's a healthier and more discerning market [now]," Robert Sleigh from Sotheby's tells the BBC.
In fact, he says, Greater China as a whole is driving the international market for top end wines.
