It’s fitting that Sotheby’s held a fine-wine auction in Hong Kong on the holiday weekend in October that marks the founding of the People’s Republic of China.Having raised HK$107 million (US$13.7 million) with a two-day, two-part sale, the auction house has reason to celebrate the rise of demand in China, and in Asia.The wine auction is one of four Sotheby’s will hold in Hong Kong during October alone. Acker Merrall & Condit, which started wine auctions in Hong Kong in 2008, will hold six sales this year
