(Reuters) - It was a good year for fine wine in 2011 with auction houses reporting solid sales but the bubble has burst in the Bordeaux market and prices are expected to fall further in 2012. Wine sales at auction house Acker Merrall & Condit topped $110 million this year. Christie's estimated its sales would be more than $90 million, while Sotheby's wine auctions hit $85.5 million and Bonhams finished at $17 million.
