(Decanter) - Interest in Burgundy and beyond continues to rise in the fine wine auction market. The latest sale at Sotheby's London (22 February) suggests Asian collectors' appetite for Domaine de la Romanee Conti and top Burgundies is insatiable. A single bottle of DRC's Romanée Conti 1962 sold for £9,400, more than double the high estimate, while esteemed producers including Rousseau attracted high bids. The northern Rhone also had an encouraging day: six bottles of Guigal's Côte Rôtie, La Mouline 2000 sold for £1,586 - nearly double the high estimate – suggesting further diversification in the fine wine market.
