A rare Burgundy has emerged as the world's most expensive wine at more than USD 15,000 a bottle, and it is not a Romanee-Conti, according to the WineSearcher website. Instead it is a Henri Jayer wine with the USD 15,195 price tag, and Bordeaux's top-of-the-line Petrus is far down the list at 18th place. It is a 1985 Richebourg Grand Cru created by Jayer, a winemaker widely considered a visionary in the business who died in 2006 aged 84.
