(Decanter) - According to the fine wine exchange Liv-ex, prices of the 100 top-traded wines, of which 95% are Bordeaux, fell by an average 22.5% between June and December last year. This was the most precipitous fall since the beginning of the recession nearly four years ago. In a shorter time period, August to December 2008, the Liv-ex 100 fell by 22%. It is top Bordeaux that is falling fastest, Liv-ex director Justin Gibbs told Decanter.com.
