(Harpers) - Fine wine prices retreated 7.5% in the third quarter of the year, pointing to a "market correction" according to Bordeaux Index.

Among the biggest victims of the slumping market have been many of the prestigious First Growth wines from ‘blue chip' vintages that have shed up to a third of their price - along with selected 2008 wines that were inflated during a series of well-publicized auctions last November. Founder and managing director, Gary Boom, said: "There's definitely a market correction going on - the numbers don't lie.
