(AFP) - Bordeaux is spoiled for choice as it unveils the 2010 vintage, its third smash hit in six years, in a week of barrel tastings for wine professionals from around the world. "It's liquid beauty," said Denis Dubourdieu, a consulting winemaker and director of the Institute of Vine and Wine Sciences (ISVV) at the University of Bordeaux.In a system unique to Bordeaux, each spring the region's chateaux offer trade-only tastings that kick off the futures -- or "en primeur" -- campaign, in which the wines are offered for sale roughly two years before delivery.
