(PaulFraserCollectibles) - Values for leading Bordeaux wines are up 3.36% since the start of the year, according to figures from the Liv-ex Fine Wine 50 Index. The positive numbers for the "Blue Chip" of the wine collecting world are indicative of the health of the word's wine markets, and provide considerable excitement to potential buyers. Sotheby's recent monumental wine auction in London is a prime example of the market's strength, with a £28,200 six-magnum lot of Chateau Le Pin 1990 highlighting the Bordeaux offerings, while a case of Petrus beat its £10,000 estimate by 23.3%, with a £12,338 showing.
