BORDEAUX — Chinese wine buyers arrived in record numbers during the professional tasting for the 2009 harvest in Bordeaux and Chinese investors are also increasingly interested in buying the vineyards. Some professionals said that rising Chinese demand will further fuel the price speculation that has already priced many top Bordeaux wines beyond the reach of the average wine lover. Last year, China became the biggest export market outside the European Union for Bordeaux wines in volume, ahead of the US. There are several vineyards in China, some created with help from French specialists, but the well-to-do Chinese wine lover prefers the real thing from France.
