Château Margaux is one of Bordeaux's most famous wine estates, located just east of Margaux itself in the Médoc. Along with Lafite, Latour and Haut-Brion, it was rated as a first growth in the original 1855 Bordeaux Classification of the Médoc. Generally, Margaux is considered as the most elegant of the first growths, and is consistently one of the most expensive wines in the world. The Cabernet Sauvignon-dominant blend is complimented with small portions of Merlot, Petit Verdot and Cabernet Franc. Vineyards Château Margaux's vineyards have a complex combination of soils that are unique to the area. These consist of chalky clay under a top layer of coarse and fine gravels, which is well-suited to Cabernet Sauvignon, which accounts for around 75 percent of plantings. Merlot makes up a further 20 percent, with the rest planted to Cabernet Franc and Petit Verdot. As is typical for top Bordeaux estates, the vineyard is densely planted at 10,000 vines per hectare. There are also 12 hectares (30 acres) of Sauvignon Blanc to make Margaux's white offering, Pavillon Blanc, which must be sold as Bordeaux AOP, not Margaux. This compliments the Pavillon Rouge the second wine of which production dates back to the beginning of the 16th Century. History La Mothe de Margaux existed as a distinct property in the 12th Century, and was set up as a wine estate in the 1570s, as farmers in the Médoc began to abandon cereal crops in favor of vines. In 1705, the London Gazette advertised the first auction of 230 barrels of "Margose", and in 1787, Thomas Jefferson made his famous visit to Bordeaux and identified Margaux as one of the "four vineyards of first quality". By 1800, the estate occupied 265 hectares (655 acres) with a third planted to vines, which remains the situation today. The iconic neo-palladian château, nicknamed "The Versailles of the Médoc", was built in the early 1800s to match the reputation of the vineyard. In 1977, Château Margaux was bought by the Greek-born cereals trader and grocery chain owner André Mentzepoulos. In a time of economic crisis he began a major program of investment, which was continued upon his death in 1980 by his daughter Corinne and winemaker Paul Pontallier (who joined in 1983). This overhaul allowed Margaux to fully benefit from global economic upturns and the excellent 1982 vintage.
