By the late 90s the selection processes for Pavillon Rouge had become increasingly rigorous leaving the Château with an entire third selection of grapes. Still it took over a decade to determine that the quality of that fruit could provide an opportunity to bottle a third wine that still met the high standards of the Château. Margaux de Château Margaux was born in 2009. Now, we see the finest selection go to Château Margaux, and then to Pavillon and Margaux de Château Margaux, with still a fourth selection being sold off. The estate explains the orgins of the 2013 vintage: "We decided to 'support' the Margaux de Château Margaux with some very good batches which had been earmarked for the Pavillon Rouge, and at the same time, we relegated nearly a quarter of the production to the fourth selection. We thought that the Margaux du Château Margaux would be blended from the relegated batches, when in fact it is completely composed of wines that used to go into the Pavillon Rouge, which left the quantity sold in bulk unchanged. Therefore Margaux du Château Margaux 2013 benefits from the extreme selection carried out on the Pavillon Rouge (which only represents 21% of the harvest), and from the removal of the least successful plots (all of which went into the fourth selection sold in bulk). The Merlot makes up only 12% of the blend, putting the emphasis on the Cabernet Sauvignon which was the main success of the vintage (88% of the whole)."
