Château Marquis d'Alesme is an estate located in the Margaux appellation of the Médoc. It was classified as a third growth in the original 1855 Bordeaux Classification of the Médoc and today produces a Cabernet Sauvignon-dominant grand vin, and a second wine.The vineyards are characterized by gravel-rich soils mixed with sand, clay and limestone. The sun-exposed slopes are cooled by the nearby Gironde estuary, providing the perfect growing conditions for vines. Cabernet Sauvignon dominates the vineyards, closely followed by Merlot and smaller quantities of Petit Verdot and Cabernet Franc. The estate employs sustainable viticultural techniques and takes an organic and biodynamic approach to vine-growing.
