Château Moulin Eyquem produces wine in Côtes de Bourg, the smallest and most northern appellation of Bordeaux's Right Bank. The region's clay and limestone soils yield structured reds built on Malbec, Cabernet Sauvignon, Cabernet Franc, Merlot, and Petit Verdot—a traditional Bordeaux blend that balances power with finesse. The winery's Côtes de Bourg reflects the appellation's character: wines with depth and aging potential, less opulent than their Pomerol and Saint-Émilion neighbors but marked by mineral precision and tannin architecture. Wine Enthusiast and Decanter have assessed the wines.
