Chateau Boyd-Cantenac is a wine producer situated in the Margaux appellation on the left bank of Bordeaux. The estate's Cabernet Sauvignon-dominant grand vin was awarded third growth status in the 1855 Classification of Médoc and Graves. Boyd-Cantenac's main Médoc vineyard (which covers 42 acres) is planted predominantly to Cabernet Sauvignon, with Merlot, Cabernet Franc and Petit Verdot also featuring in the grand vin. The grapes are harvested by hand and are fermented and barrel-aged individually by block.
