Chateau Boyd-Cantenac was bought by Pierre Guillemet in 1932. By this time, he was already an experienced winemaker and owned another mansion in the Margaux appellation, Chateau Pouget. The family still manages both properties, and are now cared for by Pierre's son, Lucien. The 17 hectares of vineyards are planted with 60% Cabernet Sauvignon, 25% Merlot, 8% Cabernet Franc and 7% Petit Verdot. The wine matures for 12-18 months in barrels, of which 50% is new oak. Boyd Cantenac usually reaches maturity after 5-10 years, but it is nice and younger if you let it breathe for an hour or two. The winery sells most of its wine through non-traders and labels and bottles only about 10%.
