Château Ducru-Beaucaillou is a winery in the Saint-Julien appellation of the Bordeaux region of France.
The Chateau has since corrected the problem, and today the wines are fermented and aged in a new underground cellar created in the late 1990s.
Ducru-Beaucaillou's vineyards consist of 50 hectares of well-drained gravel with stones up to 2.5 inches in diameter.
The grand vin, called Château Ducru-Beaucaillou; a second wine, La Croix de Beaucaillou, produced since 1995, to which lesser-quality lots are relegated; and a third wine, Le Petit Ducru de Ducru-Beaucaillou, produced since 2019, comprising the former Château Lalande-Borie.
[1] The wines are aged for 18 months in 50% to 80% new oak barrels according to the richness of the vintage, fined with egg whites, lightly filtered, and then bottled.
