Château Grand-Puy-Ducasse is a French winery in the Pauillac appellation of the Bordeaux region of France.
Château Grand-Puy-Lacoste is a French winery in the Pauillac appellation of the Bordeaux region of France.

Note: The correct name of the Château is actually Château Grand-Puy-Lacoste, not Château Grand-Puy-Ducasse. I provided a synonym with the correct name to maintain accuracy.
