Château Larcis Ducasse is a historic French wine estate in Saint-Émilion, classified as a Premier Grand Cru Classé B. Situated on the south-facing slopes of the Saint-Émilion plateau (Côte Pavie), the estate produces rich and elegant wines that express the unique clay-limestone terroir. Owned by the Gratiot-Attmane family since 1893, the château underwent a major quality renaissance beginning in 2002 under the direction of Nicolas Thienpont and consultant Stéphane Derenoncourt.
