Château Larcis Ducasse is a prestigious Saint-Émilion Grand Cru from Bordeaux, France, produced by the Gratiot Alphandery family estate. The wine is classified as a Saint-Émilion Premier Grand Cru Classé B, one of the Right Bank's most celebrated appellations.

The vineyard spans 11.3 hectares and is planted to approximately 83–86% Merlot and 14–17% Cabernet Franc, with vines averaging 35 years of age. The estate practices 100% organic farming since the 2005 vintage. Grapes are whole-berry fermented in traditional cement tanks with pigeage, followed by 25–28 days of maceration. The wine is aged 18–20 months in 67% new French oak barrels of mixed sizes, including 500-liter casks and a small portion in amphora. Production averages approximately 4,000 cases per vintage.

The wine is known for its rich, mineral-driven character with aromas of dark cherries, blackberries, licorice, crushed stone, and floral notes. On the palate it delivers opulent, layered fruit with silky tannins and a long, persistent finish. It is best decanted for 2–3 hours when young and typically reaches peak maturity 12–35 years after the vintage. Serve at approximately 15.5°C (60°F).

Pairs well with classic meat dishes including beef, lamb, duck, veal, pork, and game, as well as roasted and braised preparations, hearty fish such as tuna and salmon, mushrooms, pasta, and a wide range of hard and soft cheeses.
