The estate extends between Saint-Émilion and the heights of Saint-Christophe-des-Bardes. On the clay plateaus of the appellation, its vines, mainly composed of Merlot, were planted in 1945.

After harvesting by hand, the wine is worked so that it can be enjoyed from its young years, while ensuring optimal maturation over time.

Only 2000 bottles of Grand Cru Château Marrin are produced each year.
