 Long viewed as the leading "cru" of Moulis, the estate's viticultural history is documented back to 1560, and possibly before.Initially an estate named Grand-Poujeaux, it was owned by the "seigneurs" Grenier, which may have evolved into Gressier.The estate was divided in 1822 due to inheritance complications, with half the property becoming Château Gressier-Grand-Poujeaux, and the remainder being passed to the Castaing family.
