The history of this château is closely linked to that of the Dordogne, the mighty river that runs just in front of the domaine. The Dordogne was formerly used to transport wines towards Bordeaux in boats called 'Gabarre' and the name Grandefont is derived from the 'grand fountain' as this place was a key point for boatmen.
The domaine currently covers 45 hectares of vines planted predominantly with the merlot varietal. The vines thrive in their gravel and sand soils. The vineyard lies on a former riverbed and the soils are composed of small stones which retain heat during the day in order to pass it back to the vines at night.
