Even in the Gallo-Roman period, the vineyard «Château Tayac» was noted and appreciated for the quality and finesse of its production, thanks to its southern exposure and the nature of its clay-limestone soil, although difficult to work with, but great nobility. The vineyard, located 54 m above sea level, benefits from a microclimate.
The proximity of the river preserves the vines from spring frosts.
The only farm of 30 hectares is oriented to the southern slopes overlooking the confluence of the Dordogne and the Garonne: Gironde.
The soil is thin: 0.30 to 080m on limestone.
The terroir is difficult to work with, but contributes to the quality and finesse of the wine.
