Located on the pied de côte (foot of the slope) south of the medieval village of Saint-Émilion, Château Canon La Gaffelière's terroir consists of clay-limestone and clay-sand soil that is very permeable and particularly efficient at retaining heat.

The choice of grape varieties is rather atypical for the appellation in light of the soil: almost a perfect 50/50 divide between Merlot and Cabernet. The Cabernets ripen early and remarkably well on Canon La Gaffelière's warm soil, adding power and aromatic complexity to Merlot's opulence to create wines of natural elegance and finesse.
