The reds are dominated by the Cabernet Sauvignon variety (66% of the cultivated surface), the variety of choice in the Médoc, particularly in Saint Julien. This variety provides tannic structure and power. With 30% Merlot, the wines become rounder and more suave.

To improve this alchemy of varieties and terroirs, the petit-verdot (4%) provides a delicate touch, like spices in fine cuisine. A difficult variety to tame, it can prove an incredible asset in outstanding vintage years. It is particularly pampered at Talbot, as Nancy Bignon-Cordier has a weakness for this enfant terrible.

For the whites, the grape variety is composed of 80% Sauvignon and 20% Semillon.
