TERROIR PROFILE

Castillon & Francs Côtes de Bordeaux

Clay-limestone slopes in Saint-Émilion's shadow

The same limestone slopes as Saint-Émilion at a quarter of the price: Castillon and Francs are Bordeaux's best-kept Merlot secret.

Climate, site & wine

Limestone and clay, in places with marl, form the same soils as in the famous neighbour. Merlot dominates, with Cabernet Franc and Cabernet Sauvignon adding structure and spice; the limestone soils ensure freshness.

The wines are powerful and fruit-driven, with dark cherry, plum and spice, firm but mostly ripe tannin. The best sites yield blends with chalky freshness and ageing potential, overall more approachable and rustic than in Saint-Émilion.

Marlbalanced, structured

Marl is a mix of limestone and clay — yields structured, balanced wines with acidity backbone.
