Château La Croix Lartigue produces wines from Bordeaux, drawing on the region's classic blend of Merlot, Cabernet Sauvignon, and Cabernet Franc. The winery's Castillon – Côtes de Bordeaux combines these varieties into a structured wine that has attracted attention from Wine Spectator, Decanter, Wine Enthusiast, and Wine Advocate. L'Expression de La Croix Lartigue, the winery's second offering, blends the same grapes in a different proportion, presenting an alternative expression of the terroir. Both wines reflect the Right Bank's preference for Merlot-forward compositions, tempered by the structure and aging potential that Cabernet varieties bring to Bordeaux blends. The winery operates within a region defined by its maritime climate and clay-limestone soils, conditions that shape the character of wines across the appellation.
