Château d'Arce sits in Castillon–Côtes de Bordeaux, the Right Bank appellation known for structured, fruit-forward reds built on Merlot and Cabernet Franc. The region's clay-limestone soils and Atlantic-moderated climate produce wines with supple tannins and dark-fruit character. The winery's Castillon–Côtes de Bordeaux blend draws on these terroir strengths, balancing the plush mid-palate of Merlot with the herbal spine and grip of Cabernet Franc. The wine has earned recognition from Decanter, Wine Spectator, and Wine Enthusiast. Castillon remains one of Bordeaux's less-heralded appellations, offering the region's classic structure and aging potential at a more measured price point than its Left Bank neighbors.
