Château Caillou produces Sauternes in Bordeaux's celebrated sweet wine region. The winery's portfolio centers on Sémillon-based expressions, with the Cuvée Prestige Sauternes anchoring its range. A blend of Sauvignon Blanc and Sémillon forms the Cuvée Reine, while Les Erables de Caillou rounds out the lineup as a Sémillon offering. Sauternes demands precision in the vineyard and cellar—noble rot must be managed carefully, and botrytized fruit demands gentle handling to preserve complexity without excess. Château Caillou's wines have been assessed by Falstaff, Wine Advocate, Wine Spectator, and Wine Enthusiast, reflecting the region's standing among serious collectors and critics.
