Château Rollan de By sits in the Médoc, Bordeaux's left-bank stronghold of structured red wines. The estate produces a Médoc blend of Merlot, Cabernet Franc, and Cabernet Sauvignon—the classic Bordeaux trio—alongside a crisp Sauvignon Blanc called Le Blanc and a dry rosé built from Cabernet Sauvignon and Merlot. These wines have been assessed by Wine Advocate, Wine Enthusiast, Decanter, and Wine Spectator. The Médoc and Le Blanc both earned an average prestige rating of 88.0, while the Bordeaux Rosé reached 86.7, reflecting the range of the winery's output across red, white, and pink expressions.
