Château La Tour de By operates in the Médoc, Bordeaux's left-bank stronghold of structured red wines. The estate produces Cuvée a Touvent Médoc, a Cabernet Franc, Cabernet Sauvignon, and Merlot blend that demonstrates the region's signature architecture of dark fruit and tannin. Héritage Marc Pagès Médoc, built from Merlot and Cabernet Sauvignon, follows the traditional Médoc formula. The winery also makes a Bordeaux Rosé from Chardonnay and Cabernet Sauvignon, offering a lighter expression. Decanter, Wine Enthusiast, Wine Spectator, and Wine Advocate have all assessed the portfolio, with Cuvée a Touvent earning particular recognition among the releases.
