Château Trianon produces wines across Bordeaux's classic appellations, anchored by a Saint-Émilion Grand Cru built on Merlot, Cabernet Sauvignon, Cabernet Franc, and Carménère. The Pavillon de Trianon Bordeaux blends Cabernet Sauvignon, Petit Verdot, Malbec, Cabernet Franc, and Merlot into a structured expression of the region's traditional style. The portfolio extends to a Côtes de Provence Rosé, a Grenache and Cinsault blend that shifts the house's focus southward. Wines from Château Trianon have been assessed by Wine Advocate, Decanter, Wine Enthusiast, and Falstaff. The Saint-Émilion Grand Cru and Pavillon de Trianon Bordeaux represent the core of the winery's output, with the rosé offering a lighter counterpoint to the red-wine emphasis.
