The winery's portfolio centers on Merlot and Cabernet Sauvignon blends, with Cabernet Franc adding structure and complexity to select offerings. Elite Blaye, a Cabernet Sauvignon and Merlot blend, represents the winery's upper tier, while Diamant Rouge combines all three Bordeaux varietals in a more nuanced expression. Authentique de Bertrands showcases Merlot as the sole varietal.
