Each of the 112 parcels is planted with a specific grape variety including Merlot, Cabernet Franc, Chardonnay, Cabernet Sauvignon and Petit Verdot. The estate is keen to preserve its biodiversity. It was one of the first estates to produce an unfiltered wine. Its unfiltered Chardonnay has become a genuine star.
