Despite the beauty and timelessness of the building structures, it is the vineyard for which the domaine is best known. The Savennieres from Epire is regarded as Grand Cru. The domaine works primarily three parcels: La Croix Picot, Le Parc, and Le Hu-Boyau. It is the latter that sits just above another famous vineyard, La Coulee de Serrant. The soils here are rich, and the microclimate is ideal. Southern and south-eastern sun exposure brings ripeness to the grapes, while the proximity to the Loire River keeps the temperatures moderate. The subsoils are comprised of sandstone and schist, and the top soil is a beautiful blue slatey schist that covers the vineyard floors, lending nerve and firmness.
