Certified Biodynamic (property of Chateau Le Puy).
The Amoreau family acquired this nine-hectare vineyard in 2006, and immediately began employing biodynamic practices (Duc des Nauves is certified biodynamic as of the 2015 vintage). Planted to 70% Merlot, 20% Cabernet Franc, and 10% Cabernet Sauvignon, the vineyard is situated on the same Asterie-limestone mother rock as those of Le Puy, but at a slightly lower altitude (80 meters above sea level compared to Le Puy's 110 meters). The topsoil is slightly sandier and less clayey here, and it is a bit deeper than at Le Puy (between 1.0 and 1.3 meters). In the cellar, Duc des Nauves is both fermented (spontaneously, of course) and aged in cement, and bottled without filtration after one year.
