(2012 Vintage) Biological cultivation since 1990; biodynamic cultivation a few years later. Vine stocks: "sélection massale" (propagation of new vine stocks from a number of selected vines) done at the Drouhin nursery; also clones of recognized quality. Soil maintenance: compost of manure and white wood, sometimes guano (seabird manure used as fertilizer). Soil is ploughed either by tractor or by horse to manage spreading of weeds Treatment: only authorized products for biological cultivation are used: infusions and macerations of plant materials, sulfur and copper, powdered rock. Natural predators are not eliminated. Plantation density: from 10,000 to 12,500 stocks/ha in order to extract all possible nuances from the terroir and limit the production of each vine stock. Pruning: Guyot. Yield: we aim to keep our yields low, more in line with the previous regulation, around 20% less than allowed by the current law.
