The Dujac estate has been certified in organic farming since 2011 and has been managed according to biodynamic principles since 2003. In practice, this translates into manual ploughing of the soils, the absence of herbicides, and the occasional use of organic compost to nourish microbial life. The estate considers that wine is made first and foremost in the vineyard: the winemaker's intervention in the cellar must remain as discreet as possible to let the terroir speak.
