Thierry Allemand does not claim any official organic certification, but his practices come very close to it. In the vineyard, he uses neither herbicides nor synthetic pesticides, limiting his interventions to sulphur and copper. As mechanisation is impossible on the steep terraces of Cornas, all vineyard operations are carried out by hand. In the cellar, the philosophy is in the same spirit: macerations and punch-downs are slow and gentle, fermentations take place without added inputs, and ageing lasts approximately 24 months in multi-vintage barrels, sometimes followed by three additional months in large oak casks. Sulphur, when used, is dosed to a minimum at the time of bottling.
