Champ des Treilles is the family domaine of Corinne and Jean-Michel Comme. It was Jean-Michel’s grandparents, freshly arrived from their native Italy and eager to put down roots in their new home, who planted the first vines (1920s) in the far eastern corner of the Entre-Deux-Mers. M took over from his parents when they retired. Although deeply attached to the property, he struggled to carry on after losing his mother to cancer, convinced the cause was the chemicals used to treat the vineyards. Corinne helped him back on his feet and together they decided to experiment with biodynamic viticulture in the late 90s – a revelation for the couple. Showcasing the positive impact of biodynamics on the soils, vines, and employees at Champ des Treilles, Jean-Michel and Corinne convinced Château Pontet-Canet's owner Alfred Tesseron to apply similar principles to his 80ha Pauillac property. A revolution in this ultra-conservative region and a risky gamble that raised many eyebrows back in 2004. It was then that Champ des Treilles became the unofficial test lab for Pontet-Canet – it proved to be instrumental in cementing the Grand Cru Classé as one of Médoc’s finest.

Jean-Michel and Corinne made an impact on the region, quietly triggering a revolution with prestigious Châteaux (the likes of Latour, Margaux, Palmer, Climens to name a few) taking note and joining the ranks of Bordeaux's biodynamic estates.
