Domaine du Pech is situated on the slopes of Sainte-Colombe-en-Bruilhois in the extreme south east of the appellation.Viticulture is “biodynamic”. No fertilizers have been used for twenty years. Since 2000 yields have been significantly reduced and since 2004 the drive towards biodynamic methods of cultivation has included the use of medicinal plants as well as minerals, thereby necessitating minimal treatments with copper or use of sulphur. Only natural yeasts and bacteria are used and the wines are bottled without filtration.
