The farm has, from its very beginning, chosen to cultivate the lands according with norms indicated by the biological agriculture. The vineyards are surrounded by woods that create a great, natural protective barrier. Manure and other organic materials of biological origin are used as fertilizers. To help fight diseases that might affect the vines, traditional products, such as sulphur and, in rigorously controlled quantities, copper, are used. Many operations including the harvest are carried out manually to permit the best quality of the grapes. Weed killers are never used.
