Château Le Chay is in a constant struggle to create a balance between performance, wine quality, and environmental protection, making the vineyard the subject of attention. Each yard is monitored closely. The winemaker follows the principles of reasoned agriculture.​

The terroir is composed of silty clay and limestone, plateaus, and hillsides. It is located next to the reputable Chateau Les Laurets owned by Benjamin de Rothschild.
