It’s nearly 100 years since Louis Sèze acquired the Fronsac estate of Château Mayne-Vieil. Since then, Roger and now Bertrand Sèze have expanded the estate which today includes Château Buisson-Redon - a 15ha enclave of AOC Bordeaux. On this gently sloping vineyard of clay-loam soils, planted mainly with Merlot and Cabernet Franc, yields are naturally limited to boost the intensity of the wines.
Château Buisson-Redon uses permanent grass cover between the rows of vines to reduce the need for herbicide sprays and also to reduce the compaction of the soil as fewer passes by tractor are required. The increased competition for water and nutrients also reduces the vigour of the vines, thus reducing the need for green harvesting, reducing yields and increasing the concentration of the grapes. The château is on course for Agriculture Respectueuse de l’Environnement en Aquitaine (AREA) certification, equivalent to the HVE Level 2, from which it can eventually progress to full HVE 3 accreditation.
