En 3 Temps

Le Château du Grand Bos is a family-run estate in Bordeaux’s Graves, purchased by André Vincent in 1988 and now led by his granddaughter Lou Rochet, who is both grower and winemaker. The vineyard is farmed organically and according to biodynamic principles, without herbicides or synthetic pesticides; grapes are hand-harvested, and only copper sulfate is used against mildew. The estate received organic certification in 2023 and holds the HVE 3 sustainable label. Its traditional approach includes winter protection and collaboration with a local beekeeper, reflecting a close connection to the vineyard and its surrounding ecosystem.
