(Decanter) - Laithwaites Wine, the independent wine merchant begun in the late 60s by Tony Laithwaite, has purchased a third estate in Bordeaux. Chateau du Bois, a 25-hectare AOC Castillon Cotes de Bordeaux estate, is in the Castillon village of Saint Colombe, where Tony Laithwaite (pictured) bought his first vineyard, Chateau La Clariere, in 1980. Combined with his existing properties of La Clariere and Chateau Verniotte, the family now has a total vineyard area of 30 hectares.
