Chateau Grillon is sited on the limestone plateau of Barsac. The close proximity of the Ciron river in early Autumn increases humidity and bathes the vines in morning mists, which later give way to sunshine. It is these very precise climatic conditions that give rise to Noble rot - a sugar concentrating fungus that causes the grapes to shrivel and concentrate their sugars and flavours. This fresh, zesty Sauvignon from France is made with organic grapes and contains no added sulphites.
