The Chateau de Cantermerle vineyard covers 91 hectares of vines in the Haut-Medoc. The soils are silica-gravel, resulting from a thousand-year-old erosion of the Pyrenees by the River Garonne and forming one of the fundamental elements of this quality vineyard. The soils are poor in nutrients, so the vines 'struggle', resulting in a high flavour concentration of grapes. In addition, the small pebbles in the soil provide a filter and contribute to the grape's maturity by reflecting the sun's rays during the day and retaining the heat during the cooler nights. The vines have an average age of 30 years and are planted at a density of 8,300 vines per hectare, yielding between 50 to 55 hectolitres per hectare. The vines are pruned to the Medoc Double Guyot method and are grafted onto the phylloxera-resistant 3309-10114 Riparia Gloire rootstock.
