Hervé Duboscq became the owner of a plot of seven hectares called Château HAUT-MARBUZET in 1952. He resurrected the vineyard and gave rise to a wine of its own style, which immediately charmed many experts. In 1962, his son Henri joined him in order to help him reach the only goal, which is precious to the Duboscqs, the “glory of Haut-Marbuzet”. After buying the neighbouring vineyards, as well as pockets, which were originally the result of the Mac-Carthy’s parcelling out, the vineyard attained an area of 66 hectares in 2005.
At the same time, the Duboscqs bought the chateaux Chambert-Marbuzet, Tour de Marbuzet and Mac-Carthy. All three are crus Bourgeois of Saint-Estephe.
The greater part of the vineyard of Haut-Marbuzet is made up of a gravelly topsoil and a clay-limestone subsoil that contains iron. The Graves wine owes its name to its soil, which contains gravel of various size. The gravel stores the sun’s heat during the day and at nightfall, it emits the heat back to the grapevines. The gravel is deposit from the Gironde river. It forms a series of slightly sloping terraces. The high density of plantation is immediately visible in the vineyards. On average, there are 9,000 vines per hectare. High-density planting ensures an equal yield with lesser grapes per vine, but better quality grapes. At Haut-Marbuzet, this high density also increases the competition between the grapevines and encourages a deep root system : « the typicality of the terroir lies at a depth of four meters ».
The deep rooting system of the grapevines as well as the banishment of chemical herbicides best reflect the characteristics of this terroir. The vineyard of Château Haut-Marbuzet is made up of 50% Cabernet Sauvignon, 40% Merlot and 10% Cabernet Franc and Petit Verdot. The strong presence of Merlot gives the wine a smooth and mellow taste. It complements the austere notes of Cabernet Sauvignon with its opulence, charm and seduction.
