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.
The characteristics of Haut-Marbuzet are mostly defined by its wine-producing methods.
The grapes are harvested once they are very ripe, then destalked. The maceration time is very long. Owner Henri Duboscq remains committed to using traditional materials, like concrete vats. They preserve the natural yeasts of past wines. Henri Duboscq says that he likes the idea that each year, the new yeasts revive the old ones, and the old influence the new.
The Duboscq were among the first to harvest overripe grapes. The wine is then matured in new oak barrels. Here, too, Haut-Marbuzet was among the first to use this production technique. All of these practices complete the characteristics of the terroir. They influence the color of the wine, its structure, its body, and finish.
Henri Duboscq often speaks of his love of unctuous wines, feminine wines that have fine, woody scents, with soft and ripe tannins. From this point of view, the wine of Haut-Marbuzet clearly stands apart from the classical wine of Saint Estèphe which is more virile, austere and astringent.
Tasting notes
Haut-Marbuzet shows a dark and intense color and a delicous bouquet of red and black fruit aromas, violet, pepper and coconut nuances. On the palate, the wine is rich and unctuous, with fine and peppery tannins that support the solid and fresh texture.
Review:
"Black and blue fruit, walnuts, gravy, vanilla, praline and cigar box on the nose. Full-bodied with fine tannins. Balanced, layered and polished with a fleshy texture. Harmonious, with elegance and intensity. Beautiful finish. Wow. Drink from 2025."

Beginning in 1993 and following in the tradition of great Bordeaux estates, Opus One created a fine second wine called Overture. Every acre of the estate vineyard is meticulously farmed with the attention to detail and singular focus required to produce Opus One. This scrutiny carries through the blending process and certain lots will not be included in the final Opus One blend. Yet, when these lots are afforded additional time in barrel along with the added flexibility of blending across multiple vintages, the final wine achieves a remarkable elegance and complexity.
Overture displays a vibrant garnet color with expressive aromas of fresh red fruit. Notes of bright cherry and red currant are underpinned by more earthy tones of ground cocoa, cedar and vanilla. Extended barrel aging gives the wine an elegant texture accentuated by round tannins and a soft mouthfeel.
Review:
The first time specific blocks have been used for this wine. Dark forest berry notes on the nose with perfumed elements and notes of milk chocolate. Supple and agile, generous with textured, slightly grainy tannins that are so pleasant - expansive and round in the mouth. It's well built and very approachable with blackcurrant and black cherry flavours on the palate. Concentrated, deep and layered but still with elegance. Extremely characterful. A blend of the 2018 and 2019 vintages with 18 months ageing in French oak barrels. 1% Petit Verdot completes the blend.

Morambro Creek Cabernet is 100 percent Cabernet
Deep purple in color. A rich elegant nose of cassis with overtones of vanilla and coffee. Lush, ripe palate dominated by black fruits, cherry and chocolate. Full bodied with savory, integrated fruit tannins and persistent finish.
Winemaking at Morambro Creek is very traditional and labour intensive. Oak maturation takes place using 35% new French barrels. This blend was put together using select barrels from our family estate that best demonstrate the intensity of our fruit balanced by integrated oak.
