Tucked between châteaux Cos d'Estournel and Montrose, the vineyard covers 61 hectares (150 acres) and is planted with 50% Cabernet Sauvignon, 40% Merlot, and 10% Cabernet Franc. Overlooking the Gironde estuary, it is mainly located on the gravel ridge of Marbuzet and the plateau of Long Treytin. The high proportion of merlot, rather unusual in traditional blendings, as well as a long maturing in new oak barrels, greatly contribute to the mellowness of the wine. Often described as exotic or opulent, Haut-Marbuzet wines develop a suppleness and an individual expressive character that are unusual in the normally austere style of Saint-Estèphe.
A second wine is produced from the vines under 12 years old, under the label Château MacCarthy which bears the name of the Irish Jacobite family who created the vineyard.
No vintage in the post-World War era has a reputation as great as 1945. Its legendary status is well deserved based solely on the quality of the wines, but the fact that it is the “victory” vintage following World War II only adds to its luster. 1945 was a remarkably good vintage for virtually every wine region in the world, but it was especially great for Claret. Interestingly, the harvest in Bordeaux got underway on September 13th, the same date as the 1982 harvest began exactly 37 years later.
The top reds of Bordeaux started out with massive levels of tannin and took decades to develop. Due to the high concentration of fruit and tannin levels, many of the wines still show beautifully today.
