Since the death of Baron Philippe in 1988, the estate has come under the control of his daughter Baroness Philippine de Rothschild, with the assistance of her two sons. The wine holdings of the family also include Château Clerc Milon, Château d’Armailhac in the Bordeaux region and Domaine de Baron’Arques in the Aude. The overseas interests include Opus One, produced in Oakville AVA, Napa Valley, in partnership with Robert Mondavi Winery. In Chile, Almaviva is produced in Partnership with Concha y Toro.
In 1973 Château Mouton Rothschild was elevated to the status of first growth, one of only two changes to have occurred in the 1855 classification (the other being the addition of Château Cantermerle as a 5ème cru in 1856).
The wine is made from old vines (average age 44 years) and aged for 19-22 months in new oak barrels.
Average annual production is 20,000 cases.
Grape: 83% Cabernet Sauvignon, 13% Merlot, 3% Cabernet Franc
The second wine of Mouton Rothschild is Le Petit Mouton de Rothschild; the estate also produces a white wine named Aile d’Argent.
