Château d’Armailhac, an 1855 Classified Growth under the name Mouton
d’Armailhacq, covers 70ha in the northern part of Pauillac. The terroir is of light and very deep gravelly soil – the preference of Cabernet grapes, although all the traditional Médoc grape varieties are planted. The average age of the vineyard is 46 years, but nearly 20% of the total surface area dates back to  1890. The key harvesting decisions are made by an analytical and research laboratory which also monitors Château Mouton Rothschild.
