Château Montrose is one of the leading wine properties of St.Estéphe, and produces some of the longest-lived wines in the Médoc. Montrose had been owned by Jean-Louis Charmolue from 1962 until 2006, when it was sold to Martin and Olivier Bouygues, owner of the eponymously named construction firm Bouygues, is located in the east of the appellation, just north of the hamlet of Marbuzet, on a gravel knoll only 800 metres from the Gironde estuary. The proximity of the estuary ensures a microclimate that protects against frost, and the vines, which lie on deep clay-gravel soils, benefit from a south-easterly aspect. Montrose's wine is typically a blend of 65% Cabernet Sauvignon, 25% Merlot and 10% Cabernet Franc and is matured in oak barriques (30% new) for 18 months. Montrose wines are traditionally deeply coloured, austere and powerful when young, yet possess superb ageing potential, and when mature are quintessential St.Estèphe clarets. Montrose is classified as a 2ème Cru Classé.
