Château Coutelin-Merville is a Cru Bourgeois de Saint-Estèphe, which was classified in 1932 when the classification was created. For over a century, it has been owned by the Estager family, originally from Corrèze since 1902.

In 1987, when Guy Estager died, his children took over the property :

- Bernard, chartered accountant who left everything to take over the estate and perpetuate the family tradition, not without obtaining the necessary diplomas.

- François, who brings his unconditional support and his constant collaboration.
