Château Marsac Séguineau

The estate

Pierre Séguineau, a Bordeaux merchant, bought the land in 1770 and built the house. In 1804 Catherine Désirée Séguineau inherited it and married Jean-Baptiste Paul Joseph Deyries, and the estate became Séguineau-Deyries, a name the trade came to value. William Franck, whose Traité sur les vins du Médoc first appeared in 1824, lists Séguineau under Deyrie among the wines of Margaux that year, and Armand d’Armailhacq, a Pauillac grower, gives it 8 hectares and 16 tonneaux (the old Bordeaux measure of a crop, 900 liters, or 4 barrels) among the bourgeois supérieurs in his La culture des vignes of 1855. Years of neglect followed. Marie Blanche and Léon Marie de Robien bought it in 1886, renamed it Marsac-Séguineau, restored it and added vines from 1 of the best classed growths of Margaux; the vicomte de Couessan owned it in 1898. Mme Vast bought it early in 1903 and kept it at about 40 tonneaux, and in 1922 Charles Cocks and Édouard Féret, whose Bordeaux et ses vins was the reference book of the Bordeaux trade, counted its soft, fine, fragrant wine among the best of the commune.

Since 2001 Marsac Séguineau has been run jointly with its neighbor, Château La Tour de Mons, which Crédit Agricole Grands Crus sold to the Perrodo family in 2020; Marjolaine Maurice de Coninck, managing director and oenologist, leads the team, with Claude Gros as consultant. The 10 hectares lie in the heart of the Marsac plateau, on Garonne gravel and on clay and limestone. The vines are 32 years old on average and planted at 10,000 a hectare, pruned double Guyot, thinned, deleafed and green-harvested, and the estate has held Haute Valeur Environnementale (High Environmental Value, the French state’s environmental certification for farms) since the 2015 vintage. The grapes ferment slowly at low temperature in temperature-controlled steel vats, and the wine ages 12 months in French oak barrels, 25% new.
