The winery is located on the Left Bank of the Bordeaux wine regions, in the commune of Saint-Seurin-de-Cadourne north of Saint-Estèphe, France.
Situated on what was in 1633 the residence of a Basque nobleman named Sièvre Sociando, the first documentation of the estate mentions its nobles terres.
[1][2] After its acquisition around 1850 by Madame Mallet, it was recorded in the 1883 edition of Cocks & Féret along with Château Verdignan as the leading cru of Saint-Seurin.
[1] Sociando-Mallet was a forgotten and derelict property of vastly reduced land by the time it was bought by Jean Gautreau, a négociant from Lesparre, in 1969.
[1][2] The estate has since seen considerable expansion and modernisation, and enjoys high prices and a good reputation in today's wine market.
