In the 19th century, on 14 January 1859 to be precise, the château became the property of the Miailhe family. Their ancestor, Leo Barbier, bought the estate for 100,000 francs from the Count and Countess of Toulouse-Lautrec, the grandparents of the famous painter of Parisnightlife Henri de Toulouse-Lautrec. Thus, it was 4 years after the world-renown 1855 Classification that the estate passed into the ownership of a family of wine professionals.
The vineyards of the estate, situated on the plateau of Labarde in the Margaux appellation, are entirely surrounded by classed growth of 1855. Several authorities and critics have opined that had the wines of Siran been presented for classification in the 1855 exhibit, Siran would have made into the precious classification.
Subsequently, since the mid 19th century, the family’s descendents followed one another in full respect of the family tradition. In 2007, the family’s fifth generation, represented by Edouard Miailhe, become involved in the management of the estate, following its parents Brigitte and William-Alain Miailhe.
Château Siran is one of the rare Bordeaux châteaux to belong to the same family for nearly 150 years.
