Château Cos d'Estournel

The estate has changed hands several times during its history, starting in 1852 when it was purchased by the English banker Charles Cecil Martyns.

Through his marriage to Marie-Thérèse Hostein, Louis-Victor Charmolue, who also owned Château Montrose, gained control of Cos d'Estournel in 1894.

In June 2008 it was announced that Michel Reybier, current owner of Cos d'Estournel, purchased Napa winery Chateau Montelena for an undisclosed sum.

[2] By November 2008, however, this agreement was cancelled,[3] the termination of the transaction by Chateau Montelena stated to be due to that Reybier Investments had been "unable to meet its obligations".

[4] From a 100 hectare estate, the vineyard area extends 70 hectares (170 acres), divided into 30 parcels, primarily composed of the grape varieties of 60% Cabernet Sauvignon and 40% Merlot, with minor cultivation of Cabernet Franc and Petit verdot that appears to participate little in the modern production.
