Fifty-five hectares (136 acres) at the time of the 1855 classification, fifty-five hectares today: the estate is a rare example of consistency of terroir over the centuries.
The vineyard is made up of one single block adjacent to the village of Saint-Estèphe. Unique in the Médoc, it is completely surrounded by a stone wall. Inside, closest to the château, this “enclos” groups together the most famous plots of Calon.
There are very few geological models that can be compared with the terroir of Calon Ségur. The vines delve down into a deep gravel layer that was deposited there by the river. This layer covers another which is predominantly clay. This combination of clay and gravel soils is one of the main reasons for the power and finesse displayed in the wines of Calon Ségur.
Cabernet Sauvignon is the backbone of Calon Ségur. This grape variety makes up over three-quarters of the blend, and in great years its proportion can be as high as 90%.
No great wines can ever be made without constant and meticulous care of the vines. The soils are ploughed in the time-honoured tradition. From spring to autumn, vine canopy management tasks are done by large numbers of vineyard personnel. The crop is picked by hand at perfect ripeness.
