Today the Chambert vineyard covers 65Ha of the finest terroirs of the highest part of Cahors, 45 Ha of which are located directly around the château. The average height above sea level is 300m and only the best south-east facing slopes are planted with vines.
The vineyard area for making AOC Cahors is 93% Malbec and 4% Merlot. 3% of the estate is planted with Chardonnay.
The planting density of the vineyards is 4500 vines/Ha and 7400 vines/Ha for the vineyards planted since 2007.
After this period, the seabed rose, the water retreated, and the deposits were eventually transformed into compact limestone. During the last hundred million years, thanks to the alternation of ice ages and warm periods and the action of the air and rain, this layer has been broken up several meters deep, leaving a residual clay. These layers of clay and limestone deposits are the basis of part of the Quercy, often covered by other more recent deposits: ferrous clay, more recent sediments, silt, etc...
The soil consists of two very distinct soil characteristics that exist in different proportions for each of the 100 plots and provide infinite complexity for the final wine: White clay and limestone from oysters and fossilized marine life coated in decomposed clay ( Kimmeridgien period, 150 to 155 million years ago), identical to the soil found in Chablis. These soils give the Chambert wines their mineral precision, elegant acidity and great length.
Red Clay (Siderolithic) : a clay with very high concentrations of iron that was formed at a time when the land of Chambert resembled a tropical rain forest. (Eocene period, 34 to 56 million years ago). This type of soil gives the wine power and aromas of brooding black fruit.
Malbec, the historic grape of Cahors, is known locally as Côt Noir or Auxerrois, and it represents 93% of the vines planted at Chambert. This variety requires a great deal of care and provides very fruity and powerful wines. Merlot, an aromatic and supple varietal, represents 4% of the domain, and the remaining 3% of vines are Chardonnay.
Note: a wine produced in the AOC Cahors area must contain a mandatory minimum of 70% Malbec and only the varieties of Merlot to Tannat can complete this blend.
Gentle pruning is performed on our vines in winder, respecting the sap flow and extending the vines life span.
