The Grand Vin of Calon Segur is the mirror image of its terroir, revealing both lovely softness and amazing intensity. The vines, 8,000 per hectare, are planted on deep gravel that lies atop clay. 54% of the vines are Cabernet Sauvignon, 38% Merlot, 7% Cabernet Franc and 2% Petit Verdot.

The manual harvest is followed by both shake-table and hand-sorting. Fermentation is in temperature-controlled conical stainless-steel tanks with maceration for 18 to 21 days. The wine ages 18 to 20 months in 30% new French oak barrels and are fined with egg whites.
