Le Marquis is Calon Ségur's second wine, and a meaningful step down in price from the grand vin without leaving the estate's vineyards or winemaking team behind. The blend leans more Merlot than the château wine (the grand vin is Cab-dominant in classic Saint-Estèphe fashion), which makes Le Marquis suppler and more approachable in its youth. 2020 is a strong, ripe Bordeaux vintage; this drinks well now with another decade of upside.
