Merlot is a dark blue–colored wine grape variety that is used as both a blending grape and for varietal wines. The name Merlot is thought to be a diminutive of merle, the French name for the blackbird, probably a reference to the color of the grape. Its softness and "fleshiness," combined with its earlier ripening, make Merlot a popular grape for blending with the sterner, later-ripening Cabernet Sauvignon, which tends to be higher in tannin.

Médoc is an AOC for wine in the Bordeaux wine region of southwestern France, on the Left Bank of the Gironde estuary that covers the northern section of the viticultural strip along the Médoc peninsula. The zone is sometimes called Bas-Médoc, though this term is not permitted on any label. With few exceptions there is produced only red wine, and no white wine has the right to be called Médoc.
