Médoc AOC
Médoc AOC covers red-wine vineyards on Bordeaux's Left Bank peninsula between the Atlantic Ocean and Gironde estuary. Gravel, sand, clay, maritime moderation, and drainage shape Cabernet Sauvignon- and Merlot-based blends, while several recognized communal appellations occupy more specific sites within the broader Médoc territory.
Overview
Médoc AOC lies on the northern portion of the Médoc peninsula, with vineyards positioned between the Atlantic Ocean and the Gironde estuary. The broader Médoc territory also contains Haut-Médoc and communal appellations such as Margaux, Pauillac, Saint-Julien, and Saint-Estèphe, which are separate protected origins rather than subdivisions of every Médoc AOC wine.
Oceanic and estuarine influence moderate temperature, while forests help shelter vineyards from direct Atlantic weather. Gravel rises, sandy sectors, clay, and mixed alluvial deposits create differences in drainage and water availability. Cabernet Sauvignon performs strongly on warm, free-draining gravel, while Merlot is important where clay retains more moisture.
Only red wines carry the Médoc AOC. Blends typically combine Cabernet Sauvignon and Merlot with Cabernet Franc, Petit Verdot, and smaller permitted varieties, producing wines that range from approachable and fruit-driven to structured and ageworthy.
The graph should distinguish Médoc AOC from the entire Médoc peninsula and from its neighboring communal appellations. Links to estates, vineyards, grapes, classifications, and wines provide the specificity that the broad geographic name alone cannot. This distinction also prevents classification from being mistaken for appellation. Classified growth, Cru Bourgeois, Cru Artisan, and unclassified estates can occupy different Médoc AOCs, while the protected origin describes where and how the wine is produced. Separate relationships preserve both systems without turning one into the other.
Geography & Climate
The appellation occupies the northern Médoc peninsula between ocean, estuary, marshes, forest, and low vineyard rises. Its terrain is generally modest in elevation but includes low ridges, flat terraces, drainage channels, and gently rolling inland sectors.
Soils
Soils include gravelly terraces, sand, clay, limestone-influenced material, and mixed alluvial deposits. Free-draining gravel favors deep rooting and heat storage, while clay-rich sectors retain more water and often support a larger role for Merlot.
Wine Styles
Médoc AOC produces dry red blends centered on Cabernet Sauvignon and Merlot. Styles generally combine dark fruit, savory structure, and moderate oak influence, with weight and aging capacity varying by site, vintage, and estate.
