Médoc
meh-DOK
The Left Bank peninsula north of Bordeaux, set between the Atlantic Ocean and the Gironde estuary, whose eight appellations include Pauillac, Saint-Julien, Margaux and Saint-Estèphe.
The Médoc is the gravelly peninsula north of Bordeaux city on the Left Bank: INAO's cahier des charges for the Médoc AOC says its wine-growing part stretches for nearly 80 kilometres from north to south and barely more than ten kilometres from east to west, across 50 communes. Bordeaux.com, the site of the Bordeaux wine interprofession, counts eight appellations here: Médoc, Haut-Médoc and six communal appellations (Saint-Estèphe, Pauillac, Saint-Julien, Listrac-Médoc, Moulis and Margaux). INAO places the Médoc AOC vineyard on the northern half of the Médoc and the Haut-Médoc AOC on the southern half. Its soils mix Quaternary gravel carried by the rivers with Tertiary clay-limestone, and INAO credits the Atlantic to the west and the Gironde estuary to the east with a regulating thermal effect. Cabernet Sauvignon is the majority variety in Médoc and Haut-Médoc reds, according to INAO. Bordeaux.com counts 60 Médoc estates among the red wines of the 1855 Classification, with Château Haut-Brion in the Graves as the one exception; the Crus Bourgeois du Médoc classification covers many of the other estates.
Historical Development
INAO's cahier des charges for the Médoc AOC traces the region's name to the Médulli, the people who lived there, and places the first vine growing in the Gallo-Roman era. Until the 17th century the Médoc was very marshy: INAO's product page records that Henri IV's edict of 8 April 1599 decreed the draining of the coastal marshes, and that many Flemish workers came to drain the estuary lowlands at the start of the 17th century. Bordeaux.com credits Dutch engineers with drying the wetlands in the 17th century. According to INAO, the draining of the marshes, city capital and the first classifications of estates in the 17th century set the stage for the vineyard's growth, and after the Great Winter of 1709, during the vogue for 'New French Clarets', new red plantings used only small-berried varieties: Carmenère, Cabernet Franc, Cabernet Sauvignon, Petit Verdot, Cot and Merlot. Bordeaux.com's Haut-Médoc page notes that the Bordeaux nobility built estates there from the 16th century onwards, the predecessors of today's châteaux. INAO says Cabernet Sauvignon became the principal variety at the start of the 20th century. The Médoc AOC was recognised by decree on 14 November 1936, and bordeaux.com says winegrowing became predominant in the Médoc from the 1960s onwards.

Geography, Climate, and Terroir
INAO places the Médoc AOC's geographical area in the Gironde department on the left bank of the Garonne and then of the Gironde, north of Bordeaux, and says its wine-growing part stretches for nearly 80 kilometres from north to south. The vineyard landscape is gently contoured, between 3 and 50 metres of altitude, bounded by forest to the west and the Gironde estuary to the east. INAO describes Tertiary marine clay-limestone layers overlain, during the alternating glacial periods of the Quaternary, by river deposits of moraines, gravel, sand and silt; after erosion inverted the relief, these became outlier mounds of Garonne or glacial gravel ranging from small pebbles to large stones. The other defining factor, according to INAO, is topographic: the land is cut into gravel rises called 'cos', shaped by erosion and by the Garonne and its tributaries (the 'esteys' and 'jalles') digging their beds in the glacial periods. On climate, INAO notes that the river frontage moderates seasonal swings and receives measured rainfall for an Atlantic climate, thanks to the regulating thermal effect of the Atlantic Ocean to the west and the Gironde estuary to the east, and that the oceanic climate produces a marked vintage effect.

INAO places the Haut-Médoc AOC on the southern half of the Médoc vineyard, and bordeaux.com notes that the Haut-Médoc appellation is itself part of the Médoc delimited area and encompasses six communal appellations: Saint-Estèphe, Pauillac, Saint-Julien, Listrac-Médoc, Moulis and Margaux. Bordeaux.com explains that the 'Haut' refers to its position on the upper part of the estuary, towards Bordeaux, and counts 240 winegrowers across 25 communes in the Haut-Médoc as of 2026. INAO says the Haut-Médoc AOC itself has five estates in the 1855 Classification. Bordeaux.com gives Pauillac 18 Grands Crus Classés in the 1855 classification, including 3 Premiers Crus, on soils mainly of gravel, sand and clay. Saint-Julien has 11 Great Growths in the 1855 classification across 910 hectares, with a gravel layer 5 kilometres long and 3.5 kilometres wide, per bordeaux.com as of 2026. Margaux has the highest number of Great Growths in the 1855 classification, 21 of the 61 classified, across 1,500 hectares in four communes (Arsac, Labarde, Margaux-Cantenac and Soussans), per bordeaux.com as of 2026. Saint-Estèphe has 5 Great Growths in the 1855 classification across 1,200 hectares, on gravel over a marine limestone subsoil, per bordeaux.com as of 2026. Listrac-Médoc (570 hectares) and Moulis (600 hectares) complete the six; bordeaux.com, as of 2026, calls Listrac the highest point of the Médoc at 43 metres and describes Merlot as the main grape in both.

Médoc AOC: the Northern Peninsula
The Médoc AOC's geographical area covers 50 communes across the wine-growing part of the peninsula, but INAO's product page places its vineyard on the northern half of the Médoc, and bordeaux.com says its red wines are mainly produced in the north of the appellation. As of 2026, bordeaux.com counts 41 communes, including 16 where Médoc AOC red wines predominate, and 285 winegrowers, who usually work in family-owned estates. Bordeaux.com describes vines sheltered from the wind by the nearby forest and a mild climate shaped by the Gironde estuary and the Atlantic Ocean. The appellation has produced dry white wines since 2025, according to bordeaux.com, and INAO's cahier des charges reserves the Médoc AOC for still white and red wines; the whites come from Sauvignon Blanc, Sauvignon Gris, Sémillon and Muscadelle. INAO records white wine production in the Médoc since at least the early 18th century, over 16,000 hectolitres in 1929, 1,800 hectolitres in 1969 and over 5,000 hectolitres in 2023. Bordeaux.com adds that the Médoc became France's 54th Regional Natural Park in 2019.
- INAO: the Médoc AOC vineyard lies on the northern half of the Médoc; the Haut-Médoc AOC on the southern half
- Bordeaux.com (as of 2026): 41 communes, 16 of them where Médoc AOC reds predominate, and 285 winegrowers

INAO's cahier des charges lists the red varieties of the Médoc AOC as Cabernet Franc, Cabernet Sauvignon, Carmenère, Merlot, Cot (Malbec) and Petit Verdot, and allows the adaptation varieties Arinarnoa, Castets, Marselan and Touriga Nacional at up to 5% of an estate's plantings. According to INAO, Cabernet Sauvignon is the variety of choice on gravel soils, Merlot is sought for its fruit, Cabernet Franc goes on limestone-dominant soils and Petit Verdot on warm, free-draining land. The red wines are tannic and deeply coloured, INAO says, built mainly on Cabernet Sauvignon, which gives spicy notes, with Merlot adding roundness, suppleness and red fruit aromas, and Cabernet Franc or Petit Verdot reinforcing structure and complexity, Petit Verdot also adding freshness. INAO credits the reds with excellent ageing aptitude. Proportions vary by commune: bordeaux.com gives Saint-Estèphe 50% Cabernet Sauvignon, 40% Merlot, 7% Cabernet Franc and 3% Petit Verdot as of 2026, while Merlot is the main grape in Listrac-Médoc and Moulis. JancisRobinson.com describes the four famous communes, in theory, as silky and fragrant (Margaux), perfectly balanced (Saint-Julien), minerals and cassis (Pauillac) and slightly austere (Saint-Estèphe). The Crus Bourgeois du Médoc classification, first drawn up in 1932, listed 249 châteaux in 2020 (14 Exceptionnel, 56 Supérieur, 179 Cru Bourgeois, per Decanter) and 170 in 2025 (14 Exceptionnel, 36 Supérieur, 120 Cru Bourgeois, per Decanter), across seven Médoc appellations per bordeaux.com.

Get the DeckMédoc red wines are anchored by Cabernet Sauvignon's classic Left Bank profile: deep ruby colour, blackcurrant, cassis, and dark cherry fruit, with the firm tannic structure and mineral graphite character that defines age-worthy claret. Pauillac wines lead with the most structured, dense profile and the longest aging trajectories. Saint-Julien shows comparable structure with greater elegance and slightly earlier accessibility. Margaux wines emphasise floral perfume, violet aromatics, and silken tannin integration. Saint-Estèphe brings fuller, more rustic character with slower evolution. With age, Médoc wines develop tertiary complexity: cedar, tobacco, leather, dried herbs, forest floor, and integrated oak. Médoc AOC and lesser Haut-Médoc wines show similar profiles at less concentrated scale. French oak aging (typically 12 to 24 months in 225-litre barriques, with 50 to 100 percent new oak at classified estates) adds vanilla, toast, and spice complexity.
