Bordeaux
The largest fine wine region on earth. 57 appellations. Two banks. One estuary. Six centuries of documented winemaking.
Bordeaux wine is wine produced within the Gironde department and parts of adjacent departments in southwestern France, under the Appellation d'Origine Protégée (AOP) framework administered by the Institut National de l'Origine et de la Qualité (INAO). The Bordeaux AOP (general appellation) was established by decree on 16 November 1936. There are currently 57 Bordeaux AOPs, covering red wine, white wine (dry and sweet), rosé, and sparkling wine (Crémant de Bordeaux). The production zone covers approximately 111,000 hectares of planted vines. Permitted red grape varieties include Cabernet Sauvignon, Merlot, Cabernet Franc, Petit Verdot, Malbec, and Carménère. Permitted white grape varieties include Sauvignon Blanc, Sémillon, Muscadelle, Sauvignon Gris, Ugni Blanc, Colombard, Merlot Blanc, and others per appellation specification. The CIVB is the professional body overseeing the region's wine trade.
What Bordeaux is — and why it matters globally
Bordeaux is the city and the wine region. The city of Bordeaux sits on the Garonne River in the Gironde department of southwestern France. The wine region extends across both sides of the Gironde Estuary — the place where the Garonne and Dordogne rivers meet and flow to the Atlantic Ocean. This geography is fundamental: the river system moderates temperature, the Atlantic proximity creates maritime weather, and the varied soils of the Left Bank (Médoc peninsula, Graves) and Right Bank (St-Émilion, Pomerol) produce distinctly different wines from similar grape varieties.
Bordeaux is the world's largest fine wine region by any measure — approximately 700 million bottles produced annually, around 111,000 hectares under vine, and a wine trade worth approximately €4 billion in export value per year (CIVB data). Its influence on global wine culture is unmatched: the "Bordeaux Blend" — Cabernet Sauvignon, Merlot, and Cabernet Franc as core varieties — is the dominant red wine blend across California, Australia, South Africa, Argentina, Chile, and virtually every other major wine-producing country.
Left Bank vs Right Bank — why the Gironde creates two worlds
The Gironde Estuary divides Bordeaux into two fundamentally different wine-producing environments, each dominated by a different primary grape variety.
The Left Bank (the Médoc peninsula, extending north of Bordeaux city, and the Graves and Pessac-Léognan region to the south) is dominated by Cabernet Sauvignon. The soils are primarily deep gravel deposits — well-drained, warm-retaining, and relatively poor in organic matter, forcing vines to root deeply. Cabernet Sauvignon ripens well in this environment and is the dominant variety. The major Left Bank appellations include the Médoc communal appellations: Pauillac, St-Julien, Margaux, St-Estèphe, and others.
The Right Bank (St-Émilion and Pomerol plateau, east of the Dordogne) has cooler, clay-rich soils that suit Merlot. Merlot ripens earlier and produces rounder, more approachable wines in these conditions than Cabernet Sauvignon would. Pomerol — the smallest and most expensive subregion — produces Merlot-dominant wines, including Pétrus, one of the most valuable wines on earth.
The 1855 Classification — what it is and why it still matters
The 1855 Classification was commissioned by Napoleon III for the 1855 Paris Universal Exhibition — he wanted to present the world's greatest wines. The Bordeaux Chamber of Commerce ranked 61 red wine châteaux from the Médoc (and Château Haut-Brion from Graves) into five tiers — Premier Cru (First Growth) through Cinquième Cru (Fifth Growth) — based on the price their wines commanded at the time. This ranking has been amended only once: in 1973, when Mouton Rothschild was elevated from Second to First Growth.
The 1855 Classification is not an INAO regulatory requirement — it is a historic commercial ranking maintained by custom and commercial importance. It is not the same as the Bordeaux AOP appellation system. A wine can be a Bordeaux AOP without being in the 1855 Classification, and the Classification only covers specific Médoc and Graves châteaux. St-Émilion has its own separate classification (the St-Émilion Grand Cru Classé system, most recently revised in 2022), and Pomerol has no official classification at all.
The 57 Bordeaux appellations — by category
All Bordeaux AOPs operate within the general EU PDO framework for wine (EU Regulation 1308/2013) and the INAO appellation specification system. Each AOP has its own approved grape varieties, yield limits, minimum natural alcohol levels, and production methods specified in a Cahier des Charges (technical specification document).
These are the major appellations. The full 57 Bordeaux AOPs include additional satellite appellations of St-Émilion (Lussac-St-Émilion, Montagne-St-Émilion, Puisseguin-St-Émilion, St-Georges-St-Émilion), right bank Côtes designations (Blaye Côtes de Bordeaux, Castillon Côtes de Bordeaux, Francs Côtes de Bordeaux, Cadillac Côtes de Bordeaux), Entre-Deux-Mers (dry white between the rivers), Crémant de Bordeaux (sparkling), and others. All full specifications available from INAO (inao.gouv.fr).

The Bordeaux Blend — chemistry and agronomic rationale
The Bordeaux Blend is not an aesthetic preference — it is an agronomic risk management strategy developed over centuries of variable Atlantic weather. Cabernet Sauvignon ripens late; in cool years, it may not reach full phenolic ripeness. Merlot ripens two weeks earlier and can be harvested before autumn rain threatens. Cabernet Franc has different disease resistance. Petit Verdot contributes colour depth. By blending varieties that ripen at different times and have different sensitivities to weather conditions, Bordeaux producers reduce the risk that a single poor-weather event destroys the entire harvest.
The chemistry of the blend reflects the contributions of each variety: Cabernet Sauvignon provides high tannin (primarily from procyanidins), high anthocyanin colour, and pyrazine-derived green pepper notes that diminish with age. Merlot contributes lower tannin, higher sugar concentration (higher natural alcohol potential), and plum and chocolate-derived ester character. Cabernet Franc provides florality (violet, raspberry) from geraniol and nerol terpenes. Petit Verdot provides very dark colour and spice notes. These contributions are documented in flavour chemistry literature (Ribéreau-Gayon et al., Handbook of Enology).
The St-Émilion 2022 classification controversy
The St-Émilion Grand Cru Classé classification, revised every ten years, was most recently updated in September 2022. Two châteaux — Figeac and Pavie — were promoted to Premier Grand Cru Classé A status (the highest tier), joining Ausone and Cheval Blanc. Several previously classified châteaux were demoted. Multiple demoted châteaux filed legal challenges against INAO, and the 2022 classification was temporarily suspended by a Paris administrative court in November 2022 before being restored. The legal dispute centred on whether the classification process had been conducted with appropriate independence from conflicts of interest. As of May 2026, the 2022 classification is the operative version. This codex documents the status as of verified date; consult INAO directly for current legal standing.
