Côtes de Bordeaux

Before 2009, the four (now five) Côtes de Bordeaux sub-regions operated as separate appellations: Côtes de Castillon AOC, Premières Côtes de Blaye AOC, Premières Côtes de Bordeaux AOC (which became Cadillac Côtes de Bordeaux), and Côtes de Francs AOC. While each had its own identity, fragmentation made collective marketing and international recognition difficult. The 2009 INAO decree created the Côtes de Bordeaux umbrella designation as a way to unify these regions under a single commercial banner while preserving each sub-zone's distinctive identity. The umbrella requires red wines to meet specific blending and production standards across all sub-AOCs, while individual sub-AOCs retain their own specific rules and stylistic traditions. Sainte-Foy Côtes de Bordeaux joined the umbrella in 2020, becoming the fifth named sub-AOC. The umbrella has been broadly successful in raising international recognition of these satellite zones, particularly for Castillon Côtes de Bordeaux which has emerged as a serious quality producer.

• Côtes de Bordeaux umbrella established by INAO decree in 2009; consolidated four previously separate satellite AOCs
• Pre-2009 appellations: Côtes de Castillon, Premières Côtes de Blaye, Premières Côtes de Bordeaux (now Cadillac), Côtes de Francs
• Sainte-Foy Côtes de Bordeaux joined the umbrella in 2020, becoming the fifth named sub-AOC
• Umbrella designation has raised international recognition; Castillon has particularly emerged as a serious quality producer

Castillon Côtes de Bordeaux covers approximately 3,000 hectares east of Saint-Émilion on the Right Bank, sharing significant geological similarities with its prestigious neighbour. The terroir transitions from the Saint-Émilion limestone plateau in the western part of the appellation to clay-limestone hillsides further east. The wines are Merlot-dominant (typically 60 to 80 percent), with Cabernet Franc and Cabernet Sauvignon as supporting varieties. Several Saint-Émilion classified estates own vineyards in Castillon, recognising the terroir quality, and recent decades have seen significant investment from outside owners drawn by the value proposition: similar terroir to Saint-Émilion at a fraction of the cost. Notable Castillon estates include Château d'Aiguilhe (owned by Stephan Neipperg of Canon-La-Gaffelière), Château Le Rey, Château Veyry, and Château Vieux Château Champs de Mars.

• Castillon Côtes de Bordeaux: ~3,000 hectares east of Saint-Émilion; significant geological overlap with its prestigious neighbour
• Terroir: Saint-Émilion limestone plateau extending east; clay-limestone hillsides in the eastern part of the appellation
• Wines: Merlot-dominant (60-80% typical) with Cabernet Franc and Cabernet Sauvignon support
• Notable estates: Château d'Aiguilhe (Stephan Neipperg of Canon-La-Gaffelière), Château Veyry, Château Vieux Château Champs de Mars

Blaye Côtes de Bordeaux covers approximately 6,000 hectares across the Gironde estuary from the Médoc peninsula, making it the largest of the Côtes de Bordeaux sub-AOCs by area. The terroir includes limestone hillsides, clay-rich plains, and gravel-influenced parcels closer to the estuary. Production is overwhelmingly red wine (about 95 percent), with smaller dry white production from Sauvignon Blanc, Sémillon, and Colombard. The red wines are typically Merlot-led blends with Cabernet Sauvignon and Cabernet Franc support, producing more modest, everyday-drinking styles than the more prestigious Castillon Côtes de Bordeaux. The proximity to the Médoc across the Gironde gives Blaye a similar estuary-moderated climate, though without the deep gravel terroir that defines the famous Left Bank communes. The town of Blaye itself contains a UNESCO-listed Vauban-designed fortress (the Citadel of Blaye) overlooking the estuary.

• Blaye Côtes de Bordeaux: ~6,000 hectares across the Gironde from the Médoc; largest Côtes de Bordeaux sub-AOC by area
• Terroir: limestone hillsides, clay-rich plains, gravel-influenced parcels closer to the estuary
• Production: ~95% red wine (Merlot-led blends with Cabernet Sauvignon and Cabernet Franc); small dry white production
• The town of Blaye contains a UNESCO-listed Vauban-designed Citadel of Blaye overlooking the Gironde estuary

Cadillac Côtes de Bordeaux covers approximately 2,000 hectares of hillsides south of Entre-Deux-Mers, along the right bank of the Garonne. The appellation produces red wines and has historic associations with sweet white production (the separate Cadillac AOC covers sweet whites). Francs Côtes de Bordeaux, the smallest of the original four sub-AOCs at approximately 500 hectares, sits east of Saint-Émilion adjoining the Castillon Côtes de Bordeaux boundary. Despite its small size, Francs has attracted significant outside investment, particularly from Right Bank Saint-Émilion families and négociants seeking to develop micro-cuvée projects. Sainte-Foy Côtes de Bordeaux, which joined the umbrella in 2020, covers approximately 350 hectares in the easternmost extreme of Bordeaux's vineyard area, bordering Bergerac. These three smaller sub-AOCs collectively cover roughly 3,000 hectares and produce mostly accessible Merlot-led red wines for everyday drinking at value pricing.

• Cadillac Côtes de Bordeaux: ~2,000 hectares south of Entre-Deux-Mers; red wines (separate Cadillac AOC covers sweet whites)
• Francs Côtes de Bordeaux: ~500 hectares east of Saint-Émilion; smallest of the original four; significant Saint-Émilion family investment
• Sainte-Foy Côtes de Bordeaux: ~350 hectares in easternmost Bordeaux bordering Bergerac; joined umbrella in 2020
• Combined three smaller sub-AOCs: ~3,000 hectares producing mostly accessible Merlot-led reds for everyday drinking at value pricing

Côtes de Bordeaux wines occupy a distinctive value position in the Bordeaux market. Typical pricing runs $15 to $45 per bottle for serious red wines, reflecting terroir quality and producer skill without the prestige tier markup of named communal AOCs (Pauillac, Margaux, Saint-Émilion, Pomerol). For sophisticated buyers, these wines offer access to Right Bank Merlot-Cabernet Franc style (Castillon, Francs) or modified Left Bank style (Blaye) at a fraction of comparable named-AOC pricing. The umbrella designation has helped raise international recognition of these zones in the United States, United Kingdom, and Asian markets, where buyers often value the terroir authenticity and producer quality over the historical prestige hierarchy. Top Castillon wines are now reviewed by major critics alongside named Right Bank classifications, with several producers exporting at premium tier pricing rivalling Grand Cru Classé Saint-Émilion.

• Typical Côtes de Bordeaux pricing: $15-45 per bottle for serious reds; value proposition based on terroir quality without prestige markup
• Castillon Côtes de Bordeaux offers Right Bank Merlot-Cab Franc style at a fraction of Saint-Émilion pricing
• Top Castillon wines (Château d'Aiguilhe, Veyry, others) now reviewed alongside named Right Bank classifications by major critics
• Umbrella designation raised international recognition particularly in US, UK, and Asian markets where terroir authenticity is valued
