Bordeaux Blanc AOC

Bordeaux's wine exports to England grew dramatically after the 1152 marriage of Henry Plantagenet and Eleanor of Aquitaine, whose lands included the Bordeaux region. While medieval exports were dominated by red clairet, white wine was always part of the regional mix. The modern era of Bordeaux Blanc was shaped in the 1950s and onwards when producers like André Lurton at Château Bonnet pioneered cold fermentation and skin maceration, transforming the regional image from oxidized, flabby wines into the clean, aromatic style recognizable today. The Entre-Deux-Mers AOC was formally established in 1937 and restricted to dry white wine by 1957.

• 1152: marriage of Henry Plantagenet and Eleanor of Aquitaine opened Bordeaux to English export markets
• 1937: Entre-Deux-Mers AOC created; restricted to dry white wine only from 1957
• André Lurton at Château Bonnet pioneered cool fermentation techniques, setting the template for modern white Bordeaux
• 1987: Pessac-Léognan carved out of Graves as a standalone AOC, giving formal identity to the region's top dry whites

Bordeaux Blanc AOC spans both banks of the Gironde estuary and its tributaries across the entire Gironde department. The Atlantic-influenced maritime climate provides warm growing seasons moderated by ocean breezes and the buffering effect of the Landes forest to the southwest. Left Bank Graves and Pessac-Léognan sit on deep gravel and sandy soils over clay and limestone subsoil, producing mineral-driven, structured whites. Entre-Deux-Mers, the plateau between the Garonne and Dordogne rivers, features mixed clay-limestone soils on rolling hills ranging from 10 to 100 metres above sea level, yielding fresh, aromatic wines.

• Left Bank Pessac-Léognan: deep gravel soils, forest-buffered microclimate, cooler sites dedicated to white varieties
• Entre-Deux-Mers: clay-limestone and alluvial soils across 132 communes, rolling hills, rivers providing natural temperature regulation
• Maritime Atlantic climate brings moderate temperatures, though climate change is accelerating ripening across the region
• Elevation in Entre-Deux-Mers ranges from 10 to 100 metres above sea level, creating diverse microclimates

Sauvignon Blanc and Sémillon each account for roughly 42% of white plantings, with Muscadelle at around 9%. Sauvignon Blanc delivers herbaceous aromatics, citrus, and bracing acidity in unoaked styles. Sémillon adds weight, texture, and aging potential, developing waxy, honeyed, and nutty characters with bottle age. Secondary varieties including Sauvignon Gris, Colombard, Ugni Blanc, and Mauzac can comprise up to 30% of a blend. Unoaked Bordeaux Blanc is typically Sauvignon Blanc-dominant and made for early drinking, while barrel-fermented Graves and Pessac-Léognan expressions with higher Sémillon proportions can age for a decade or more.

• Unoaked style: Sauvignon Blanc-dominant, stainless steel fermented at low temperatures, fresh citrus and herbal profile
• Barrel-fermented style: higher Sémillon content, fermented and aged in French oak, broader texture and greater aging potential
• Sémillon-dominant blends from top Graves estates develop honeyed, waxy, and nutty complexity over 10 or more years
• Muscadelle contributes floral lift and aromatic intrigue, though it represents a minority of plantings

Domaine de Chevalier (Pessac-Léognan) is one of the benchmarks for white Bordeaux, producing around 1,200 cases per year from five hectares of Sauvignon Blanc and Sémillon; the wine is barrel-fermented and aged for 18 months in 35% new French oak. The estate has been a Cru Classé de Graves since the 1953 and 1959 classifications. In Entre-Deux-Mers, Château Bonnet (Lurton family, in the family since 1897) set the modern standard for clean, aromatic white Bordeaux through cold fermentation techniques. Château Thieuley, managed by the Courselle family since 1950 and now overseen by sisters Sylvie and Marie Courselle, produces both Entre-Deux-Mers and Bordeaux Blanc from an 83-hectare estate.

• Domaine de Chevalier Blanc: 5 ha, 70% Sauvignon Blanc and 30% Sémillon, 18 months in 35% new French oak, Cru Classé de Graves
• Château Bonnet: Lurton family flagship in Entre-Deux-Mers since 1897, pioneered cold fermentation and aromatic dry white style
• Château Thieuley: Courselle family since 1950, 83 hectares, produces both Entre-Deux-Mers and Bordeaux Blanc cuvées
• Pessac-Léognan tier includes Château Haut-Brion Blanc, Château La Mission Haut-Brion Blanc, and Domaine de Chevalier among the region's most collectible whites

Bordeaux Blanc AOC regulations require alcohol between 10% and 13% ABV, a maximum yield of 55 hl/ha, and a residual sugar cap of 4g/L for dry classification. Principal varieties are Sauvignon Blanc, Sémillon, and Muscadelle; secondary varieties including Colombard, Ugni Blanc, Mauzac, Sauvignon Gris, and Merlot Blanc may collectively make up no more than 30% of the blend. Entre-Deux-Mers AOC has its own stricter production criteria, including minimum vine density requirements. Pessac-Léognan, created as an independent AOC in 1987, encompasses all châteaux listed in the 1953 and 1959 Graves classifications and is entirely distinct from the generic Bordeaux Blanc AOC.

• Maximum yield: 55 hl/ha; alcohol 10 to 13% ABV; max 4g/L residual sugar for dry designation
• Secondary varieties (Colombard, Ugni Blanc, Mauzac, Sauvignon Gris, Merlot Blanc) capped at 30% of total blend
• Entre-Deux-Mers AOC requires stricter vine density and applies to dry whites only; red wines in the zone gained AOC Entre-Deux-Mers status from the 2023 vintage
• Pessac-Léognan AOC (est. 1987) covers all 1953 and 1959 Graves classed growths and is a fully independent appellation
