Loupiac AOC (sweet whites, right bank of Garonne)
Bordeaux's right bank treasure producing botrytized sweet whites of genuine elegance, sitting directly across the Garonne from Barsac and Sauternes.
Loupiac AOC sits on the right bank of the Garonne, around 30 to 40 kilometres southeast of Bordeaux, producing exclusively sweet white wines from Sémillon, Sauvignon Blanc, and Muscadelle. Covering approximately 344 hectares within a single commune, it benefits from autumn mists that encourage Botrytis cinerea, producing wines of real aromatic complexity and aging potential at prices considerably below Sauternes.
- Located in the Entre-Deux-Mers region, approximately 30 to 40 km southeast of Bordeaux on the right bank of the Garonne, directly opposite Barsac
- Appellation covers approximately 344 hectares of vineyards within the single commune of Loupiac, with a maximum permitted yield of 40 hl/ha
- AOC status established by official decree on 11 September 1936, exclusively for sweet white wines
- Wines must contain a minimum of 45 g/L residual sugar at bottling, with Sémillon the dominant variety at roughly 85% of blends
- Permitted grape varieties are Sémillon, Sauvignon Blanc, Muscadelle, and Sauvignon Gris
- Clay-limestone slopes and gravelly soils face south, providing ideal drainage and sun exposure; proximity to the Garonne generates autumn morning mists essential for Botrytis development
- Celebrated vintages include 1989, 1990, 1997, 2001, 2007, and 2009, with 2005 and 2010 also highly regarded
History & Heritage
Loupiac's viticultural history reaches back to Roman times, evidenced by the remains of a Gallo-Roman villa in the commune. Medieval trade between Bordeaux and England helped establish the reputation of these wines, and in the 17th century Dutch merchants boosted production while introducing barrel and bottle aging using sulfur. In 1832, the scholar Jullien classified Loupiac wines at the level of Sauternes second growths, and by the 19th century the Bordeaux bourgeoisie built extravagant estates on the hillsides. The appellation was formally created by official decree on 11 September 1936.
- Gallo-Roman villa remains in Loupiac confirm vine cultivation dating to Antiquity
- Medieval English trade routes elevated the appellation's early reputation for sweet wines
- Jullien's 1832 classification placed Loupiac wines alongside Sauternes second growths, confirming early quality recognition
- AOC formally established 11 September 1936, within boundaries set by the Bordeaux Court of Appeal
Geography & Climate
Loupiac occupies clay-limestone slopes and plateaux on the right bank of the Garonne, around 30 to 40 kilometres southeast of Bordeaux, sitting between Cadillac to the northwest and Sainte-Croix-du-Mont to the south. The vineyards face predominantly south and enjoy excellent natural drainage. The temperate oceanic climate is shaped by the proximity of the Garonne, which generates humid autumn conditions favourable for Botrytis cinerea. Morning mists form from late September onwards, followed by warm afternoon sunshine that concentrates sugars in the affected grapes.
- Limestone subsoil with gravelly-clay slopes provides superb drainage and heat retention for slow, even ripening
- Garonne River proximity creates morning mists from September through November, promoting noble rot development
- South-facing aspect maximises sun exposure, helping concentrate sugars after botrytis infection
- Appellation forms an enclave within the wider Premières Côtes de Bordeaux zone, bounded by Cadillac and Sainte-Croix-du-Mont
Key Grapes & Wine Styles
Sémillon dominates Loupiac blends at approximately 85%, contributing honeyed texture, waxy richness, and the thick skin that makes it particularly receptive to botrytis infection. Sauvignon Blanc, typically around 10% of the blend, adds lively acidity and herbaceous citrus notes that prevent the wines from feeling cloying. Muscadelle contributes delicate floral complexity with notes of orange blossom and rose. Sauvignon Gris is also permitted. Loupiac wines are described as slightly more airy and less opulent than Sauternes, with a particular emphasis on balance between sweetness and freshness.
- Sémillon: approximately 85% of blends; provides honeyed richness, waxy texture, and receptivity to botrytis
- Sauvignon Blanc: approximately 10% of blends; contributes bright acidity and citrus-herbaceous character to balance sweetness
- Muscadelle: approximately 5% of blends; adds floral complexity with orange blossom and rose notes
- Harvest is carried out by hand in successive passes (tries successives), selecting only fully botrytised grapes
Notable Producers
Château de Ricaud is the most internationally recognised estate in Loupiac. Alain Thiénot purchased the property in 1980, having fallen for a bottle of the 1929 vintage, and in 2007 joined forces with négociant Dourthe in an ambitious quality-focused redevelopment. Château du Cros, owned by the Boyer family since 1921, is one of the appellation's largest and most consistent producers, with around 60 hectares of vines and old Sémillon plantings. Château Loupiac-Gaudiet and Clos Jean are also recognised estates within the appellation.
- Château de Ricaud: benchmark estate, acquired by Alain Thiénot in 1980, partnered with Dourthe since 2007; wines harvested by hand with full botrytis selection
- Château du Cros: Boyer family property since 1921; around 60 hectares of clay-limestone vines with multiple hand-picking passes per harvest
- Château Loupiac-Gaudiet: well-regarded for consistent botrytis character and accessible pricing
- Clos Jean: established Loupiac estate recognised within the appellation
Wine Laws & Classification
Loupiac AOC, established by decree on 11 September 1936, is reserved exclusively for sweet white wines produced within the single commune of Loupiac. Wines must contain a minimum of 45 g/L residual sugar at bottling, and the maximum permitted yield is 40 hl/ha, higher than Sauternes but with must-weight requirements that are actually more stringent than those of Sauternes. Planting density must reach at least 5,000 vines per hectare. Chaptalization is permitted in limited circumstances during poor vintages. Loupiac sits within the Entre-Deux-Mers region and forms an enclave in the Premières Côtes de Bordeaux zone.
- Exclusively sweet white wine appellation: dry wines produced in the commune cannot carry the Loupiac AOC name
- Minimum residual sugar: 45 g/L at bottling, requiring genuine botrytis-driven concentration
- Must-weight thresholds before harvest are stricter than Sauternes: 245 g/L for Sémillon, 229 g/L for other varieties
- Maximum yield of 40 hl/ha; planting density of at least 5,000 vines per hectare required
Visiting & Culture
Loupiac is a rural, small-scale appellation with a genuinely welcoming atmosphere. The commune is worth visiting for more than its wines: the vestiges of a Gallo-Roman villa and the Saint-Pierre church are notable cultural landmarks. Château du Cros offers cellar visits and tastings throughout the year, and a walking trail through the vineyards leads up to the ruined medieval Château du Cros, which sits at the highest viewpoint over the Garonne in the Gironde. Visiting during September and October allows guests to observe the selective harvest and see botrytis development firsthand.
- Gallo-Roman villa remains and the Saint-Pierre church offer cultural interest beyond wine
- Château du Cros welcomes visitors year-round for cellar tours and tastings, with a vineyard walking trail to the medieval hilltop ruins
- Harvest season from late September through November is the ideal time to observe successive botrytis-selective picking
- The appellation's small scale, with around 18 estates recorded by the official trade body, ensures an intimate, unhurried visitor experience
Loupiac wines are golden in colour with aromas of ripe apricot, white peach, candied citrus, acacia blossom, and honey. The palate is rich and unctuous but retains a lively acidity that prevents the sweetness from becoming heavy. With age, the bouquet develops secondary notes of dried fruit, gingerbread, toasted hazelnut, and prune, with a long and persistent finish. Compared to Sauternes, Loupiac tends toward a slightly lighter, more airy profile that emphasises freshness alongside sweetness.
