Cadillac Côtes de Bordeaux AOC (Reds)

Winemaking on the Garonne's right bank has ancient roots, with vines cultivated here from the Gallo-Roman period and a flourishing trade driven by English and later Dutch demand throughout the Middle Ages and into the 17th and 18th centuries. The modern appellation history is more recent: red wines from these 39 communes were long labelled as Premières Côtes de Bordeaux until 2009, when the newly ratified Côtes de Bordeaux umbrella appellation gave the area its current identity as Cadillac Côtes de Bordeaux. The process had begun officially in 1985, when growers from Blaye, Castillon, Francs, and Cadillac formed the Association des Côtes de Bordeaux to promote their wines collectively. A notable local connection links the area to the wider world: Antoine de Lamothe-Cadillac, born in this region, founded the settlement that became Detroit in 1701, and the famous car brand eventually took his name.

• Vines cultivated in the area from the Gallo-Roman period; English appetite for local wines drove medieval trade
• Dutch merchants became important customers in the 17th and 18th centuries, further growing the region's wine economy
• Red wines sold as Premières Côtes de Bordeaux until 2009; the Cadillac Côtes de Bordeaux title came into force with the Côtes de Bordeaux AOC
• The Côtes de Bordeaux Association was founded in 1985 by producers from Blaye, Castillon, Francs, and Cadillac to promote their wines under a shared banner

Cadillac Côtes de Bordeaux occupies a long, narrow strip on the right (east) bank of the Garonne River, running for roughly 60 kilometres and never more than 5 kilometres wide. The appellation lies west of the Entre-Deux-Mers plateau and sits opposite some of the Graves and Sauternes appellations across the river. The sloping terrain, for which the broader Côtes de Bordeaux family is named, provides predominantly south and southwest-facing exposures with high sunshine hours. Vineyards climb to elevations of up to 127 metres, creating distinct microclimates. The soil mosaic is key to the appellation's character: gravelly soils on the peaks favour Cabernet varieties and structured wines, clay-limestone at mid-slope suits Merlot, and fine gravel mixed with silica at the foot of the slopes allows good drainage. The proximity of the Garonne moderates temperatures and generates autumn morning mists that benefit botrytis development in the neighbouring sweet wine enclaves.

• Location: right bank of the Garonne, 39 communes, stretching from Bassens (north) to Saint-Maixant (south), roughly 30 km south of Bordeaux city
• Slope orientation predominantly south and southwest, providing high sun exposure; elevations up to 127 metres above sea level
• Soil profile: gravelly on hilltops, clay-limestone on mid-slopes, fine gravel and silica at slope bases; all favour drainage and mineral complexity
• Climate: temperate oceanic, moderated by the Garonne; mild winters, warm summers without excess, and approximately 240 sunny days per year

The appellation is exclusively red. Merlot dominates at around 55% of plantings, delivering the soft tannins, ripe red and dark fruit, and early accessibility that define the appellation's signature style. Cabernet Sauvignon (25%) adds structure and dark fruit concentration, particularly on the gravelly hilltop parcels, while Cabernet Franc (15%) contributes aromatic complexity and freshness. Malbec accounts for a small share (5%) and adds colour and spice in minor blending roles. The resulting wines are medium-bodied, supple, and fruit-forward, with cherry, plum, and blackcurrant fruit from the Merlot component and hints of graphite, pepper, and licorice from the Cabernet varieties. They are approachable from release but can reward a few years of cellaring.

• Merlot (55%) provides round, fruit-forward character and soft tannins that define the appellation's accessible style
• Cabernet Sauvignon (25%) brings backbone and dark fruit, particularly expressive on gravelly hilltop soils
• Cabernet Franc (15%) adds aromatic lift, freshness, and complexity to blends
• Wines are supple and approachable young; the best examples from clay-limestone plots reward three to eight years of bottle age

The appellation counts around 118 estates producing across conventional, organic, and biodynamic farming, with an average estate size of 11 hectares. Among the most recognised names are Château Fayau, a 41-hectare estate in Cadillac owned by the Medeville family since 1826; Château Reynon, a 33-hectare property associated with the late oenologist Denis Dubourdieu and now run by his family; and Château Carsin, Château Carignan, Château Birot, Château du Grand Mouëys, Château Lezongars, Château Puy Bardens, and Château Tanesse. The appellation's single cooperative and several multi-generational family estates ensure a range from everyday-value bottlings to more structured, oak-aged cuvées. Château bottling is mandatory, which underpins quality consistency across the board.

• Château Fayau (Medeville family, established 1826): one of the appellation's most recognised estates, with a 41-hectare vineyard in Cadillac
• Château Reynon (Denis Dubourdieu Domaines, Béguey): 33-hectare estate with deep gravel soils; known for Merlot-dominant reds with a velvety, complex profile
• Château Carignan and Château Carsin: widely cited quality producers within the appellation
• All wines must be château-bottled by AOC regulation — a distinctive requirement within Bordeaux that supports estate identity and traceability

Cadillac Côtes de Bordeaux falls under the Côtes de Bordeaux AOC framework ratified in 2009. Red wines may only use the six classic Bordeaux red varieties: Merlot, Cabernet Sauvignon, Cabernet Franc, Malbec, Petit Verdot, and Carmenère. Château bottling is obligatory, making this one of the few Bordeaux appellations where estate bottling is a legal requirement rather than voluntary practice. Producers may also choose to label their wine under the broader Côtes de Bordeaux umbrella designation rather than the Cadillac geographic name. There is no internal classification hierarchy within the appellation; unlike Saint-Émilion, no Grand Cru or classified-growth tier exists, and all producers operate under identical regulatory parameters.

• AOC established 2009 under the Côtes de Bordeaux umbrella, replacing Premières Côtes de Bordeaux for reds
• Permitted red varieties: Merlot, Cabernet Sauvignon, Cabernet Franc, Malbec, Petit Verdot, Carmenère
• Château bottling is mandatory — a legally required distinction that sets this appellation apart within Bordeaux
• No internal classification hierarchy; producers may alternatively label wines as Côtes de Bordeaux rather than Cadillac Côtes de Bordeaux

The town of Cadillac-sur-Garonne lies approximately 30 kilometres south of Bordeaux city and is easily reached via the A62 motorway (exit Podensac). The town takes its name from Antoine de Lamothe-Cadillac, the local-born explorer who founded Detroit in 1701 and whose adopted name eventually inspired the famous American car brand. Dominating the town is the Château Ducal de Cadillac, commissioned by Jean-Louis de Nogaret de La Valette, the first Duke of Épernon, with construction beginning in 1599. The castle later served as a women's prison from 1820 to 1952 and is now a listed national monument open to visitors year-round. The Maison des Vins de Cadillac, located in the town, serves as the appellation's tasting centre and producer directory, providing an excellent entry point for wine tourism across the 39 communes.

• Château Ducal de Cadillac: construction began 1599 on the orders of Jean-Louis de Nogaret de La Valette, first Duke of Épernon; listed as a national historic monument; open year-round
• The castle served as a women's prison from 1820 to 1952 before restoration; it now features original 17th-century tapestries and monumental carved fireplaces
• Cadillac-sur-Garonne is the origin of the name adopted by Antoine de Lamothe-Cadillac, founder of Detroit (1701) — the indirect inspiration for the car brand
