Chapter 14: The Dordogne and South West France, The Vine

Why South West France Matters

South West France is a diverse collection of appellations spread across the hinterland east and south of Bordeaux. For the exam, this region matters for three main reasons:

Value comparison with Bordeaux: regions like Bergerac use the same grapes and similar styles as Bordeaux, but at a fraction of the price. The exam may ask you to explain why.
Unique grape varieties: Tannat (Madiran), Malbec/Côt (Cahors), and the Manseng family (Jurançon) are grapes you won't find in Bordeaux, and each produces a distinctive style.
Sweet wine production: Monbazillac and Jurançon both produce notable sweet wines, adding to the range of styles you need to know.

Key fact: Historically, Bordeaux merchants (the négociants) used their political power to block wines from the South West from being shipped downriver until after Bordeaux's own wines had been sold. This kept South West wines cheap and obscure for centuries, a historical disadvantage that continues to affect pricing today.

Climate

South West France spans a range of climatic influences, which helps explain the diversity of wine styles:

Western areas (Bergerac): Maritime influence from the Atlantic, similar to Bordeaux. Moderate temperatures, significant rainfall, risk of rot. Good conditions for Bordeaux grape varieties.
Inland areas (Cahors): More continental. Warmer summers, colder winters. Less maritime influence means lower rainfall and a longer, drier ripening period. Suits thick-skinned grapes like Malbec.
Southern areas near the Pyrenees (Madiran, Jurançon): Influenced by both the Atlantic and the mountains. Warm autumns are critical for Jurançon's late-harvest sweet wines. The föhn effect, warm, dry winds descending from the Pyrenees, helps dry grapes on the vine.

Autumn warmth and sweet wine: Both Monbazillac (near Bergerac) and Jurançon (near the Pyrenees) rely on warm, dry autumns to make sweet wines, but through different mechanisms. Monbazillac uses botrytis (like Sauternes), while Jurançon relies on the passerillage technique, grapes are left on the vine to dry and concentrate their sugars in the warm autumn winds.

Bergerac

Bergerac sits immediately east of Bordeaux along the Dordogne river. In many ways, it is Bordeaux's twin, same climate, same grapes, same winemaking. The key difference is price.

Red Bergerac

Red Bordeaux grapes Value

Blends of Merlot, Cabernet Sauvignon, and Cabernet Franc: exactly like Bordeaux. The wines are typically medium-bodied with plum and blackberry fruit, moderate tannin, and good acidity. Merlot tends to dominate, as in Bordeaux's Right Bank.

Style: Fresh, fruit-driven reds at entry level. Pécharmant (a sub-appellation within Bergerac) produces more structured, age-worthy reds from hillside vineyards with iron-rich clay soils.

White Bergerac

White Dry & sweet styles

Dry whites from Sauvignon Blanc and Sémillon, similar to white Bordeaux. Fresh, crisp, citrusy. Can offer excellent value as an alternative to Bordeaux Blanc or Entre-Deux-Mers.

Why is Bergerac cheaper than Bordeaux? The wines are made from the same grapes in virtually the same conditions, but the Bergerac name does not carry the prestige (or the inflated land prices) of Bordeaux. For the exam, this is a straightforward example of how brand recognition and appellation prestige affect wine pricing independently of actual quality.

Monbazillac

Monbazillac is a sub-appellation within Bergerac, located on south-facing slopes overlooking the Dordogne river. It produces sweet white wines from botrytis-affected grapes: essentially the same concept as Sauternes, but at a fraction of the price.

Monbazillac Sweet Wines

White Sweet / Botrytis

Grapes: Sémillon (dominant), Sauvignon Blanc, Muscadelle, the same trio as Sauternes.

How it's made: Morning mists rising from the Dordogne river encourage noble rot (botrytis cinerea) on the thin-skinned Sémillon grapes. Afternoon sun dries the grapes, concentrating sugars and flavours. Grapes are picked in multiple passes through the vineyard.

Flavour profile: Honey, apricot, marmalade, candied citrus. Rich sweetness balanced by acidity. The best examples can age for a decade or more.

Price: Typically a third to a quarter of the price of Sauternes, making it one of the best value sweet wines in France.

📝

Exam Angle

If the exam asks you to discuss sweet wines produced by noble rot in France, Monbazillac is an excellent comparison to Sauternes: same grapes, same technique, similar flavour profile, dramatically different price. The reason for the price difference is primarily appellation prestige and global demand: Sauternes has Château d'Yquem and centuries of fame behind it.

Cahors

Cahors is Malbec's original home. While Argentina made Malbec famous worldwide, the grape has been grown in the Lot Valley near Cahors for centuries, where it is known locally as Côt (or Auxerrois in older texts).

Cahors Red Wines

Red Malbec / Côt Must be ≥70% Malbec

Grape rules: Cahors AOP wines must contain at least 70% Malbec (Côt), with Merlot and Tannat permitted as blending partners.

Climate: More continental than Bordeaux. Warmer summers and colder winters, with lower rainfall. This allows Malbec to ripen more fully than it historically did in Bordeaux.

Soil: The best vineyards are on the limestone causse (plateau) above the Lot river valley. The valley floor has more alluvial soils and produces lighter wines.

Style: Deeply coloured, tannic reds with dark plum, blackberry, and sometimes violet character. More austere and structured than Argentine Malbec, with higher tannin and acidity. Historically known as "black wine" (vin noir) because of its intense colour and density.

Cahors vs Argentine Malbec: This is a natural exam comparison. Cahors Malbec is typically higher in acidity, more tannic, more restrained, and more structured. Argentine Malbec (especially from Mendoza) is usually softer, fruitier, riper, and more immediately approachable. The difference comes from climate (cooler and more variable in Cahors) and winemaking tradition (Cahors tends to use more conventional, sometimes rustic techniques).

📝

Exam Tip

Remember the local name: Malbec is called Côt in Cahors and the Loire Valley, and Auxerrois in some older references. The WSET exam may use any of these names. They all refer to the same grape.

Marcillac

Marcillac AOP

Red Fer Servadou (Mansois)

A small, remote appellation in the Aveyron department. The dominant grape is Fer Servadou (locally called Mansois), which produces medium-bodied reds with distinctive raspberry, blackcurrant, and green pepper notes. The wines can be rustic, with firm tannins and bright acidity.

Marcillac is a minor topic for the exam, but it demonstrates the South West's tradition of preserving unique local grape varieties that exist nowhere else.

Madiran

Madiran is the home of Tannat: one of the most tannic red grape varieties in the world. Located in the foothills of the Pyrenees, it produces deeply coloured, powerfully structured red wines that traditionally needed a long period of bottle ageing to soften.

Madiran Red Wines

Red Tannat Extremely tannic

Grape rules: Madiran must contain at least 60–80% Tannat (depending on the vintage declaration), blended with Cabernet Sauvignon, Cabernet Franc, and/or Fer Servadou.

Style: Deep, inky colour. High tannin (very high in traditional examples). Dark fruit, blackberry, black plum, dark cherry. With ageing, can develop leather, spice, and earthy complexity.

Modern evolution: Today, many producers use techniques to soften Tannat's ferocious tannins, micro-oxygenation (a technique actually invented in Madiran by Patrick Ducournau), riper grape selection, and more careful extraction. Modern Madiran is still robust but much more approachable in youth than the traditional style.

Micro-oxygenation: This technique involves introducing tiny, controlled amounts of oxygen into the wine during or after fermentation. It softens harsh tannins by encouraging polymerisation (tannin molecules linking together to form longer, softer chains). Invented in Madiran in the early 1990s, it is now used worldwide for tannic red wines. If the exam mentions micro-oxygenation, Madiran is the place to connect it to.

Pacherenc du Vic-Bilh

White Dry & sweet

The white wine appellation that overlaps with Madiran. Wines are made from Petit Manseng, Gros Manseng, Arrufiac, and Courbu: local varieties not found in Bordeaux. Dry versions are aromatic and fresh. Sweet versions (moelleux) are made from late-harvested grapes, with honey, tropical fruit, and spice character.

Jurançon

In the foothills of the Pyrenees, Jurançon produces both dry and sweet white wines from grapes that are uniquely adapted to the mountain climate. The sweet wines are the appellation's claim to fame.

Jurançon Sec (Dry)

White Gros Manseng

Dry whites made primarily from Gros Manseng, with some Petit Manseng and Courbu. Fresh, aromatic, with citrus and exotic fruit notes (grapefruit, passion fruit) and high acidity. These are lively, food-friendly wines.

Jurançon (Sweet)

White Sweet / Passerillage Petit Manseng

The sweet wines of Jurançon are made from Petit Manseng, a small-berried grape with very thick skin. The grapes remain on the vine into November and sometimes December, drying in the warm föhn winds that descend from the Pyrenees. This passerillage (on-vine drying) concentrates the sugars and flavours without relying on botrytis.

Flavour profile: Pronounced aromas of apricot, grapefruit, pineapple, and spicy notes, often accompanied by honey. The wines have intense sweetness balanced by very high acidity, Petit Manseng retains its acidity even at extreme ripeness levels. This acidity gives Jurançon sweet wines remarkable freshness and ageing potential.

📝

Exam Angle

Jurançon is a useful comparison when the exam asks about different methods of making sweet wine. Unlike Sauternes and Monbazillac (botrytis), Jurançon uses passerillage on the vine. Unlike German Trockenbeerenauslese (which also uses botrytis) or Vin de Paille (off-vine drying), Jurançon's grapes dry on the vine in the mountain winds. Know which technique goes with which region.

South West France at a Glance

Appellation	Key Grape(s)	Style	Comparison
Bergerac (red)	Merlot, Cabernet Sauvignon, Cabernet Franc	Medium-bodied red blend	Like affordable Bordeaux
Monbazillac	Sémillon, Sauvignon Blanc	Botrytis sweet white	Like affordable Sauternes
Cahors	Malbec (Côt) ≥70%	Dark, tannic, structured red	More austere than Argentine Malbec
Madiran	Tannat ≥60%	Deeply coloured, very tannic red	Like Uruguayan Tannat (but the original)
Jurançon Sec	Gros Manseng	Dry, aromatic white	Unique, no close parallel
Jurançon (sweet)	Petit Manseng	Sweet white (passerillage)	Different method from Sauternes

Why South West France Represents Value

For the exam, understanding why South West wines are less expensive than their Bordeaux equivalents is an important quality/price question:

Lower land prices: vineyard land in Bergerac or Cahors costs a fraction of what it costs in Bordeaux, keeping production costs down
Less brand recognition: global consumers know "Bordeaux" but not "Bergerac." Less demand means lower prices.
Historical disadvantage: centuries of being blocked from markets by Bordeaux's political power left these regions with less established reputations
No classification system: unlike Bordeaux (with its prestigious 1855 Classification), South West appellations have no famous hierarchy to drive collector demand
Smaller export markets: many South West wines are consumed locally or within France, limiting international exposure

The opportunity: For a consumer, South West France is one of the best value plays in French wine. The quality gap with Bordeaux has narrowed significantly, while the price gap remains wide. For the exam, this is a textbook example of how factors beyond wine quality (reputation, classification, brand recognition) drive pricing.

Aroma Kit Integration

👃

South West France Aroma Session (20 min)

Pull these from your kit: black plum, blackberry, violet, pepper, dried fruit, honey. Smell each individually. The dark, intense fruit aromas (plum, blackberry) are markers for Malbec and Tannat. Honey and dried fruit connect to the sweet wine styles.

Wine drill: If you can find a Cahors Malbec, taste it alongside an Argentine Malbec at a similar price point. Write SAT notes for both. Pay attention to: tannin level (Cahors will likely be higher), acidity (Cahors higher), fruit ripeness (Argentina riper), and body. This directly trains the comparison skill the exam tests.

Sweet wine option: If you can find a Monbazillac (often ~$12–18 for a half bottle), taste it and compare your notes to the Sauternes SAT profile from Chapter 13.
