A longer day-trip option: Saumur-Champigny is the Loire's great Cabernet Franc heartland, producing lighter-bodied, more aromatic expressions of the same grape that anchors Saint-Emilion's Right Bank. Domaine Filliatreau, Chateau Hureau, and Domaine des Roches Neuves are the reference producers. Contrasting the Loire style against Bordeaux Cabernet Franc is valuable for any serious wine student.
Pours: Domaine Filliatreau Saumur-Champigny Vieilles Vignes, Domaine des Roches Neuves L'Insolite
The Charente's Cognac town and its surrounding Grande Champagne and Petite Champagne crus, home to the great Cognac houses (Hennessy, Remy Martin, Prunier) and smaller grower distillers. A full-day trip from Bordeaux covers two house visits with Charentais pot-still tours and an aged XO tasting.
Pours: Hennessy XO, Remy Martin VSOP, Prunier Grande Champagne Vintage
The Bergerac wine region in the Dordogne valley, immediately east of Bordeaux, produces red and white wines from the same grape varieties: Cabernet Sauvignon, Merlot, Sauvignon Blanc, Semillon. The Monbazillac appellation produces botrytised dessert wines that are stylistically similar to Sauternes at far lower prices.
Pours: Chateau Tour des Gendres (Bergerac rouge), Chateau de Tirecul La Graviere (Monbazillac), Chateau Bellingard Monbazillac
Gascony's Bas Armagnac appellation in the Gers produces France's oldest brandy, distilled in the continuous alembic armagnacais style rather than Cognac's double-distillation. Single-vintage Armagnacs dating back to the 1920s are available from estate distillers including Domaine de Menard and Domaine d'Ognoas.
Pours: Domaine de Menard Bas Armagnac Vintage 2000, Domaine d'Ognoas (state-owned, historic)
Cahors, the ancestral home of Malbec before phylloxera devastated it in Bordeaux, now produces some of France's most powerful and age-worthy red wines from Malbec (locally called Cot). The Lot river valley terroir produces structured, tannic, mineral expressions very different from Argentina's version.
Pours: Chateau Lagrezette Malbec, Clos Triguedina Prince Probus Malbec, Chateau du Cedre Cahors
