Cahors is where history and grape identity collide. Once exported via the River Lot to Bordeaux as the “black wine of Cahors,” the region was later squeezed by Bordeaux trade restrictions, then devastated by phylloxera and the 1956 frost. Today it’s a Malbec stronghold: 3,300 ha, with Malbec accounting for 85% of plantings, and Cahors is the only French appellation where Malbec is the principal variety.

Style starts in the landscape: alluvial soils near the River Lot can give higher yields and lower concentration; mid-slopes and the plateau (just under 350 m) move into poorer soils and limestone, bringing lower yields and higher concentration. The climate is warmer and slightly drier than Bordeaux (under 800 mm rainfall), meaning Malbec ripens more regularly and there’s less fungal disease pressure, supporting a higher-than-average share of organic growing (17%).

Regulations and choices create two lanes: Cahors AOC must be at least 70% Malbec (with Merlot and/or Tannat), and destemming is required to avoid harsh tannins from underripe stems—now as much a drought and water-stress issue as a cool-season one. Earlier drinking wines tend to use Merlot and shorter macerations (7–10 days); ageworthy wines push extraction (15–25 days) and may see French oak barriques (vanilla, sweet spice, higher cost) or foudres for slow development without overt oak. Since 2007 the region has marketed itself as “Cahors Malbec,” and that’s the whole point: clarity sells.
