What French people call "South West" is the part of France from Bordeaux down to Collioure in the Pyrenées along the Spanish border. Cahors is included in this wide region along with Languedoc, Roussillon, Bergerac, Bordeaux and a few other appellations.
First of the top ten selected by the Dussert-Gerber guide for this region is 2005 Château Nozières: "You will appreciate like us this Cahors Château
Nozières 2005 (80% Cot, 20% Merlot on ground argilo-limestone, breeding
out of tanks stainless), of intense dress, with the persistent nose
(morello cherry, violet), well-balanced, fleshy, with ripe tannins,
rich color as out of matter, with the scents of cherry and humus, with
a point of spices, mouthfull. Cahors Ambroise cuvée of Her 2005 is a
success, all in nuances, robust, tasty, very well-balanced with the
nose as in mouth (macerated fruits)."
