The Malbec grape is native to the Cahors area of southern-ish, western-ish France. Originally famous as the "black wine" and was held to be better than its neighbour, Bordeaux. So the Bordelaise stopped it letting be shipped down river for export. Sort of put a crimp on things.
Much later, and up to about 30 years ago the youngsters wrested hold of the vinyards and chais and started replanting and re-equipping. There wine out of there now can be really good. As has often been shown, the French know how to work their vineyards and how to make wine since they opened their minds to new technologies.
One of our xmas wines to go with the bird was a Chateau Ponzac. Presently they are making 3 reds, using grapes from different parts of their vineyard, with different soils and aspects, combined with differences in vinification and storage, but all really great to drink.
The vinyard was literally a few 100 yds from the gite we used last year. The gite owner left us a bottle to try when we arrived, and after trying and enjoying, we stocked up. Enough to bring home a few, sufficient to last until now at least.
Here in UK, we can get Argentinian Malbec from quite few producers. Some can be quite good, but tend to be rather "mass produced", not so much bland but lacking scope.
