Argentine Malbec reached the public's radar in the 80's-90's thanks to its charming character, juicy fruit and its plush, velvety texture. A type of wine difficult to dislike. It easily became fashionable, making Mendoza's fortune as a wine region. And since then anyone been asked about Malbec would think about Argentina probably also because 70% of it is cultivated there.
Much sturdier than its Argentinian brother, the 'black wine' of Cahors has generally a more difficult character, a rustic feel, less generous fruitiness, spiciness and harsher tannins that need a bit of ageing.
All the wines I have tasted were of surprisingly good quality and extremely fairly priced. I didn't find them that austere but they certainly had exuberant tannins and needed a bit of food (which of course was not missing) to express at their best.
I can reconfirm that these wines were extremely different in style from the Argentine Malbec (one of my favourites) I had when I came back home .
What I found interesting (and the reason that inspired me in writing this post) is the individual characters this grape can show and how the combination of soil, climate, human techniques (i.e. irrigation or not) and local traditions can produce such unusual wines from it.
I'd like to finish saying that I don't think there is a style that is better than the other, it is just a matter of taste. Always drink whatever you like!
Salute!
