When you think of wines from Argentina, you'd be forgiven for thinking immediately of Malbec. The grape has become synonymous with Argentina and, arguably, has become their point of difference. Malbec was a constituent of some Bordeaux blends, but back in France, it's best know in Cahors, who are doing their very best at marketing themselves as the "original" Malbec region. Back to the wine of Argentina, Malbec is so well suited to the warmer temperatures and higher altitude, giving rise to gorgeously rich, fruity wines. Furthermore, they can and do produce some truly premium wines. The higher up in the Andes, the colder the night, which leads to a slower, consistent ripening, a more balanced acidity and defined coloration. Look out for the wines of Catena, and in particular, the Catena "Alta" wines.
