We received a present from a neighbour last weekend, a Pascual Toso Malbec 2009 from Mendoza, website here. After being opened and decanted for about an hour and a half we tucked in. Immediately we were impressed. There was some nice plummy fruit, delicate tannins and a long finish, this was a very well balanced wine; reasonably fruit forward in a New World style but with some lovely structure to balance it out.
If you are having a steak or like your Malbecs then you will not go wrong with this wine.
About two weeks ago I picked up a few disparate bottles in Superquinn, Blackrock. We drank the last of these last night. It was a Vina Albali Gran Reserve 1999 (€6). When I bought it I said "This wine is probably very tired... and priced to move, but you never know".
I hate to say I told me so, but I was not wrong. This wine was tired, with not a lot going for it, some fading fruit and vanilla flavours and a sharp, and slightly unpleasant taste on the finish. Herself liked it, but there's no accounting for taste, she married me after all.
**Update - Nov 12 2010 - Saw this Malbec in Donnybrook Fair for €9-99. A steal!
