Nice Spanish red - Castillo de Calatrava.
Have you tried Argento (Argentinia) MALBEC?
Very nice for less than a fiver.
Not tried that one yet.
But my system of choosing wine
1, colour - is it red or red
2, Price, (is it on offer)
3, country - (my only attempt to be a wine buff

)
5, how it looks - nice bottle
6, have I got the money in my pocket.
this one was done by No's - 2 & 3
But the main factor -2, PRICE - Sainsbury 1/2 price - so less than £5.
