I should have said the label and pointed out it's a second bottle wine rather than your first bottle wine. I didn't see any other Malbecs on offer in the Asda I was in. Sorry. Another very decent second bottle wine is the Cepa Lebrel Rioja out of Lidl for £3.99.
I do enjoy a good Rioja, if nothing else than the pronunciation, it's gotta be the coolest wine out! I love the campo vieja whenever it's on offer in Tesco, goes down like Vimto but a brilliant Rioja, I think I'm heading to tesco to get another few bottles
