Tonight my friend said it was my turn to buy the wine. I went to the supermarket and got smacked in the face by option paralysis.
My friend gave me some key words to look for.
In the end we got two bottles. One for a fiver and one for €9. So far we've opened the cheap one and it's entirely drinkable.
Mission accomplished.
@quixoticgeek I'm not keen on Spanish wines, but I think that's mostly because I don't know what key words to look for, and because the greedy buggers keep the good stuff for themselves.
