Blind Tasting Wine Recommendations

[skilly1]

I'm going do a blind wine tasting evening - 6 bottles of wine (3 red, 3 white) wrapped in kitchen foil. Teams then have to guess from the taste/smell and looking at the bottle shape:


Country of origin
Type of Grape
Also rate the wine (1-10)
Price
Any suggestions for some wine to buy? It has to be available from a supermarket/ high street booze shop (preferably the same one !)
I need one cheap, One medium (£8 plus) and one expensive(relatively - £20 max). Thinking of putting a British wine in there somewhere.

Any good suggestions, maybe a curved ball option?

Thanks for all of the replies, good idea to pick quite obvious differences to make it easier. Also like the idea of have description to guess.
