4/18/13, 2:26 PM - I agree - Tesco's pricing policy seems to be "double it and then later sell it at the correct price with a half price sale sticker", I normally avoid them completely.

This was a recommendation from Jancis Robinson - I have dug out another bottle tonight and tried it (this is the third bottle that I have drunk of this wine): there is a degree of bottle variation - the first one was quite a bit denser and more youthful, the second and third bottles are a bit more aged - however, with an hour or so in the decanter the wine takes on a bit more body. I see that the £10 "deal" is back on again - I might have another case. Not a great wine, but a jolly good one for the price.
