UGH at the alcohol-free/low alcohol wines. NEVER ever found one that is drinkable, in supermarkets etc at least.
But this website looks really good: www.alcoholfree.co.uk/ - AngryFeet - the one you mention is the same price on there so perhaps it is the one you found?
I like the fact they admit that some stuff can be dire - which hopefully means (I have no idea, I've not tried them) that perhaps their stuff is a lot better:
"We know you might be worried about buying a case of alcohol-free drinks that you may not like.
And we know you've probably tried the cheap drinks some of the supermarkets offer and you're worried ours taste as bad (they don't, we promise).
That's why we offer Free UK Returns.
Now you can try our drinks and if you don't enjoy them we'll collect the rest for free and refund you for the returned bottles."
They seem to have a mixed box of stout/dark ales which sounds pretty good - the pregnancy/breastfeeding benefits of Guinness without the alcohol perhaps!!
Although I do cheerfully drink a single mid-strength (2.8%) can of Guinness once or twice a week once out the second trimester, I know that's not for everyone's personal risk levels though!
