What do you mean about this one? Is it the fact they seem to have two versions?
I don't understand why as the label looks identical, but one seems to be 6.5% abv and the other, 5.1%.
The stuff in Tesco is the 6.5% and that is also what the sell in Wetherspoons now, but I did actually have to pull them up on it as I once ordered some stated as 6.5% and when it turned up it was the 5.1% version. They seem to have corrected that now however, as for at least the last year or so its the 6.5% you get. But another shop near here they sell the 5.1% version, I admit I have no idea why.
By the way, I am not bothered about ABV in beer as such, if anything I prefer some of the not so strong ones and you need to be careful, particularly with something like a 6.5% beer as it can catch you out. In Spoons they sell the 660ml bottles of Evlis Juice 6.5% version, its something like 8 units of alchohol if you have just two of those, so although it doesnt seem like you are drinking much, in terms of alcohol you are.
I Also agree about the Punk IPA - its actually not my favourite of their line up, I'll drink it, its okay, but much prefer some of their others.
I think another one they do which is really nice is Lightspeed, which is a Hazy IPA but a lot lighter alchohol wise but got a really fruity flavour.
