Yeah that's right - it's around 6% if memory serves me right.
Just been reading up on them and apparently they're available as part of a promotional deal throughout September in all Weatherspoons. At £2.49 for a 330ml can I'd urge anyone reading this thread who is a beer fan to go purchase a couple of cans it really is that good. I also read they interviewed the bar manager of the Edinburgh branch who said up until this, their best selling 330ml can was Irn Bru (figures) he also seemed to think the stemmed glasses they've bought in to serve these will "walk out of the door"
He might be right . . . . . . .
