Funnily enough I was just talking about Murphy's the other day to somebody and was saying how scarce it is. Grandfather used to often have that in instead of Guinness. Uncle who isn't much of a drinker used to have the occasional Mackesons.
As I say I don't drink too much these days but do quite like the odd one. Out of the Brewdog line I'd recommend the Elvis in the red can. Think it's got grapefruit in it and I hate grapefruit, but love the taste of the beer. 6.5% mind..... so know you've had a couple. Just trying a 'Lost Lager' from Brewdog as they didn't have any Elvis in the Tesco Express. Not anywhere near as nice as Elvis, but 10 x 440mm cans for £9 with a clubcard it beats anything else in that price range by a margin in my opinion.
