I have vague memories of getting merry on Broadside when it was a guest beer at the local.
Not sure I've this brew before, but I'm a big fan of the brewery
(it's a shame "Dark Side of the Moose" isn't available):
Purple Moose of Porthmadog – Glaslyn Ale 4.2% abv
Likewise the brews from Salopian of Shrewsbury. The Bhurt Pore[/url] quite often has something from them on.
Would be rude not to try one of the perrys as well, given it'll be proper stuff and not the trendy pish that has appeared in bars these days.
