Yeah, I'm kind of with n1mbus on this - that's a fierce amount of beer lads. We'd be happy out with a max of 100ml of each beer per person tasting it, even 50ml, a couple of mouthfuls. Even if everyone only tastes half of the beers we're going to be rat-arsed.
Hell, I'll be rat-arsed on the two obligatory purchased drinks! (why, oh why isn't there something low-alcohol like TSB?! available? <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt="

I presume I'm not the only one with work the following morning <!-- s;) --><img src="{SMILIES_PATH}/icon_wink.gif" alt="

I can come along early to help set up too. I finish work in St James's at 4pm. Would it be worth getting a couple of measuring cups for easier dispensation of small amounts of beer? Probably not, they'd only require rinsing.
