Cellar bar for Cellarman

I am doing a tasting tonight at Ryan's Cellar Bar. The group will number around 60, which is big for a tasting but should be fun. I generally go through the history of beer, how beer is made, the styles of beer and, of course, the tasting itself. Usually throws up a few nuggets. For example, did you know 'minding your P's and Q's' comes from a beer related situation? The origins of 'small beer' are interesting and the punishment for serving bad beer in Babylon would put Environmental Health to shame!!
