i was thinking that we maybe could do an extract brew there, not in a get up in front of everyone and tell them how to do it way but just kinda in the background so that any ppl who may be there will be able to see just how easy brewing beer actually is, it's a little more advanced than kit brewing i know but the boiling wort and malty smell might intrigue ppl and get them asking questions about the process.
either way i think a bottling demo might be a good idea. every non brewer i meet seems fascinated by the fact that old beer bottles can be used again and that i without the aid of any giant guinness type machines can actually get the cap on them.
