Again, thanks for all the replies and PMs.
Just to clarify, I'm not suggesting bringing homebrew to commercial premises (although I've been served homebrew on commercial premises, but that's another story). But an initial meeting of like-minded folk in a suitable licenced premises would be appropriate. I reckon most homebrewers appreciate proper beer, rather than the CUB swill.
To whiteferret, it depends what you mean by "really north". I'm a Geordie, so have a slightly different perspective to many when it comes to the definition of "North". But I guess I mean inner northern suburbs. I'm aware of Worthogs, but Greensborough is too far for me. Any venture like this, I would suggest, needs to be well served by public transport, given that it's probably not the kind of thing we'd want to encourage people to drive to.
OK, I'm going to nip around to the Alehouse in the next couple of days and see how they'd feel about a flash-mob of homebrewers ending up at their bar sometime in early January. I will report back to this forum when there is something useful to report.
In the meantime, please keep registering interest.
Also, what kind of club works best? Should it be a formal club, with Chairman, Secretary, Treasurer and a constitution, etc? Or a more informal get-together? (This is all just to stimulate ideas, not pre-empt any meeting). How often should the club meet? Do we want to have competitions, with BJCP judges drinking and scoring our beer? Anyone got any clever ideas for a name?
Hopefully we can keep the momentum going on this and actually organise something which will take on a life of its own.
