What's the collective noun for homebrewers?

Last week was the second Australian National Homebrewing Conference in Melbourne and on Thursday afternoon (and well into the evening!), the St Kilda Taphouse were lucky enough to host one of their social gatherings. I'm not sure what the collective noun is for homebrewers but please post any suggestions you have below.
