no the homebrew tap would be a variable as and when available, special thing , ( in the same way as the casks in the B&C go down so well ) marking out the bar for a bit of uniqueness .
They would then of course have a selection of other quality consistently produced beers available . I'm not suggesting any homebrewer would make a sole living out of this , but it could encourage diversity in the market if it were allowed, and would provide a more professional avenue and stepping stone to those considering making the leap from homebrew to microbrew ( which at present is an astronomical leap )
I'll put up me money there some day next week and discuss this in Beoir ...
