Since I have some mates that live in Condos where gas is not an option due to fire concerns, and they do not have much room, I thought something like this would be great in big cities.
Hopefully a place like this would let you follow your own recipe though.
This concept is pretty popular in Canada, where it's commonly known as Brew on Premise (or BoP.)
Due to high taxes on beer in Canada, homebrewing and BoPs have bigger economic advantages than in many other places.
As I recall, the price of brewing at them works out to somewhere in between home-brewing and buying craft beer (roughly C$60 for a 23L batch.)
I've never tried brewing at a BoP myself, but I've thought about working at one if/when I move back to Canada. Lots of fancy homebrewing equipment to play with and (I'm imagining) not QUITE as much stress as working in an actual brewery :)
Probably no problem with any laws. There used to be a BOP in Henderson in Auckland. I'm talking '95ish. I think the key was that the punter had to do the actual brewing him or her self so that it qualified as beer brewed for self consumption.
Yep, it was a "UBREW" which, I think, was part of a franchise which never took off. The owners slapped a bit of a "Jake the Muss" pub on the front, and sold their own brews. It was extract only. Alex and I went over to look at the possibility of buying it at one point, as it was going for a ridiculously cheap price, but unfortunately, being extract only, and requiring a truckload of maintenance/renovation to get what we wanted, we decided it wouldn't be a great idea. It then became Waipa Brewing... not sure what happened to them, though I've heard many a rumour.
