No such thing as too many taps. As well as being a home brewer, I also bar manage for a couple of bars. We are opening a new one and plan to have 50 beers on tap. Having 32 taps in one of our current locations, I know how much wall space is consumed. I didn't know if anyone out there has ever seen stacked taps. This way we might be able to get 2 rows of 25 and cut the length in half. however, I have never seen staked taps and am not sure how do-able, or efficient it would be. Anyone out there have any suggestions?
