As somebody said before, beer is 99% water so the water is an extremely important ingredient. If it tastes good alone it's going to make good beer.
No, that is not totally correct. Whatever water Granite City Brew Pub uses makes the beer taste like crap. When I use my water straight from the faucet, my beer tastes like crap. My water tastes good straight outta the faucet, however, even softened I think alot of iron passes through. I came to that conclusion after drinking at Granite City and comparing notes. My beer after building from RO is exponentially better and now I wanna brew every day. Water has been upped from an 8 to a 10. But if you have rocky mountain water that dreams are made of, run with it.
