I'm under the impression that's its important to know your water chemistry because it will affect the overall flavor and outcome of your beer. I don't know anything about what I'm looking for in the water report. Can somebody take a look at this and tell me if i need to be concerned. All i could find was the 2008 report, not sure how much water can change in a few years. Also I run my water through a whole house filter if that makes any difference.
