Interesting. I have been using Cincinnati tap water for wine since 2006 and either have grown accustomed to or can’t tell by taste but I think my water is fine. Even bottled water still could contain chemicals the same as tap depending on what type of filtration is used.
Anyway I found this on the GCWW website
Is it safe to drink tap water in Cincinnati?
Very safe. Cincinnati water is very good. The local home beer brewers send water sample out for professional lab testing. The results always come back excellent. Cincinnati water is moderately ``hard'' meaning it has a bit of calcium in it. It is a little hard on faucets but healthy.
