Hello all, Im new to water adjustment and I recently had a RO system installed and sent a sample to Ward labs for analysis. I've been playing around with Bru'n water and this is what I've come up with. How does the PH and water adjustments looks for a Kolsch beer. From what I've read, the PH should be between 5.2 and 5.3. Also, should similar mineral additions be added to the sparge water? I see the spreadsheet puts them at nearly the same. Thanks for any help.
