Just tested the PH on an ordinary bitter mash. Mash tested at 5.4 at 66F. Not that I'm real worried about it but Bruunwater estimated my mash PH at 5.2. I am planning on doing at least one batch of BoPils this summer and would like to be able to hit a low mash PH. I seem to consistently run .2 high. I have a recent Ward labs water test and I use a Hanna PH meter that was calibrated this morning. Any thoughts?
