For my upcoming PM batch, the Brunwater spreadsheet recommended no acid additions inorder to achieve a 5.4 mash PH. This got me intrigued because the grain bill is mostly pilsner with only a little bit of the darker grains - usually some acid is recommended for my water.
So, out of interest I removed ALL the grains from the spreadsheet and ALL the mineral additions and the value for "estimated room temperature mash PH" was 5.8! With nothing added, shouldn't this value be just the untreated water PH?
Water Profile:
Ca 11
Mg 1
Na 7
Cl 9
SO4 12
HCO3 25
PH 8.4
Grain Bill (PM):
Pilsner 4lb
White wheat 7oz
Flaked wheat 7oz
Aromatic 7oz
