My notes show that I should have a mash pH between 5.1 and 5.5 at mash temp.
But, due to using a pH meter that is ATC (automatic temp correcting) that I need to subtract .3 from my readings to get to the mash temp readings. So a reading of 5.7 on my meter would be 5.4 at mash temp.
Is this correct?
I don't remember where I got those notes.
What should my mash pH reading (range) be on my ATC meter?
