Hello,
Some homebrew recipes include adjusting brewing water to 5.5 pH before adding mineral salts and mashing. I am asking those of you that do this, how many hours or days (or immediately) ahead of mashing do you adjust pH?
I use RO water and wonder if my acid addition into brewing water needs a longer time to stabilize than what I typically do.
I add phosphoric acid (the full volume predicted by Bru'n Water to my total volume of mash and batch sparge water, mix with a mash paddle, and separate the sparge volume before mineral additions and heating the mash water.
I use an Apera PH 60 pen meter.
I'm concerned that if there is a lag time in stabilization, the pH reading may be high, resulting in addition of more acid to lower the pH, but result in a too low actual pH during brewing.
To check this, I have incrementally added acid to 5 gallons of RO brewing water, stirred, and took pH readings over a number of hours time before adding more acid, and found that the pH readings increase several tenths of pH and stabilize over several hours. Now I wonder if my pH meter is faulty.
Your comments please. Thanks.
Jeff
