Hi all, my brother was asking me PH questions, and I realize I am fuzzy about certain things. So I have a few questions to help those of us who never really thought about PH in a practical sense:
1. Time
How long should I wait before taking a reading? Right after mashing-in, 10 min into mash, or 30 min?
2. Sample "location"
Where is the best spot to take sample from? Scoop out from the top? From the spigot?
3. Sample purity
How much grain/husk is acceptable in the sample?
4. Temperature
Room Temp? Mash Temp? Same temp as calibration solution?
(I understand room temp is best because it's better for the longevity of electrode and (even if I have ATC) the mash ph changes with temperature
5. Adjustments
Am I mostly looking to adjust for next time I brew this beer, or now?
(If now, after 30 min have gone by, what is the purpose? Conversion has already happened, no?)
Please feel free to add any other questions or comments, I'm looking to create a nice little cheat sheet for my brother while I re-read all Adjelandge's posts and finish the water book.
cheers
