Ph raises to nearly neutral during boils

[Vezza]

Hi all, I’ve been following this page for awhile and now look foward to being an active member. I’ve been searching for an answer on this for some time with no success. My acidic water is ph’d to 3.5-4 before going into the powdered bark put rises to nearly neutral during simmering. I was wondering can anyone tell me if this is ok or should my boil be at a ph of 4. I get ok yields but am always looking for ways to modify my Teks to make them more efficient. Thank you in advance for any help

The inverse should be true, PH Should lower during boil

What I’m seeing is rather odd then. I’ll have to do some more research as to why this is happening I have just assumed it was the ph of the bark raising the ph of the water up until now. Thanks for clearing that one up for me simple_me

It depends how acidic the water was to start with, and the amount and type of other dissolved material, as well as the bark itself.

This raising of the pH could be taken as a good sign. Those protons have got to go somewhere...

For all I can remember MHRB has an own ph of around 8.

How do you acidify the water? If for example, you are using very little vinegar to get to a pH pf 4 what you are seeing makes sense I think.

How do you measure the PH?

With papers or a probe?
