So our two day kettle sour brew went off without a hitch. Sadly, the pH meter we had didn't work, and the new one didn't get there until the second day. Day one took about 4 hours, and then 2 hours on day two. Not too bad. It's going to end up as a blueberry berliner.
@gee or any of you other folks: We have a Milwaukee MW101 pH meter that is possibly about 8-10 years old. Since we just started using it, I just got a new electrode for it. The thing is backwards. When I dial in the 7.0 buffer solution, the 4.01 buffer reads as a pH of 10. So it's opposite. Milwaukee had a chat support on their site and the dude said since I replaced the electrode, the base unit must be bad. That seems odd.
Any ideas?
