Wild bugs & pH probe?
« on: December 23, 2011, 09:54:21 AM »
I'm a wild brew light weight, but I'm realizing I'm brewing more and more of them. My
question is do the brewers who manage their pH, have a wild bug dedicated pH probe?
Given the contact time and then I Starsan it; what are the risk? I cleaned and
recalibrated the probe after the Starsan routine. Will the bugs persevere?

You shouldn't test the whole batch post-boil. Always draw a sample and test that. Do the same for the mash and let it cool first.

My last probe was infected with something and I soaked it and the cap in Everclear for a few minutes. Seemed to help a great deal.

From what part of my question did you glean I test the pH hot? I made an aluminum and copper sample chiller and test at 21 c, since my pH meter has a temp prob. I do like the Everclear idea; my probe will be getting the acid alcohol treatment next time.

Whether you're testing gravity, pH, or something else, I would throw out (i.e. throw down your throat) samples instead of putting them back in your fermenter.  This prevents contamination.
