Writer's preemptive strke: Yeah, I know you use R/O water and it's a great way to brew, most good brewers do what you're doing. This thread is about DC water, not R/O water.
I've brewed with DC tap for decades. Despite the brain-dead, reflexive jokes, DC tap is amazing brewing water that just needs a bit of acid and calcium to make incredible beer. Since September, I've noticed that my mash and post-mash pH values have been falling rapidly. At first, I figured my calibration fluids had packed it in, so I changed them. Further decreases in my pH were observed. No biggie, I've brewed with DC water for decades...my pH meter bulb must be bad. Nope, new bulb, same values. Then, two weeks ago, I mixed up a new batch of StarSan.
That stuff has been clear for two weeks.
Stuff like that doesn't happen in DC.
Anyone know what's going on?
Yeah, I know you brew with RO, piss off.
