I just realized that I totally screwed up the water chemistry on my last brew. I was in a hurry and plugged in some wrong numbers on Palmer's spread sheet.
Bottom line is that I was making a Czech Pils, shooting for a Residual Alkanlinity around -60 and ended up adding WAY TOO MUCH CaCO3 and the RA was 193.
Just a little off, right? It's been fermenting for a week and I just realized the mistake. I haven't tasted it yet, but I know it's going to be the most harsh, bitter taste ever. Correct?
Anything I can do to fix this now? Even if it means diluting the batch a bit? I know the first step will be to taste it, but I know what to expect. First big brewing screw up in a long time. Thoughts?
