Having what I perceive as an odd issue lately. The beer:
Dark mild at 12P
KO ph cooled in to 67f at 5.1 (slightly low but meh)
24 hours in 9P and 4.4ph (seems like a huge drop)
48 hours in 4.3P and 3.95ph - way low, tastes tart
Yeast is wyeast 1318 gen 3. Cell count showed .8bil cells/ml with 96% viability so 35.2lbs of slurry was pitched into ~ 8bbls of wort. I've had this issue happen with other beers and although the ph seems low at this point (not quite ever 3.95) the beer always finishes up and seems to correct itself to 4.25-4.35 range generally.
My first thought is that my cell counts are drastically off (given how many pounds of slurry I'm pitching it sure as hell seems like way too much) and that I'm overpitching - would that cause this ph issue? In my defense, I've counted other strains like Conan or Chico and have gotten the normal densities you'd expect to see (1.5-2bil cells/ml) and this 1318 strain from 2 different suppliers always seems to have the same low cell count upon harvesting.
I've learned not to freak out until it's time to in this business, but I'd like to understand what might be happening and how to resolve this issue. I've also had this happen with wlp007 and a Conan variant.
Any ideas?
