Wlp802 went fast
wort-h.o.g.:
So I pitched my 1gal starter of wlp802 ( .5 gal stepped to another .5 gal...estimated at 500 bill cells) into my pilsner at 1.051OG. I pitched decanted starter into 60f wort and It started fermenting after 6 hours, and now at about 81 hours of fermentation, it's at 1.020. I'm thinking tomorrow night I better do the d-rest, as at 1.019 I'm at about 80% complete since my final should be about 1.010. My fermentation temp has been 51-52f. This just seems really fast to me...but I've never used this yeast before. Ay thoughts?
BrewQwest:
First off....pitching your gallon starter is not really what you did...you made two of the one-half gallon starters which is not the same at all... did you use a stir plate? did you aerate with an aquarium pump? did you use oxygen? forgive me if I do not know your past posts, but many people coming to this forum would not know either unless you specified with more information......IMHO, your fermentation stage is only 61% completed from what you described so why would you want to do the D-rest this early? my math may be wrong and if so I apologize...cheers!!-

Looking at Mr. Malty and Yeastcalc, you needed 375 Billion cells if that was a 5.25G batch. If you pitched 500B, then that speed would not surprise me. That being the case, take a taste and see whether you need a diacetyl rest at all. You pitched plenty of yeast and sounds like they were quite healthy!

dave- thanks for the constructive feedback. my fault for not saying, but i was 5.75 gallons in the carboy. mr.malty and other calcs called for about 410bil, so you are correct stating i pitched a little high (by design).
i was just surprised how quickly its moved. im targeting around 1.016-.017 to do the d-rest...i just prefer to do it as matter of practice vs. skipping it and getting burned by the butter...so to speak. ;D
thanks again for the feedback.
