Brewed a big beer yesterday, 1.070. Kept the keggle in the garage covered due to frozen water spigots so no immersion chiller. We had started the us-05 rehydration that afternoon due to our expected finish time (oops). Aerated the wort with a drill and sterilized paint stir, pitched 1.5 packets of the rehydrated us-05 per 5 gal which the wort was at 54 degrees, took in to a cozy spot in the basement where it sits at 64 degrees. 36 hours later, no activity. Repitch tomorrow morning when the store opens? And is this a lost brew?
