Need some advice, I brewed a Maibock 96 hours ago, I pitched a 2 liter starter of WLP833 on a stir plate at 72 degrees into a 1.060 wort at 72 degrees as well. I dropped the temp to 55 over a 24 hour period in my fermenting fridge. I've agitated the wort again but no change at all. The only back up yeast I have is Safale us 05. Should I wait another day to pitch in the ale yeast or wait it out? I don't have a LHBS so just going and buying another vile is out of the question. Please help!!!
