So it looks like I'm going to have to repitch a vial of wyeast London ale after the stout I brewed up never got off the ground. 72 hours of zero activity. Never had to repitch. When you do, is re-aeration advised or does the no splash rule apply?
It would be okay to aerate the wort and repitch if there has been no fermentation. I would recommend making a starter with your yeast though. I like to use this calculator for pitch rate/starter volume.
