I pitched the first pack with no starter into some 1.069 wort at about 85 degrees and after the first 12 hours it had shown no signs of fermentation. I pitched the second pack just to be safe at the 12 hour mark and checked gravity at 24 hrs. No indication of fermentation. At hour 30 this yeast began to do its work and now at hour 40 it's going strong, full krausen. After reading this thread I expected to see signs much sooner, and even thought I may have missed it, hence the gravity reading. At this point I think the age of yeast and most probable cause was the health of the yeast culture prior to my purchase. As my first brew with Kveik I may have expectations a little too high but lesson has been learned. A fresh pack of Hothead is en route now for my next brew.I picked up a few packs for Bootleg Biology Aurora from my LHBS that were on sale due to the date of 12/19/19. After reading most of this thread it seems like I can avoid making a starter and just pitch the whole back with no issues due to the small amount of yeast needed for fermentation. Even if there has been some yeast die off since it was packaged its probably more than enough to have a successful fermentation.
