I've recently moved into fermenting and serving from the same keg. Initially with a bottom tube to harvest and reuse the yeast before drinking. Now I'm using floating dip tubes so I cannot harvest any yeast.
My last couple kegs that kicked I just left them cold in the kegerator. I then brewed up another batch of the same and pitched it into the dirty kegs and let it go again.
What I've noticed both times is that when I opened the kegs, there appeared to be very little yeast cake left compared to what you normally find in the bottom of your fermenter. I assume that when the keg "blew", that last pint took a lot of the yeast cake with it. I pitched around 80' (the limit of my IC and patience) into a 40' keg and stuck it in the ferm chamber at 65'. Both times there was zero observed activity from the blow off tube until 24-48 hours.
Is this time lag due to cold shocked yeast? Should I pull the keg out and let it warm up the yeast cake while I'm brewing?
Is this possibly an under pitch? The "little" yeast cake that was left inside is most all yeast, not trub, since all my wort is filtered from the kettle. Even though it appears minimal, it should enough to get started?
