One of my kegs of low-O2 beer went down earlier this week and I just replaced it with the summer pale ale which finished carbing today (that's 16 days grain-to-glass on that beer). When I disconnected the empty keg there was a thick blob of yeast on the post. I switched the kegs, changed the tap handle, etc. and there was this great aroma from the yeast on my hands and I realized it smelled so great because it's 2124. Then I realized that there must be a bunch of it at the bottom of that empty keg. And there was! I sanitized my funnel and flask, tipped the keg upside and got about 400ml of fresh yeast. I feel like I could just pitch it but maybe I should make a starter with it. Has anyone ever harvested yeast from the bottom of a keg before? I typically wouldn't have that much yeast in a keg but the low-O2 processes are weird like that. Any thoughts?
I think I'll do this with it:
