Hi all As you may have seen from my other thread, I have a beer that I have foolishly bottled too early before it had finished fermenting (probably: 1.021 for a kit brown ale). Luckily I went for a low priming value (1.5 volumes) and PET bottles. My FV is now in use for another beer that’s 3 days in - it’s pretty much the same beer (the other half of the kit but with a different DME). There’s a fair amount of headspace (15L FV with 10L of brew). Now, do I try and pour some of the first batch back into the FV and hope it finishes fermenting? Or should I put in into a couple of 5L water bottles I have lying around and let it do a secondary ferment. It would be at ambient temp and I don’t have any spare yeast, except; I could add some krausen from batch 2, or I could culture up some from a bottle conditioned beer. I have a Sierra Nevada that I think uses an attenuating yeast? Or, I could do nothing and hope for the best. The beer is in PET bottles in a cardboard box and will shortly be moved to the shed for a low and slow maturation. Or chuck it. But no one is going to recommend that right? What would you do?
