Aug 16, 2018 at 23:10 comment added FredrikH-R Then I guess I might be a master aireator ;) thanks for the clarification though. Care to work it into your answer?
Aug 16, 2018 at 23:08 comment added Evil Zymurgist @DJHellduck it's usually not an issue because it's pretty hard to over oxigenate. But yeasts trigger to stop lag / growth is when oxygen is depleted.
Aug 16, 2018 at 22:50 comment added FredrikH-R We aireated thouroughly both the beer and the yeast - the starter might even have been shaken extra for the stalled one, so this could actually be a possible difference. To be honest, I wasn’t aware that you could over-aireate your wort, and all the resources I’ve read emphasize as much aireation as possible... All truths are with modifications I guess, but why would too much oxygen be a problem for fermentation?
Aug 16, 2018 at 22:38 comment added Evil Zymurgist @DJHellduck the only other thing I could think of is that the flat liner got way more oxygen and the yeast took longer in a growth phase. The tell would be more trub compared to the other fermentor when done.
Aug 16, 2018 at 22:32 comment added FredrikH-R Thanks for answering. We alternated filling the buckets, and also alternated pouring in the yeast. Of course, there might be differences, but I don’t really believe it is enough to completely stall one of them...
