I posted a few weeks ago about an Ale that had a lower FG in a bucket than in a Better Bottle. Same yeast, 10G split batch, all things equal. It was chalked up to stratification during the transfer from kettle to fermenter since I filled the bucket first.
Well, it just happened again, this time with a German Lager. I don't remember which I filled first, but now I am wondering if there was more pressure in the headspace of the BB causing it to retain some CO2 and having that effect the hydrometer reading. I did see some bubbles in the BB sample and none at all in the bucket sample.
Thoughts on this?
