Hey everyone, In the picture, take note of the 2 back carboys. One is clearly differentthan the other in terms of fermentation process. Both were same boil, same US-05 pitched from same starter (divided). Temperature difference over each side was less than a degree ( cold air source is on right ). I'm not yet concerned at all, letting them hang out for another couple days before FG and crashing, but ever so curious as to why a difference? Yeast was well stirred and I am fairly confident the pitch was equal between both carboys. Perhaps one had more trub from BK? Even if it did, shouldn't matter much. No big deal probably, more an observation worth discussing.
