Ok so I am a special kind of stupid. For the first time I have 3 beers fermenting and apparently that’s to many to keep up with. I brewed an barleywine yesterday and I thought to hit it with some extra oxygen. Problem is I messed up and added oxygen to my strong ale that is at day 3 and the Krausen has fallen. Obviously fermentation isn’t 100% complete, but how bad did I just screw up this beer? And is there anything that can be done to mitigate the side effects? Thanks all!
