Krausen plugged neck of carboy during active fermentation. ?!!?
And I had no idea until last night. I took carboy out of cooler, popped the cap to do a gravity read and krausen had plugged the damn neck of the carboy !!!! I stuck the hydrometer thru it, and the plug fell back in the beer.
I boiled this batch on Sunday, and the airlock was bubbling fine until Tuesday, For all I know it got clogged on Tuesday when airlock activity stopped?? I even ran a second tube to prevent this, but that plug even trapped the airline tubing hose......
Could this be a problem?
