Brewed a Munich Helles yesterday and fermented it with an ale yeast. OG was 1.040 and it's in my fermentation fridge at 68f. Today when I checked it the lid was domed but the airlock wasn't bubbling. Assuming it was clogged, i,removed, cleaned and replaced it.
After watching for 10 mins and seeing a LOT of krausen coming through the airlock, I switched over to a blow off tube. While there is some obvious activity in the tube, there is still a buildup of krausen and the lid seems still ready to pop.
What's happening? The only way I can get the lid down is to pull the tube and push krausen out through the hole.
