Brewed Sunday night - strong activity Monday morning and was petering out by Tuesday. I was out of town until last night and came home to see the krausen still holding on strong. A good 2+ inches thick. I haven't seen this before.
Brown Ale OG 1.045 - FG 1.01X (can't see through the krausen)
Yeast WyEast 1056
I've only used this yeast once before and I know they talk about it having low flocculation. Would that have relevance to the krausen or is that specific to suspension in the brew? Any way, didn't happen last time I used this yeast, though it was an APA not Brown.
More specifically, the fermentation seems to be finished and the krausen has not subsided. I have not experienced this before and don't know if my brew is telling me something.
Without an accurate reading, it is impossible to tell really. your 1.01x could be 1.019 which I would say you are not done fermenting, or it could be 1.010 which you probably would be. I would give it a few more days, it is probably still fermenting...the krausen should subside.
I just recently encountered the same problem. After 2 weeks there was still Krausen and i was a bit concerned. All other signs of fermentation had subsided. Little airlock activity and just looked done but the krausen was holding on. Took a sample to do a gravity reading using a beer thief. FG was 1.012 so it seemed done to me. The next day the krausen was almost completely gone. Seems like it just needed to be poked at with the beer theif and it happily went away. Maybe my experience will help you some.
same thing here with AAH! (Another Awesome Hefeweizen). The Krausen was just holding on forever. i even rolled the carboy just a tad and it was like a big clump just sitting on top of the wort. it is finally settling today.
Thanks guys. The Gravity is 1.014 after 7 days and still has the krausen. I'm planning not to rack the beer until it does subside even though it is finished.
Deathbrewer or Rick91981 - how long did it take to finally subside? What yeast did you use? Thanks again - always nice to know you aren't the only one.
mine took a total of 10 days it pretty much finished (i thought) after 6 days and then the krausen held for another 4 days without dropping. then it dropped quickly over 2 days. i think it's ready to bottle I'm going to check the gravity right now...
I've racked off to a secondary with a heavy krausen before. Some krausens are literally like sudsy pudding. So heavy in fact that I think there is more yeast sediment above than below.
Once your gravity readings are static for 3 days straight, go ahead and rack to a secondary. Your siphoning tube will stop sucking when that foam descends and hits the end of the cane.
If you like to harvest your yeast, make sure to swirl that krausen into the yeast mix at the bottom.
About 12-14 days it stopped showing major airlock activity. Krausen was still persistent however. A few days later i took a gravity reading. By the next day most of the krausen was gone. I think poking through it with the beer theif may have broken it up or something. Not entirely sure if thats the cause or if it was coincidence, I'm pretty much a newbie.
Krausen Holding On
I'm going to check the gravity right now...
