I brewed a SNPA clone two weeks ago and it still has a full head of krausen, I pitched at 72, it started up pretty typical, it’s been hovering between 64 and 68 in my cold basement. Bubbles slowed down after a few days, but it’s still slowly chugging.
I’ve never had this happen before, not sure what to do? Heck the beer is even clearing up quite nicely.
I have had it also. First I thought it was an infection because I got my hand in the wort before pitching. It was one of those brews where a cascade of stupid things happened. I asked the same question in the Norwegian hb forum, and the answers where that it happened from time to time. The beer, a pale ale with 25 % rye and a healthy doze of Willamette turned out to be the best session beer I’ve ever made. It was nice and clear under the yeast cake. As I did not want to serve this “hand crafted” beer to anyone else, I finished it myself. Took one for the lads. Taste a sample. That will probably set you at ease. It was US-05
Agree with James. Raise the temperature and that will help it finish. I have done this by raising the temperature to around 70 degrees or so and the beer finishes.
I can almost guarantee that your beer has completed fermentation. Probably finished within the first four days.
In those instances where the krausen has stuck around (especially with US-O5) I would typically rack from underneath the krausen and package as you normally would.
My guess is the higher % of proteins from the considerable amount of rye that you used is leading to the “sticky” krausen. Be sure to take a gravity reading prior to packaging just to be sure your beer has properly attenuated.
THIS. Everyone is telling you how to finish fermentation but it’s likely already done. Bubnnles don’t tell you whether or not it’s done. Take a gravity reading.
As mentioned, FG has likely been reached unless there was a fermentation problem. I cold crash to remove any remaining krausen. Don’t know if you have the ability…
Sorry, I am going to go against everyone’s advice here. Your beer is ruined! You need to ship it to me immediately for safe and authorized disposal as this will require a very steady hand. I’m the only one who can do this for you. Trust me. Don’t question it.
Cold crash! Cold crash! Cold crash! I agree. It’s probably done. See if the Krausen sinks when you cold crash. If not, do what was mentioned and rack below the krausen.
I have a beer with small bubbles in it right now, about a month old, but I think that’s the Brett. Gravity on that is .995.
What are you fermenting in? it sounds like glass because you say it’s clearning up. If you can’t read gravity you’re probably fine anyways, but I would still raise the temp for a day or two.
You pitched kinda at a high temp. But overall I think you’re fine. Us-05 tends to rip through my beers
Shake it up gently, then cold crash. I asked on this forum once about a persistent layer of “gooey” krausen and was told it was a “pancake”. It was held in place by sticking to the edges of the carboy and then sticking to itself all the way across. Once I agitated it enough to break it loose from the walls, it separated into rafts and they sank readily.
I had a spigot on the bucket, and just bottled from beneath the land rise of 05. As mentioned, others had seen the same with this yeast. The beer beneath was actually very clear.
I took a gravity sample and within minutes all the krausen dropped. Gravity was right where I expected it to be, racked to secondary. Sample tasted good.
