Krausen Not Dropping When using Yeast Nutrient

[Colorado_Wanna_Be_Brewer]

Hi All,

In my last few batches, the Krausen has not been dropping after 3+ weeks. I have been using the Wyeast Yeast Nutrient (although I have used it for some time and never come across this problem). I dont want to touch the Krausen or disturb it to get a gravity reading. Eventually on the last 2 batches I just racked with the Krausen still present (after like 25 days) and the batches came out fine.

Just wondering if this is a common problem with yeast nutrients or if it could be something else.

Thanks!

Could this have anything to do with the water?

Same recipes each time? When I brew wheat beers the krausen doesn't fall.

are you using US-05 ?

are you using US-05 ?

I am using US-05 on this batch (actually 2 5 gallon batches having the same problem) but the previous two were WLP001 & 1056 and I had the same problem.

Is this common for US-05?

The recipes were different for all of them.

I have come across a little bit of information on this board about the Wyeast Nutrient possibly causing the Krausen to get stuck at the top but I'm not sure.

Just wondering if I should give them a shake and see if the krausen falls to the bottom?

I can't remember using yeast nutrient in any of my brews (about 30 so far). I also prefer dry yeast, and US 05 is my go to. Never had krausen not drop. I would suspect the nutrient, try again without it. I rehydrate the dry yeast for about an hour, and usually have activity in 4-6 hours.

I've had that problem before with the Chico strain I was probably using yeast nutrient at the time. Chico usually takes about 2 weeks to flocc out for me as compared to three or for days for the British strains. Haven't had the problem with nutrient and the British strains.

I use yeast nutrient every batch and haven't had this problem. The last batch with Burton yeast was slow to drop but as soon as I added beerbrite it clear within a day

Wait, you added beerbrite to your beer?

 

[Queequeg]

Yeah, its freeze dried instant isinglass. I have only used it the once but it works pretty good.

 

[wdprice3]

Ah, ok. When I hear beerbrite, I think of the cleanser/sanitizer.

If you have hit your FG, you can always cold crash to get the yeast to drop out. Either use a fridge or put your beer in an ice bath.

Other than yeasty beer, what is the big concern about the Krausen?
