Fermenting over but still a huge krausen

Post by barry44 » Wed Dec 17, 2014 12:16 pm

Hi guys,

I made a big beer a couple of weeks ago, SG 1.067 and have been checking on it over the last couple of days.

Last night would have been my usual time to transfer to secondary and dry hop but i am concerned that i still have a massive krausen on the brew.

The FG was at the Beersmith estimation last night, i had checked it on Sunday and noticed it had dropped a little between Sunday and Tuesday but i never managed to check it on Monday.

If i check tonight and the gravity is the same but the krausen is there will i be ok to transfer it to dry hop it?

Alternatively, i could dry hop in my primary but i am looking to heave in 150g of simcoe leaf and was hoping that the stirring effects of the syphon would help the hops get wet.

I was considering rinsing my yeast after transferring but this is not a necessity as it is US-05 ive used and not a liquid strain.

What's your thoughts?

I've had US-05 form a 'crust' before and it was fine.

If its not producing CO2 and your hydo readings are stable I wouldn't worry. I've had a few ales still with a bit of a krausen floating around after fermentation is complete. Just taste it also to make sure it's not due to an infection (unlikely).

Rick, i don't use an airlock as I have the coopers fermenter so I'm unsure if it is producing CO2. Is there anyway I could check that?

Why wouldn't you harvest us05?

Kev,

No real reason.

My 2 cents:

-crop yeast off
-dry hop in primary

you might not want to rebrew with the yeast since you had a biggish beer (a lot of poeple recommend repitching with yeast below OG of 1.060 because fermenting out a beer above that level will use up the yeast's reserves), but you don't really want all that yeast in there when you dry hop.

if you are using whole cones to dry hop you could consider blending them into a paste or suspending them in a hop bag in the beer - like you i find whole flowers float on surface of beer, which means you get little aroma out of it into the beer.

If its finished it shouldn't be, but you will see small bubbles rising to the surface - this is what forms the krausen when its fermenting.

Still fermenting, down a point from last night according to the refractometer

If it's finished and there's still a crust then you can just skim it, some people don't bother though, I skim just before crash cooling as I believe it helps with clarity and possibly flavour as that bitter tasting yeast will otherwise be floating down through the beer until it's settled.

That's a good tip. Thanks for that
