Fermentation query
I put a brew on the other day and I'm just wondering whether the sudden drop in temperature may have stalled the fermentation.
I've attached a link to a photo below and you can see there's what appears to be particles of dried yeast floating on the top.
I don't recall this happening when I've done brews in the past, so can anyone advise please whether the fermentation might have stalled and if so, then what I can do to get it restarted?
Cheers.

Re: Fermentation query
check the gravity.
Then again after another couple of days.
That should tell you the answer.
Also you've not said how long it's been fermenting. Most ales will ferment out within a few days. Lagers will take longer (typically).
This assumes a typical ale fermentation temperature of close to 20C

Fermenting: Geuze, English bitter
Conditioning: English IPA/Bretted English IPA
Drinking: pseudo “beyond the Firs” (Burnt mill beer clone), Sunshine Marmalade, Festbier, Helles Bock, Smokey lagery beer, Irish Export Stout, Orval clone, Impy stout, Duvel clone, Conestoga (American Barley wine), Dobbin 2 dark mild
Planning: Kozel dark (ish), Simmonds Bitter, Citra PA and more!

Re: Fermentation query
Thanks Cobnut. I brewed it on Tues, so maybe I'm being a bit impatient. I'll keep an eye on it over the weekend and take a couple of separate gravity readings.Cobnut wrote: ↑Fri Jun 18, 2021 12:49 pmcheck the gravity.

Re: Fermentation query
adamz,
If that was my beer I would get a sterilised spoon and push those floaty bits down,
then give a good stir and do as cob said.

Re: Fermentation query
+1 Don't bother leaving it a couple of days--just increases the chance of infection.
Give it a really good stir and see if it wakes it up.

Re: Fermentation query
Cheers chaps. I'm away camping this weekend but as soon as I get home I'll give it a good old stir!
Re: Fermentation query
I very much doubt the temp drop was enough to stall it.adamzworld wrote: ↑Fri Jun 18, 2021 11:53 amI put a brew on the other day and I'm just wondering whether the sudden drop in temperature may have stalled the fermentation.
Do you KNOW you have an issue or is this just a unsubstantiated thought? (we all get them).
Test the SG. It's probably done.

Re: Fermentation query
What size batch? How much of a temperature drop was there, and for how long?
I'm just here for the beer.

Re: Fermentation query
You could well be right that it's an unsubstantiated thought. I haven't done any brewing for a few years, so may be being a bit paranoid.MashBag wrote: ↑Sat Jun 19, 2021 8:17 amI very much doubt the temp drop was enough to stall it.adamzworld wrote: ↑Fri Jun 18, 2021 11:53 amI put a brew on the other day and I'm just wondering whether the sudden drop in temperature may have stalled the fermentation.

The ambient temp was a around 25oC on the day I put the brew on and has now dropped by about 10oC.
I've given it a good stir, so hopefully that will wake it up. I'll also take a gravity reading in a couple of days to see if it's made a difference.

Where is it? In the garage?

Re: Fermentation query
Absolutely.
Tbh the best thing you can do for your beer is to get the temp stable for primary fermentation and it doesn't have to cost a fortune or take up space.
Happy yeasties make best beer.

Re: Fermentation query
Took a gravity reading tonight and although I didn't take one last week, it looks like it's almost done. I also tasted the sample jar and it didn't taste too bad considering it's only been in the FV for six days. I think I'll chuck the dried hops in tomorrow evening and then transfer it to my pressure barrel at the weekend.

Re: Fermentation query
Good news.
For most beers of the fermentation is over in the first 3 - 4 days of its at a steady 20c.
Consider a heat mat and an inkbird - your yeasties will thank you
