New layer of froth

[rg013]

Hi,

My latest brew was bubbling along as usual, went through the froth on the top stage then cleared as usual, all the time the airlock was bubbling.

Then overnight another layer of froth had formed on the top of the brew. Its still kind of bubbling but I haven't experienced the second froth stage before. Usually the brew clears and stays that way.

Can anyone give me some idea of what I am experiencing?

Thanks,

Relative newbie

Fairly new at this myself, haven't heard of it before either.
Unless the yeast had started to become dormant and a warm night fired them back up?
I'll handball this on....

it's probably nothing, just the yeast being funny, hows the airlock smell?

Airlock smell is unusually fruity, no off smells. Its a Coopers Pilsener mix, with a HBS Megabooster Sugar/Light malt mix, plus 200g of dextrose added, and using the american ale 56 yeast also from HBS. Was pitched at about 24 degrees. Was slow to start as temp went to about 22 dgrees overnight on the first night but came good. Frothed up, bubbled away then cleared with good airlock bubbling. Initial reading was 1060. Then froth returned,

Thanks for your help,

Have you stirred up the yeast cake or changed the temperature of the fermenter.

I sometimes get a renewed krausen after racking or if I turn the fermenter fridge temp up to make sure the batch is finished

Cheers

The temp changed as a result of the atmospheric temperature, went down a few degrees over night but didn't get below 21 or 22. I haven't stirred anything up and the fermenter has been still.
