Open/Double Fermentation
« on: January 18, 2022, 08:04:03 am »
Purchased 7.9 gallon ferment bucket, batches brewed are 4.5 to 5 gallons.
Next batch will be first open ferment, and hopefully
first yeast capture.  Any advice, stories and articles are welcomed
,as I explore this new to me method.

We've talked about this on the podcast a few times.  Keep it loosely covered with foil til you get krausen. Remove it once krausen forms. Cover it again when krausen drops.

This was my Ringwood (WLP005) fermentation.  Finished with high attenuation and no diacetyl:

Thanks
My bad, should have been more specific, aware of that process, thanks.
The process starts as you stated, then transferred to a secondary fermenter during peak fermentation.

Nice pic

Did you scoop off brown crust, harvested yeast,
then transferred to a secondary ?

Thanks

Next batch will be Open/Double fermentation.
Never made a starter, will use 1469, and a 1000ml fast pitch starter kit.

Bottle carbonation is perfect, not removing krausen.
Current thought is the krausen that normally
falls back in the beer, aids carbonation.

If krausen is removed, will this increase the amount of
cane sugar that should be used for bottle carbing ?

Thanks

I'd it aids in fermentation,  it is just because it is more fresh, healthy yeast and not because it is providing unfermented extract. The amount of priming sugar required would be the same. If there is any change in bottle fermentation (and I honestly don't believe there will), it would be in how fast refermentation and carbonation are completed.

It did look like some kind of extruded breakfast cereal.  Definitely one of the most unique fermentations I've had.
