Double Fermentation

[Adam P]

I was wondering if anyone knew anything about double fermentation. ie If I put one brew on, wait til its fermented then put in exactly same ingredients to brew with another yeast packet? What is it called and does anyone know of the results???

little bit unsure on what you mean mate,

Do you mean brewing 2 indenticaly made beers with different yeast ? or do you mean adding more unfermented beer to fermented beer ?

Completely lst me, as well. :blink:

Aaron, I have a nasty feeling in my gut he means the second scenario you mentioned...

You can:

1. brew, ferment, bottle/keg then brew again with the same or different ingredients using the cake or slurry from the first brew. There are different methods used, this is quite common. Results are as good as your processes.

2. brew, ferment, brew and ferment again with same ingredients (or slightly altered or different but complementary) then blend. This is quite common and again - results are as good as your processes and the sensible matching of your recipes.

3. Brew, start fermenting, then brew with the same ingredients (minus yeast) and add the first lot to the currently fermenting beer. I'm not sure how common this is but my understanding is that some trappists do this to allow the yeast time to build up cell counts and not get stressed from eventual high gravity beers. I've done a similar thing once - worked ok, beer wasn't the best (wasn't awful either) but neither was the recipe so I'm fairly certain that doing it was not responsible.

If it's something else you have in mind then I'm not sure. I wouldn't ferment right out then brew on top of that with fresh yeast but I'm not going to state outright that it's wrong - it just doesn't make sense to me.

hey hey,

If your brewing the exact same batch might aswell do a double batch ie 46 litres so everything is on the exact same page and will save you time of doing two brews and adding an unfermented brew to a fermented brew. Im not quiet sure why you would want to put an unfermented brew onto a fermented brew as I dunno how it would taste in the end or what it would achieve but it's up to you if you wnt to experiment and let us know how it goes.

still talking in circles mate.
Generally talking a double batch is 40 L plus.
Ferment first one the bottle or keg.
Through the second lot onto yeast cake and go again.

Unless you have exact scenarion of yeast count and initila fermentation you will not have the same result.
That goes with temperature as well.

Am I barking up the wrong tree Dickman.

Pleeas be more specific... :huh:

It depends if he is talking double batches by dumpingf a new batch on the old or dumping a new batch onto the old yeast cake. Either way the brew will share similaraties but wont be the same. Adam would you care to shed some light ona few more details for us?

considering no response, i'd say the OP has left the building. reading his post it sounds like he is wanting to brew a batch then clone the same batch sepearatly.
e.g. "then put in exactly same ingredients to brew with another yeast packet?" E.g. another batch?!?!

Ok, so we wait.....
