Is there any concern about oxygenating the beer when you reattach an empty jar and open the butterfly valve? In my head it seems like air would pull in through the top as the wort/beer drops into the jar, and maybe some air travels up through the beer from the empty jar?

Paul Oster

C02 is heavier than air, so it (the air) will immediately rise though the wort, and through the c02 gas layer on the top and get purged in by bubbler. Yes, you will introduce oxygen, but it won't last more than maybe an hour or so before it all gets pushed out by the heavier CO2 (assuming you have a yeast reaction active in the fermenter)

If you do this when theres a little yeast left the oxygen will get purged with the last few days of fermentation

Been using this system for a couple years. Absolutely love this setup!!!!

When capturing the yeast from the catalyst, is that for beer only or can you do the same for wine making? Respectfully submitted.

When dry hopping is it best to wait until fermentation is complete? or during fermenation? and for how many days do you leave the hops in the fermentor?

Would love to see a smaller version of this like a 2.5 or 3 gallon version would hit the spot

Does the system work the same for wine yeast as it is caught for beer? Can the wine yeast be reused as a yeast starter for wine?

I've never dumped the first trub... I poured the wort, added the yeast, attached the blow over hose and it's been sitting for 8 days so far.

If I dump the trub now, I'll lose some if the fallen yeast... does this matter?

Or should I just wait away this point and dump it all on day 14?

You should wait about 8-10 days for the initial trub dump, this will give your trub time to settle out and compact in the jar. Anything collected after this dump should be clean yeast suitable for repitching in your next batch. Cheers!

Can’t wait for the two I bought to arrive.

What is the recommended method of dry hopping?

CraftaBrew

7y↑3

We recommend using a nylon or muslin bag for dry hopping, this will ensure the jar does not fill up too quickly. We have found that hops do not settle and compact as well as other trub material in the jar.

how long did you have it sit during pre fermentation?
what did you have in for pre fermentation? was there hops used during then?
what kind of sanitizer do you use?

CraftaBrew

The pre fermentation stage is optional but we let it sit for about 2 hours before pitching the yeast. No hops were added during this time but the pre fermentation will allow some of the trub to settle out and be discarded before proceeding to fermentation. We use Starsan which is a great sanitizer that can be put in a spray bottle for easy sanitizing without wasting extra water.

We waited around 2 hours to allow the hops and other solids to settle out which is what we called the "pre fermentation" step, this just allows some removal of trub before fermentation. During this step there were hops and other solids removed but nothing was added during this time. We use Starsan sanitizer which is a great all purpose sanitizer, having a spray bottle of it handy makes sanitizing quick and easy.

Looks like a solid product

you show setteling & removal of first trub after "pre-fermentation" - is there a timeframe on this?

@Tylor Miranda How many hours, or minutes do you think it’ll take for it to visibly settle, or (clear up?) Thanks! 🙂🤙🏼

James L

How long for prefermentation stage?

Bernardo Lobo

So beautiful! :')

Saiyant Nick

Just ordered one!! I cant wait for it!

The difficult part of the process is lifting the 50 lbs of wort and fermenter to the counter top.

CraftaBrew

The fermenter is on a counter for demonstration purposes and does not need to be elevated. We recommend a closet, kitchen, pantry etc.

The video shows bottling after 16 days of fermenting. I just want to make sure I am understand that correctly. Thanks!

That depends on the beer recipe you're following.

Will you guys/girls ever make a bigger version

Is there a Belgium Quad kit about 9.5 to 11.5 ABV?

CraftaBrew

We do not have a Quad but we do have a great Dubbel https://craftabrew.com/collections/5-gallon-recipe-kits/products/belgian-abbey-dubbel-5-gallon You can use any recipe you want in The Catalyst so if you find another recipe supplier feel free to order and brew your Quad from them and ferment in The Catalyst. Cheers!
