The Catalyst Fermentation System: A Hands-On Review

[@MrSindicatedSyn]

Because of the size and location of the mason jar I was able to place a cheap magnetic stir plate underneath. It did amazingly well keeping the yeast in suspension during primary and fermentation was stead throughout. Also if you connect a shutoff valve to the hose you can eliminate the mason jar after primary and just use the bottling attachment for draining. You can then remove future sediment without introducing additional oxygen. Love the Catalyst system. Lots of options I didn’t see anyone else mention or attempt yet.

[@BEERNBBQBYLARRY]

Good idea as long as it the trub isn't stuck in place and refuses to drain. That is a common problem with some other plastic conical fermenters with small dump valves which is why the Catalyst stands out with its large butterfly valve.

[@ronaldsorensen1330]

You avoid aeration when replacing the jar by installing the sample tap. With the tap you can fill the jar with wort prior to reattaching. With the jar full, when you open the valve you’ll get minimal air entering the system.

[@codebowl]

Great tip, thank you!

[@killswitchh]

This is what i'm running into. I'm not quite sure by what you mean. What sampling tap do you use?

[@bradhopkins2248]

@@killswitchh CAB now sells a separate tap you can install onto the fermenter by drilling a hole for it.

[@flyingbatfish]

Thanks for taking the time to make these videos. Early in my home brewing "career", I had an airlock blow off my carboy. It made a mess on the floor, but I managed to save the batch. In any case, there is no downside, whatsoever, to using the 'tube and bucket' method to replace the airlock. It's the only way, in my opinion. (And it smells so good bubbling up through there!)

[@BigDawgTheGreat]

I am currently fermenting my 2nd batch with this system... I found that on higher gravity beers starting out with a 32oz wide mouth mason jar works pretty well. It seems using a stepped system will work. Start with 32oz, and then go to a 8-16oz when going into secondary. I racked to a carboy on my first one to free up for another batch, so I am curious on how well the sediment on the conical walls will settle when left in extended secondary. I haven't bottled directly from the fermenter yet, but I almost think the bottling attachment is better suited for a clean way rack to a secondary need be. Also for extract brewers doing partial boils, make sure the ball valve is closed until all your wort is in and filled to the markers. The fill markers are only accurate with ball valve closed as they will not account for the volume of the mason jar.

[@akajondoe1]

I was on the fence about buying this product, but I think I will give it a try after my next batch. I want to upgrade from 1 gallon batches to 5. I will probably still bottle for a while. Thanks for the information. I will definitely subscribe.

[@BEERNBBQBYLARRY]

You’re welcome. However, for a lower price, there are better options available nowadays that can do more like pressure fermentation.

[@brandondiem9415]

I have brewed with mine a few times and have a larger mason jar to collect the trub. I will wait 12 hrs after I transfer the beer to the fermenter and remove the trub / mason jar and repeat before I pitch my yeast. I do this to minimize the beer loss. I will typically only remove 1 more time after primary fermentation has stopped to harvest the yeast.

[@brandondiem9415]

I will chill down to 80 deg and transfer to the fermentor. cover it up and put an airlock on it- this keeps the wort safe while it clears up and chills down overnight to the ideal pitching temp. I have not had any off flavors. So far it has worked like a charm.

[@douglashenderson1481]

I have the same system and one thing I think is the biggest deficit with it is trub when dry hopping. As you mentioned its meant to be an all in one method but when you do hop additions for the dry hopping of beers you cannot use a bad to hold hops due to the butterfly valve. This has caused me to also lose quite a bit of beer.

[@joshuapinter]

?? Use magnets to attach the hops in a bag to the lid. Then just remove the magnets when you want to dump the hops in.

[@bgilmore3]

I recently got one of these in a Craiglist batch of brew gear. It came with a purpose made jacket with handles duplicating what a brew hauler could do. So I know that is something they sell. Also, I am sure you can use a standard Brew Hauler if you just adjust the straps a bit. Hope this helps.

[@BEERNBBQBYLARRY]

Thanks. I have one of those jackets as well. Did a follow up video on it.

[@BrewNub]

Really enjoyed learning more about the Catalyst. My friends and I have been brewing and filming for a while for our channel. We're getting to a point where we want to upgrade, so we can do 5 gallon batches easier. How is the Catalyst after a handful of brews or a year later? Does it still hold up?

[@BEERNBBQBYLARRY]

I actually gave this and all my other conical style fermenters away. This model had a real bad problem with the seal coming off and hard to put back on. Since I don’t bother with dump valves usually anyway, I went back to using regular bucket style fermenters.

[@BrewNub]

We did our first five gallon last week and the glass carboy makes me really nervous lol. Feels like a lot can go wrong with that much beer fermenting. Think we will go the bucket route until we find something we like. Thank you for the quick response.

[@BEERNBBQBYLARRY]

There are more Bucket style options that just a bucket and carboy. I have several products that are Bucket style; a FermZilla All Rounder, a Fermenter King Snub Nose, a Fermenter King Jr, a Spike Flex, and a Kegmenter.

[@GunnySGT1911]

Nice review. I've been keeping an eye on these. I have a Fast Ferment conical that I love. My only complaint is the small 1" opening to the collection bulb. If you allow to much trub (hop bits and proteins) into the fermenter, you will need to take steps to clear it during fermentation. The larger opening on the Catalyst is an improvement. But the Fast Ferment has a 7 gallon capacity and a domed top which in my experience and use makes blow-off tubes unnecessary and a normal airlock is all you need. I also like the clear material used by the Catalyst. It allows you to see just how much trub you have, how fermentation is progressing, etc. The Fast Ferment is more opaque. You can sort of see through it, but not clearly. The Catalyst costs twice as much as the Fast Ferment, $199 compared to $99. The advantage is that it comes with a stand. The Fast Ferment has 2 different sized stands available and will run you about $40 for either. The Fast Ferment does have the advance of an included wall mount, and an optional carrying strap. Hope this helps anyone trying to decide between the two.

[@GunnySGT1911]

BEER-N-BBQ by Larry I haven't noticed any problems with the small amount of air that gets released from the collection jar. If my understanding is correct, the air released is lighter than the CO2 produced from the fermentation process. It would naturally rise to the highest point in the system and thus would be the very first thing expelled from the airlock or blow-off tube. I also find that the turbulence created from the rising air helps to dislodge some of the trub collected on the conical part of the fermenter thus allowing it to settle in the jar. Gentle tapping around the base seems to help do the same, but I think the rising air bubbles causes more to fall and also helps release CO2 built up in solution in your beer. Really liking your videos and the way you take time to explain some of the smaller things others take for granted. Cheers.

[@danielpedroso4311]

BEER-N-BBQ by Larry I have a Fermentasaurus (conical fermenter made here in Australia). Similar deal, but the fermentasaurus can be pressurized. What I do when reattaching the trub/yeast collection bottle is to purge it with CO2 (from my kegerator). This way the chance of oxygen getting into the beer is almost nil. I also use CO2 to transfer it from the fermenter (which is already under pressure at this point, and the beer is already carbonated) into the keg (already purged with CO2). Since getting this thing, the quality of my beer has increased significantly, and it saves me so much time - I don't have to syphon the beer into secondary, can harvest yeast and get the next batch fermenting instantly, and don't even need to wait for the beer to carbonate - it carbonates naturally while fermenting under pressure. The down side is that I waste a lot of CO2 - but I don't really mind, it's pretty cheap around here.

[@SuaSponte75]

try using a hop spider and hop bags (boil and dry-hopping). No trub when transferring to fermenter or racking out to kegs/bottles. ss chronical with the blow off cane was a great investment for me. has trub/yeast valve and separate racking valve. plus pressurized transfers to kegs or brite tanks

Brewing tips aside I'd love to meet Larry, he seems like a good guy

[@DrHansBrewery]

Great review Larry! Each time you changed the jar you also introduced oxygen in the beer. That's a problem with systems like that. What you can do is to fill the jar with beer or boiled water when putting it back. Or try to push out the air with CO2. But that's a little easier with the fast ferment. Cheers!

[@randyschalck5961]

Larry did you really put a CAD drawing of the fermenters on here? Awesome! Great job comparing the two. Thanks for sharing.

[@kennethcunningham8624]

Do you feel that you are inadvertently oxygenating when you change out the drain bottle from the bottom when you re-set the valve?

[@cubanken]

BEER-N-BBQ by Larry thanks Sir, I'll look into it.

[@LiveHealthyWealthy]

I don't think any oxygenation occurred due to the Co2 in the blow-off tube, as long as the end of the tube remained under water. I would think that only Co2 was drawn back into the vessel. It would be safe to remove more trub after seeing additional Co2 exhaust bubbles.

[@bradleypariah]

+LiveHealthyWealthy, I think you're missing the point. The Ball jar was full of oxygen, and when it was affixed to the fermentor, it was empty, and when the valve opened up, the oxygen from the Ball jar bubbled up through the beer, pushing CO2 out into the blow-off. The beer touched O2, and that's the concern. Larry said it didn't hurt anything, so whatever, but that's what Kenneth was referring to.

[@LiveHealthyWealthy]

Ah, I got you. I thought he purged the Ball Jar with Co2 first...

[@just_george_]

i really appreciate your video. by any chance, anyone try using this fermenter for winemaking? thanks for your time and comments

[@killswitchh]

How easy would it be to add oxygen to the fermenter when you remove the airlock to dump the trub? Doesn't that suck in oxygen or does the co2 on the bottom keep it from touching the beer?

[@BEERNBBQBYLARRY]

Air will get pulled through the airlock or airlock opening if you remove the airlock.

[@killswitchh]

@@BEERNBBQBYLARRY Yeah that's the major downside introducing so much oxygen. I think it might be fixed by slowly opening the dump valve while having your co2 hooked up through the stopper at like 2psi.

[@BEERNBBQBYLARRY]

@@killswitchh if keeping out air of your concern, you’d be better off with a pressure capable fermenter.

[@killswitchh]

@@BEERNBBQBYLARRY Not trying to sound like an ass but shouldn't all brewers be concerned with not introducing oxygen to the fermenter?

[@Mystic_Kal]

I apologize if what I am about to say sounds bad, I don't mean for it to, but I cannot take your critique seriously. You say using a blowoff tube is taking a step backwards, but that is a technique used by most professional breweries. But that's neither here nor there. You would most likely have been able to get away with using a simple airlock had you not poured that extra galling of sludge into the fermentor. You racked the wort off of the spent hops and excess mash, why add it back? You left yourself with only two quarts of room at the top. Any decent fermentation would guarantee the need for a blowoff tube with that little space between the beer and the lid. As for dry hopping, I think using the removable jar to dispose of the spent yeast before adding the hops to the second ferment would work fine. It truly seemed to me that any trouble or problems you had with the system were brought on by yourself. I don't know if it was a one time issue of laziness or poor habits or bad brewing practices, but it seems they are easily corrected mistakes. The one issue I have with the system is that the unit is clear and thus the beer is open to exposure to light.

[@glenm125]

The towel I wrap around my glass carboy is pretty opaque, especially when I use a beach towel and get a couple of wraps. No reason why that shouldn't work here too, and no special care required as might be for a custom jacket if it has zips or crap or weird materials. Re buckling, I think he said it pushed the airlock out first .. I've enjoyed this phenomena 5 or 6 years ago with a simple bucket fermenter, I called that batch "Brown Spots on the Ceiling".

[@glenm125]

I've noticed my stickons seem to lie as well. More so as they get older. Unlike me, of course. Does this whole comment sound like that classic oxymoron, "I always lie"? heh

[@Gabesafish]

Geoffrey Splendorio about halfway through this video, I had anticipated you would have airlock suck back issues once you started bottling or kegging. To me, this negates one of the major benefits to using a conical, specifically being Oxidation medication. You're obviously sucking air back in when that happens, thereby exposing the beer to oxygen. I'm sure there's got to be a way to retrofit this so that you're doing it under an inert gas blanket, but that's additional expense/complication and yet another potential vector for infection.

[@Idontwantagoogleyoutube]

the same surface area of liquid is exposed to oxygen for the entire process of decating, both on top of the liquid in the fermenter as the level goes down, and on top of the liquid you are decanting in the keg as the level goes up. there is no additional exposure of the liquid to oxygen by this method

[@martinmoore6971]

It really depends what you are comparing it to. It is a step backwards when compare to the grain father conical fermenter, for example.

[@raiseyourvibrationalstate]

Great video Larry. I know it's been one year but I'm wondering if you are still using this system? I think I'm going to get it and just put a giant jar underneath and wait for 2 and a 1/2 weeks before dumping it and do it all at once so I lose minimal beer

Excellent video, very helpful. You kinda miss the point of the conical Fermenter, by default the drain vale is close. only when fermentation 70% done you can start removing the trub which are very beneficial to the yest and Fermenter process. next is removing yeast (secondary fermentation) all in all you work layer by layer keeping the drain valve close til you need to remove bottom layer off.

[@meganmcgrory7525]

wonder if you could even further reduce the introduction of oxygen into your ferment by loosening the air lock when you add the sanitized jar back on for collection and letting the trube drain down a bit before locking the jar on or pre filling with a sterile water/wart that would also reduce the amount of fluid loss? thoughts?

Thank you for this great video. I recently receive one for my birthday, but I'm having a lot of trouble unscrewing the mason jar because the adapter moves along with it. Each time I've changed the jar, I've needed another person to hold the adapter as I'm unscrewing the jar. There appears to be a great deal of pressure build up between the jar changes. I've tried leaving the jar a little loose, but it leaks. Do you have any tips for me? You make the jar removal look so easy.

[@BEERNBBQBYLARRY]

You could try a strap wrench from a hardware or auto parts store.

[@LouB3rt]

if you ever want to lager in the system (where you don't have to secondary ferment transfer, or you don't have a fridge large enough for a fermenter) there is something called a brew jacket, that is a cooling system and they make one that fits the Catalyst.

[@joshuapinter]

They also make a custom built coil and lid for this that allows you to circulate glycol through it. I use it with mine and it's phenom. Love it so much. I hope they don't go out of business and maybe even make another version and a bigger, 10 gallon one.

[@lbatesjr]

I think a lot of the Catalyst but one of the issues I have with it is, the gasket on the lid often will come loose if i try to remove the the top to add secondary hops, or flavor additions... Have you run into this? it's a pain when all you want to do is crack it open a bit and put in the additions.. Then I end up having to re-sanitize the lid, gasket, airlock... and putting the gasket back on can be a little timely as it doesnt always cooperate.

[@parnilsson8283]

Hi Larry, thanx for another intresting video. Concerning the catalyst I have one comment that i think could be applied to all conical fermentors with a trub removal system. I am concerned that if one removes several times the jar with the trub the effect would be to introduce a considerable amount of oxygen into the beer. Personally I do not transfer to a secondary anymore , and leave the beer in the primary all the time (i think u mentioned in a video that u do the same). I use a regular fermentor with a tap. Bottling from the tap and leaving all the trub behind works just fine.

[@parnilsson8283]

Intresting. It makes sense that big bubbles get through rapidly and out of the vessel. I never though of it in that way. In any case, as you also suggest, I think that the knowledge that one can leave the beer in the primary all the time, takes out part of the supposed advantages with conicals. Still thay are useful for collecting yeast and for the trub concerned. I will find and watch the video you mentioned

Aren’t you introducing oxigen everytime you connect and disconnect the the trub removal jar?

Yes but not as much as you might think. The large bubbles pass right through and out. Large bubbles have less surface area. Less surface area means less contact with beer during the brief time they are in contact. This lack of surface area and contact time is why you need to use a diffuser stone when you oxygenate wort prior to fermentation for example.

I have one of these also and ran into the same problem with the lid design. I think it's bass ackwards. It should have been domed rather than sunken in.

I was convinced by my LHBS owner that I wasn't supposed to have too large of a vessel because extra head-space was bad. I was brewing in large buckets with air locks, but to switch to all-glass fermentation (5-gallon, filled all the way to the neck), I had to switch to a 2" blow-off. To me, I felt like I was graduating to a blow-off system, because although krausen can lend bitterness, I was told it was an unclean, masking sort of bitterness. Filling the 5-gal carboy to the neck ensures that all krausen exits the vessel during primary. The beer I'm drinking at this moment is the best beer I've made in my life. Could be anecdotal evidence. Just funny to hear an alternate point of view that positions blow-off as a step back. LOL I thought I was cool!

any fears of oxygenation from removing the trub over and over?

[@dcuccia]

I've found bigger wide mouth Mason jars work fine, too - been using a 32 oz jar as my default and that works well for one change to "secondary"

Excellent job, great review.

What that a Chief Illiniwek jacket?

[@newfyguy2000]

@@BEERNBBQBYLARRY ah, I just caught a glance over your shoulder. I grew up near Champaign and am a lifelong Illini fan. Thanks for the great videos. I've just begun my pomebrewing journey. I actually bottled my first batch today.

[@northernbeattie304]

One question, Catalyst or Fermentasaurus??

[@starrychloe]

7:20 Oops you sucked up some of your drainage water when you opened the valve. Better to vent the top when you open the valve at the bottom.

[@basingstokedave4292]

can i get this in the uk

[@preetdatta5353]

Give details of technical support aspects

[@markyman2]

Great Review Larry classy videoThank for that keep up the good work.

[@yonceydelatorre3802]

No filtering?

[@davegravitt210]

The Fast Fermenter is more inexpensive than the Catalyst. Also with the wall hanging brackets that come with the unit then keeping it up and out of the way. I switched from buckets to it.

[@martyonthebeach]

Very helpful video!

[@knarfster]

Can't you use the brew hauler on the conical fermenter?

[@BEERNBBQBYLARRY]

Never tried. I used their lifter/cover combo while I owned this.

[@torjones1701]

If you want to avoid adding more oxygen to your brew mid ferment, fill your ball jar with water before reattaching it to the fermenter.

[@torjones1701]

Fair point, though simple enough to fix, degas the water, or if you want something that'll do the trick easier and cheaper, carbonate the water with either CO2 or N2. If the water is carbonated with either of those gases, then the amount of O2 it can hold is reduced by the amount of those gases in suspension.

[@torjones1701]

Easier is not necessarily better.

[@cmstudios11]

in order to eliminate Trub I just use a nylon bag to throw my hops in during the boil. It saves me lots of tasty brew.

[@oldschoolman1444]

I use whole hops, no bag or hop spider and a braided ss mesh screen from a supply line in the bottom of brew kettle and whirlpool before it goes through cf chiller. Always nice and clear wort in the fermenter.

[@marks208]

Please, also send out your recipes for any of the BBQ videos if available. Nothing like a nice cool Homebrew with some Good Q, Slaw, an Baked Beans!

[@vikramsagar4764]

Were is Catalyst ?

[@DokterKattenbakvulling]

Why not cold crash? too large?

[@hullabaloobrew2056]

The yeast you used is what caused you to have to use a blowoff hose.

[@marks208]

Great video and very informative! I want to get one, but I'll wait til they make the "improvements" you mentioned. Just one thing Larry, in the video I see you're wearing socks....perhaps some kind of foot gear to dress it up a little? Thanks for the honest review! mark, Toledo, OH

[@marks208]

You must live in a very clean house! Mine is rather dirty....it's so dirty that people wipe their shoes when they leave. (Joan Rivers on Johnny Carson show).
