Good idea, but some flaws
I bought one at NHC this year and just started using it. The biggest issue is the seal on the lid. It comes off very easily when removing the lid and is almost impossible to put back on. I had to transfer my first beer out to a bucket as I couldn't get the lid seal back onto the lid. This is going to limit my use, I hope the seal is redesigned to be more user friendly.

I love this system!
I just dumped the trub on my first batch using the system. I don't have a ton of room in my apartment so having multiple carboys and buckets has always been a hassle. This has eliminated all the headache. I siphoned the beer straight from the kettle to the catalyst and pitched the yeast. No drips leaks or anything. Today primary was done and I switched the jar out to collect the yeast. No issue, just make sure you have a small plate to catch the liquid that sits on the top of the jar. If you are brewing a heavier beer I would suggest a 24-32oz jar as the 16 fills up quickly. I purchased those two and the first batch has settled nicely into the 24. The only CON I have seen is the lid latches. They have to be aligned right as they are cut to fit around the top so just make sure its aligned press firmly to seal then secure the latches. Fantastic product and you can see pics on Instagram texaviator23

Good idea, well executed.
Once you think about it, the design is a no brainer. It takes most of the headache out of home brewing, and does it solidly, simply and elegantly. Would definitely recommend.

Great concept, needs work
Pro/Con list at end of review.

Got this setup for Christmas this year.
Overall, I think I am going to love it. Easy to use, great quality, item that does what it was advertised to do: Brew beer while lessening the potential instances for contamination.
I love the system, don't get me wrong. But it needs quite a bit of additional design work/modification to make it a five star item.
I am an early adopter, so I am accustomed to 1.0 version items I get having a few slight "flaws". Again, overall, the system is a superior fermenting system.
BUT
There are a few things requiring a little tweaking, in my opinion. Most are simple ease of use issues, but I do have a major issue with the design of the bottling attachment, which is the reason I only give it 4 stars rather than 5.
The screw-on attachment for the tubing to bottle the finished batch is very very slim and will not work with standard 3/8 tubing (and yes, in a hobby like this, I recognize there are no hard and fast "standards"). Normally, I don't think this is that big of a deal, but bottling out of this system is gravity feed/kink the hose and waste beer only: SLOW and messy. I was able to force my bottling wand into the skinny tube that fits the bottling attachment, but only because my wand is old and starting to show signs of crazing. Normally I don't use a wand in that condition, but I consider myself to be lucky I hadn't tossed this one yet since none of the others I own would fit.

Overall, I love this thing. I will continue to use it. I will probably buy another just for ease of use... but it needs a little work to meet the 5 star mark in my book.
Pros:
Superior concept
Easy to assemble and use
High quality materials
Complete package

Cons:
Tall system makes filling with water to sanitize a challenge
Threading on lower valve is the same direction for both trub jar and fermenter attachment
72 degree temp limit will not allow ice cooling method
Bottling attachment tubing too small for bottling wand
Lid seal difficult to re-install in a sanitary manner
Lid too large to fit inside of fermenter necessitating separate sanitization vessels
Clear fermenter has no light blocking ability
No safe way to handle/carry just fermenter section.

Cool concept, but no
First its very cool looking... And the jar is great idea.. However..

You add a jar? Air shoots in EVERY TIME.. terrible.

Yeast can get stuck to the side and not move down. So when you bottle or keg, its Coming into the party. Not Cool.

Not Bad but could use some upgrading
I recently received this system for Christmas and used it for the first time today. In general it is a pretty well built system but the lid needs changing. First, if the rubber liner on the inside comes out good luck trying to put it back in. Unfortunately mine broke trying to re-assemble after cleaning. I also do not like how the lid attaches to the fermenter. If these two things can be fixed I think overall it will work out just fine. I am in the process of fermenting now so I will try to update later and maybe increase the number of stars if I find it easy to bottle.

great idea, rushed to market
I love everything about this except for the seals....which are very important. The bottom leaks when you seal it and unscrew the mason jar to put the drain funnel/tubing on, lost about 5 oz of beer on my table and the gigantic o-ring on the lid is annoying to put on every time i take the lid off...fix the seals and this is a 5-star item.

Overall good, but with reservations
I have used the CFS twice with mostly good results. I agree with the first reviewer that, if you lift the lid, the lid gasket loses its position on the thin inside rim onto which it fits for a tight seal. It isn't possible to realign/reinstall without cleaning the gasket and lid before repositioning (leaving beer exposed). Fitting an airlock with hose for blowoff worked the first time, but on my second brew the blowoff also oozed through the side of the lid and onto the floor. Even though the gasket was in position, the lid clamps don't all grip and lock down with equal pressure. Lastly, while the dump valve is awesome, it seems that the plastic surface of the conical, while hard, allows for yeast further up the slope of the conical to stick to the surface and not fully purge. I'm still committed to making my investment work, but am beginning to believe that stainless steel is the only way to ensure that you're working with a foolproof non-transfer fermenter.

Primary Fermenting Now
We brewed a brown ale this past weekend and have it fermenting in the Catalyst now. The review about the seal easily coming off the lid is true, but it was not difficult to put back on with two people. Transferred straight for the kettle to here. Pitched yeast and two people shook the entire system by rocking back and forth. Although the complete construction is plastic, the base, valve, and "carboy" seem very sturdy. Using a 20oz wide mouth jar to catch the trub.

Great with little tweak
I received the catalyst fermentor as a Christmas gift. I brewed my first batch and 2 weeks later tried to empty the trub but could not. I had to transfer beer into a secondary unit. I contacted Northern Brewer and was told that the valve needs to be left open during the process so I tried another batch. What a difference. Customer service was great and i got back on schedule using the new fermentation system. Love it. My only gripe is that the manufacture should make the instructions clearer about the position of theh valve.

I see that you include transfer tubing with this. Where do you hook the transfer tubing up? I don't see a spigot anywhere. Do you have to siphon this to bottle the contents or is there an attachament point around the butterfly valve somehwere?
A shopper on Nov 24, 2016
BEST ANSWER: The bottling attachment screws on, replacing the mason jar. The tubing connects to that.
How do you aerate the wort with this system? Currently fermenting with buckets and shake them vigorously before pitching.
A shopper on Dec 9, 2016
BEST ANSWER: I use this as a secondary to get all the trub out, I would still use a carboy or bucket as the primary.
WIll there be too much head space foe a 3 gallon batch?
A shopper on Dec 3, 2016
BEST ANSWER: ya its pretty huge
Since I don't have the luxury of a dedicated, heated, brew space, I have to haul the primary fermentation vessel to a different location to ferment after filling. How do I move this container? Are there sturdy handles that allow me to move it easily?
A shopper on Dec 31, 2016
BEST ANSWER: I'll answer my own question, no handles to grab at the moment but it appears that there is a "new" cover that has straps that allow for transport due out the end of January 2017.
Can I make wine in this system? I am new to wine making and this seems like a good deal. Thank You
A shopper on Dec 27, 2016
BEST ANSWER: yes
How is fermentation temperature measured and controlled?
A shopper on Dec 18, 2016
BEST ANSWER: I use a thermowell and probe. Works fine
Can you use a heating belt to control fermentation temperatures with this product?
A shopper on Dec 8, 2016
BEST ANSWER: Yes. I am using a heating belt and it works fine. It doesn't fit snug around the tank due to its shape but it still does the trick.
Will this fit in a small chest freezer. I have a small chest freezer that easily holds two carboys. Anybody?
James R on Nov 27, 2016
BEST ANSWER: If your chest freezer inside dimensions are larger than those stated it should work.

The Stand: Height: 14.75" Width: 17" Depth: 13.75"
Unit Size: Total Height (does not include airlock): 26.25" Maximum Width: 17"
Can I drill it for a sampling port?
A shopper on Dec 26, 2016
BEST ANSWER: no
Are the lid, gasket, and valve dishwasher safe? Or just the tank?
A shopper on Jan 17, 2017
Will the rubber stopper or lid support two "holes" one for gas/pressure relief and one for a thermowell for fermenter temp control?
A shopper on Dec 29, 2016
how do you get the gaket back in?
Wayne C on Jan 7, 2017
BEST ANSWER: I had this same problem too. The first time I reinstalled it, I put it on like a bicycle tire, starting at one end and worked my way around the lid. However, as the gasket began stretching, it popped off from the area I started before I could finish. I ended up having my son help hold it down as I installed it around the lid. That did the trick. After brewing my first batch, I removed the gasket for cleaning and immediately reinstalled it. This time, it seemed to go on a little easier, but I still had to hold it down with my elbows as I finished stretching it around the lid.
Does this still use an airlock and stopper? If so is it included? Or will it accept the standard size stopper and airlock?
A shopper on Jan 20, 2017
BEST ANSWER: Yes utilizes an airlock. Stopper. provided, but you will need your own airlock
How do you get any yeast that clings to the walls of the fermenter off before bottling?
Ford S on Jan 14, 2017
BEST ANSWER: its so minimal it wont matter and if it stayed there during drop-out it likely wont end up in the bottles, but u can remove the lid and DELICATELY rub the sides of the conical with the trub trap closed, then put the lid back on and open the trap again then wait a couple hours (or a day). as good as it gets
How do I change my jar? Close valve, remove jar and replace worth new sanitised jar and open valve again?
Doug M on Dec 26, 2016
BEST ANSWER: exactly but be careful it will leak a little bit
What is the size of the tube hole? So i can put a bottle filler on the end of one
A shopper on Dec 18, 2016
BEST ANSWER: if you soak it in hot water first, its a tight fit tho
Is this product good for the " No chill method " HDPE construction?
A shopper on Dec 11, 2016
BEST ANSWER: yes
Has anyone attempted to drill the catalyst fermenter to add a sampling port? I was thinking I could bottle off the sampling port as well rather than using the provided bottling attachment.
