Great but a few of important things to remember
There are enough videos on youtube reviewing this so just reference those. Overall, great product but a couple of important things to consider that the reviews don't tell you. (1) Teflon tape is key, consider buying more for where the ball collect connects to the union valve as you might have to reapply overtime. The other areas where you apply teflon tape will only be a one-time job. (2) Make sure the lid is on right, sometimes if you're not careful when screwing the lid on the lid o-ring can fall into the fermenter. (3) Can't stress this enough - Make sure the bottom of the union valve is screwed on tight. You can actually tighten it by removing the red lever from it and screwing it tighter using the red lever as a tool. I never did that and it was leaking like crazy when I switched to secondary fermentation. Keep those in mind - otherwise awesome product. I will be buying more here soon.

more troubles then it's worth
first problem the lid does not seal well, even with the replacement silicone gaskets, I have 2 of these fermenters, second the bottom clogs and you may have to siphon into a secondary anyway, this happens about half the time at least with all grain brewing, third, after about 8 batches, the lid split on the edge and contaminated the batch, so there goes half the cost of the fermenter down the drain and the other half on the time lost brewing the batch, I'm going to go back to buckets, and use these for cider and wine making, they are a bit more forgiving then beer and won't clog the drain,
January 23, 2017
More work than buckets
The siphon less big mouth bubblers or old school buckets are more effective than this device. -Trub coats the lower 30% of the cone and the drain valve is constantly clogged. I have to rack to a secondary anyway to get clear beer for bottling. -You will have more batch waste dealing with this. -It is harder to clean than a bucket. -1/3 the beer making capacity than if you spent the same $ on buckets or bubblers.Note: I brew heavily hopped recipes. If you brew very light Budweiser style beers, this might work great.

Making clear beer is easy with this conical fermenter.
The FastFerment is a great concept but suffers from quality control issues at the manufacturer… I have two of these units now and all of my issues have centered around the union valve. The first unit came with PVC fittings that were mismatched (the threading for the “bottling tube” attachment and the “collection ball” were not the same and not compatible with each other). After several weeks I received a replacement union valve from the manufacturer which resolved that problem. On the second unit, the union valve leaked right out of the box. It’s kind of difficult to describe but basically the threading on the inside of the valve (yet outside the o-ring seal) leaks. This is the threading that the inner components screw onto to keep the whole thing together… Bummer… Luckily I kept the mismatched valve that was not leaking and, in order to save brew day, I went with the other attachment. Since then another issue has cropped up. Seems that sticky wort has a tendency to cause the bottom attachment of the union valve (the part that screws onto the collection ball) to stick to the o-ring like glue. This makes removing the collection ball very difficult and has resulted in inadvertantly unscrewing the inner portion of the union valve causing it to leak… I went to the biggest local commercial plumbing supply store and was told that you generally never dis-assemble a union valve and he was not aware of any tool to fit the notches to tighten it back up. So, now I have two leaky valves and am not sure what to do about it. Also, be prepared to use a utility blade to clean up the plastic seams on the parts as there was a lot of scrap left over from the molding process.

I tried. I really did...
I watched demo's, video's, forum comments, etc. and was excited to convert to this in my brewing process. But... I am so frustrated by how much sediment, hops, etc. that gets passed on to my keg. This is the one thing I introduced into my bucket process that really screwed things up. I unfortunatately cannot give this a good review. I also even tried just making it my secondary for hops additions. You can't drain it because it's plugged with hops. Siphoning is also troublesome (which beats the point of even having this thing).Much more R&D needs to go into this before it's ready for a homebrewer.

Valve Cleaning
Pay special attention to cleaning the inside cavity around the ball in the valve. This area collects material and is difficult to remove. If you are still have odors after cleaning the fermenter, they are coming from the valve. Open the valve just enough to get a small opening ~10%, and immerse in your sanitizer, allowing all the air to come out, Close and shake. Repeat.Overall a great fermenter, and it IS faster. I have done 6 brews with it, and all have turned out well.
November 21, 2015
Great Concept, hoping it pans out!
I am still middle of the road on this item...

TONS of headspace
Collection bulb is an amazing idea
Large opening for cleaning
Easy screw connector (fermenter - bulb)

Gunk builds up at ball valve.
TONS of tape needed for connections and even then they still tend to leak just so slightly.
Not enough clearance when using the stand to detach the bulb. You still need to lift the unit to free up enough room.

I have to way overdue it on the tape to even remotely seal the connections. I did the "break in" process and everything for the threads. The bottom connection before the ball valve always builds up a tiny amount of wort. I would silicone seal them, but I still break everything down to clean. No way I would not take apart those connectors to clean, they get way to nasty. Even with all this I still like the unit. I would love to get another one, but I just cant see paying that price for something that is supposed to be "easier" but still presents its own issues.

Maybe good for wine
Good: Easy to keep the batch from getting infected. Bad: I had too much sludge at the bottom for the beer to get through for bottling. Half the bottles end up with hops and dead yeast. I also had to stick a wire up the open valve to get the sludge out. It was packed in good. Also, some of the parts seem to be for a different model as the hose collar's threading does not match anything in the kit. I'm guessing that this does not work for product with a lot of particulates.

Valve plugs poor quality construction
I have made two batches of wine and one batch of beer in this unit. I wish I had not purchased it! Save your money.

1) The cap casket is not durable. They should have used silicon FDA rubber.

2) The connection at the bottom are hard to seal and to get the bottom ball of is not easy. I have the stand and only a small plate will fit under the ball.

3) The worst issue is that the near opening in the valve clogs during settling. This is the primary feature of the unit and it does not work especially for wine.

My first use of FastFerment - Ruined Batch - Union Valve Defect
After first batch was ready for transfer to bottling bucket, I closed the valve and removed the collection valve. Wort was gushing out of valve even though it was in the closed position.Turns out that the seal of the union valve was not properly tightened at the factory.Poor quality control!!

Will this work with a Fast Fermenter?

FermoTemp™ - Electric Fermentation Heater
FermoTemp™ - Electric Fermentation Heater
BEST ANSWER: Sorry, but I don't know. I haven't used a heater with my Fast Fermenter. I love my Fast Fermenter though. Well worth the money in the convenience it gives you alone.
Are people adding priming sugar directly to the fastferment? I saw a video on youtube where this stirred up yeast (he had removed a bottle of trup from the bottom) and caused a blockage. They recommended bottling and using priming drops. Thoughts?
chris h on Jul 13, 2016
BEST ANSWER: We'd recommend using the by-the-bottle priming methods, like Fizz Drops, rather than stirring up the beer in the conical fermenter. The other option would be to gently rack it into a standard bottling bucket and mixing in priming sugar the regular way, and bottling from the bottling bucket. - Mike W, Northern Brewer
Does the lid come with the airlock and gasket to keep the airlock in place or do I have to buy separately? Sorry if this is a silly question but I'm a new brewer!
Robert J on Feb 20, 2017
BEST ANSWER: The lid comes with the big inner gasket that fits underneath the lid and when it screws onto the container. And it also has the gasket in the small hole in the lid where the airlock would fit but it does not come with an airlock. You would have to buy that separately. If you're considering getting the fast fermenter, do it. I love mine! Very convenient compared to carboys!
Can you brew 1 gallon batches in this?
A shopper on Jan 28, 2017
BEST ANSWER: You could, but you really wouldn't want to. You'd lose much of your one-gallon batch in the collection ball. FastFerment recommends it for 5-gallon batches. I've used it for 2.5 gallon batches, as well. It just wouldn't be worth the trouble for what you'd get out of a 1-gallon batch.
Does anyone know how to prevent the ball valve from becoming clogged with the trub/yeast cake? After the primary fermentation is complete, I open the valve to drain it and nothing happens because the trub/yeast cake is too thick to flow through the ball valve.
H O on Sep 4, 2016
BEST ANSWER: After removing the trub ball I fill the ball with clean water that is warmer then the fermenting wort above. This causes the water in the trub ball to rise through the valve which loosens up the valve blockage. I will also use some kind of vibrating device on the valve if in a hurry. A cheap back massager works well. I won't transfer till all the trub is removed. Good luck.
Wouldn't you introduce oxygen, possibly contaminating the batch, while opening the valve to collect trub in the collection ball?
A N on Jun 5, 2015
BEST ANSWER: Contamination shouldn't be a problem as long as you sanitize everything. Introducing O2 is a problem if you don't take measures to prevent it. There are a few options. You can fill the collection ball with sterile water, but it will dilute your beer a little. You can purge and fill the collection ball with CO2 right before you attach it. You could also fill it with the same, or very similar beer, if you have some (about 25 oz). If you're just using it for primary fermentation, attach the collection ball, open the valve, and leave that way until primary is done. Then close the valve, remove the ball, and attach the hose to transfer the beer to a keg, priming bucket, or another secondary. I wouldn't recommend keeping the valve closed through primary and then attaching the ball at the end to try to get the yeast. Depending on how much yeast and other material is in there, it may clog the valve.
Does it come with the wall mount or stand or do I buy that separately? Thanks!
M A on Nov 21, 2015
BEST ANSWER: The FastFerment comes with the wall mounts

the stand is sold separately.
is there a loction inCanada Alberta pincher creek
S A on Nov 20, 2015
BEST ANSWER: I would try contacting the manufacturer! I hope this helps! Cheers!
When dry hopping with pellets do I leave the collection ball open and let them settle into it, won't they all be confined in the ball and not in contact with bulk of beer?
D T on Oct 23, 2015
BEST ANSWER: Either way will work. In general hop pellets will disolve, float on top of the liquid, and eventually stick to the sides of the fermenter. I always keep the ball valve open as to collect the most amount of sediment possible. Closing it can potentially cause the beer to become aerated and suspend the remaining sedement. After removing, emptying, and reinstalling the collection ball, that is. It will work either way. I'm sure you are overthinking it. We all do!
Will brewing heavy hopped beers cause the collection ball to clog?
A shopper on Sep 6, 2017
BEST ANSWER: After the boil I let the wort flow out of my Bayou Classic spigot slowly, which usually holds back a lot of the hop sludge - preventing it from clogging the FF. If you have to pour your kettle into this it will likely clog, and I've been there and it's not very easy to fix (unless you get lucky on your secondary and it pushes it through). IMO - The Catalyst Fermenter seems like the better option. Even though it's twice the amount, I would have considered it a long time ago over the FF.
Can one use the same fermenter for wine and beer?
R K on Jul 5, 2016
BEST ANSWER: Yes, you can use this for both beer and wine. Just make sure to give it a thorough cleaning between batches.
What's the width of the thermowell? I use an Inkbird ITC-1000 which has a sensor that is just shy of 1/4" diameter. I want to know if I can use the thermowell to hold the sensor, or if I'll need to come up with another solution.
Jerad G on Jun 13, 2016
BEST ANSWER: The thermowell has an outside thread diameter is 1/2" NPT. The Interior width where the thermometer is inserted is 9mm wide and 3" deep. The thermowell is not threaded on the inside.
How can temperature be controlled in the fast fermenter. I use a firm wrap and temperature controller with my buckets and carboys
B K on Dec 7, 2015
BEST ANSWER: For ales, the FastFermenter temperature control is acceptable. I use a Blichmann thermometer. If you want to make a lager, one way is to install a secondary valve to the FF and recirculate the beer into a cooler fitted with a coil. Other more fancy option is to install a SS coil on the lid and recirculate cold water using a cooler as a reservoir. You may get one custom made at stainless steel brewing. Talk to Zack he is a cool guy.
cost to ship to Canada Alberta pincher ceek

BEST ANSWER: Sorry we can not ship internationally right now.
In primary should I have the collection ball open or closed?
R H on Nov 17, 2015

You'll want it open. Otherwise you'll get a pretty big air bubble if you open it later!


Is there any recent fix for the lid top gasket ? i thoroughly enjoy using this fermenter except when it comes to sealing the lid it is a nightmare !!!
T H on Oct 31, 2015
BEST ANSWER: Worst fit and finish ever! I bought 2 that were not too bad and could be forcibly tightened, six months later bought 3 more. The last 3 had a re-designed gasket that is much better so I purchased and replaced the original 2 gaskets. BUT... the threads on the latest ones had so much casting flash that I could not begin to start one of them and the others would start but only tighten half way down to the gasket before stopping. I had to go after the threads with a dremel tool, file, and sandpaper to clean up the threads on the vessel (caps were fine). Now all 5 of mine are smooth and can be turned all the way down to the gasket making contact with a 2 finger twist. I spent about 45 minutes fixing 5 vessels, not bad but don't think it should be up to me to finish the final manufacturing process.....
My airlock seems to leak its either the grommet or the lid seal any spare parts ?
Don E on Oct 25, 2015

We do have a few spare parts and we're happy to help figure it out. It's not clear from the brief message what part is at fault though. Could you contact us directly at brewmaster@northernbrewer.com and we'll see what you need

Gabe from NB
Since fermenting in a plastic bucket for 1+ months is not good... what about the plastic on this product? Is it recommended for extended fermenting... 2-3 months (like with the imperial stout)?
Ted B on Nov 28, 2016
BEST ANSWER: The HDPE plastic is denser than the plastic buckets are made with so this allows for longer aging without worries of oxidation like in a bucket. As long as it is sealed up tight 3 months should not be an issue. Making sure the container is full will also help.
What are it's dimensions?
C C on Sep 16, 2016
BEST ANSWER: The dimensions are 20 x 14 x 14 inches
Will these sit on a keg washer?
nf1er on May 18, 2016
BEST ANSWER: I'd think it would, as the opening is about the same size as the Big Mouth Carboys, and they can be washed with this unit. -Mike W,
How in the fu#k do you get the lid started so it it seals? I have tried this repeatedly and it never seems to seat correctly to get a seal that does not leak.
S D on Nov 28, 2015
BEST ANSWER: Hi, this seems to be a problem for a lot of people including me. There are a few ways to fix this. (1) If you have a batch going use blue painters tape around the edge of the lid. Easy to remove no messy glue. (2) When tank is empty place tank open side down on a flat surface and look for high spots and sand them down until flat. (3) Last get some food grade gasket material and make a thicker gasket. There is definitely an issue with sealing but it can be fixed. Have fun.
I've got my first batch in this now. It appears that my fermentation never started. So I repitched more yeast to try and jump start it again. It looks like there was some fermentation, given what looks like a yeast ring around the top but it still appears to have stopped really quickly. I see all the comments about the lid not being very airtight and I'm wondering if fermentation really did happen or not? My airlock has the humid-look that it normally does but it hasn't had a single bubble go through it, that I've seen. But I do go to work....... Any advice? Should I try pitching more yeast and attempt another tight seal? Thanks!
M O on Nov 4, 2015

Take a gravity reading. Sometimes a batch of yeast can be an overachiever. Do NOT pitch more yeast until you've taken gravity. It could be that while you were at work the yeast did its work. I've had this happen to me before.


Can I bottle the beer directly from the system, or do I still need to put the beer into a bottling bucket?
David S on Sep 15, 2015
BEST ANSWER: You can bottle directly from the fastferment. Be sure you have dumped all the sediment and stir in priming sugar solution. It has a 1/2" port and tubing so a standard 3/8" bottle filler will not work.
Will this fit in a standard refrigerator? The old style with the freezer on top. Mine has a shelf at the bottom that sticks out about 10".
