Standard Shipping Rates Apply to this product

Eliminate 80% of sanitizing and cleaning with this affordable all-in-one conical fermentor. Conduct all stages of fermentation in this single vessel. Remove the trub from the bottom of the fermentor instead of transferring all your liquid to secondary. No siphons, no secondary fermenting vessel to sanitize, no extra bungs and airlocks.

FastFerment produces dramatically better results. Start each batch by letting debris settle out into the collection ball before pitching your yeast! Remove the debris, and pitch into ultra-clear wort. Plus, FastFerment minimizes the risk of oxidation and contamination by eliminating the need to transfer to a second vessel, preventing off-flavors and infection. Keep your batch safe from external spoiling factors by keeping it in one place.

Perfect for making beer, wine, or cider.

Love my fermentor!
I have added a sample port and have had trouble sealing the lid.. But i am a diy sort of brewer. Overall i absolutely love it. Currently i wrap the top threads with saran wrap to seal it properly. The bubbles are a big indicator of whats going on inside, very important. I may buy another one soon!

A novice’s perspective
I went from a one bucket system without secondary to this very early on in my brewing life. For a novice, it works very well. Getting it together without leaking was a bit tricky for me but I used a ton of plumbers tape and haven’t had to replace any yet. I put some design flaws below but also wanted to note that I had an issue with a Belgian in this fermenter because when transitioning from primary to secondary (which is SUPER EASY to do) there was a backup of sediment and the beer wouldn’t drop into the ball. I ended up having to stick a tube down and try to unjam it but I screwed that up and long story short beer wasn’t any good. You live you learn I guess (think I may hav over oxygenated it).

Design flaws:
- When you turn to get the bottom off to either keg/bottle it or transition it to secondary sometimes the connector turns with it which if you’re not paying attention can be a big problem. Luckily this hasn’t happened to me yet.
- The logo pops out of the fermentor and leaves it vulnerable to bacteria since it gives them a place to hide. You just need to be sure to scrub it.

Other than that it’s pretty good. If I had to do it again I’d probably opt for the catalyst fermenter since the opening is larger but this not a bad choice. If you’re still figuring things out at home I think this is a good choice

Great value
Used my fastferment for the the first time. Easy set up if your patient, looking forward to dumping the trub and not having to siphon.

Good idea, poorly constructed product.
The FastFermenter is based on a solid idea and is almost awesome, but the terrible quality of this product makes fermentation a frustrating endeavor. In short, it leaks, and yes, I read and re-read the instructions. I used copious amounts of correctly applied Teflon tape. The molding has several prominent seam lines that extend through the threads. I spent the better part of an afternoon cleaning, filling, and sanding the grooves on the threads in an attempt to get rid of the molding seams in the plastic. If I re-apply literally 7-10 layers of Teflon on the threads it will usually not leak too badly. There is still a small puddle on the ground under the FastFermenter in the morning after my brew date, and a sticky mess to clean up. Dang, it was, and still is, frustrating.

Fermentation trouble
initially had trouble with fermentation - used Omega yeast slurry and hadn't fermented yet for 3 days. Closed the valve and poured the trappings back into the beer. Day later had active fermentation. My suspicion is the yeast slurry sunk into the collection ball?

Not off to a great start, but excited to see the results. And my teflon tape skills are now expert level.

Great for the money.
Some people have complained about the gasket. GET SOME FOOD GRADE LUBE. The o-ring in the lid needs to be lubed between uses. And don't over tighten it. The ball valve has never clogged on us. We leave it open (with the collection vessel on it) while fermenting and after a few days we close it and dump it and put it back on and open the valve back up. We have put over a 100 gallons through it and the only thing we ever had an issue with was the lid gasket. Lubed it and never had a problem again. It is a little awkward to handle but without the ball on the bottom you can set it in a igloo water cooler (our mash tun) and then you have handles to pick it up with and hang it then remove the cooler and put the ball on. I wish we had a few more.
November 8, 2017
This fermenter is great in theory but awkward to work with because of its top heavy design. It lacks stability on the optional base ($29) and even moves quite a bit with wall mount brackets included.
My biggest issue is the screw on top always feels as if its cross threaded and doesn't always form a tight seal without a lot of effort.
This unit also has a lot of connecting parts making set up, break down, and sanitizing a bit more challenging.
I love the concept but don't recommend the product at all.

Timesaver and easy to handle. Have 2 of them now. Only recommendation would have been making the neck wider between collection ball and main body.

Great, when you apply some attention to detail.
I ordered one about a year ago and it's been great. Since then they have upgraded the top seal to a silicone gasket that's round
(ORIGINAL was flat) it make it that much better. I can not stress to you enough when it comes to cleaning, they say you don't have to take apart the ball valve to clean it. DO IT ANYWAY. When it comes to taping the threads with the white thread tape, wrap it a minimum of 10 times. MINIMUM. I wrap them to the point I see little rounded edges on the threads. You may not think so, but 5-7 gal of liquid has alot of pressure. Lastly, take the time and fill it with water to the 7gal mark, have the ball valve open and let it sit for 24 hrs and check for leaks. You've spent all this money, don't waste your wonderful booze because the fermenter leaked or went bad(didn't clean that valve like I said). Cheers! P.S. I make wine in mine.
Love these fermenters. Especially since they upgraded the top seal.

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 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: Just leave the valve open and allow the yeast to collect into the ball container
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.....

What bottle filler will fit the bottling hose that comes with this fermentor?
A shopper on Jan 1, 2018
BEST ANSWER: 1/2 inch
1/2" Bottle Filler (15" length)
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: I does. Has everything you need unless you plan to not attach it to a wall then you'll need a stand but other than that it's all included
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.
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.
Has anyone thought about or tried to refill the collection ball from the sampling port after a trub or yeast dump to void introducing oxygen into the vessel?
A shopper on Jan 14, 2018
BEST ANSWER: No way to do that. I have flooded the ball with CO2 before reattaching though. If you are worried about O2 just don’t open the valve again after dumping the grub. I don’t think it’s necessary to worry though. Nowadays I just let it rise right out the blow off tube.
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.
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.
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!
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.
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!


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

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,

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".
