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.

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.

Waste of Money
Great idea, but poor execution. I bought two of them. First batches were great. Third batch was terrible. I chocked that up to using hops my friend grew and I thought maybe there was some kind of bacteria on them that ruined the beer. Brewed two more beers and both were bad. I cleaned both of them and when my wife was moving them she says to me that they stink. As it turns out, the ball valve collects yeast and other goodies, like mold. You clean through the valve, but not the against the walls on the inside. It is five large pieces and then a few washers to take them apart and clean everything. I cannot tell you how gross it was. This does not make things easier with "80% less cleaning." Washing a bucket and a racking cane is so much easier. Or do what I did, put a valve on each bucket and just use a hose. That is truly less to clean. And a lot less complicated. I would not recommend these to anyone. They also take up a lot more space when being stored.

My old carboys are getting dusty!
I bought my first one right when they came out and I loved it. I now own 3 of them and if I had more room for them I'd buy more. It makes transferring to secondaries to remove sediment unnecessary, just remove the collection ball after fermentation your done. No more cleaning/sanitizing new carboys, siphons, ect. once you put in your wort and yeast you don't need to mess with it until it's ready to bottle/keg. It also gives you the ability harvest yeast.

Feel like a pro now
The product works exactly as advertised. I got the thermometer and thermowell, as well as the stand. All the yeast settled in the collection ball. There was still some more at the bottom of the cone of the fermenter, but it all went down into the collection ball when I emptied it out and put a clean one on. The hole at the top is nice and large for cleaning or dryhopping. It also comes with a 1/2 inch barb for bottling and a tube. I used a nylon tube connected to my existing bottling wand and it worked perfectly. Again, I just added the priming sugar to the fermenter, stirred a little and bottled right out. Since the hole is at the bottom, I was able to use all the beer. The unit comes with teflon tape for all the threads. I highly recommend using a liberal amount of teflon tape to prevent leaks. Only issue I can think of is how to use a heating blanket around it, since those were made for cylindrical fermenters.

Thw big little success.
After three fermentations in it it has met my expectations 95%. The only things I would recommend as an item for the producers backlog is to make the trub-ball twice it's current size, around 500ml bigger. The yeast is always reaching up into the conical and reaches the 500ml mark. Another thing is that unscrewing the lid after two weeks in fermentation is quite hard sometimes. It is slippery when you are not using the wallmount. I use the floorstand and these are my only complaints. Not to hard to meet in future updates of the product.

FastFerment Conical Fermenter
Finally used my FastFerment two weeks ago to brew a batch of beer and this thing is just fantastic! The product worked exactly as advertised and I had absolutely no problems at all and will happily get rid of my carboys and never use them again. I would tell anyone that is on the fence about this product to buy it and they will not be disappointed.

So nice and simple
Just bottled first batch of hard cider thru this and wow how nice and simple. Less mess. Easy to clean. Only complaint is size 7.9 gallons doesn't coincide with yeast batch sizing of 5 gallons but I'm a big fan. BUY ONE NOW!!!

So Much Easier!
I didn't realize how much time & energy this would save, but it does! Not having to clean & sanitize carboys, siphons, etc.. for racking to secondary is great. Also, not introducing oxygen into the beer during transfer to secondary makes for a better product. Other pros include a container that's easy to clean, and keg/bottle from. The included mounting racks work great and are easy to mount to wall studs. I haven't harvested yeast yet, but what a great concept. The height of the FastFerment is taller than a traditional carboy so keep that in mind for the initial transfer from kettle to FastFerment.

Very easy - Great product
I had never brewed before buying the FastFerment but after 3 batches of wine and 2 batches of beer I can say that this thing has got me excited to keep going. The FastFerment really makes it easy to succeed at making a great beer/wine because of the very fact that you do so little and have such little contact with the product as it's fermenting. I have two now and have had no issues with leaks. I followed their direction for the application of teflon tape, I think around 6-8 wraps, and they've been sealed tight ever since.
One thing to note is that because of the nature of ball valves, when the union valve (ball valve) is OPEN a small quantity of air (or beer) remains trapped in the housing of the valve unit itself. This can lead to sanitization issues if it is not cleaned out after each batch. To clean it just turn the valve on a 45 degree angle, or half open. Water will still drain through from the body of the fermenter out the bottom but it will ALSO wash the compartment that stores the liquid then the valve is completely open. On a simialr vein, if you store your FastFerment for any period of time make sure the valve is half open so air can circulate through all components of the valve. You can visually see the compartment I'm talking about by eyeing down the valve while opening and closing it. I would not consider this a design flaw and chances are you'll be fine either way, but as they say... The More You Know***
At the end of the day I highly recommend this to anybody, newbies or not.

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
Haven't see this asked yet. Look like a nightmare to clean. How is it cleaned?
I don't think this actually eliminates the secondary. With the secondary, yeast activity is complete stopped. I don't see this happening with this device. When I brew, my airlock is always active in the primary and always inactive in the secondary.
D U on Jun 22, 2016
BEST ANSWER: Pretty easy to clean. The top opening is large enough to reach all the way in and scrub all of the inside surfaces. It�?s even big enough to drop the collection bulb in, so I typically drop the bulb and all of the tubes in to let them soak in the cleaner and then the sani.
For the secondary, it is essentially limiting the surface exposure/surface area of your wert to the sediment by collecting it in the bulb. For batches with a lot of sediment, you can remove the initial full bulb, empty it, then attach it again so that it collects more sediment. I have stopped transferring to a secondary, and had no problems. The yeast goes dormant after the first few days either way. After that the airlock activity stops whether you leave it in the original container or move it to a secondary. Transferring to a secondary is only to get it off of the sediment.
I�?ve been very happy with the design of the FastFement. The only problem I have had is that the lid is very difficult to remove, and sometimes hard to get a good seal with.
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.
J J 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!


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 ?

What are it's dimensions?
C C on Sep 16, 2016
BEST ANSWER: The dimensions are 20 x 14 x 14 inches
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: I would recommend leaving the valve open with the collection ball attached during primary fermentation. This will allow the ball to fill with trub and yeast gradually during the fermentation. Then you can close the valve and remove the ball with ease.
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.
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: The amount of oxygen introduced when putting the collection ball back to collect yeast is minuscule compared to oxygen exposure when racking to secondary in the usual way considering the large exposed surface area.
I have brewed 203 beers - the last 10 using the fast ferment. I love it. At the of each batch I take the FF totally apart and clean it. On the next brew day I assemble the FF and fill it full of sanitizer while I brew. I keep everything very clean through primary and secondary fermentation. I bottle from the FF after sanitizing the attachments. Problem: At least 50% of my FF brews have developed a gushing disease in the bottle. (Yes I'm very careful with sanitizing bottles too). I have reluctantly gone back to the much more labor intensive glass carboys - and the problem is gone. Any thoughts?
