Description

The X1 Uni+ comes fully kitted out with the most advanced accessories available for the BrewBuilt Conical Fermenter. You'll have complete command of your fermentation with the ability to regulate temperature, monitor activity, harvest yeast, pull the clearest samples, and improve many more aspects of your overall fermentation process. The X1 Uni+ pairs the base model unit with a slew of upgrades, including a custom fitted CoolStix™ and insulating neoprene jacket, Flex Chamber Trub Separator & Yeast Harvester, and the Pressure Pack with Clear Float Technology.

Glycol-ready CoolStix™
Controlling fermentation temperature is one of the keys to brewing great beer. The CoolStix is an easy-to-use, innovative solution to achieve perfect fermentation temps. Pairs perfectly with an IceMaster Glycol Chiller or a BrewBuilt Chiller Pump Kit placed in ice water. Circulate cooling solution through the CoolStix to lower the temperature of your fermenting beer whenever needed. Unlike other in-solution cooling coils, the CoolStix utilizes a straight vertical design for the simplest cleaning and sanitizing process before and after use. The custom-sewn neoprene jacket will help keep your temperatures stable so you're not constantly cycling your submersible pump.

The 7- and 14-gallon models use a single rod CoolStix while the 27- and 42-gallon models use the CoolStix Reactor Rod with four cooling rods. The larger CoolStix Reactor Rod is made using a 4” TC fitting, so you will need to remove the Pressure Pack top to insert the Reactor Rod. After fermentation and cold aging are complete, you can replace the Reactor Rod with the Pressure Pack to sample and transfer under pressure.

Flex Chamber - Trub Separator & Yeast Harvester
The pressurizable Flex Chamber attaches directly to the butterfly dump valve and can be used for removing trub, harvesting yeast, and many other tasks. Since it's made from crystal clear Triton, you'll be able to visually monitor fermentation activity just as you would with a sight glass. Ball lock adapters can be attached to the threaded ports on either side, allowing you to connect oxygenation or carbonation stones, or flush the Flex Chamber with CO2 and use it to inject hops or other ingredients into your conical. Also a great option for storing yeast! Simply attach a 2" T.C. end cap or PRV and store your harvested yeast in the fridge for your next fermentation.

Pressure Pack with Clear Float Technology
Adding pressure capability will allow you to ferment, carbonate, and even serve all in one vessel. The Pressure Pack features the unique Clear Float Technology racking tube that can be used for taking samples, transferring to keg, or serving finished beer. This innovative feature draws beer from the top down, which means you’re always pulling the clearest, most sediment-free beer possible. Using pressure to draw a sample from the floating dip tube will also eliminate the tiny bit of oxygen that would be injected into your beer every time the traditional sample valve is opened.

Pressure transferring from fermenter to keg is the best way to protect your beer from oxygen when it’s at its most vulnerable state. Kegging could be considered the final hurdle in the brewing process, where limiting oxygen exposure is critical. This could mean the difference between your beer tasting great for months or tasting great for a week. Don’t take any chances. Use the Pressure Pack to keg from the top down and leave sediment behind.

X1 Uni Conical Fermenters
The BrewBuilt X1 Uni was born of thousands of hours of research, contemplation, and development. The engineers and critical minds behind its realization scoured years of feedback from home and professional brewers alike to determine the ideal feature set of a stainless steel conical fermenter. And where standard features fell short, we pushed the boundaries into new territory never before seen on a premium conical fermenter. The end result is a unit purpose-built to advance your fermentation process, improve the quality of your finished beer, and look good doing it. This is the brewing sidekick that you’ll brag to your friends about.

We guarantee that you will love the fit and finish of the X1 Uni Conical. Made entirely of 304 stainless steel, the quality exceeds what has previously been done in brewing applications and approaches the level of pharmaceutical-grade finish. With flawless welds and a dazzling mirror-polish finish inside and out, the BrewBuilt X1 Uni is easy to sanitize and even easier on the eyes. You’ll probably wanna snap a pic. #BrewBuilt

Extra Large 2” T.C. Dump Valve
Dry hop to your heart's desire. Try as they might, hopheads will have a hard time clogging this conical. With an oversized 2" bottom port, you’ll have all the clearance you need (and even more than some pro brewers) to drop out your dry hop additions with ease. The slick mirror-polish finish on the inside allows flocculating yeast to collect neatly at the bottom of the cone as they slide right down the smooth interior walls. The butterfly dump valve integrates perfectly with the included Flex Chamber Trub Separator and Yeast Harvester.

Reinforced Four-Leg Foundation
There’s a common complaint seen in the feedback for other conicals on the market—the tippiness of three-legged units. Three legs may be fine when the fermenter is sitting still on an even surface, but users are often forced to purchase a bracing shelf for more stability if they add casters or leg extensions. A conical is only as worthy as it’s foundation, so BrewBuilt modeled the X1 after professional-level brewery tanks with a four-leg, reinforced base. This seemingly small design feature is more expensive to produce, but it's what makes the X1 conical exceedingly stable when compared to other models.  When you fill up your fermenter with delicious fresh wort, you want to trust the vessel that’s holding your latest creation. Brewers shouted from the mountaintop that they wanted stronger, sturdier legs right out of the box that don’t require an additional bracing shelf. The four-leg, welded-bar reinforced system is absolutely rock solid. This is an especially critical feature if you plan to add rolling casters so can easily glide the fermenter around your brewery. 

The reinforced four-leg design not only increased the stability and strength of the conical, it also allowed us to extend it upwards, thereby eliminating the need for extensions in almost every situation. An elbow, a sight glass, or the Flex Chamber can be mounted under the unit with room to spare.

Handles Made for Handling
Although we don’t recommend lifting and moving a full conical, there may be times when you need to do so with the help of a friend. The beefy handles are built for it and won’t let you down. The handles feature molded silicone over stainless for a solid, comfortable grip, and are uniquely designed to stop half-way when they swing out so you won’t crush your fingers.

Adjustable Feet
The X1 Uni comes standard with thread-in adjustable feet. If your home brewery has uneven flooring, you can quickly and easily level out the fermenter. The feet can be swapped out with high-quality casters at any time.

Optional Upgrades

  • Pressure Fermentation Kit (Optional Kit is Requred to Ferment Under Pressure)
    The PRV that comes with the conical is not sufficient for fermentation as it can become clogged with Krausen. To ferment under pressure the Pressure Fermentation Kit is required. This kit includes a Ball Lock Spunding Valve and a professional 1 BAR tri-clamp PRV. The spunding valve features a 0-15 psi pressure gauge and a hand adjustable blowoff to dial in your desired pressure setting. The pro PRV provides added safety that is required when fermentingunder pressure. Also included is liquid Foam-Axe which helps reduce Krausen. Fermenting under pressure will reduce esters and fusel alcohol production, and enable you to ferment lagers at ale fermentation temperatures. Please read and follow all special instructions that come with the kit as well as your instruction manual.  

Other Features You’ll Love:

  • Downward-facing Blowoff U Barb prevents blow off tubing from kinking and is much easier to remove and clean than a fixed stainless blow off

How far below ambient will the coolstix hold beer? Will I be able to cold crash at 38F in my 110F garage with a glycol chiller?
Max Rudolph on Nov 23, 2020
BEST ANSWER: No, that difference is too extreme. The Coolstix can only be guaranteed to maintain fermentation temperatures. We will be posting temperatures curves soon.
Minimum batch size for each with the cooling package?
Derek Steckline on Nov 12, 2020
BEST ANSWER: We always recommend to fill your fermenter to the fullest to make the most of your time. That being said the cooling chips are mounted at about 75% of the volume of the fermenter, so that's pretty much the minimum for using that system.
What us the minimum amount of volume that can be fermented in a 14 gal. X1 Uni+ Conical Fermenter?
Richard Wellhouse on Nov 19, 2020
BEST ANSWER: The minimum amount we recommend is approximately 6 gallons. The thermowell is installed around the 6 gallon mark, and that will need to be covered to ensure that you can read your fermentation temperature and use a temperature controller if you wish. If you can only brew 5 gallons at a time you can brew the wort a little bit concentrated in gravity and bitterness then dilute the wort in the fermenter with a gallon or two of distilled water.
Is there a good heating option for these? It seems most of the energy went to cooling the temps rather than raising them.
Cole Christian on Feb 8, 2021
BEST ANSWER: The FermWrap (fe650) taped on the cone and a Ranco temperature controller (FE601) is a simple option for heating the X1. The included thermowell fits the probe from the Ranco thermowell allowing you to heat and maintain temps within one degree.

What about CIP?
Valued C on Nov 23, 2020
BEST ANSWER: For CIP we recommend using a spray ball such as our CE29 which fits the 1.5" TC on top of the pressure pack lid. It has 1/2" tubing which can easily be adapted to TC or use any of our stainless fittings in that size. Especially for larger models we recommend using a powerful pump that can create 29 psi.
How to get a spare lid gasket? I have the 7 gal X1 Uni+
Bill Brennan on Oct 16, 2021
BEST ANSWER: At this time we do not have stock of spare lid gaskets. We will do our best to get those in stock as soon as possible. We apologize for any inconvenience.

Could be 5 star...
First off, I am new to home brewing so every step along the way has been on a steep learning curve. I have had issues with my two units which I will explain. Other than one issue, the fit and finish is awesome! I really want to LOVE the X1! The four legs are rock solid. Ok, when full, the center of gravity is up there so be careful rolling it around.

For my first brew I discovered the the PRV was leaking. I never could see bubbles in the blow off jug. There were a number of calls/emails with MoreBeer. I swapped the parts from the 2nd unit with no change. MoreBeer sent me new springs just in case the ones I had were not right. With new springs it still leaked. I would burp the X1 with a little CO2 daily as it was something that I could do. The PRV housing is welded to the lid. That is a poor design IMHO. Again, more emails and calls with different customer reps. They are all great to talk to but not all have the information about the problem with the lids. I was told that new lids are on the way but I haven't heard anything in awhile. So this UNI is not useable. After doing a good scrubbing after the brew, my fingernail caught on a burr of some sort down in the concical. As I am willing to fix it, MoreBeer gave me credit. This saved them from having to ship a new unit. Although with the lid issue, I probably should have gone that way. I don't know how long I will have to wait for a new lid.

The butterfly valve leaked on the second one with only a little water in it. MoreBeer was awesome and got a new valve on the way. It has a plastic handle but that is ok. The PRV on this unit would not release at 15 psi. When I did a pressure test. In fact, the gauge was climbing to 20 psi. Oh boy. The sample valve was a bit hard to close all the way. After pulling it apart, there was something on the valve body seat. It was a small piece of SS that probably came from the machining process. I carefully removed it but I noticed the white end of the valve handle had some scratches on it. It held for my second brew. To be safe, MoreBeer sent me a new one. This UNI is all sanitized and ready to go again. The lid gasket installation takes a bit of getting used to. I heard they cost around $100 so be careful with it.

I guess I didn't have the float pickup hose on the pressure pack lid as it fell off as I was filling. With the PRV leaking, I wasn't able to use it anyway. For the second unit, I had my keg on a scale and figured out that there must have been 2 gallons left when CO2 began to vent. The hose is way too long. After a web search, I saw where a guy had the same problem and shortened it by 10" or so. During my cleaning process, I tried various lengths so that the ball rests deep in the conical with the hose still in liquid. If I have more problems with it I will just go with a rotating racking arm.

The Fermwrap that was recommended does not fit the 7 gallon Uni. From another X1 review, I found the Delta Brewing Systems wrap fit nicely underneath the jacket. It also works pretty well too!

The jury is still out on the usefulness of the Flex Chamber. So far it has been a pain....I will probably get a 90 degree elbow.

I got casters way cheaper on Amazon.

I wish there was a little more clearance to connect ball lock disconnects on the pressure pack lid. It is a tight fit. I do have the TC clamp in the best position. In a 68 F room, the IceMaster 2Max was only able to get the beer down to about 40 F. I will make some jackets out of foam sleeping bag pads and see how that works. I did make bubble foam insulation pads that fit easily on the lid to help when using the heater.

I have spent a lot of time with these two units. It is a good thing that I am retired and have the time. If was working 40-50 hours a week like I used to, there would been a lot of late frustrating nights.

My fingers are crossed for a new lid so I can have two brews fermenting at one time.

In hind sight, I should have just gone with the basic model and upgraded it with what was needed.

Great Fermenter - 7Gallon
It’s a great fermenter, great weld quality and amazing surface finish.
It is more sturdy than the other stainless fermenter I own. Especially the handles are more sturdy and you can actually move the fermenter when it’s full.
It could be a little wider, to increase the space between the legs, but other than that, I couldn’t be happier

Flex chamber is worthless.
I wanted to wait until I had sufficient usage before writing a review. First let me start with saying I do like this uni tank however there are some major issues I've experienced along the way first and fore most the plastic "flex chamber" is the worst part about this entire product. The plastic gets sticky and doesn't allow you to unscrew without some INSANE Force. I have to use a ruber oil filter strap and and hear the stress being put on the plastic. I'm not able to do this with liquid in the ferment. Unless there is something that I'm seriously doing wrong this part of the product is completely worthless. (If there is a fix for this from the manufacturer please let me know) Secondly I had an issue with the dip tube floating above the top of the liquid line and had to add a stainless steel lock washer that would hold the end of tube under the liquid. The last issue I had was with the clamping system for the top lid is just kind of a crude design and for the money I would liked to have seen a better design for the clamp. Would I recommend this unit? Not sure, mainly because of the flex chamber, so maybe buy the unit without it or just plan to not use it. ( Brew built , if you read this and have a fix for this please let me know)

Missing Part
I received my Brewbuilt X1-Uni+ today. I was really excited as I unpacked and started to put it together. I am really impressed with the quality until I got ready to put the lid on. The gasket is a bit larger then the rim and you have to work with it to get it to fit in the groove then I found I was missing the lid clamp making the fermenter useless. I was hoping to use it this weekend but it looks like I will be using my old reliable plastic one. I am hoping they can send me a replacement clamp instead of having to tear the fermenter all apart and return it.

Killer conical!
This 14 gallon conical is impressive AF, from the near mirror finish of the metal to the practically seamless joint welds. In addition to that, the valves are easy to use and the whole setup nearly falls together. I'm a long time Blichmann conical owner, anyone who complains about the setup or quality clearly hasnt struggled with some of the eccentricities of any other conical. I have a walkin cooler so I heat this with a fermwrap and inkbird - works well. There are 3 things that deserve attention: 1) the basic model doesnt let you isolate the system easily (pressurization) because of the blow off port - I would advise adding a butterfly valve to this, 2) the complete versatility of this conical is the pressurization, beer transfer off of the surface, and fermentation under pressure. Because of this, I would recommend the kit that allows pressurized transfer and a spunding valve. 3) the ca.1/3 gallon yeast capture system is a must buy for yeast reuse but 'as advertised' as it doubles as a 'trub dump' is a joke since after cooling I have 1-1.5 gallons of trub from a 14 gallon batch. The adaptor that fits from a 2L soda bottle to a quick disconnect should come standard but it doesnt, so buy it for $10 and solve this probelm. Overall, this is a killer conical and within a batch or 2, you will learn the system and use it like a pro.

Just about everything you will need!
The decision to order the Brew Built X1 Uni+ 14g over other uni tanks, was how fast the unit would be delivered. I did my research, counted the pros and cons, finally just decided to pull the trigger. Simple instructions, and easy to set up. Did the water test to get familiar with its features.

First brew day we chose to really see what X1 uni+ paired with the Brew Built ice Max 4 could do. We chilled the lager 68 and got the glycol running. We were ready to pitch within 3 hours. The CoolStix sent with X1 is larger then the regular CoolStix’s I’ve purchased earlier for other fermenters. The X1 uni+ probably has more features I would ever really need, but only time will tell. One batch in and so far so good. Very excited to test the clear float for transfer. I will be ordering a CIP ball to make cleaning and sanitizing easier.

My only doubt / concern is if the CoolStick will be able drop the beer to 33 deg to carbonate. Not that that is a deal breaker, but when it’s promoted as a feature, I would like to use it. Like I said earlier, only time will tell.

All and all, I am very pleased with my purchase,

Happy brewer
I have the 14 gal system. So far all good. I'm fermenting my first batch in this: 6.5gal of a Belgian golden strong ale. So far, it's working wonderfully. I won't be pressure fermenting or self-carbing this brew, so I'll need time to test that, but for now, this is working well.

I definitely recommend getting the casters; it makes moving it so much easier.

After using the Anvil and brewzilla fermentors I was looking for something way more sturdy. This thing fits the bill. Everything is metal and there’s so many features. I didn’t have any issues with the handle hitting the leg, it just needs to be installed correctly. I bought another one as soon as I saw it.

Really wanted to love this piece
Was very excited to receive my new fermenter from BrewBuilt, have the chiller to match. Got it today and took it out of the box. It's packaged very well. Some random bits of garbage in the box.. balls of tape, zip tie ends, whatever. Welds look nice, good polish on the metal. Inside etching is good. Pull everything out, start to handle the valves and clamps. Sample valve has sharp unfinished edges on the knob, tanks sits on hard plastic feet which didn't even thread into the legs straight. Tri-clamps look alright. The massive butterfly valve can't be installed straight or operated smoothly because it hits the legs. For price paid, not very happy with the quality. Should have rubber feet, at the very least. Coolstix sounds like it's one long tube and one short tube banging around inside, not sure what the operational theory is on that. Not can't speak for where this or other accessories are made but I wouldn't put my name on that workmanship, especially at $800.
Handle hits the leg brace.
Butterfly valve needs to be rotated in order to open or close, handle is too long.
Rough edge on the polished face. Inside edge is beveled nicely.

Response from MoreFlavor
Thank you for the feedback. Great to hear that you are satisfied with the quality of the cone, welds and finish. The Coolstix is a tube-in-tube cooling apparatus and the sound you hear is the inner tube within the Coolstix. The butterfly valve is over built and the same size on all models. We agree its a bit oversized on the 7 gallon. If you install the valve the other way, so that the handle goes up, it does allow for more adjustability. I do see we sent you out a different style of butterfly valve we have in stock so hopefully that is also a good solution. We did talk with the product designers and a small butterfly valve for the 7 gallon unit is being designed.
