We're excited to announce the coming release of the BrewBuilt X1 Uni Pro Conical Fermenter! The 7 & 14 gallon are now available. The 27 gal size is still in development with an expected release of Summer 2021.

The X1 Uni Pro is the most advanced homebrewing conical on the market, featuring Peltier technology to maintain fermentation temperatures with the highest level of precision. This completely self-contained conical fermenter doesn't require the additional space or expense of a dedicated refrigerator or glycol chiller and is exceedingly simple to configure and operate.

Peltier Technology
First discovered by Jean Charles Athanase Peltier in 1834, the "Peltier Effect" occurs when an electric current runs through a circuit of dissimilar conducting metals. This thermoelectric reaction that happens when the current passes from one metal to the other can produce either cold or heat depending on the direction the current is flowing. It wasn't until NASA began using this technology that it started to gain widespread use. Today, Peltier chips are commonly used in a variety of applications such as cooling computers and small refrigerators. BrewBuilt saw how this could be used for brewing applications, and they've been raising their glass to Jean Peltier ever since.

Precision Temperature Control
The X1 Uni Pro maintains fermentation temperatures using localized heating and cooling distribution. Peltier technology provides the cooling near the top of the conical where temperatures are hottest, and a very low watt density heating pad placed inside the neoprene jacket gently warms the unit from the bottom up. Cooling and heating are automatically turned on as needed via a stainless steel control box that can be mounted to your wall or hung from one of our custom-welded stands. Simply program your desired set point on the controller and sleep easy knowing the X1 Pro will keep your fermentation temp on target to within 1 degree of the set point. The X1 Pro's ability to provide both cooling and heating means your fermentation will maintain the perfect temperature from beginning to end, providing cooling during the vigorous active fermentation phase, and providing heat to maintain the set temp when yeast activity ramps down. Note: We employ a very low watt density heater to protect your beer from the off flavors that can be created by heating the settled yeast at the end of fermentation. We will be releasing a stronger heater in Fall 2021 for rapidly changing temperatures.
The custom-sewn jacket features dual-layer insulation, with an inner layer of closed-cell, fiber-free elastomeric thermal insulation and an additional layer of durable neoprene. This allows for exceptional cooling and heating efficiency, enabling the X1 Pro to maintain fermentation temperatures at up to 30°F below ambient temperature. The X1 Pro models will easily maintain ale temperatures in 80°F environment and lager temperatures in a 70°F environment. Note that this is for fermentation temperatures and that the differential you can achieve goes down as the ambient temperature goes down.
Flex Chamber - Trub Separator & Yeast Harvester
The Flex Chamber attaches directly to the dump valve and can be used for monitoring fermentation activity, dropping trub, harvesting yeast, and many other tasks. Ball lock adapters can be attached to the threaded ports on either side, allowing you to connect oxygenation or carbonation stones. Or flush the pressurizable Flex Chamber with CO2 and use it to inject hops and other additions into the fermenter. Also works well as storage vessel for harvested yeast!

Pressure Pack with Clear Float Technology
Add pressure capability with the Pressure Pack upgrade. With a pressurizable conical, you can ferment, carbonate, and serve all in one vessel. The Clear Float Technology racking tube can be used for taking samples, transferring to keg, or serving finished beer. This innovative feature draws liquid from the top down so you’re always pulling the clearest, most sediment-free beer possible. Using pressure to draw a sample also eliminates the small amount of oxygen that would otherwise be injected into your beer when using the plunger-style sample valve.

Protect your beer when it's most vulnerable by pressure transferring from fermenter to keg. Kegging is the last step where you could potentially damage your beer via oxygen exposure. With the Pressure Pack you can keg from the top down and leave sediment behind.

X1 Uni Conical Fermenters
The BrewBuilt X1 Uni was purpose-built with today's brewers and modern brewing processes in mind. The end result of thousands of hours of research, contemplation, and development, this conical fermenter boasts a feature set that will advance your fermentation process, improve the quality of your finished beer, and look absolutely stunning while doing it. 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 all the premium features brewers demand, and a list of available upgrades, the X1 Uni will be your favorite piece of brewing equipment for many years to come.

2” T.C. Dump Valve
With an oversized 2" bottom port, you can dry hop worry-free. Many conicals can run into clogging issues with a standard 1.5" dump valve, but BrewBuilt designed the X1 Uni with hop lovers in mind. Flocculating yeast will slide right down the smooth interior walls, collecting neatly in the bottom of the cone to make yeast harvesting and removal a breeze. And the butterfly dump valve will integrate perfectly with the included Flex Chamber Trub Separator and Yeast Harvester.

Reinforced Foundation
Many homebrew conicals on the market receive a common complaint, and that's the tippiness that comes with a three-legged design. This design is mostly fine when the unit is set on an even surface, but it also results in users needing to purchase a bracing shelf if they ever upgrade to rolling casters or add leg extensions. The X1 Uni features a four-leg, welded-bar reinforced base modeled after professional brewery tanks. Although it's more expensive to make them this way, the cost is well worth it, as this seemingly small detail provides an absolutely rock-solid foundation. This is a critical feature for those planning on adding rolling casters. The reinforced legs also allowed the conical to stand taller, so there's no need for additional leg extenders. Mount an elbow, a sight glass, or the Flex Chamber underneath the dump valve and still have room to spare.

Adjustable Feet
The standard thread-in feet allow you to adjust the stance of the conical to compensate for uneven flooring. Quickly and easily adjust the fermenter if your home brewery isn't completely level. The feet can be swapped out with our high-quality casters at any time.

Volume to Reach Sample Valve 0.2 gal 0.43 gal 0.92 gal 0.92 gal

Recommended minimum batch size is based on the volume needed to submerge the thermowell, allowing you to use a temperature controller to maintain fermentation temps.


Temperature Specs:

80°F -24°F -27°F -30°F
90°F -26°F -29°F -32°F

The above chart represents the maximum drop in temperature you can expect based on the ambient temperature. For example, with the 7-gallon model in a 60°F environment, the lowest temperature you can expect to acheive is 42°F or 18°F less than ambient. Full temperature drop my take 36 to 48 hours.
