About this project
The OneDerBrew™ is a device that can be used to turn any bar into a Microbrewery at a fraction of the current cost. What it is, is a 1/6th barrel keg that is converted into a Uni-tank for fermenting beer. A uni-tank is the preferred method for fermenting as all the sedimentation settles in at the bottom of the cone (60-70 degrees) for easy removal . The OneDerBrew™ unit ferments, clarifies and carbonates all at once, it ferments under pressure which allows for quicker fermentation which makes the beer better faster than fermenting without pressure. There is a port at the bottom of the keg that would allow for sampling the beer as it ferments,without possibility of contamination so that the the attendant can know when the beer is complete. After fermentation is complete, the complete unit can be moved to the beer dispensing fridge and connected to a tap just like they would any other beer keg.
Typically the cost of a Microbrewery can easily run into the hundreds of thousands of dollars. With the OneDerBrew™ the cost is down to the license ($1,050 in IL) and then how many units you want to buy, We have found there is a lot of interest from bars for putting these units into their establishment to create a Brew Pub or Microbrewery.
We are taking an ordinary 1/6th barrel and modifying it to fit a cone to become a pressurized uni-tank. After the beer is brewed (cooked) it is cooled and then transferred to the unit, yeast is added and the unit is closed up. It can then be wall mounted or placed on a shelf or counter while it ferments until ready, which can be as little as one week.
Other fermenters on the market either don't hold pressure, or are unable to hold enough pressure that allows beer to carbonate while fermenting. It always has to be transferred to a keg or bottles. This unit is also has the benefits of having a stainless fermenter but also, the plastic cone allows for seeing the beer as it ferments. This way it is easy to tell how much yeast has fallen out, and also when it is done clarifying.
Also if you chose, since it is pressurized and carbonated you can chill the unit, then have it out in the open, and serve directly from the OneDerBrew™.
This item isn't only for Microbreweries, home brewers can use it too. It can be used just like a Microbrewery would, or it can be used as a fermenter and transfer it to a Corny Keg if you already have a Kegerator set up.
Steve's OneDerBrew™ Story
My interest in home-brewing came about around 2000 when some friends of mine sparked my interest in brewing my own beer. First time going through the entire process I found myself with a brew I was not satisfied with and it did not taste good. Second time going through, about 20 days in, my nephew knocked over the carboy, containing this brew's second fermentation, with it ending up all over the floor. With all that work it brought me to question why you could not ferment and carbonate in one step. Thus my quest that lead me to the OneDerBrew™.
I set out first to read as many books as I could get my hands on and question some home-brewing experts. These experts included authors such as Dave Miller, Charlie Papazian, and Al Korzonas. My question was about being able to make beer all in one step, fermenting along with carbonation. Being a Bio Medical Engineer I also conferred with Dean Marshall, an engineering scientist. With a lot of consulting and research of what I had conceived could be, that fermenting and carbonating could be done at the same time, came to be possible. Thus came the first OneDerBrew prototype.
This first prototype was made from two polycarbonate containers that I welded together. I brewed the beer in this new container in the microwave. Then transferred the beer to a freezer to chill it to pitching temperature. After that, pitched the yeast and closed the container with a pressure gauge plus a pressure regulator attached. When a couple of hours had passed, it started to build pressure and I then adjusted the pressure regulator to maintain 15psi. I then allowed the beer to ferment for a week. After a week we tapped the beer and tasted it, and it tasted great.
Because of this success I began the work of the first version of the OneDerBrew™. This was designed to brew one gallon of beer in the microwave, then ferment, extract yeast, clarify and carbonate. After chilling the unit in a refrigerator the beer would be ready for serving. We made hundreds batches of beer and soda in this. Approximately one thousand units were sold online and at shows. We had a lot of satisfied customers. However a bigger 5 gallon version was requested. As a result the second version of the OneDerBrew™ was developed.
Our second version of the OneDerBrew™ coupled a standard 5 gallon bucket with a 60 degree conical cone. This version we did not brew in the container, but still fermented, carbonated, and could be served out of it. This version was displayed at the 2012 AHA, American Homebrewers Association, Conference in Seattle Washington. Many home-brewers and experts, such as Charlie Papazian, John Palmer, Chris White from White Labs, were impressed.
September 2012 we released this second OneDerBrew™ to the public, and we have sold approximately 2000 units. Even though the OneDerBrew™ is a completely new way of home brewing, instructors are starting to teach using this simplified method.
In December of 2013 we ran a Kickstarter campaign to raise money for an all-in-one unit, that brewed and chilled the beer, along with everything else this version does. We ultimately didn't reach our goal, but at the same time, found out there was interest to put them in bars, and they didn't need the brewing or chilling aspect so we decided to drop those, and change the Corny Keg to a 1/6th barrel that most bars use.
How This Version Differs
This version of the OneDerBrew™ is similar to our 2nd Generation OneDerBrew™, with 2 main differences. The 1st difference is that the holding "tank" is no longer a plastic bucket, and will now be a normal 1/6th barrel, stainless steel keg that is very common among bars, this also eliminates the "weak" link in terms of the unit. The plastic bucket isn't really designed to hold pressure, it can but it's possible the lip of the bucket could fail and develop a leak. The 2nd difference, while it is still a great item for home-brewers out there, this version will be marketed more towards bars that want to become Micro-breweries. This is why we decided to go with the 1/6th barrel keg instead of a normal Corny keg that home-brewers use.
As for the 3rd generation OneDerBrew™ that was previously on Kickstarter, we decided to delay the heating and cooling units. This will eliminate much of the cost in the unit, and make it more affordable to home-brewers and this configuration makes much more sense in a Microbrewery set up.
HOW WE GOT TO WHERE WE ARE NOW
The second version of the OneDerBrew™ was appreciated and liked because it was an affordable conical fermentor that could hold pressure, carbonate, ferment, clarify and serve after refrigeration. However, there was a desire for a stainless steel design. Problem is most stainless steel conical fermentors can not hold the pressure necessary to carbonate and yeast is not visible to determine when it should be removed . It became clear to us that a stainless steel keg (industry's standard pressurizable beverage container,) coupled to a clear conical base could make a fermentor that could hold carbonation pressures. Along with holding pressure the clear conical base would allow the brewer to see the yeast accumulating. Using a 1/6th barrel keg that bars are already accustomed to allows them to easily convert over to becoming a micro-brewery.
After attempting to raise money for a unit that cooks the wort, and also acts as a chiller once it is done fermenting, from our feedback we have decided there is more interest on the commercial end of the unit, and not make a unit that does everything. Because of this feedback we decided to put the 3rd generation full unit on the back burner for the time being, and create a unit that can go to bars and be shown in a Micro-Brew type setting. We wanted to make this easy and affordable for a bar to turn into a micro-brewery, being that it is only 5 gallons, a bar might want to have multiple units, to cover possible large demand, and also have different types of beer available. The heating and cooling elements were removed since they were the largest cost involved. Also a bar doesn't need a cooling system since they have large coolers for their beer.
WHO WE ARE, QUEST APPLIED TECHNOLOGIES
We here at Quest Applied Technologies, the creators and home of the OneDerBrew™, are a design, development, and manufacturing company. Because of this we are capable of delivering a high quality product. With 30 years of experience we have delivered over 5000 products world wide.
Design, mold construction, injection molding of plastic parts, modifying of the Corny Kegs, and assembly will all be done in house. The heating and cooling components are out sourced from local companies. Creating and delivering high quality products is a passion ours here at Quest Applied Technologies.
Current status of development
If funded, the money will go towards the raw material (aluminum) for making the molds. For this latest version of the OneDerBrew™ we are taking a previous cone mold we had in house, and making slight modifications it to work with the keg.The cone will have standardized 3/4 NPT holes, so it is possible to easily get fittings. These modifications are going to be started soon (Mid February-Early March). The remaining components (Legs, stand, Pressure relief, possibly gasket) will all be started once the project has been funded. These are all smaller items, and won't take very long to create (around 2-3 weeks each).
For cutting the hole in the bottom of the keg, we are using a 6 5/8" hole saw that can be picked up at a local hardware store.
Risks and challenges
There isn't a lot of challenges with this new version, we already have a cone mold made, it just needs a couple minor adjustments. We do need to make molds for the attachments and legs, but those are smaller, simpler molds. Prototypes of this version have been tested and are fully functional.Learn about accountability on Kickstarter
