Fermenting In Kegs | BrüTech

- Fermenting beer in kegs brings many advantages. For starters - they’re stainless steel and easy to sanitize. They fit in your keezer for temp control. They’re pressure rated so you can ferment under pressure, easily purged of oxygen, and you can perform closed transfers. And you can ferment and serve in the same vessel.
But the humble corny keg wasn’t designed for any of this. It’s a serving vessel. You run the risk of blocked dip tubes, and questionable spunding practices.
So I’m attempting to assemble the ultimate fermentation keg. I’m using the prototype Clawhammer keg and customizing it with a pretty cool temperature control addition. Then I’m going to add some wort and see how it does. Will my franken-keg live up to expectations?

I love the homebrewer's mindset of experimenting and trying new things, but there comes a point where the cost of this keg + accessories you could buy a unitank with less clutter.
Are you overthinking the blockage issue, most kegs are rated around 130psi, that's quite a lot of pressure to force through whatever moist stuff you've got hanging around in your tubing/PRV.
When homebrew fermenters cost more than my commercial tanks... :)
This is rad btw
OMG. Just leave me with my plastic fermentation bucket!
I love this for so many reasons... it just goes to show the ingenuity of home brewers (and the folks that make gear for them) and because it's like a Rube Goldberg experiment for kegging.
Fermenting in a corny is (as Marshall would say) super rad. Sacrificing a few litres of beer is totally worth it for the convenience - cold crashing with zero suck back - yes please.
Oh! Take it from someone who knows: the tiny loop of steel that connects the ball to the filter on the dip tube is extremely easy to break off. Totally knackered.
i find you can use pliers and bend and close the steel loop once it breaks.
@@Jcbrovz Yep that would work. Unfortunately, in my case, the whole loop came away from the ball. It broke off at the point the loop is welded/soldered to the ball itself. 👍
It’s cool and looks awesome! I do have to wonder about the price, clawhammer makes great stuff but they make expensive stuff. I understand cost is relative and certainly spend whatever you can afford or want to. My guess is the entire set up shown will be in uni-tank territory in which case why not just get a uni-tank.
I am from the old school of home brewers and we were/are all about the diy (for example my electric rig is very “similar” to the clawhammer 240 but it costs a couple hundred bucks to make) I have to say I am not suggesting anyone not buy it if you want it I just personally like building stuff. I got if topic but I really need to see what the retail cost of that keg fermenter is before I make a judgement. It looks great but good looks often lead to diminished returns.
Great video Martin. Awesome job . Cheers 🍺
I'm excited to get my hands on one of the Clawhammer fermenters, love to see the customization and thought that went behind the product.
Maybe if you can get one free. Otherwise go get a 7.5 gallon sanke
Nice video. The kegs look nice. I saw Clawhammer's video on why they are doing further design changes.
Nice to see you on brulosophy! I think a shorter tee connection would help the coolstix reach cold crash temps. These fermenters looks awesome, thank you for the video!
I did some lookups and measuring, and 2 of these would fit quite nicely into a RAPT fermentation chamber as well, for those of you that like to ferment 10 gallon batches, don't like glycol, and are done with plastic fermenters or DIY'ing mini-fridges and with heating and cooling setups. Excessive but nice in the sense that it's turnkey and has a lot of valve fittings and internet connectivity options already there. I'm going to wait a bit and see how the iteration/improvement loops go with Clawhammer's offering, but I'm pretty excited about this as an alternative to the Spike CF10 if I want to split batches and try dueling yeast recipes.
RAPT Fermenter Internal Dimensions:
Width: 44cm or 17.32”
Depth: 50cm or 19.685”
Height: 130cm or 51.18”
Clawhammer Keg Fermenters
Width: 24.13cm or 9.5"
Height: 68.58cm or 27” tall (without accessories)
Great video, love the content!
I'm eagerly awaiting my preorder...
I am thinking about getting one or maybe two. I've looked at sabco and keg outlet. Trying to find what I want. And this the best thing yet.
usually in a glycol chiller the glycol temp should be between -4C (25F) and -8C (17) but is important what the manufacturer recommend.
I have a CoolStix as well that's now collecting dust. It's ok for fermentation temps but there's just not enough surface area to be able to cold crash. I got one as a gift and tested it in my Spike fermenter and when it came time to cold crash it took over 18 hours to go from 68° to 44° - then it just quit and wouldn't go any lower. In contrast, my glycol coil can go from 68° to 38° in about 3 hours. It would be cool if they could develop a mini coil that fits through a 1.5" TC, much the same way that a regular coil fits through a 4" opening.
Have done a lot of fermentation in kegs over the years and have had good experiences, I stopped when I wanted temp control and picked up a unitank. I think this is close to perfect though I wish someone would cook up a keg with a jacket for glycol then you would have a port for hop drop and spunding! Maybe as you are in the US you could try a cool zone wrap or similar.
Interesting seeing development of the corny keg format. I expect this setup to cost a bit more than the reasonably affordable second hand corny kegs. With that new price point, what's the benefit using the claw hammer setup vs. a unitank from any other brand?
Seems like the biggest drawback is still it's size.
A lid that fits the regular kegs but with a TC-connection would be cool. Might already be such a product out there?
For transparency, I've been fermenting in kegs for almost a year now and I love it. I use the Speidel Braumeister 10L so size isn't a concern.
The clawhammer will be $800 less than any comparable unitank on the market, including the accessories.
Yep - Aldi expresd has corny lids with TC on top
@@nattyj000 Do you have a web link to the corny lid with a TC?
I use a Sanke with Commercial keg adapter for fermentation and floating dip tube. I use heat but ferment in cool place. I use a kegland spunding valve also. 30L kegs work great for 23L brews and a 58L for 46L brews. Pressure closed transfer when done! I really like the safety improvements in the claw hammer prototype!
What floating dip tube did you get? I haven’t found one that will fit through the opening in a sanke.
@@nathanphillips5156 I purchased the kegland ones in the psi kit. 1 30l worked but the second I had to take a die grinder to the lip inside the keg to make it work.
I also noticed my coolstix didn't cold crash, they work for lagering pretty well though if placed in a temp controlled and moderate climate area.
Love brulosophy and always have an eye out for new content from Martin's. The production value on this one is spot on and what I've come to expect. I also have a huge amount of respect in Martin's opinion. That being said, i was never quite sure if this was supposed to be an informative video, product review, or a straight up advertisement. I would love to see the brulosophy approach to transparency and impartiality applied to videos like this with more vigour.
I completely agree, is this where the “show” is going? Should Clawhammer produced and posted this video on THEIR website? All the years I have read Brulosoohy, I don’t recall seeing articles with product how to or enhancement videos. Disappointed with this episode…one more thing - the cost for a setup like Martin is well over $1200 bucks……not sure of the exact price but this is not typical of any homebrewer I know of.
Thanks CraftyCAD. I should have been more clear of the terms. Clawhammer sent me a preproduction unit months ago before I even officially started at Brülosophy. No money changed hands and there was no expectation of a review. I got playing around and came up with this setup. There will be occasion gear reviews from time to time, where we’ll share our honest opinions.

@@TheBrulosophyShow Very much appreciate you taking the time to reply and for the clarification! I am always very keen to hear your thoughts & review on gear and processes. Looking forward to more great content from you and brulosophy team.
Brulosophy and THC (hehe) have been two of my most dependable sources of information since I started brewing. I’ve lost count of the times I’ve been down the wormhole of a particular brew or style and been able to find really good, useable info online through Brulosophy exbeeriments or watching Martin brew that particular style.
So thanks heaps to Martin and Brulosophy for all of your help and information over the years. I’m sure I’m not alone and I hope you guys realise just how much of a service you provide to the home brew community, even here in Australia!
When you first showed the cooling stick, I wondered if it would have enough surface area to efficiently cool the keg. A coil would be much more effective, but then again, that would take up extra space in the fermenter, where space is at a premium.
I've been fermenting in solely corny kegs for 2 years. I doubt it's gonna blow up 😂
This is very cool, but I’ll be sticking with my plastic buckets for now.
I really love the claw-hammer fermenter + all the add ons and this video was really fun to watch/ get my head around the possibilities. My only question, is using a standard corny actually a real danger? Until now I've never heard anyone talk about pressure releases becoming blocked.
This is the way.
you transferred to a second keg? isnt that defeating the point of the clawhammer?
LFG!!!!!
Could you use the dip tube to harvest yeast? Then the floating dip tube to transfer?
Interesting
Well, the ultimate fermentation keg would still allow you to do a hop drop, right ?
The rubber seal will let go long before a keg bomb
Why not just serve out of it?
is that a series 1?
Can you say an average price of this setup, compared to a regular conical pressurized fermenter???
Interesting design, but what's the cost? It's an interesting alternative to the unitank
Over $600 with his final setup. That doesn’t include the accessories that he didn’t use.
fermzilla
Make one of 12 Gallons!!
Cool video as far as gadgetry goes, but this is a LOT of money to gain 4-6 extra pints of beer honestly…
This setup is 1,000$
1,000$ for a fermenter.
1,000$
Sure is nice to be a 'content creator' on YT to get this free.
Go do it then ?
@@tomasbeha1645 And that went right over your head.
You missed the point that it costs 1,000$ for that setup. It's not like I said it not once, not twice, but three times.
Why would you want to tie up your 1,000$ fermenter setup just cuz you can serve out of it?
Would you?
@@miked.9364 If I had the finance, absolutely
@@tomasbeha1645 Why?
And all to gain a half gallon of packaged beer, which is 4 pints. Like cmon just split the batch into two cornies if you really need the 4 pints lol
geez. way too much bling. nothing wrong with a corny, kind of pointless knocking something that costs $50-80 AUD with a $12 floating dip tube and $6 gas post swap on the liquid post. $30 spunding valve and $4 10psi PRV.
130 psi rated vessel.. That Clawhammer would fit in a chest freezer... wouldnt fit in a kegerator, only an upfright freezer or fridge. pass..
cheep and cheerful doesnt need another $800 thrown at it.
