I own 2 Grainfather GF30s and they have built in cooling jackets, so much easier than a cooling coil to clean. Your list is wrong!!!

Im going to build something similar. That screen is a good idea. I think you also have to isolate the beerline against condensation. You dont want mold in the wall.

I have been using the original BRUAMEISTER 50L. Absolutely the BEST! HANDS DOWN! this was the first one if not one of the first to market with single vessel. Absolute high quality. Easiest to run as it pumps from the bottom. NO FITTINGS TO CHANGE POSITION AS YOU BREW. Never have to disconnect here and connect there.... Dough in , Mash, Lift lauder and drain (and sparge if you wish), boil, chill...done. NEVER DISCONNECT, move to another port and re-connect etc. ALL super high-quality SS. What you expect from German engineering. Worth the price All day long!!!

You are not comparing like with like! The variety of malts would surely affect the potential efficiency. You should be doing each recipe both the "proper" way and the "cold way" and comparing. I have consequently stopped watching the video half way through :) I had been hoping for a revelation! Actually I'd already seen the Brulosophy episode on this topic.

So with the clawhammer system, without sparging you can expect to get 60% efficiency?

HI Matt! I just purchased my system and I have been missing my expected OG by 12-13 points on each brew. I use Brewfather to create recipes and use the default equipment profile for the 120V Clawhammer system. Its expecting an efficiency of about 70%, does that seem to high and possibly the reason for missing my OG by the same measured amount? Im really stumped on this. Otherwise love the system!

Love the funky 80,s retro background tunes lol 🎉😅

On a Wemos D1 I flashed Tasmota 14.2.0 Sensor release. I had to change to D6(GPIO12) = DAT and D5(GPIO14) = SCK. Now HX711 weight is displayed. But I am still struggeling with the wireing of the sensors

13:30 you mean celsius or fahre these fermentation degrees?

wanted to see how the new inline worked , how much it made ? did you post another video with full working explanation ?

Great run down and review. And OBTW, I love, love, LOVED you in Harry Potter!

I just purchased the same sink/faucet and am curious why you initially clean off the Clawhammer outside as opposed the sink. Because of all the hop debris? Are there some things you’re not comfortable pouring down the drain? Thanks!

How much watts of do you think this cooler cool? Lets day a PC drawing around 800 watts from the wall.

I got my most efficient lauter and sparge by accident. My mash tun is a cooler with a steel braid strainer. I cleaned out my mash tun, dumped in the strike water, stirred in the grains, then realized I left the strainer out. Rather than messing up my temperature at that point, I let the mash sit for two hours. Then I scooped the grain out of the cooler into buckets, cleaned out the spigot so it wouldn't clog, put the strainer back in, put the mash back into the cooler, and rinsed the scoop and the buckets with sparge water. I ended up with a higher gravity than I was shooting for. That extended mash coupled with the extra handling must have squeezed more of the goodies out of the grain.

Trying to decide on the 10 gallon or 20 gallon I want to do high gravity beers and wines. Do you think the 10 has done everything you wanted to do.

Very helpful video, thanks for that. I saw that the bottling/canning pressure is 6 psi, but what is the pressure, temperature and for how long do you carbonate the beer? Thank you!

Excellent video, thank you! Will be trying this later in the week. Cheers!

This is amazing!! I would love to attempt this. Thank you so much! Liked and subscribed 😊

I would think that for salts if you put 7 gal worth in up front and then mashed with 6 and sparged with 1 would be the same as if you spread out the salts over mash and sparge

If we need cooler temperature, do you think we can use alcohol instead of glycol ?

Wow Man! thanks so much for putting this together. I actually have a spreadsheet on SS conical fermenters that I just spent several hours making today - then I found this! so much bet ter than mine. 🤣 THANK YOU

How do you avoid over filing the keg (which I'm assuming will just spill out the gas disconnect)? Could you use a check valve gas disconnect which I'm thinking will just stop the flow when liquid hits it? My brew batches are normally a couple of litres more than the 19 litre corny and i transfer into a purged but open corny so I see when it's full and i just bottle the extra.

What about the vevor?

I didn't understand why you needed the reducer? Could you elaborate? And does the reducer reduce the overal effect?

Great video! When you note that you aren't going to use glycol or a fan for your lines because they are less than 6 feet, are you referring to the length of the lines outside of the keezer? Or the total length of the lines? I'm looking to move my beer taps to the top of my bar and I am going to need to run my lines outside of my kegerator. The length from kegerator to tower is probably about 3 feet and the last thing I want is foamy beer! Thanks!

I saw u like harry potter ❤

2 Questions...if you have multiple fermenters, you would just have multiple pumps in the ice chest correct? Also, are you going to make any more videos? Enjoy them very much.

Everyone should really understand the Beer coming from the Keg to the Taps MUST be relatively COLD and it's a shame, but I would have liked to see him pour beer. Because it would be a ton of foam beer. He doesn't have a true method or proper insulation to keep the Beer at a cold temp to avoid foaming. Let me know if anyone has built something like he has shown and it worked. I'd be VERY surprised to see no foam. Especially if the beer sits in the line for more than 10 minutes then pour from the Tap. ANYONE'S Thoughts???

You should have a lot more subscribers!! Watched like 5 of your videos in a row.

Something to be cognizant of is that you're pulling a vacuum on the inside of your house. Air will need to come back in from the outside to replenish what you're exhausting. Those big fans move a lot of air. This can be dangerous if you're also running a natural gas furnace or water heater as the exhaust can be caused to back up into your house and lead to carbon monoxide issues.

Your a hero and should be recognized for the beer nobel prize. I was about to literally do this same experiment with 4 batches of the same exact grain bill and see the efficiency results. Saved me a lot of work and now my wife wont divorce me. Subbed

You seem to have missed Klarstein.

I've in the process of trying to do this myself, but I'm having some calibration issues. I've been nosing around with a multimeter to see if I can find anything strange, but haven't yet. Do you have any advise on how to troubleshoot the wiring, or are there any resources online that could be useful?

great interview.

No one noticed the SNES mario music but me?!?!??! Love it 🎶

Wow dude thank you for putting in this work. You da mon. ya mon.

Thanks for this video and Excel sheet. However, should the low-budget fermenter Best Value be the Anvil Crucible instead of the Anvil Foundry, as this is an AIO system?

Great video!

You can pull up and twist the ring on your lid's pressure release valve 90 degrees to lock it into an open position.

Matt, really well done video and I’m about to embark on the same journey of three taps through the wall. A year later, do you have anything you wish you would have done differently or is the system doing well?

What does dedicated site mean? Could you add a definition at the bottom to explain what each column means and why you decided to include it. Thx

How did you get the circ pump stay attached to the bottom of the cooler?

I was wondering if your inline fan is still working? I did something similar and the fan quit on the first brew. Maybe moisture or just junk. Thank you!

elementary brewing co. sent me your way. thought id check it out. looks good. i struggle sometimes as well making beer clear. perhaps if i skim the protein and use whirlfloc i think id be golden. i bought some finings so ill use it on my next beer. light lager is my next to brew but not sure when ill get around to it. have a few recipes that im going to flip a coin and see which one will be next

Hi Matt. Thanks for the video, I'm likely to create a fermentation chamber similar to yours, given I'm in a colder climate (Tasmania, Australia). Now that you've had this chamber for a few years, have you found that it works perfectly every time, or is there anything that you'd do differently? i.e. extra heating elements? Does it stay cool enough on it's own during Summer to not require a cooling system? Thanks in advance.
