using Kegs for Mashtun and fermenters.

Post by Stircrazy » Thu Apr 08, 2021 6:56 am

I have done a few searches and cant seam to find anything.
is there any DIY info for converting beer kegs into mashtuns and fermenter set ups? or is it better to go to a Beer spicific forum to get that info?

Thanks
Steve

The word for this is Keggle

Here is a example of some previous discussion

There are a few members here that mash and ferment on grain in a keggle. Twisted Brick for one, does 12.5 gallon ferments in a keggle.
Use all your senses, and its not that hard. You just have to pay attention.

There's a crapload of videos on YouTube. All one needs is a $2 cutoff wheel on a hand-grinder and a way to maintain a constant radius for your cut. Tip: get a stainless steel lid (not plexi or plastic - they scratch and harbor bacteria) before you cut your hole. If you put a drain (ferrule) on the side bottom, you could lauter single malt mashes to ferment off-grain.

I can't tell you how versatile this config is and how many hours it has saved. The keg ($35) and barrel dolly ($25) came from Craigslist. The lid ($5) from the scrapyard.

nice. I am trying to source a few kegs right now.
two months ago they were all over now they seam to be hard to find.

Sence 90% of my plan is to do 100% grain, I want to set up a grain mashing/sparging rack and plumb everything in
so I just open valves to direct liquid to where I want it to go. I might go with the cooler for the actual mash tun,
but I think everything else will be from kegs.

Consider flipping the keg, and using the sanke tap as a 2" drain on the bottom. Cut off the "top" that was the bottom.

You lose your handles this way, but mount some legs and wheels on it and its good to go!

The only downside is that you now can't use heat on it. Lots of blankets as insulation work fine when you dump boiling water in to gelatinize the corn.

Can you run HOT water through a 'mash cooler worm thingy' as a heat source?
With a bit of innovative plumbing and a suitable pump you could run it from (and back to) a hot water system...

Or better, steam the mash

No, unfortunately. There simply isn’t enough heat in hot water to to be efficient. The piped water first needs to be heated under pressure to above boiling and it’s easier to just make a steam wand like a thumper.

In theory if you have very well insulated piping you could maintain the heat, but I don't think you could effectively heat. As stated above, a steam wand is a better option for this. (which I've considered, but not needed to do.)

I was thinking of a 'mash cooler' with hot water, more as an aid to warming the mash before actual distillation...

why cant you use heat? sems to me it would be just as easy to put an electric element in, or are you talking for the sparge or fermenter? I am thinking the kettle. I wont be using gas heat or corn :wink: but reading the other posts has got me thinking, I will never need to boil water, unless I use corn, and then I can use the kettle, so it is feasable for me to build in coils and run warm/hot but sub boiling water through it to maintain temps. would just take a PDI temp control and a circ pump. so many things possible, its jsut time and money. on the bright side I have three Kegs coming
