3" Copper pot still on a keg boiler. My first still!

Post by garage_distiller »

Hi everyone-

After reading here for months, buying 4 different distilling books, and spending God only knows how many late nights dreaming, I built my own fully functional pot still.

Here are the specifics:

7.75 Gallon beer keg boiler
Turkey cooker for heat
20 Inch length of 3 inch copper for the still head
10 Feet of 1/2" copper wound into a coil and fitted into a 5 gallon bucket as a condenser
All solder joints were made with lead free solder. The 3" tri clamp ring was joined to the still head with silver solder.
Gaskets in the 2" to 3" adapter are teflon

I now have several very successful runs under my belt and I have learned a little bit. Most importantly:

1. READ, READ, READ. Every question I have ever come up with has been answered in these forums multiple times. How did we ever survive without the internet?
2. Take your time, slow and steady beats rushing every time. This goes for still construction, mashing, distilling etc......
3. Start simple! My first idea for a still was a four plate column with a dephlegmator, I quickly realized I didn't even understand what went on in a still. So I got down to basics. I couldn't be happier with what I ended up with.
4. Hydrometers are very fragile and will break at the worst of times. Treat them with care and always have a spare on hand!

With that having been said, on to the copper porn!

My still in its first iteration. I have since changed the output drastically. Although I have to say it worked VERY well this way. But it just looked awkward and was difficult to set up. This picture was taken on the very first vinegar/water cleaning run hence the cloudy distillate in the jar.

Image

The way she currently sits. Note that she is polished as well! I know the worm bucket is pretty unsightly but dang does this thing work like a champ.

Image

Hard at work distilling some of Rads All Bran mash. What a great recipe that is! For you sticklers out there, yes the worm output is through a coffee filter, it probably isn't needed, but I really don't care, I'm doing it regardless. And yes, the filter is sitting in a plastic funnel. But the funnel is PETE #1 so I feel safe with it.

Image

Another angle showing off that pretty copper!

Image

Close up of the worm bucket. For the few dollars I have invested it sure does work well.

Image

A big jar of distillate from Rads All Bran recipe. Good stuff!

Image

My still routinely pulls 140 proof on stripping runs which I think is pretty good for a pot still. I would guess if I packed the column with scrubbers I could see a significant increase in purity on the stripping runs. I don't mind running my product through a second time however, sometimes even a third! This thing rocks. I am very happy with it! Thanks to everyone who make this such a great forum, without all the contributors here I never would have made it this far.

Welcome to HD garage_distiller...

Nice rig you have there... :thumbup:

I'd put 2 x 2qt frozen milk canisters into the flake-stand to keep the water cool...

Have fun and stay safe man... :thumbup:

Just noticed... Cant really tell from that angle...
Is that orange container/funnel plastic your collecting into... :thumbdown:

Only glass, copper or stainless...

If I'm wrong, then please disregard... See you around... :thumbup:

Haha! Good eye there Samohon!

They funnel is indeed plastic. But it is marked PETE with a 1 in the triangle.

Most plastic booze bottles are marked the same. Do you think I should ditch it? I figured it was safe.

Thanks for the compliments!

If its marked PTFE GD, then its proven to be safe if PETE then ditch it... Make a nice copper one...
I did a tutorial for a funnel a while back... Click Here...

Nice shiny copper, wont be long in acquiring a nice patina the more you use it... :ewink:

Be safe man... :thumbup:

Very nice build. You really don't need the filter or funnel anyways, just run it right into your glass jars and everything should be just fine.
Edit, I swear you are in My garage!! Looks just like my door, floor and snow.

If you are using the funnel because the stream is unsteady, you might have flat spots in the worm, although it dosn't look like it.

If you have done a vinegar cleaning run, and more than 2 alcohol runs, you should be sweet and not have to filter it. If you need to, do it afterwards.
Either way, its not a plastic freindly zone here.

A cloudy wash will give carry over and a milky product in a simple pot. Make sure your wash is clear. Rack it twice if you need to. Then every bottle should come out looking like distilled water, but better.

I reckon you could smooth out the transition from the downcoming tube into the worm, take away the 90 degree bends, use a large radius bend. Wise move on the cold water add for the bucket (mayby run a hose under the garage door for the output??)

Other than that, looks like a nice still, and a nice logical place to get some learning done. Won't be long and you'll know all about dephlagmaters and columns and weather or not you want to run/own one (I think you will 8) )
You design it, I make it. Copper and Stainless. Down under. PM me.

Thanks for the kind words and the advice everyone.

I really thought the PETE funnel was a good choice but I will ditch it!

The stream coming out of the worm is very steady. Once the worm bucket starts to steam I just crack the valve on the water hose and let a slow trickle of water run through the bucket and it keeps a nice steady stream of cool distillate run out into the collection jar. It is easy to tell when more flow is needed because the stream becomes unsteady so I just adjust it accordingly.

Really like the build! Hope you dont mind but i will be modeling my still after yours. Good clear pics seems simple enough with a good product result. Will be starting to gather materials soon. Any tips you wish you had while you were building?

Where did you find you 2" to 3" adapter?

I think I'm going to grab a bigger keg though. the 15.5 kegs are for sale on ebay for about $45.

Nicely done Garage:

One comment on shining up the copper, it looks beautiful but it screams "THIS IS A STILL".

I distill out doors and we have houses up on a hill a a ways away. I was going to get out the power buffer and elbow grease, but decided that being subtle was a better choice.

Not taking anything away from yours, it look awesome, but it's something to consider if the public will get a glimpse of the equipment.

Where did you get that 2" to 3" adapter? Ive been looking for that exactly for my keg but the cheapest i have found is copper for $54.

I have no objections at all to you using my still as a model. In fact I take it as quite a compliment! The finished product is indeed excellent and I currently am playing with a corn based recipe that is in its third iteration and I have found that sitting the distillate from it on some cinnamon sticks for a few weeks makes for a product that is eye poppingly good! The best tip that I didn't have was to make sure you have enough torch. I used MAPP gas to solder my 3" copper and it was BARELY enough to do the job right. If someone was doing a 4" build then an acetylene torch would be a must in my opinion. By the way I got my 2" to 3" adapter from http://www.hillbillystills.com They rock!

Thanks Bull Rider!

I shined the copper up because, well, I WANTED it to look like a still! Where I live there is no danger of people seeing what I am doing unless I want them to see what I am doing. The only glimpse the public will get of what I am doing is right here on this forum. Thanks for saying it looks awesome though, that is quite flattering.

I got my adapter from http://www.hillbillystills.com These folks are nothing short of awesome. They have everything you need and the shipping is FAST!


I am doing a slight redesign on the still right now and new pics are coming shortly. Thanks again to everyone who has expressed interest. This is a great hobby!

real nice build,,, clean solder joints,, everythings nice n straight.... wish my first stll turned out that nice.. did you by chance pickle the brass unions? it looks like one end is copper while the other end is brass with brass nuts... i know some guys dont worry about such a small amount of brass and others are totally against it as brass can contain lead,, i used a brass ball valve on my vm head but i did pickle it,,, better safe then sorry imo.... but great job.... i bet it stripps down that small boiler really really fast...
death is inevitable ,,, but its also only the beginning..

Nice job there. One area of caution since your adjustment to design. Your distillate collection point appears to be a little close for comfort to your open flame source. If you collect in open containers...that vent vapor out the top...that could easily catch fire when the vapor rises up into the path of the flame. Just be careful.

I am in the process of making a valved reflux still.

I have gotten most of my copper at http://www.plumbingsupply.com/copper.html" onclick="window.open(this.href);return false;" rel="nofollow

I have found that it is expensive (no matter where you go) but if I tried to buy my 3 feet of 2" copper locally, I would pay much more (because they only sell pipe that size in full length of 10 feet)

I have bought smaller copper I needed Locally (Lowes/Home Depot, etc).

I am working on my "Boiler" at this point. Not sure what I want to use. I saw that someone mentioned you could buy a keg off of eBay for $45, but I can buy a keg of beer locally and enjoy the beer and then just let them keep the $30.00 deposit. No shipping, Enjoy the Beer (or distill it) and get a Keg/boiler for $30.00.

(Note for Mods and Admins: I intended to post this on this thread earlier, but apparently I made a new thread. Sorry about that.)

For a potstill, I think you did a great job. You may want to consider a liebig condenser over that worm configuration. It will do 2 things, 1st it'll get that collection point farther away from your heat source and 2nd, it will get rid of the homer bucket and the pain if dealing with changing the water in the bucket. The other thing I like about it is that you can remove that head an put it on a 15.5 gal keg and kick some azz.

Looks really good! How do you fill and clean the keg though the small hole? I'm going to use a keg that I have and was just trying to avoid cutting a large hole in it. Thanks.

To fill, Use a large funnel to fill the keg. To empty, Siphon it off with hose until it's light enough to lift up. Then dump it and rinse with hose. Pick it up sideways...rock your body back and forth to roll the water inside it. Then swoosh it out. Leave it upside down to drain.

Garage_distiller i just wanted to let you know that this still has been an inspiration to me, love the build very simple and i copied a lot of it as my own, the only changes i made were i went from 3" and skimped out to 2", and i put my copper unions at the downspout instead of before the elbow, this way i can go from a 5gal to 15gal easily with the change of only the downspout. again great job

Nice build i see that you ditched the 45 and went with the union on the horizontal to the downward 90 :thumbup: . I made the mistake of using a 45 now i have to go back and do some modifications like you did. Simple and well done!
