How to Distill - 101

Although our stainless steel distillers and copper still parts kits can be used for many things (water, essential oils, fuel alcohol, spirits, etc.) we've had a ton of requests for a simple tutorial on how to distill alcohol. Before we answer that question, we need to tell you this: Distilling alcohol is illegal without a federal fuel alcohol or distilled spirit plant permit as well as relevant state permits. Our distillation equipment is designed for legal uses only and the information in this article is for educational purposes only. Please read our complete legal summary for more information on the legalities of distillation.

Next, we recommend beginners (and even experienced distillers) buy a good book on the topic of distilling because we'll never be able to explain everything there is to know about distilling in a blog article. Also, we don not claim to be experts and this information is for entertainment and educational purposes only. It is not intended to be relied upon by anyone for any act or decision whatsoever.

Anyone who follows the process outlined below should either a) reside in a place where brewing and distilling is legal, b) have a fuel alcohol permit and use the final product for fuel, or c) have a commercial distillers permit.

That said, here's a simple outline of the distillation process:

  • Make a mash
    • This can be accomplished by either using cereal grains such as corn, barley, and rye, or it can be made using granulated sugar.
  • Ferment the mash
    • After a mash is made, cool it to 70F and pitch yeast. Cover with a lid and add an airlock. Leave it sit for 7-10 days at room temperature. During this time, yeast will convert almost all of the sugar into alcohol. What will be left is called a "wash."
  • Distill the wash
    • Siphon the fermented wash into a still and heat to approximately 175 degrees Fahrenheit. Methanol starts to boil in the high 140's and ethanol will start to boil at about 174F. Anything produced by the still while liquid temp is under 174 can be assumed to be methanol (which is poisonous) and should not be consumed.
    • As ethanol starts to boil out of solution and the concentration of ethanol in the wash contained within the still starts to decrease, still temperature will need to be increased for the still to continue to produce. What this means is that boiler temp will be roughly 175F at the start of the distillation process but will need to slowly rise to approximately 210 by the end of the process.

Under no circumstances should an individual ever distill or sell alcohol without a permit. If an individual chooses to distill alcohol, make sure to obtain all applicable fuel or spirit permits (explained in the distillation law summary, mentioned above).

  • My question is about rerunning tails and adding flavor in the thumper, I get so many different answers its confusing.I’m just starting out and pretty much what I’ve made so far isn’t that tasty so NY queastionis can I put all I’ve made so far together with water and redistil it for a better strength and taste? And if I’m adding stuuf to thumper gor taste with what (later or alcohol) do input with it and how much? Hope you can help, thanks John

  • You guys need to chill, you use malted barley to turn the starches into formentable sugar if you don’t have barley you have to use amylase. You guys ask the stupidest questions.if your fire keeps going out yes you have to throw away the first out of the still. You start getting alcohol at 175 degrees the fist will start vomming out at 134 degrees thats acetone.

  • I was reading your article about how to make a corn mash. I’m new to this and if i read it correctly it seems that you strain your mash prior to pouring it back and forth between two buckets and adding your yeast and putting it in your fermentation bucket. Is that correct? The reason I ask is I thought that you cooled your mash, added the yeast, dumped it back and forth and then put all of it in the fermentation bucket waiting to strain it until just before you put it in the boiler. I think I confused myself. thanks!

  • We’ve run our first batch but I confused about distilling it twice. Can you please explain in more detail.
    Do I take what we have made and cut it with water by 30% and rerun?
    Thanks for your help!

  • I am new to distilling and want to try my hand at it. What books do you recommend for beginners? Any help would be appreciated

  • I noticed that my heat source has a safety system to shut it self down and start up again causing the flow to also stop and start. Can this ruin my whole batch? Tastes Awesome but is slightly cloudy.

  • In your corn whiskey recipe there is only the sugar that released from the corn Can I also add sugar? I am saving to get either the 5 or 10 gal still. I watch a lot of videos and this is the only one that doesn’t use sugar but one of the few that uses the malted barley which releases the corn sugar I’ve heard. so I’m just a bit confused. Can one use both? Thanks!

  • Newbie. We made a run and it was the smoothest best tasting shine I have ever had. We cut the heads and tails and had a 90 proof first run. After 2 weeks in the jar it tasted like rubbing alcohol. Why did the taste change?

  • do I have this correct on the mash.
    1: heat 5 gal H20 to 165 deg F add 8 1/2 lbs flake maze ( corn) stir 3-5 min
    2: heat mixture to 152 deg add malted barley stir for 1-2 min. let sit for about 1 1/2 hours.
    3: heat 1/2 cup H2O to about 110 deg add 1 table spoon sugar. mix mixture
    4: when corn & barlet mixture temp at 70 deg add yeast mixture and stir.
    5: when mash no longer bubbles ( 5 to 7 days) and has a foam on top its ready to still?
    can I let the mash sit in the original container if i plan to pump mixture into pot for stilling? can what is left in the bottom of the mash mixture be reused for another mash mixture?
