Double distilling moonshine is a process that involves distilling your mash twice to create a smoother, more refined spirit. This method is popular among moonshiners because it significantly reduces the alcohol's impurities, resulting in a cleaner, better-tasting product. Here's a comprehensive guide on how to double distill moonshine, optimized for search engines to help you find the information you need.
Understanding the Double Distillation Process
Double distillation involves running your mash through the still twice. The first run, or "stripping run," removes most of the water and alcohol, leaving behind a low-proof distillate. The second run, or "spirits run," collects the pure alcohol and discards the remaining water and impurities. This two-step process ensures that your moonshine is smooth and free of unwanted flavors.
Gather Your Equipment
Before you begin, make sure you have the following equipment:

- Stainless steel or copper still
- Thermometer
- Collection vessels
- Mash (fermented grain or fruit mixture)
- Cooling system (ice bath or water pump)
Preparing Your Mash
Ensure your mash is fully fermented before distilling. The fermentation process converts sugars into alcohol, which is what you'll be distilling. Once fermentation is complete, you're ready to begin the double distillation process.
First Distillation: The Stripping Run
The stripping run's primary goal is to remove as much alcohol and water as possible while leaving behind the impurities. Here's how to perform the first distillation:
- Heat your mash slowly, monitoring the temperature with your thermometer.
- Collect the distillate as it comes off the still. Discard the first 5% (foreshots) as it contains methanol and other harmful compounds.
- Collect the middle run, which is the part you'll use for the second distillation. This should be around 30-40% of your total distillate.
- Discard the tails, which are the remaining compounds that come off the still. These are mostly water and other impurities.
Second Distillation: The Spirits Run
The spirits run is where you'll collect your final product. Here's how to perform the second distillation:

- Collect the middle run from your first distillation and place it back into the still.
- Heat the liquid slowly, monitoring the temperature.
- Collect the distillate, discarding the first 5% (foreshots) again.
- Collect the middle run, which is your final product. This should be around 70-80% alcohol by volume (ABV).
- Discard the tails, as these contain mostly water and impurities.
Adjusting Proof and Aging
After double distilling, you can adjust the proof of your moonshine by adding water or redistilling it. You can also age your moonshine in oak barrels or other containers to add flavor and smoothness. Keep in mind that aging will reduce the alcohol content slightly.
Safety and Legal Considerations
Always remember to follow safety guidelines when distilling, such as keeping an eye on your still and never leaving it unattended. Also, be aware of the legal requirements in your area for distilling alcohol. In some places, it may be illegal without a license.
Double distilling moonshine is a rewarding process that requires patience and attention to detail. By following this guide, you'll be well on your way to creating smooth, delicious moonshine that you can enjoy or share with friends. Happy distilling!
