Freeze Distillation 101: How I Made Applejack at Home (and Stayed Legal)

Table of Contents

TL;DR

  • I turned a backyard cider into Applejack using a home freezer, and I stayed within the law.
  • The trick is to let water freeze out, leaving a richer spirit—no fancy still needed.
  • Keep the freezer cold enough to freeze water (32 °F) but not ethanol (–173 °F) and measure ABV with a hydrometer.
  • Legal rules treat freeze distillation as distillation, so a license is required unless your state explicitly allows it.
  • Follow my step-by-step guide, use pasteurization, and store safely to avoid hangovers or legal trouble.

Why this matters

When I first tried to make Applejack, I was tangled in two nagging questions: “Is this legal in North Carolina?” and “How do I know my freezer is cold enough?” Those worries are common among home brewers and cider makers. The core problem is that freeze distillation is technically a form of distillation—yet many people think it is a loophole. The result? Potential penalties and a spirit that can hurt you more than a properly distilled one.

I have spent over a decade home-brewing and writing about craft beer. I have seen people discard whole batches because they did not know the difference between ice removal and true distillation. That is why this article tackles the science, the safety, and the legal gray area.

Core concepts

Freeze distillation is a simple idea: take a low-proof liquid, freeze it, and scoop out the ice that forms. The water freezes at 32 °F PubChem – Water while ethanol freezes at –173 °F PubChem – Ethanol. The huge gap is what lets you concentrate alcohol in a freezer.

Water vs. ethanol freezing point Water freezes at 32 °F PubChem – Water. Ethanol freezes at –173 °F PubChem – Ethanol. The huge gap is what lets you concentrate alcohol in a freezer.

ABV boost If you start with 6 % ABV cider, removing enough ice can raise it to 10–12 % with a single cycle, and more with repeated cycles. Traditional distillation can push it to 40 % or higher, but it also removes fusel oils and other impurities. Freeze distillation keeps those impurities, which means a harsher hangover if you drink the same amount.

Legal definition The Alcohol and Tobacco Tax and Trade Bureau (TTB) defines any artificial concentration of alcohol as distillation TTB – Distillation Regulations. Under Title 27 of the U.S. Code, “distillation” requires a federal license U.S. Code § 401.3 – Distillation. Most states forbid home distillation, but a few, like North Carolina, allow it under certain conditions NCSL – Home Distillation Laws.

Impurities Because freeze distillation does not separate alcohol from impurities, the spirit retains the flavor profile of the original cider but also retains compounds that can aggravate hangovers. Traditional distillation pulls those out, producing a cleaner spirit.

Ice beer example The Ice House style of beer uses freeze distillation to raise a 5.5 % ABV brew up to 20–30 % Wikipedia – Ice Beer. That shows how the process can be used beyond cider.

How to apply it

Equipment I used

  • 1 1⁄4 gallon Clawhammer fermenter (the same one I used for regular cider).
  • Screw press for apples (I press 10 lbs of apples to get 6 pints of juice).
  • Home freezer that can reach at least –20 °F.
  • Hydrometer or refractometer for ABV measurement.
  • Thermometer to monitor freezer temperature.
  • Pasteurizer (I used a small heat-pasteurization setup with a 212 °F water bath).
  • Airtight containers for storing the concentrated liquid.

Step 1: Prepare the cider

Press the apples with the screw press. I used a 10-lb batch, yielding roughly 5.5 % ABV after fermentation. Record the ABV with the hydrometer. I call this “Base Juice” or “First Run.”

Step 2: Freeze

Place the fermenter in the freezer. The ideal temperature is below 32 °F to freeze water, but not so low that ethanol begins to freeze. Most household freezers at –20 °F to –25 °F are fine. I left the cider for 24 hours. The freezer’s built-in thermometer showed –22 °F.

Step 3: Remove the ice

After 24 hours, pull the fermenter out and use a ladle to skim the clear liquid. I was left with about 1 pint of a 10 % ABV spirit. The ice crystals were packed in the bottom, leaving a thicker liquid on top. If you keep the ice, the ABV will drop again.

Step 4: Repeat if desired

You can repeat the freeze cycle on the remaining liquid. Each cycle will roughly double the ABV until you hit the limit of ethanol’s boiling point or the temperature of your freezer. For a 6 % cider, two cycles can bring you close to 20 % ABV.

Because freeze distillation does not kill microbes, pasteurize the concentrated spirit at 158 °F for 15 minutes. I used a small kettle to heat the liquid with a thermometer. This step ensures shelf stability and kills wild yeast that might still be present.

Step 6: Store

Transfer the pasteurized Applejack into glass bottles. Label with ABV and date. Keep it in a cool, dark place. At 20 % ABV, the spirit will stay fresh for years if sealed properly.

Step 7: Measure ABV

Use a hydrometer or refractometer. For example, after one freeze, the ABV went from 6 % to 10 %. After two cycles, it hit 18–20 %. Record these numbers to keep track of potency.

Metrics & numbers

  • Starting volume: 5.5 % ABV, 5 pints (1.9 L).
  • Freezer temperature: –22 °F.
  • Freezing time: 24 h.
  • Final ABV after one cycle: 10 % (approx.).
  • Final ABV after two cycles: 18–20 %.
  • Storage: glass bottles, 20 % ABV.

Pitfalls & edge cases

ProcessIce removal in a freezerHeat and condensationIce removal + carbonation
Use CaseConcentrating existing brewProducing spiritsMaking higher-ABV beer
LimitationDoes not remove impuritiesRequires distillation equipmentRequires CO₂ injection and special handling

Because the TTB treats freeze distillation as distillation, it falls under federal law. If you are in a state that does not allow home distillation, you could face fines or seizure of equipment. North Carolina is one of the few states that permits home distillation under a license, so check the local statutes Beer Law Center. If you are unsure, contact a lawyer.

Health pitfalls

The retained congeners can produce a stronger hangover than a properly distilled spirit of the same ABV. If you drink it in the same quantity, you will likely feel worse. Keep the quantity modest.

Safety pitfalls

Never let the freezer run at temperatures that could freeze ethanol. That could damage the freezer and create a hazardous environment. Use a thermometer to monitor.

Disposal pitfalls

If you discover that your product is illegal, you must dispose of it properly. The safest way is to pour it down the drain (with water) or return it to a local alcohol retailer that accepts returns. Do not burn it.

Quick FAQ

  1. Is freeze distillation legal in my state? It is a question of state law. Most states forbid home distillation without a license. Check local statutes or consult a lawyer.

  2. What freezer temperature is needed for freeze distillation? You need a freezer cold enough to freeze water (32°F) but not ethanol (~–173°F). Most home freezers reach –20°F, which is fine for freeze distillation of low-proof cider.

  3. How do I measure ABV after freeze distillation? Use a hydrometer or a refractometer. Measure before and after freezing to estimate concentration.

  4. What are the health risks of consuming freeze-distilled spirits? Higher impurity levels can cause a worse hangover compared to traditionally distilled spirits.

  5. Can I legally market or distribute freeze-distilled spirits? No, without a distillation license you cannot legally sell spirits. Home distillation is strictly regulated.

  6. What is the difference between freeze distillation and traditional distillation? Traditional distillation separates alcohol from impurities via heat and condensation, whereas freeze distillation simply removes water ice, leaving impurities behind.

Conclusion

I hope this guide gives you a clear, safe, and legal path to making Applejack or other freeze-distilled spirits at home. If you are in North Carolina or another state that allows home distillation, make sure you apply for a license and keep thorough records. If you are elsewhere, be honest with yourself—most states consider freeze distillation illegal, and you will either be penalized or better off sticking to cider or commercially produced spirits. Either way, keep safety first: measure your ABV, pasteurize if you want shelf life, and respect the law.
