How to Make Moonshine: What You Need to Know First

Let's be honest: the definition of moonshine is a mess. You might think of the Prohibition-era booze that could make you blind, or maybe you picture people making it in their bathtubs. The label is so confusing that even Nelly crafted his own celebrity “moonshine”, which was really just a fruity, lower-proof spirit. So if you're looking up how to make moonshine, you need to know what you're actually getting into. Let's break down how is moonshine made and what this legendary hard liquor truly is.

Many people think of moonshine as some sort of off-limits alcohol, but it’s also a term for a class of unaged whiskey.

So, what exactly makes moonshine, moonshine? What is moonshine made out of? And can moonshine make you blind? Let’s dive in and explore the difference between the two definitions of moonshine and learn about the dangers of moonshine production and consumption.

So, What Exactly Is Moonshine?

The first moonshine came around in England in the late 1700s, but the word moonshine has been around since the 15th century. Fundamentally, moonshine was created to avoid paying taxes on high-proof liquor production.

Originally, the term “moonshine” referred to a distilled liquor produced and/or distributed illegally. The term “moonshine” comes from the tradition of making the liquor under the cover of darkness to avoid detection. Over the years, it developed a standard definition as a clear, unaged, high-proof whiskey made from corn. This definition was commonly used during Prohibition in the U.S. in the 1920s. Other names for moonshine include rotgut, white lightning, white dog, and corn liquor.

A Quick History of American Moonshine

Moonshine has a particularly rich history in the United States.

• The Whiskey Rebellion. Moonshine first became popular in Pennsylvania in 1791 after the new federal government enacted a hefty tax on liquor to repay debts from the Revolutionary War. This sparked three years of (sometimes violent) protests known as the Whiskey Rebellion, during which Pennsylvania farmers and distillers attacked and intimidated tax inspectors to prevent them from collecting the tax. Moonshine production was a popular nonviolent way to protest the tax.
• The Whiskey RIng. History repeated itself in St. Louis in the 1870s when another tax was enacted to raise money after the American Civil War. A group of Missouri distillers and farmers known as The Whiskey Ring conspired against the government and bribed officials so they could pocket the taxes themselves. For many, moonshine was the only way to afford liquor or turn a profit on liquor sales.
• Prohibition. Federal alcohol prohibition laws came to the U.S. in 1920. Since liquor was now illegal and very hard to come by, demand for moonshine significantly increased and producers began experimenting with innovative flavors and additives.

What Are the Ingredients in Moonshine?

Traditionally, moonshine is made from corn. However, sometimes moonshiners (a.k.a. people who make moonshine) use rye or barley instead. Yeast, malt, sugar, and water are also added to the mix, with each moonshiner having their own particular preference.

Moonshine was originally popular because it could be created and purchased without paying taxes, but in modern times it’s sought out for its flavor and high alcohol content. Ethanol is the pure alcohol responsible for intoxication in alcoholic beverages. However, the moonshine distillation process creates a toxic byproduct called methanol that can have deadly consequences when consumed.

Moonshine is known for having significantly higher alcohol content than other hard liquors. Vodka, bourbon, and gin, for example, do not generally reach an alcohol by volume (ABV) above 80% alcohol content, and typically rest in the 35%-50% range. Moonshine, however, is often much higher.

The key to moonshine’s high alcohol content lies in the production process. Keep reading to understand how the chemical composition of moonshine makes it up to 95% ABV — and how this can cause blindness or death to consumers if distilled improperly.

               

A Common Mash Recipe Example

The heart of any moonshine recipe is the "mash" — a mixture of grains, water, sugar, and yeast that ferments to create alcohol. Think of it as the base that determines the final character and potency of the spirit. The process starts by creating this sugary, grain-filled liquid. Once the mash is prepared, the real transformation begins with fermentation. This is where yeast is introduced to the mixture to begin converting the sugars into alcohol. While the basic components are simple, the specific ratios and types of ingredients used can dramatically alter the final product, especially when it comes to the two most active ingredients: sugar and yeast.

The Role of Sugar and Yeast

Sugar is the primary fuel for fermentation, and adding more of it is a direct way to create a higher-proof spirit. The impact is significant; for instance, adding eight pounds of sugar to a five-gallon corn mash can increase the final alcohol content by about 9.5%. This is a key reason why moonshine often has a much higher alcohol by volume (ABV) than commercially produced liquors. The type of yeast also matters. While you could technically use bread yeast, most distillers opt for a specialized distiller’s yeast to ensure a more efficient fermentation and a cleaner-tasting result. This careful manipulation of ingredients is what gives moonshine its famously high potency.

How Is Moonshine Actually Made?

The most popular way to make moonshine is using a still. A still is a large, multi-chamber pot used to boil a liquid and extract certain chemicals (such as ethanol). Moonshine, in particular, uses a copper still.

• Fermentation. First, the corn is cooked in water to create a slurry known as a “mash.” Then, it is cooled and mixed with sugar and yeast and left to ferment. The yeast eats the sugar and produces ethanol as a waste product.

• Boiling. After the mash has fermented, it is filtered and transferred into a still, where it is heated to a boil.

• Evaporation. Ethanol has a lower evaporation temperature than water. As the mash boils, alcohol evaporates and is collected in another chamber, where it cools and condenses into a glass jar called a receiver.

• Bottling. The moonshine is then removed from the receiver, filtered, and bottled.

Some moonshiners add flavors or other ingredients at the end, such as sugar, fruit juice, or herbal mixtures. However, these flavor additives may not be the only things hidden inside this insidious liquor.

Step 1: Preparing and Fermenting the Mash

The moonshine-making process starts with creating the “mash,” which is the foundation of the final spirit. Traditionally, this involves cooking corn in water to create a thick slurry. After this mixture has had a chance to cool, sugar and yeast are added. This is where the fermentation process kicks off. The yeast begins to consume the sugars present in the mash, and as a waste product, it produces ethanol—the type of alcohol found in alcoholic drinks. This mixture is then left to ferment for several days in a controlled environment. The goal is to allow the yeast enough time to convert as much sugar as possible into alcohol, creating a fermented liquid known as a “wash” that is ready for the next critical stage: distillation.

Sweet Mash vs. Sour Mash

When it comes to fermentation, distillers can use one of two primary methods: sweet mash or sour mash. A sweet mash involves using a fresh batch of yeast for every new fermentation, ensuring a clean start each time. A sour mash, however, operates more like making sourdough bread. It incorporates a portion of the fermented, acidic liquid from a previous batch (known as “backset”) to start the fermentation in the new one. This technique is common in American whiskey production because it helps maintain a consistent flavor profile and controls the mash's pH level, which prevents the growth of unwanted bacteria. The choice between these methods significantly influences the final character and taste of the spirit.

Step 2: The Distillation Run

Once fermentation is complete, the alcoholic “wash” is filtered and transferred into a still, which is typically made of copper. This is where distillation separates and concentrates the alcohol. The process relies on a simple scientific principle: ethanol has a lower boiling point than water. As the still heats the wash, the alcohol evaporates into a vapor before the water does. This vapor rises and travels through a series of pipes or a column into a separate chamber, where it’s cooled rapidly. This cooling action causes the vapor to condense back into a liquid, which is collected. This new liquid is a much more potent, concentrated form of alcohol than the original wash.

This distillation run is what gives moonshine its famously high alcohol content, but it’s also the most dangerous part of the process. A skilled distiller knows that the first vapors to emerge, called the "foreshots," are full of toxic methanol and must be discarded. The final part of the run, the "tails," contains undesirable oils. The pure, drinkable ethanol is in the middle, or the "hearts." In an unregulated setting, it's incredibly difficult to make these "cuts" precisely. This is why consuming improperly distilled moonshine is so risky—even a small amount of methanol can cause blindness, nerve damage, or death.

How Moonshine Stacks Up Against Other Hard Liquors

The moonshine distillation process is very similar to the process for making other types of spirits. However, a few key details make all the difference.

Moonshine alcohol, when defined as the beverage, is an unaged clear whiskey and made from corn. It can also be up to 95% alcohol, which is much more alcohol content than most hard liquors. Let’s explore how this is different from a few other hard spirits.

• Whiskey generally uses the same ingredients as moonshine, and is typically aged, which produces its signature honey-amber color.
• Vodka is a clear alcohol that, like moonshine, is not aged. Vodka can be produced from grain, fruit, orpotatoes, and is usually distilled several times to remove impurities and other substances.
• Gin is also a clear hard liquor, but gin is made from grain alcohol and juniper berries. Many types of plants and sugars can be used to adjust the process, but juniper berries are fundamental to its definition.
• Tequila is made from agave and produced mainly in certain regions of Mexico. The agave plant is baked in a brick or clay oven called a “horno,” after which juice is extracted from the plant to be fermented, distilled, and aged.

These may seem similar, but the only big thing these liquors have in common is that they are all distilled. The process of moonshine distillation differs just slightly from other liquors, but it makes a huge difference.

Understanding Proof and Potency

The allure of moonshine often comes from its reputation for being incredibly strong. This isn't just folklore; the way it's made is designed to create a spirit with a very high alcohol content. Understanding its potency is key to recognizing the risks involved, especially with illicitly produced versions. The distillation process concentrates the alcohol, but without proper controls, it also concentrates the dangers. This high strength is measured in "proof," a term that's simply double the alcohol by volume (ABV). So, a 150-proof moonshine is a staggering 75% alcohol, which can have a rapid and intense effect on your body.

How Distillation Increases Alcohol Strength

The secret to moonshine’s strength is all in the still. During distillation, the fermented corn mash is heated. Because alcohol (ethanol) has a lower boiling point than water, it turns into vapor first. This vapor travels through a series of pipes or chambers, leaving most of the water behind. As it cools, the vapor condenses back into a liquid — now a much more concentrated form of alcohol. This process is what separates moonshine from drinks like beer or wine and gives it its high proof. A single distillation run can produce a potent spirit, and some moonshiners might even distill it multiple times to make it even stronger, which significantly impacts your blood alcohol content (BAC) much faster than other liquors.

The Traditional “Bead Test”

Long before modern tools were available, moonshiners had a clever way to estimate their spirit's strength: the “bead test.” They would shake a jar of the finished moonshine and watch the bubbles, or “beads,” that formed. If large beads appeared and lingered on the surface for a while, it was a sign of high-proof liquor, likely over 100 proof (50% ABV). If the bubbles were smaller and disappeared quickly, the alcohol content was lower. This simple, visual test gave distillers a reliable, on-the-spot method to test the potency of their product, ensuring it met the expectations of their customers and confirming a successful distillation run.

What Are the Risks of Making Moonshine?

The primary difference between common liquors and moonshine is that careful attention is paid to removing impurities from standard liquor, often with multiple rounds of distillation. By definition, moonshine is typically distilled only once.

Originally, moonshine was illegal due to its association with tax evasion. Even today there are many “illegal” distilleries that create moonshine in secret to avoid taxes, but they are less common because even major distilleries make commercial moonshine.

The danger on moonshine comes from the production process itself. If the distillation process is not done correctly, moonshine can contain high levels of a more toxic form of alcohol: methanol.

Methanol and ethanol (the two types of alcohol produced when making moonshine) are both highly flammable and have the potential to explode during the distillation process. A gas leak between the distillation apparatus and the receiving container could also spark an explosion. Ventilation is important, and illegal moonshine is often produced in non-commercial settings that were not designed with this in mind.

So, is moonshine bad for you? We knowSo, is moonshine bad for you? We know moonshine production can be dangerous, especially when moonshiners are inexperienced and don’t understand the precautions necessary for safety — and unfortunately, drinking it can be just as dangerous. moonshine production can be dangerous, especially when moonshiners are inexperienced and don’t understand the precautions necessary for safety — and, unfortunately, drinking it can be just as dangerous.

Unsafe Equipment and Lead Poisoning

The risks of moonshine aren't just about the alcohol itself; the equipment used in unregulated production can pose a serious threat. Historically, and in some modern illegal operations, stills are built from whatever is available, including old car radiators or pipes joined with lead-based solder. When the acidic alcohol mash is heated in these containers, it can leach lead directly into the final product. Lead poisoning is incredibly dangerous, causing irreversible neurological damage, kidney failure, and other severe health problems. Professional, legal distillers use equipment made from food-safe materials like 304 stainless steel or pure copper to ensure their product is free from such contaminants. This is a critical distinction that separates a craft spirit from a potentially toxic homemade brew.

Explosion and Fire Hazards

The process of distillation involves heating a highly flammable liquid to create an even more flammable vapor. This creates a significant risk of explosions and fires, especially in an amateur setting. Alcohol vapors are dense and can accumulate in poorly ventilated areas, and all it takes is a single spark from the heat source or faulty wiring to ignite them. Furthermore, if a still is sealed completely without a proper vent for pressure to escape, it can essentially become a bomb. The potential for severe burns, property damage, and even death is very real. This is why commercial distilleries operate in controlled environments with strict safety protocols, something that is often overlooked in illicit moonshine operations.

Key Distillation Safety Rules

To manage these dangers, legitimate distillers follow strict safety procedures that highlight the chemical precision required. One of the most crucial steps is to discard the first part of the distilled liquid. This initial output, known as the “foreshots” and the beginning of the “heads,” contains a high concentration of methanol and other volatile compounds like acetone. This toxic type of alcohol is the reason improperly made moonshine can cause blindness or death. Another non-negotiable rule is ensuring proper ventilation to prevent the buildup of flammable vapors. Finally, a still must never be completely sealed; it requires a vent to allow pressure to release safely, preventing a catastrophic explosion. These rules underscore the expertise needed to produce spirits safely.

Why Is Moonshine So Dangerous?

So, what is so dangerous about drinking moonshine? It has a reputation as a dangerous liquor, but the details are not often discussed. As we discussed earlier, methanol is a form of alcohol created during moonshine production alongside the commonly-known ethanol. The differences between ethanol and methanol are molecular, and they impact our body in dramatically different ways.

Can Drinking Moonshine Make You Blind?

Is there any truth to the rumors of “moonshine blindness”? Science says yes, moonshine can indeed make you blind. Humans can tolerate generous amounts of ethanol, but only a few milliliters of methanol will get us extremely drunk, and it only takes a few more milliliters later for methanol to become lethal. Our liver processes methanol into formaldehyde, and later into formic acid. As little as 2 teaspoons (10 mL) of methanol produces enough formic acid to cause blindness.

Because moonshine and methanol are both clear liquids, it’s impossible to tell if it contains any methanol just by looking at it. Commercial moonshine producers have the means to eliminate methanol after distillation, but some illegal moonshiners actually add small amounts of methanol to make the drink stronger.

There is no reliable way to test for methanol content in illicit moonshine. Upon first sip, we simply get really drunk — and we might not know whether or not methanol is responsible.

The Real Danger: Methanol Poisoning

2 teaspoons (10 mL) of methanol is enough to give us the worst hangover of our life, but as we know, any more than that is damaging to our eyesight. For context, one standard shot glass contains about 9 tsp (3 tbsp/44 mL). Drinking too much methanol can result in full or partial blindness. This result is called methanol-induced optic neuropathy, or Me-ION.

Me-ION causes damage to the optic nerve, which connects visual information to our brain for interpretation. Any damage to this nerve behind either eye will result in different types of (or complete) — vision loss.

The lethal dose of methanol is 6 tsp (2 tbsp/30 mL). Some people may not need that much methanol for it to be lethal, either. In facilities where moonshine is still being produced illegally, there is no way of telling how many shots or glasses of moonshine will contain lethal amounts of methanol. Remember: moonshine that is made illicitly may be stronger because methanol has been added.

Our chances of alcohol poisoning are also higher when methanol is present because of how little methanol is needed to get drunk. Not only are we putting ourselves at risk for lethal doses of methanol, but we are also putting ourselves at risk for violent hangovers and alcohol-related experiences when drinking illicitly-produced moonshine. So how do we avoid this?

The Science of Separating Alcohols by Boiling Point

The entire process of distillation hinges on a simple scientific principle: different liquids turn to vapor at different temperatures. Water, for example, boils at 212°F. Ethanol—the type of alcohol we can safely drink—boils at a lower temperature, around 174°F. This difference is what allows distillers to separate the alcohol from the water in the mash. But here's the crucial part: methanol, the toxic alcohol we've been talking about, boils at an even lower temperature than ethanol. This means it's the very first substance to evaporate when the mash is heated, creating a concentrated, dangerous vapor before the desirable ethanol even begins to boil.

Making the “Cuts” to Remove Toxins

Knowing that methanol boils off first is one thing, but actually separating it requires a careful process called making “cuts.” An experienced distiller knows to discard the first part of the alcohol that comes out of the still. This initial portion, known as the “foreshots” and “heads,” is loaded with methanol and other volatile compounds like acetone. This isn't an optional step; it's essential for safety. When you buy liquor from a reputable brand, you can trust that they have meticulously removed these impurities, often through multiple rounds of distillation. With illicit moonshine, there's no guarantee that the producer made the cuts correctly—or at all—leaving you at risk of consuming a toxic cocktail.

The Legality of Making Moonshine

Let's get straight to the point: making moonshine at home is illegal in the United States. It doesn't matter if it's just for you or a few friends—federal law prohibits individuals from distilling spirits without a license. This might seem surprising, especially with the rise of craft hobbies, but the law is very clear on this. The roots of this prohibition go back to the very history we've discussed, primarily revolving around tax evasion. The government has always wanted its cut from alcohol production, and home distilling makes that impossible to regulate. So, while you can legally brew your own beer or make wine at home for personal use, the moment you fire up a still to make spirits, you're crossing a legal line.

This isn't just an old, unenforced law. The Alcohol and Tobacco Tax and Trade Bureau (TTB) is the federal agency responsible for this, and they take it seriously. The penalties for illegal distilling can be severe, including hefty fines and even prison time. The core issue remains the same as it was during the Whiskey Rebellion: taxes. Licensed distilleries pay significant federal excise taxes on the spirits they produce. When someone makes moonshine at home, they are, in the eyes of the law, evading these taxes. This is why even major commercial distilleries now produce their own legal, tax-paid "moonshine," offering a safe and regulated way to enjoy unaged whiskey without the legal or health risks.

Legal Uses for a Still

So if you can't make alcohol, does that mean owning a still is illegal? Not necessarily. You can legally own a still, but what you do with it is what matters. There are several perfectly legal uses for distillation equipment that don't involve making spirits. For instance, you can use a still to purify water or to extract essential oils from plants for aromatherapy or crafting. These activities don't require any special permits. If you're interested in alternative fuels, you can also get a federal permit to distill ethanol for your car. The key takeaway is that the equipment itself isn't the problem; it's the production of untaxed, unregulated alcohol for consumption that is strictly forbidden.

Is It Ever Safe to Drink Moonshine?

Simply put, moonshine made illegally is never guaranteed safe to drink — and “moonshine blindness” is a real possibility! For this reason, it’s probably best to avoid moonshine produced outside of a licensed commercial facility, and it’s definitely best to avoid making our own moonshine.

A high alcohol tolerance may lead us to seek out moonshine for an easier “buzz.” After all, a small amount of methanol will get us more drunk than several glasses of beer, right? But the risks associated with methanol consumption are too great, and we are putting our lives at risk when we decide to drink something with methanol. High tolerance can allow us to handle a little more methanol than a casual drinker, but there’s only so much the human body can handle regardless of how the alcohol content makes us feel.

Thankfully, there are ways to stay safe and avoid the dangers of methanol in moonshine.


• Keep it legal. Stay away from distilleries and moonshiners who don’t have proper licenses! This is a non-negotiable to ensure safety.

• Leave it to the pros. Don’t make moonshine at home, and avoid consuming homemade moonshine even if it’s from a trusted friend or family member. Leave the chemistry to the scientists for this one!

• Stay informed. Educate yourself on small distilleries and alcohol shops before purchasing moonshine. Does the shop or bar have a reputation for distributing alcohol under the radar?

• Consider alternatives. The best way to avoid methanol is to stay away from commercial moonshine and stay away from drinks containing any amount of moonshine.

What to Know Before You Try Moonshine

Throughout history, moonshine has been described romantically as a boozy rebellion to taxation, but now we know it is illegal for a reason — it’s high risk of causing permanent disability. While it may be tempting to try a beverage as strong as moonshine, remember the dangerous consequences of moonshine consumption if it’s not regulated properly. Stay safe and remember: knowledge is power!

Frequently Asked Questions

So, is the 'moonshine' I see in liquor stores also dangerous? Not at all. The spirits labeled as "moonshine" that you find in stores are made by licensed, commercial distilleries. This means they follow strict safety regulations, pay taxes, and use professional equipment designed to remove harmful byproducts like methanol. Think of it as a style of unaged whiskey, not the risky, illicitly made liquor from history.

Why is making moonshine at home illegal if I can brew my own beer? The key difference comes down to one word: distillation. Brewing beer or making wine at home is legal because it only involves fermentation. The moment you use a still to boil a fermented mash and concentrate the alcohol, you're distilling. Federal law prohibits distilling spirits at home without a license, mainly because of tax regulations and the significant safety risks involved in the process.

Can you really go blind from drinking moonshine? Yes, this is a very real danger associated with improperly made moonshine. The distillation process creates a toxic alcohol called methanol as a byproduct. A skilled distiller knows how to separate and discard this, but in an unregulated setting, it can easily end up in the final product. Consuming even a small amount of methanol can cause permanent damage to the optic nerve, leading to blindness or death.

What's the main difference between moonshine and vodka? While both are typically clear, unaged spirits, they start from different places. At its core, moonshine is a type of unaged whiskey, traditionally made from a corn mash. Vodka, on the other hand, can be made from a wider variety of ingredients, including grains, potatoes, or even fruit. It's also often distilled multiple times to create a more neutral and pure flavor, whereas moonshine's character comes directly from its single-distillation grain base.

Is there a way to test homemade moonshine to see if it's safe? There is no reliable way to test for methanol outside of a professional lab. It's a colorless, odorless chemical that mixes seamlessly with the drinkable alcohol (ethanol), so you can't see, smell, or taste it. Old tricks like the "bead test" only estimate the proof, not the purity. Because of this, drinking any unregulated, homemade spirit is a serious gamble with your health.

Key Takeaways

• The Real Danger Is Invisible Methanol: The same distillation process that makes moonshine potent also creates toxic methanol. Without professional equipment and knowledge, it's nearly impossible to separate the safe alcohol (ethanol) from the part that can cause blindness or even death.
• It's Illegal and Physically Dangerous to Make: Federal law prohibits distilling spirits at home, not just for tax reasons, but because the process itself is hazardous. Amateur setups risk explosions from flammable vapors and lead poisoning from unsafe equipment.
• Store-Bought "Moonshine" Is Simply Unaged Whiskey: When you buy "moonshine" from a licensed brand, you're getting a regulated spirit that has been safely distilled to remove all toxins. This is the only version that is ever safe to drink and is fundamentally different from its illicit counterpart.
