If you love your moonshine, you might be curious about the distillation process and want to try it yourself. You’ve probably also heard horror stories about people who get sick and even die from methanol poisoning. To distill moonshine without any methanol, you must discard the first portion of your distillate containing poisonous compounds.

How do you prevent methanol when distilling alcohol?
How to Avoid Methanol When Distilling Alcohol Making your own spirits at home is not only interesting, but also a great learning experience. However, preparing any alcoholic beverage by yourself calls for the right care and precision. How is Methanol Produced? Also known as methyl alcohol or wood spirit, methanol is the simplest (shortest chain) of alcohols which is one-part carbon, one-part oxygen and four parts hydrogen.
Methanol is commonly produced commercially from coal, natural gas, and other renewable sources such as recycled carbon dioxide, biomass, and municipal waste. Initially, it was produced by performing a destructive distillation of wood, but nowadays it’s produced from synthesis gas by combining hydrogen and carbon monoxide with the help of a catalyst.
Apart from that, methanol is also produced in small amounts during the process of alcohol distillation. It is produced at the initial stages of the process and is tossed out by the distillers. This biodegradable form of alcohol is an organic water-soluble chemical.

- How to Minimize Methanol in Fermentation?
- When making alcohol at home, it’s the fermentation stage that produces methanol.
- The amount produced will vary with different conditions, including the temperature, the type of yeast and other bacterial in the solution, the type of food you provide to them, the minerals, and more.
- Normal fermentation of starch-derived sugars from corn, wheat, and barley will only contain very small amounts of compounds that will turn into methanol during fermentation.
- A couple of general rules to minimize methanol when distilling are:
- Be more wary of methanol when distilling fruits, as opposed to sugar washes, grain washes, or whiskeys.
- Brandy made from distilled fermented grapes will have a lower methanol content than schnapps (fruit brandy) made from fermented apples, or citrus.
- Remove pectin from the food sources you are using, or simply go for items that don’t contain pectin. This prevents microorganisms from producing methanol.
- Use high-quality, reliable yeast.
- Make sure to control the temperature and don’t let it go too high during fermentation.
- Sterilize everything before fermentation to kill harmful bacteria.
Can you Test for Methanol in Alcohol? Yes! You can test for the presence of methanol in an alcoholic beverage by performing some quick tests. The Smell Test Smelling the beverage is the easiest methanol test yet one that takes a lot of practice to hone your senses.
- If you sense an unpleasant chemical odor from the solution, the drink is not safe for consumption.
- Methanol has a sharp, stinging scent that is quite potent and can be easily recognized as ‘the smell of alcohol’ Ethanol will smell much milder by contrast.
- It’s softer, less stingy, and almost has a ‘creamy’ aroma.
Ethanol won’t smell as potent as methanol of the same concentration.
- Compared to methanol, ethanol will smell very pleasant – but it’s very hard to tell if you’re not comparing the two side by side.
- The Flame Test
- Take a small sample of the alcohol solution and light it on fire – if you witness a yellow fire instead of a blue flame, the solution contains methanol.
Again, this test is good in theory, but in practice you’ll seldom be comparing two solutions that are entirely methanol or ethanol. They will be blended and of varying proportions. Also, be very careful setting things on fire as distilling is a potentially explosive process. Keep any open flame well away from a running still.
- The Chemical Test
- A more effective test for methanol in alcohol is to apply sodium dichromate to a small sample of the solution.
- All you need to do is mix 8 mL of a sodium dichromate with 4 mL of sulfuric acid, further swirling the mix and adding 10 drops of the same to a small container or a test tube containing the alcohol to be tested.
Gently swirl test tube, followed by using your hand to fan the air from the opening of the test tube towards your nose while you hold the tube 10-12 inches from your nose. Notice the smell – if it’s unpleasant and pungent, then the alcohol contains methanol. However, if it seems fruity, the beverage contains only ethanol and is safe for consumption. : How to Avoid Methanol When Distilling Alcohol
How do you remove methanol from distilling?
How to separate methanol in distillation – Methanol is more volatile than ethanol under all operating conditions adopted by distilleries, so it is possible to separate it by distillation as “heads” or “head product”. In the case of a batch distillation plant, we separate methanol using an appropriate choice of head-cut timing.
- The longer the timing of the cut, the more methanol is removed, but in the process some of the “heart” is lost.
- It is therefore essential to find the balance between maximum methanol removal and maximum amount of heart produced.
- In a continuous column or plant it is possible to take a stream of “heads” rich in methanol, taking it from the reflux of the column.
Since in these plants the distillate is usually at higher alcohol concentrations than in a batch plant, and the methanol purity specifications are often more stringent, a demethylating column is often used. While in the demethylating column we have the distillate stream at high alcohol concentration.
- Inside it, the separation between methanol (head product) and ethanol (tail product) takes place.
- Because of the similar volatility rate of methanol and ethanol, the tail product (demethylated distillate) will contain traces of methanol in concentrations below the required specifications, whereas the head product, rich in methanol, will contain significant quantities of ethanol.
The latter percentage of ethanol is a by-product of distillation. It should be recovered to avoid waste and improve the overall efficiency of the distillery.
What removes methanol?
How to Cope with Methanol Intoxication – To date, most of the strategies developed for treating methanol intoxication are based on published clinical reports. A methanol level of ≽ 20 mg/dl is considered as a recommended threshold for treating methanol poisoning.
Diagnostic approaches that are most efficient in detecting methanol poisoning include: History and physical examination Taking a history of the type and duration of exposure and physical examinations of initial signs and symptoms. Serum osmolal gap Higher osmolality indicates alcohol accumulation in blood.
Serum anion gap Serum anion gaps indicate formic acid or lactic acid accumulation in blood. Gas or liquid chromatography Measuring the concentration of methanol in blood. Liquid-based saliva test This test detects methanol concentration in saliva. The primary aim of any methanol intoxication treatment is to prevent methanol metabolism and/or remove methanol and its toxic metabolites from the body.
- Treatment regimens that are mainly employed to achieve this goal include: Inhibition of methanol metabolism This is achieved by oral or intravenous administration of an alcohol dehydrogenase inhibitor.
- This treatment does not require hospitalization and has minimal side effects.
- Since ethanol competes with methanol for the binding to alcohol dehydrogenase with much higher affinity, it can also be used to prevent methanol metabolism.
However, infusion of ethanol should be continuous and must be performed in an intensive care unit. Hemodialysis Hemodialysis is very effective for removing methanol and its toxic metabolites from the body. This technique is particularly effective for patients who are exposed to methanol for a long duration.
Can you drink a small amount of methanol?
Cause – Methanol has a moderate to high toxicity in humans. As little as 10 mL of pure methanol when drunk is metabolized into formic acid, which can cause permanent blindness by destruction of the optic nerve,15 mL is potentially fatal, although the median lethal dose is typically 100 mL (3.4 fl oz) (i.e.1–2 mL/kg body weight of pure methanol).
Can homemade moonshine make you sick?
Other Side Effects Of Moonshine – Methanol vaporizes faster and can become concentrated in toxic amounts. With the right equipment, it can easily be separated and tossed out. But, without it, the methanol is difficult to discard. The dangerous part happens when the body converts methanol to formaldehyde, which is an ingredient in embalming fluid.
What does drinking methanol feel like?
Nineteen people in Costa Rica have died after consuming alcohol tainted with harmful levels of methanol. The Costa Rican Ministry of Health has confirmed that out of these fatalities, 14 were men and five were women, all were between the ages of 32 and 72, and occurred across various cities in Costa Rica,
- The U.S. Department of State confirmed that no U.S.
- Citizen’s illness or death has been related to the consumption of adulterated alcohol in Costa Rica.
- All victims identified so far have been Costa Rican, and did not consume the alcohol at hotels.
- The health ministry has confiscated about 30,000 containers of alcohol labeled as Guaro Montano, Guaro Gran Apache, Star Welsh and Aguardiente Molotov, after identifying toxic levels of methanol in them.
They have advised the general public to avoid consuming these alcoholic beverages until further investigations are completed and the sources of counterfeit products have been found. Costa Rica President Carlos Alvarado Quesada tweeted out last Friday that he has instructed authorities to continue gathering data in order to identify the sources responsible for these deaths.
While Costa Rica is now making headlines, in recent years there have been numerous outbreaks related to tainted alcohol in Cambodia, Czech Republic and Ecuador, among other countries. Some outbreaks have affected as many as 800 victims with mortality rates greater than 30%, according to the World Health Organization,
In India, 154 people died and over 200 were hospitalized this year alone after drinking unregulated moonshine. Methanol poisoning typically occurs due to the consumption of “adulterated counterfeit or informally produced spirit drinks,” according to the World Health Organization,
- Here’s what you need to know about tainted alcohol and how to avoid being a victim of methanol poisoning.
- Methanol is a widely available chemical that is used in everyday household products.
- Methanol, otherwise known as methyl alcohol, has many industrial applications and can be found in household items such as varnishes, antifreeze, and windscreen wash.
Methanol is also found in things we consume – trace amounts are found naturally in fruit juices, fermented alcoholic and non-alcoholic beverages at non-toxic levels. Low concentrations of naturally present methanol are not harmful, but higher concentrations may be toxic.
- Since methanol is a product of fermentation, low levels of methanol are detected in all beer and spirits, but these low concentrations are not toxic when consumed.
- Harm can be incurred when distillation processes are ill managed, or more commonly, methanol is deliberately added to alcoholic beverages and methanol levels exceed 10-220 mg/L.
When ingested, the body metabolizes methanol into formaldehyde and formic acid, which in large amounts are toxic and even fatal. Methanol levels in the blood exceeding approximately 500 mg/L is toxic if left untreated. The onset of methanol poisoning symptoms do not appear immediately after alcohol consumption.
- Methanol poisoning symptoms take a while to surface.
- The consumed methanol must be metabolized, and toxic levels of formic acid must accumulate in the body.
- In the first few hours, a person will experience drowsiness, feel unsteady and disinhibited.
- Eventually these symptoms will escalate into a headache, vomiting, abdominal pain and vertigo.
Patients may also hyperventilate or feel out of breath, and even experience convulsions, and permanent visual impairment. Most victims seek medical care after a significant delay, which contributes to the high level of morbidity and mortality. Misleading bottle design, labeling, and cheaper prices often cause consumers to unknowingly purchase and consume tainted beverages.
Unregulated, illegal production and distribution of alcoholic drinks takes place worldwide. Cheaper alcohol is particularly attractive to low-income consumers and people who are alcohol dependent. Tourists visiting foreign bars, shops and vacation spots with high alcohol consumption are also at a higher risk.
The main objective of treatment is to prevent further metabolism of methanol. If you suspect someone is a victim of methanol poisoning seek immediate medical help. Ethanol or fomepizole administration, intubation, or mechanical ventilation are the primary forms of treatment.
These are meant to prevent further metabolism of methanol and rapidly remove methanol from the body. You can protect yourself from methanol poisoning. Avoid purchasing or producing illegal alcoholic drinks and be cautious when purchasing alcoholic beverages at informal settings or from vendors who are not licensed to sell alcohol, especially if it is being sold at suspiciously cheap prices.

Do all alcoholic drinks contain methanol?
Methanol is an alcohol that is found in all distilled beverages (such as tequila, whiskey, mezcal, etc.) in different proportions. This alcohol is considered an unavoidable compound in distilled beverages, since it is formed from the fermentation of pectins originating from the raw material with which the distillate is produced.
In more detail, methanol is generated by the demethylation (removal of a methyl group) of the pectins present in the raw material of the distilled beverage. Excessive hydrolysis (breakdown of molecules in aqueous solution) can cause problems with methanol, increasing its amount in the product; otherwise, poor hydrolysis prevents the production of methanol, but causes a loss of sugar from carbohydrates (1),
