Is there a home test for methanol?
How to Test If Alcohol Has Methanol Updated May 23, 2018 By Blake Flournoy Methanol is an alcohol much like ethanol, which is the active ingredient in alcoholic beverages. Methanol provides the same buzz as ethanol, and occurs naturally at low levels in fermented drinks but is far more toxic than ethanol, to the point that it can cause severe illness and death.
- Commercial producers of alcohol have specialized methods of removing methanol from their products, but home and hobby brewers tend not to have the technology at their disposal to easily remove the substance from their brews.
- At the same time, illegal breweries will sometimes use methanol as a cheap substitute for ethanol.
Luckily, there are ways to test for the presence of methanol in an alcoholic beverage. Though similar to ethanol, and capable of providing the same buzz, methanol is a toxic substance and should not be consumed. In trace amounts, as found in certain fermented drinks, it is not harmful, but in larger quantities it can be deadly.
- Alcoholic drinks containing methanol will sometimes have a pungent odor and will produce a yellow flame when lit on fire.
- For a safer test, you can apply sodium dichromate to a sample of the beverage.
- Though methanol is an alcohol similar to ethanol, it is incredibly dangerous in large quantities.
- While methanol does form in small amounts during fermentation and is fine to consume in things like commercially produced wine or beer, the concentration you find in things like home brewed gin, rum and other spirits can poison you.
Unlike ethanol, when consumed, methanol in the human body is converted into formic acid. The same substance found in ant venom. A buildup of formic acid resulting from this can cause circulation problems, liver damage and a number of other symptoms up to and including nerve damage, permanent blindness and kidney failure.
- If you suspect that an alcoholic beverage may contain a dangerous amount of methanol, there are a number of quick and crude tests you can perform.
- The easiest is to smell the beverage: If it has a strong, unpleasant chemical odor, the beverage may not be safe to consume.
- However, because not all methanol-tainted beverages produce this smell, it is also possible to test with flame.
If a sample of the beverage is lit on fire, and the fire burns yellow rather than blue, the drink is not safe to consume. Testing alcohol by scent or by flame are neither guaranteed nor safe methods, however, to test for the presence of methanol more effectively, you can apply sodium dichromate to a sample of the beverage.
- To do so, mix 8 mL of a sodium dichromate solution with 4 mL of sulfuric acid.
- Swirl gently to mix, then add 10 drops of the mixed solution to a test tube or other small container containing the alcohol.
- Swirl this container gently a few times, then waft the air from the mouth of the container towards your nose by fanning the air toward you with a hand, with the container placed roughly 8-12 inches from your face.
Take note of the scent: If it is pungent and irritating, methanol is present in the alcohol. If the scent is dominating and fruity, only ethanol is present, and the beverage is safe. : How to Test If Alcohol Has Methanol
What proof is good drinking moonshine?
Moonshine Proof Range – There are no hard and fast rules for how high the proof of moonshine should be. During the Prohibition era, bootleggers made moonshine ranging from 63 proof through to 190 proof. However, most commercial moonshines are between 60 to 120 proof (30% to 60% ABV). Flavored moonshine is usually even lower at 50 to 70 proof (25% to 35% ABV).
What is a substitute for a hydrometer?
Refractometers – Another popular tool for measuring sugar content is the Refractometer, The refractometer does not work by measuring the density of the liquid. It works by measuring the refraction of light through the liquid and calculating the sugar content based on that measurement.
Do I need a hydrometer?
Why Do You Need A Hydrometer? – You don’t absolutely need a hydrometer, but it’s a great tool to have for brewing. By using it, you can:
Accurately determine how much sugar is in your must or wort (the mixture that you start your fermentation with) Check to see if your brew is still fermenting, or if it has stopped or stalled Calculate the final amount of alcohol in your brew
Think of it like your car’s gas gauge–you can get around without it, but it will definitely make your life easier!
What is the difference between hydrometer and hydrometer?
Hygrometer or hydrometer? Peter Childs, University of Limerick, investigates words in chemistry. In this issue: hygrometer or hydrometer? Do you know the difference between a hygrometer and a hydrometer? A hygrometer measures humidity, the amount of water vapour in air. A hydrometer, on the other hand, measures the density or specific gravity (SG) of a liquid by floating in the liquid. The word hygrometer is derived from the Greek hygros meaning wet or moist, whereas hydro- comes from the Greek for water, hydro (as in hydrated and hydrogen).
Is a hydrometer reusable?
Of course, we also pride ourselves on giving you products – no Lead, no mercury for you to worry about! To top it all off, we made our Hydrometer reusable and easy to clean, so it’s great for an amateur winemaker or a craft brewer!
Is my hydrometer accurate?
Hydrometer Correction and Calibration – It is very important to note that hydrometers are calibrated to be used in a liquid of a certain temperature. Older hydrometers were typically calibrated to 59-60°F, and newer ones can go up to 70°F. The calibration of your hydrometer will be in its instructions.
You want to temperature of the liquid to be at this exact calibration temperature to get an accurate gravity reading. If you can’t, you can use an equation or chart to correct for the temperature of your sample. Detailed information on temperature correction, including the equation and charts, can be found in this Zymurgy article “.” You may also want to verify the calibration of your hydrometer, as it is not uncommon for them to be off.
To do this, take a sample of distilled water at the temperature of the hydrometer’s calibration. If the hydrometer reading is 1.000, your instrument is correctly calibrated. If it is too high, you can use a file to shave off some of the glass from the bottom of the hydrometer until it hits 1.000.
How can you tell if alcohol is proof without a hydrometer?
Download Article Download Article Testing for alcohol content is an important part of home-brewing to determine the potency of your drinks. While most people will use a hydrometer to check the alcohol levels, you can also use a refractometer, which measures how light bends through a liquid to determine the density.
- 1 Buy a refractometer online to measure alcohol content. Refractometers are cylindrical devices that measure the concentration of sugar in water based on how light refracts through the solution. Look at home-brewing websites to see what refractometers they have available to purchase.
- Refractometers usually cost $30 USD or more. More expensive models tend to be more accurate than cheaper ones.
- You may be able to find refractometers in specialty home-brewing stores.
- In order to use a refractometer to measure alcohol content, you need to take a measurement before it begins fermenting. You will not be able to measure alcohol content in a drink otherwise.
- 2 Put 2–3 drops of distilled water on the refractometer’s glass and shut the lid. Flip open the plastic cap on the end of the refractometer to expose the glass underneath. Use a pipette to apply a few drops of distilled water on top of the glass, making sure they don’t run off. Flip the plastic lid closed so it spreads the water evenly over the surface.
- Avoid using water from a sink since it may have additives that could affect your reading.
- 3 Hold the refractometer up to your eye so it points at a light source. Put the refractometer’s lens against your eye and point the other end with the glass toward a light, such as a lamp or ceiling light. As you look through the lens, you will see a scale of numbers ascending vertically and the background will have a white section near the bottom and a blue section above it.
- The horizontal line that splits the blue section and the white section in the background is the hydrometer reading.
- If you have a digital refractometer, it will have a light built into the body so you don’t need an external light source.
Tip: If you can’t read the numbers on the scales, rotate the eyepiece to focus the image.
- 4 Adjust the calibration screw if you don’t have a 0 reading on the scale. Check where the horizontal line crosses the scales. If it doesn’t line up with the 0 mark on either scale, locate the calibration screw on the top of the refractometer. Use a screwdriver to turn the screw counterclockwise if the line is above the 0 mark or clockwise if the line is above it.
- The calibration screw may be covered by a plastic cap so you don’t accidentally rotate it while using the refractometer.
- The refractometer may already come with a screwdriver.
- 5 Wipe the glass dry to prevent damage. Flip the lid open on the refractometer and use a lint-free microfiber towel to dry off the glass. If you aren’t able to clean off all the water with the towel, leave the lid open and allow the refractometer to air dry so it doesn’t affect future readings.
- Avoid leaving water or moisture on the refractometer since it could leak into the machine and make it inaccurate in future readings.
- 1 Put 2–3 drops of the unfermented sample on the refractometer. Use the sugar and water starter liquid, or wort, you’re using for your homebrew and pull a small sample into a pipette. Open the plastic lid on the refractometer and apply 2–3 drops across the glass. Close the lid to help spread out the drops into a thin, even layer.
- Refractometers work best for measuring alcohol in home-brewed beer or whiskey.
- You can try using a refractometer to measure must, which is crushed fruit used for wine, but you may not get as accurate of a reading.
Tip: Many refractometers automatically adjust for temperature, but if your model doesn’t, wait until the unfermented sample reaches room temperature before taking your measurement. If you don’t, you may get an inaccurate reading.
- 2 Hold the refractometer up to a light to find the Brix gravity reading. Place the refractometer’s lens against your eye and point the glass toward a light source. Rotate the lens to adjust the focus if you’re not able to see the scales clearly. Look at the scale labeled “Brix %” and note where the horizontal line crosses it. Write down the reading so you don’t forget it later on.
- The Brix scale usually goes from 0 to 30%, but it may vary depending on the model of your refractometer.
- You do not need to use the side labeled “SG” or “Specific Gravity” since it will be more difficult to convert later on.
- 3 Take another Brix reading 2–3 weeks after the liquid starts fermenting. Wait until the solution or wort begins fermenting before taking your next measurement, or else you won’t be able to get an accurate measurement. Place another 2–3 drops of the wort onto the refractometer’s glass and close the lid.
- You can take your second reading at any point during the fermentation process.
- 4 Divide both of your readings by 1.04 to correct them. Since refractometers have slight inaccuracies to them, take the readings you found and divide them by 1.04, which is the standard correction value. Write down the final results you found out rounded to the second decimal place so you have the initial and final Brix percent measurements.
- For example, if the initial Brix percentage was 12 on the refractometer, the equation would be: 12/1.04 = 11.54.
- If you found the final Brix percentage was 8, then your equation would be: 8/1.04 = 7.69.
- 1 Plug the readings into the correction formula for the final specific gravity. Use the formula: 1.0000 – (0.0044993 * IB) + (0.011774 * FB) + (0.00027581 * IB²) – (0.0012717 * FB²) – (0.0000072800 * IB³) + (0.000063293 * FB³), where IB is the corrected initial Brix measurement and FB is the corrected final Brix measurement.
- For example, if the corrected initial Brix percentage was 11.54 and the corrected final percentage was 7.69, the equation would be: 1.0000 – (0.0044993 * 11.54) + (0.011774 * 7.69) + (0.00027581 * (11.54²)) – (0.0012717 * (7.69²)) – (0.0000072800 * (11.54³)) + (0.000063293 * (7.69³)).
- After plugging the equation into a calculator, the final specific gravity would be 1.018.
- 2 Convert the first Brix reading with (IB / ) + 1. Plug the corrected initial Brix percentage into the equation in place of IB and enter the formula into your calculator. Round your answer to the third decimal point to find the initial specific gravity, which you can use to find the alcohol content of the wort.
- For example, if the first Brix percentage was 11.54, the equation would read: (11.54 / ) + 1.
- When you plug the equation into a calculator, you would find the initial specific gravity is 1.046.
- 3 Use (76.08 * / ) * (FG / 0.794) to find the alcohol content. Plug the initial specific gravity you just calculated in for IG and the final specific gravity you found earlier in place of FG. Type the equation into a calculator and round the answer to the third decimal point to find the expected alcohol content of the wort once it’s completely fermented.
- For example, if the initial specific gravity was 1.046 and the final specific gravity was 1.018, then the equation would read: (76.08 * / ) * (1.018 / 0.794).
- After putting the formula into a calculator, your result would be 3.747, which means the drink will be 3.747% alcohol by volume, which is how much alcohol is contained in 100 millilitres (3.4 fl oz).

How can I check my alcohol percentage at home?
All we need is a digital thermometer (accuracy 0.1OC or higher). Measure the difference in boiling point of wine (or beer) as compared to that of deionized water. Higher the alcohol content, lower the boiling point is. Use a degree ebulliometer reference table to compute the alcohol percentage.
