You are watching: Can you go blind from moonshine

January 20, 2013 Methanol - will certainly Moonshine do You Blind?

Moonshine and also Blindness

We acquire a many questions about how to distill safely. Among the most frequent questions we get is "can moonshine make you blind?" The brief answer is this: as soon as made in tiny batches while complying with a couple of simple safety and security precautions, moonshine will NOT reason blindness, death, or also a poor hangover. 

In the write-up below we"ll explain what could cause moonshine to make someone walk blind and we"ll likewise explain just how to be absolutely, positively, 100% sure that this won"t happen.

Methanol Toxicity

Methyl alcohol (methanol) is the bad stuff that can be found in moonshine. Pure methanol is an extremely dangerous and it is certainly able to cause blindness and also even kill people. As little as 10 ml the pure methanol might blind someone and also as small as 30 ml could kill someone. 30 mililiters is tantamount to the quantity of fluid in a standard shot glass.

How is Methanol Produced?

Methanol is uncovered naturally in particular fruits and also vegetables. It may also be produced as an unintentional byproduct throughout the fermentation process. Soul distilled native fruits, such as apples, oranges, and grapes, are an ext likely come contain methanol. Both beer and wine typically contain methanol. Studies have established that wine deserve to contain as lot as 329 mg/L and also beer might contain somewhere on the order of 16 mg/L. This provides distilled alcohol (grappa, brandy, etc.) potentially much more dangerous 보다 all serial shine - such as corn whiskey.

Why is Methanol A concern for Moonshiners?

If wine includes methanol however doesn"t attitude a hazard of methanol poisoning then why is it potentially dangerous come drink once distilled? The difference is the the methanol concentration in, say, 5 gallons of wine, is same distributed among the 5 gallons. Because that someone come ingest a potentially dangerous amount they would need to ingest more than 5 gallons....or 28 bottles! 

During the distillation process methanol is focused at the start of the run since it has a reduced boiling allude than ethanol and water. The boiling suggest of methanol is approximately 148 degrees farenheit, which is quite a little lower than ethanol (the an excellent stuff). This way that methanol (148F boiling temp) will start to boil before the ethanol (174F boiling temp). This is why moonshiners always throw the end the an initial bit of light they produce from each run (more on this below).

Here space a couple of examples that the dangers that methanol:

If 5 gallons of wine containing the abovementioned concentration the methanol (329mg/L) were distilled, there might be as lot as 8 mL the methyl alcohol in the first jar - a perhaps dangerous amount.Scale this as much as a 100 gallon batch, distilled every at the same time in a large still, and also you might potentially have a very big problem if the methanol was not discarded. Distilling 100 gallons of wine containing 329 mg/L of methanol could an outcome in the concentration of 40ml the methanol, which might be deadly if someone drank it every at once.

How to remove Methanol from Moonshine

One method to determine the visibility of methanol is to monitor still temperature. If anything is produced by the still before wash temperature reaches 174 degrees, it"s methanol. Discard it. Again, methanol boils in ~ a reduced temperature 보다 ethanol and will concentration at the start of distillation runs. Additionally, competent distillers have determined that merely discarding a traditional amount per batch, based upon batch size, is enough to save things safe. The preeminence of ignorance is come discard 1/3 the a pint jar because that every 5 gallons of wash being distilled.

How lot initial product come discard:

1 gallon batch - discard the very first 2/3 the a shooting glass5 gallon batch - discard the an initial 1/3 the a pint jar10 gallon batch - discard the very first 3/4 of a pint jar

Regardless of tho temp, it"s a an excellent idea to always follow this ascendancy of thumb. Methanol or not, the first stuff to come turn off the tho tastes and smells choose rubbing alcohol. It"s by much the worst stuff in the whole run and also it isn"t walking to impress anyone. If you drink it, it can not death you or make you go blind, yet it"ll surely add a fair amount in the direction of a nasty hangover.

I have a “friend” who I had actually heard that successfully developing shine / fuel multiple times by utilizing advice uncovered in your site, as well as others. As soon as my “friend” developed the light he never ever seemed to gain a methanol, or acetone drip during the heat develop up. I….. I average my “friend” slowly…very slowly brings the warm up come 172 Fahrenheit. In the 4 gallons that mash gift heated, it takes my “friend” around 75 minute to reach the desired variety of temperature. The an initial 150 ml are gathered and put aside to be disposed. Because that curiosity benefits we… i mean, my “friend” closely takes a teaspoon of very first 150 ml and also puts one ignition resource to it. Each and also every time he sees a blue flame. He has never, ever seen a yellow, or orange flame, (which is supposed to indicate the existence of toxins). Mine guess is that as result of the slow-moving buildup of warm the methanol and also acetone evaporate. The foreshot, or head never ever does smell toxic. Granted, that doesn’t odor as great as the love of the body…but I inquiry if, in fact I’m throw away an excellent product. Wait, correction… If mine "friend"is cram away an excellent product.Can girlfriend tell me that my theory is correct regarding the methanol is just evaporating because of the slow heat buildup?


My inquiry is same as the one above, is there methanol current on consecutive runs or simply on the first and also is a blue flame a good way come tell if I have actually drinkable product.


Kris june 13, 2018. The mash % transforms the starting boil temp. Your far better off using plenty of jars to find the ethenol. Distill a second time and also start approximately 35% (so friend dont punch up) to watch a boiling temp the is closer to the charts here.


my tho does not begin to condensate the spirit before temperature reaches around 87 Celsius. I carry out not obtain a single drop the spirit prior to that point. I therefore do not know all the hullaballoo around methanol. Can someone you re welcome amplify?


I made some mash it’s corn sugar water and also yeast the fermented fine yet I was wondering deserve to I frozen distill it and also drink it and not worry about methonal or is it no safe come drink?


Now xxx way how many times you run it with the still therefore does that way i need to repeat this proccess after each run, or only on first run since first batch is native mash and also twice an ext is from shine : 5 gallon batch discard the first 1/3 the a pint jar.

QUESTION to be ASKED around WHAT TO execute WITH THE TAIL—- IF YOU usage A THUMPER usage IT TO charge YOUR THUMPER following RUN— will PULL last OZZZIE the ALCHOHOL the end OF IT


HI I compose from Brazil, and I’m make the efforts to do schnapps (I think it’s the German variation of Moonshine), yet I’m worried around methanol. Do you know if over there is any type of kind of chemistry I use to prevent methanol, or is the solution just staying clear of the head?


If you simply read the clawhammers’ instructions, and do a little research around what you room trying to accomplish with her shine, friend will acquire excellent results, that’s what ns did and my very first run net me a gallon or 150 evidence corn whiskey. You also need patience, i m sorry is why started this in the first place, as result of my lack of patience, it’s a procedure that can’t it is in rushed, you literally acquire out what you put into it. HAPPY SHINING!!!!


I have discarded methanol < head > and also I have actually stored the heart and tail. I execute not understand what to carry out with the " tail "


Hey all my family lived on the hill in front of popcorn shutton. Castle made much more shine than he ever before did . Ns am walking to obtain them to teach me however I do know this they use white corn sugar spring water no yeast however if u usage yeast u want to usage it while the is still working just pass high point an usage vinegar water come clean all copper parts I need to ask them on remainder ty.
