I always thought the reason was that badly distilled drinks were dangerous.
Distillation doesn’t create alcohols, it only concentrates them. The ratio of ethanol to methanol in a distilled spirit will be approximately the same as in the wash it was distilled from. Drinking brandy you’ll get about the same ratio as if you drank the wine it was made from.
You need the same amount of ethanol to get drunk regardless of how you drink it, all distilling does is get rid of that pesky water that’s in beer and wine. (That makes some other fun things like barrel aging possible.) So you’ll also get the same amount of methanol.
Also fun fact: if you got methanol poisoning and went to the hospital the treatment is ethanol, because it blocks the metabolism of methanol. Methanol metabolizes into formic acid which damages the optic nerve.
And contrary to lore, mass spectrometry shows that the idea that methanol comes off the still first (meaning that if you collected the early results, called heads, and drank them, you might get too much) is false or at least drastically oversimplified.
You’d have to try hard to seriously injure yourself drinking home distilled spirits. (I’ve been doing it for 15 years.) Unless you count just drinking too much, but you’d have that problem with the professional stuff too.
This is wrong. The boiling point of methanol is 65C vs ethanol at 78C. Methanol will come out first from distillation.
Oversimplified might be a better description but there needs to be a rule even dumb people can use
So the rule is: discard whatever comes first
If you expect every home distiller to understand the nuances of this you're going to end up with a lot of "accidents"
And, later on in distillation, when you’re much closer to the boiling point of water than ethanol, there will still be some ethanol coming out.
I get why you think that, I did too before diving deeper, but I assure you, your mental model of how distillation works is incorrect.
That says nothing about the remains of the input. When removing methanol we are trying to get it out of the input side. So while the output will indeed contain both, that doesn't mean the input will still have any methanol.

When you get into distilling you learn pretty fast that a lot of what you’ve been told about it is fake due to both deliberate propaganda, and the fact that a lot of it was learned before we had scientific tools to investigate deeper.
You would pretty much have to try to poison yourself distilling and yet everybody thinks it’s a real risk.
Being poisoned by a bootlegger who adds methanol because it’s cheaper (much like fentanyl in opiods) is not a fake risk, and a lot of people who think the first thing happened actually had the second thing happen.
And I’m certainly not criticizing people for this, I went to school for physics and yet was on the other side of this debate when I started distilling before I did research.
And even if you just distilled until it was basically water coming out, then re-blended everything, you have not significantly worsened the ratio of the two
how did that work? did the Feds pose as some false flag bootleggers? do you have some sources I could read up on?
thing is, russia has a large tradition of home distillation (samogonka), and they too have tropes of people going blind. there have been a lot of cases of people dying because of bad alcohol, here's somewhat recent case: https://www.cbsnews.com/news/contaminated-cider-deaths-russi...
It’s quite common for people to add methanol to illegal liquor because it can be made cheaply from natural gas and is sold industrially everywhere. You are much more likely to be injured buying bootleg alcohol than making it.
North Americans probably have some cultural hangover from Prohibition about the dangers of small-scale distillation. Methanol in particular is probably overstated as a danger. Methanol poisoning seems to mostly happen from adulteration, often with what is mistakenly thought to be industrial ethanol. It is produced at very low levels by fermentation (less than 0.1%) and so at the home distillation scale there's not enough in one batch to be a significant concern. Fire, however, is a genuine risk.
I find it interesting that you have this notion. I was born in 1984. The history books in school were still implying that home distillation was dangerous. "Rot gut whiskey" "bath tub gin" are phrases that continue to come to mind when I think of the prohibition days.
No one I have ever met in all of the different levels of society here have had any strong disdain or distrust of home brewing or distillation. By the time of my upbringing, at least, the general population in the US was content with the alcohol laws. They are not aware of how easy home brewing, wine-making, and distilling are. They are not aware of the post prohibition three tier system. They are consumers of alcohol not producers. That is what prohibition in the US did. "House wine" in the US is the wine a restaurant picks for cheap profits. "House wine" in the old days or in europe is wine you make at home. We, in general, lost that piece of culture with prohibition. It never disappeared in some parts of the country though. Appalachia moonshiners kept the tradition going in mind and spirit for the whole country.
If your statement was about other drugs, you would be spot on. Prohibition regarding alcohol was not accepted by almost every demographic strata. Prohibition of other drugs is a different story for cultural reasons.
It's very difficult to ban something when even the police do it. I'm guessing that the number of cops who like a drink is somewhere around "most".
They're not technically complex, but you need space and time for them, and producing a beer you would actually want to drink and bottling it isn't trivial.
I know one guy who moonshines for family-and-friends consumption, not sale, and I'll pass. It's not that much cheaper than just buying it (note: my state alcohol taxes are not that high) and it's a lot more work. I might make a batch of wine -> brandy from fruits that grew on a tree in my back yard if I had plums, just to say I did, but I'm not interested in making a big batch of corn liquor.
Anyway, my point is that the people most at risk of poisoning themselves are those unfamiliar with the process. I'm pretty sure a ton of people were doing this anyway for non-commercial purposes without realizing an unenforced federal law even existed.
Having said that, fake booze in Thailand has killed and blinded people so it’s not risk free
The much bigger danger for home distilling is fire, as you have open flames and combustible vapor. The fire codes for a distillery are very strict.
This would suggest that using induction heating would be significantly safer and have the possibility of precise temperature control. Is there any reason why home distilling does/does not do this?
(Technically there actually isn’t temperature control in distilling, the temperature is just the boiling point of the mixture, which changes over time as the mixture changes from distillation, but you do control the heat input which effects the speed at which you distill. Tangential, but counterintuitive.)
The reason most don’t is just cost/practicality. You really need to have a fair bit of liquid to get good results. Like tenish gallons (~40L). You probably can’t fit a still that big on your stovetop (and you really want to do this outside anyway) and you’d need a 240v connection to provide enough heat. Your standard American wall outlet doesn’t provide enough juice.
But the standard 240v 50a you charge an EV with or, in my case, plug in your RV does. People run drier cords out a window too.
Ah, that would do it. I was thinking this was like beer homebrewing and would be around a gallon.
Thanks for the info.
Then you get the heads, hearts, and tails and blend them together according to taste. You just wouldn’t get much separation if you distilled a small amount unless you were collecting in really tiny quantities.
So it just becomes harder to do a good job with a small amount.
So, just like you won't go blind from a bottle of brandy, you won't go blind from distilled wine. However, you're likely to have a serious headache the morning after.
The only exception was a methanol affair 15 years ago, but that had nothing to do with home distillation. In that particular case, two bozos inspired by a badly understood Wikipedia article bought and mixed enormous amounts of industrial methanol with ethanol and sold the resulting mixture on the black market, killing dozens of people and triggering a temporary prohibition as the authorities scrambled to find all the poisoned booze.
They are now both serving life.
Same could be said about food: dishes, knives etc. Anyway the high temperature should kill some of the germs.
> the precursor fruits could be half rotten
So what?
We also had some cases of crap being sold, but that's a different thing.
A colleague from the region explained to me that if the booze is cheap, you just make sure you drink plenty of good booze too. Blocks the metabolic pathway.
normal hooch is dangerous, too.
