I was wondering if anyone here knows anyone whom may or may not have distilled some alcohol at one time or another.

I found this site from a member here can't find the name.

this site is devoted to distilling Ethanol but the section on can you drink it is a little too ambiguous for one to be certain of the safety.

On the "can you drink it" page i found a link to distilling drinking alcohol based in NZ.

Here is the link to download the entire site.

I hope someone finds that useful.

So anyone here have any knowledge they would be willing to share?

I have distilled alcohol on a small scale a few times. I was fortifying cheap vodka up to 140 proof to try making mushroom tincture. This is easy to do and avoids the toxic compounds problem. I used my pc with a 1/4" copper pressure fitting, ran a 2 foot copper tube to a water jacketed condenser I silver brazed up out of copper tubing and fittings. (That was not easy)

When distilling from scratch the wash contains all sorts of stuff from the fermentation. When the wash is distilled some decomposition in the wash takes place and produces poisonous compounds. Methanol for one. Other compounds are produced that taste bad.

These poisonous compounds distill over first because they have a lower boiling point than ethanol. Traditional style distillers would collect the first runnings and discard the stuff. The rest of the run will be clean spirits. When the rate of distilling slows the ethanol is distilled off and the amount of water going over increases. Time to quit.

A better still will have a vertical column with a tube tapped in somewhere near the top of the column. A thermometer is placed at the top of the column. The initial temperature of the distillation will be a few degrees cooler because of the poisonous compounds. When the temperature increases then poison is gone and good spirits are running over. This temperature should be kept as low as possible if you are trying to get a high proof spirit. This is done by lowering the boiling as much as possible. End point is found when the temperature increases.

Methanol boils at 65 C. Ethanol boils at 78 C. Water boils at 100 C. You do not want to collect any distillate below 78 C. Distillate collected closest to 78 C will have a higher proof. The closer to 100 C the lower the proof. A spirit that passes proof can moisten black powder and the powder will still burn. I think that is at around 80 proof.

Running the alcohol through activated charcoal might smooth the stuff a bit.

This site has a great deal of info on the subject of fermentation and distillation:
