If the whiskey burned off and the powder ignited, it was considered “proof.” That meant approximately 100 proof (49.5 percent rounded up).
But now we know a number of factors change the flash point—when the alcohol will ignite, not necessarily burn steadily.
It’s not really the liquid burning.
What color does moonshine burn if it’s good?
A common folk test for the quality of moonshine was to pour a small quantity of it into a spoon and set it on fire. The theory was that a safe distillate burns with a blue flame, but a tainted distillate burns with a yellow flame.
Does moonshine burn blue?
Folklore tells us one way to test the purity of moonshine is to pour some in a metal spoon and set it on fire. If it burns with a blue flame it is safe, but if it burns with a yellow or red flame, it contains lead, prompting the old saying, “Lead burns red and makes you dead.”
Can you test for methanol in moonshine?
Methyl alcohol (methanol) is the bad stuff that could be found in moonshine. Pure methanol is very dangerous and it is definitely able to cause blindness and even kill people. As little as 10 ml of pure methanol could blind someone and as little as 30 ml could kill someone.
At what proof does alcohol burn blue?
The basic rule of thumb is anything 80 proof or above will light, and the higher the proof, the easier the alcohol will be to ignite. The 80-proof rule means all your basic liquors will light: tequila, rum, whiskey, vodka, please step forward.
Why does my moonshine smell bad?
Contagion with methanol can be noticed by the bad smell and taste of your moonshine and needs to be avoided, since it is toxic. Now, if you successfully made your moonshine alcohol, here are is how you properly ensure that the process went well and that you, in fact, made good moonshine: 1. First, smell it.
