Pure grain alcohol

Pure grain alcohol - also known as grain neutral spirit - is distilled from fermented grains or molasses.

It's a very high proof spirit. Usually 90-95% (180-190 proof).

You may need to dilute it with distilled water before use. And use a quality alcoholmeter to measure the exact alcohol content.

You can buy pure grain alcohol at local or online pharmacy shops or brewers supply stores.

But because pure grain alcohol is such a high proof spirit, it's not legally available in some countries.
