About a century ago during Prohibition, people cooked up moonshine with jury-rigged equipment to fly under the radar of the law. But today, a new generation of craft distillers are making moonshine—high-proof, unaged whiskey—for the masses. In the latest episode of Speaking of Chemistry, we explore the chemicals that put the “fire” in “firewater” and visit a local distilling operation to see and taste how modern chemistry has changed the production of this potent spirit.

I think you mean Jerry-Rigged.

Actually, they were right.

"Jury-rigged" is entirely correct. "Jerry-built" has an entirely separate origin and slightly different meaning.

Very well presented video on "The chemistry of modern Moonshine". The list of low boilers, that make up the Heads portion of the distillate, which contains iPrOH invites, however, a comment. iPrOH itself has a higher boiling point than EtOH, and a mixture of the two alcohols is very difficult to separate by normal distillation. Here we are, of course, concerned with the ternary azeotrope of iPrOH, EtOH, and water, which apparently has a lower boiling point than the azeotrope of EtOH with water.

I thought so, too! But it is jury-rigged, according to Merriam Webster: https://www.merriam-webster.com/dictionary/jury-rig

Great video, very interesting and well-made!

For 12 years I have been a craft distiller at Ryan & Wood in historic Gloucester, MA. This video is the best I have seen and an excellent presentation of the process. Good choice utilizing Kerri Jansen and Ryan Hendricks.Cheers,Bob Ryan

Great video. Been tasting shine for years, especially when aged over peaches, cherries, apples, etc. It's called Fruit, and it is sooo smooth.

Interesting stuff. Where do (now, and maybe in the old days) the amylase enzymes come from? In beer, they occur in the malting of the barley, but I don't think barley is involved here.

Hendricks told us KO Distilling uses both natural enzymes from malted grain, and also commercial enzymes derived from thermophilic bacteria, which can withstand higher temperatures than the natural enzymes and speed up the process. So it's a mix of modern technology and more traditional methods.
