Simultaneously, a heat exchange occurs in the thump keg where the vapor cools.
There will not be any distillate until the temperature gets high enough for the compounds to vaporize.
This has everything to do with the bubble size, the depth of immersion and the volume of alcohol in both the vapor and the thumper liquid.
What is inside a thump keg?
Some moonshiners use a thump keg, which is simply a heated barrel into which the steam is forced. The worm box is a crate or barrel that has cold water, usually diverted from a nearby creek, flowing into the top and then back out the bottom.
Why do you need a thumper for moonshine?
Traditional copper pot stills use a thumper or thump keg to increase proof (improve purity). In the thump keg, the liquid is essentially re-distilled before it is condensed back into a liquid. Because the addition of a thumper effectively distills alcohol twice during one run it’s sometimes referred to as a “doubler.”
What is the purpose of a thumper?
Basically, a thumper keg is a container that is installed in the distillation apparatus between the still pot and the condenser. It was traditionally used in hillbilly stills to increase the alcohol content of the distillate because, traditional stills only output product with about a 50-60 percent alcohol content.
What is a thumper on a still?
Some moonshine stills have a “thumper” or “doubler” between them and the condensor. This is a jar of sorts, half-filled with liquid (water, mash or tails). See the Moonshine Photos for examples of them. Thumper. This acts as a simple second distillation stage.
Why is moonshine illegal?
Moonshine is any illegally made distilled alcohol. Classically it is corn liquor distilled from fermented corn and / or sugar. Distilling alcohol without state and federal permits is illegal in every single state in the US. Making moonshine is illegal because the government wishes to collect tax revenue.
What does moonshine taste like?
Vodka has a milder taste. I think moonshine smells closer to turpentine than it does to vodka. But both have mostly the flavor of the alcohol dominating the taste. Bourbon is a whiskey made with at lease 51% corn, but it has been aged in oak which imparts a lot of the bourbon flavor.
