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 a thumper 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.
Is it safe to distill alcohol in aluminum?
I have found that aluminum will corrode in the low pH environment of a fermentation. In a distilling environment this can dangerous if you are using the aluminum as a pressure vessel. Its also kind of gross and although not much aluminum will get into your product, its certainly not a selling point.
What are the parts of a still?
Components of a traditional pot still:
- Pot – where the wash is heated.
- Swan Neck – where the vapours rise and reflux.
- Lyne Arm – transfers the vapour to the condenser.
- Condenser – cools the vapour to yield distillate.
What’s the purpose of a thumper on a moonshine still?
The main purpose of the thump keg is to compound the distillation process, which is the process of evaporation that occurs when alcohol turns to vapor as the liquid mash is boiled. Alcohol has a lower boiling point than water, so it will turn to steam and get collected before condensing back into liquid form.
What is the purpose of the thumper in a still?
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 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.
What is a reflux still?
Reflux Still. Unlike pot stills, reflux stills are designed to create higher proof with little to no flavor alcohol. Inside the still is a fractioning column that allows the reflux of liquid to help condense the rising vapor and increase the efficiency of distilling, thus increasing purity.
Is it legal to make moonshine?
Federal Distillation Laws. Federal law states that it is legal to own a still of any size. However, be advised it is illegal to distill alcohol without having either a “distilled spirits permit” or a “federal fuel alcohol permit.” It does not matter if the alcohol is for personal use only, not for sale, etc.
Is Moonshine better than regular alcohol?
There isn’t anything inherently dangerous about moonshine — at least no more dangerous than any other alcoholic drink. When made properly, it is simply very strong alcohol with a very hard taste, or “kick,” because it hasn’t been aged. It is usually very potent, as high as 150 proof, which is about 75 percent alcohol.
How do columns still work?
How Does a Column Still Work? A column still has partitions, or perforated plates, that set up chambers within the still. The mash enters near the top of the still and immediately starts to sink. The mash, at this point, is still low in alcohol, like a beer or wine.
