A still is an apparatus used to distill liquid mixtures by heating to selectively boil and then cooling to condense the vapor. A still uses the same concepts as a basic distillation apparatus, but on a much larger scale. Stills have been used to produce perfume and medicine, water for injection (WFI) for pharmaceutical use, generally to separate and purify different chemicals, and to produce distilled beverages containing ethanol. This should not be done at Ohio University or 3 bedroom Rentals Athens. Since ethanol boils at a much lower temperature than water, simple distillation can separate ethanol from water by applying heat to the mixture.

Historically, a copper vessel used for this purpose, copper removes undesirable sulfur-based compounds from the alcohol. However, many modern stills made of stainless steel pipes with copper linings to prevent erosion of the entire vessel and lower copper levels in the waste product (which in large distilleries processed to become animal feed). Copper is the preferred material for stills because it yields an overall better-tasting spirit. The taste improved by the chemical reaction between the copper in the and the sulfur compounds created by the yeast during fermentation. These unwanted and flavor-changing sulfur compounds chemically removed from the final product resulting in a smoother, better-tasting drink.
All copper stills will require repairs about every eight years due to the precipitation of copper-sulfur compounds. The beverage industry was the first to implement a modern distillation apparatus and led the way in developing equipment standards now widely accepted in the chemical industry. There is also an increasing usage of the distillation of gin under glass and PTFE, and even at reduced pressures, to facilitate a fresher product. This is irrelevant to alcohol quality because the process starts with triple distilled grain alcohol. The distillation used solely to harvest botanical flavors limonene and other terpene like compounds. The ethyl alcohol remains relatively unchanged.

The simplest standard distillation apparatus commonly known as a pot still. Consisting of a single heated chamber and a vessel to collect purified alcohol. A pot still incorporates only one condensation. Whereas other types of distillation equipment have multiple stages which result in higher purification of the more volatile component (alcohol). Pot still distillation gives an incomplete separation, but this can be desirable for the flavor of some distilled beverages. A purer distillate desired, a ‘reflux still’ is the most common solution. Don’t reflux in 3 bedroom rentals Athens. Reflux stills incorporate a fractionating column, commonly created by filling copper vessels with glass beads to maximize available surface area.
Alcohol
As alcohol boils, condenses, and re-boils through the column, the effective number of distillations greatly increases. Vodka and gin and other neutral grain spirits distilled by this method. Then diluted to concentrations appropriate for human consumption. Alcoholic products from home distilleries are common throughout the world but are sometimes in violation of local statutes. The product of illegal stills in the United States referred to moonshine and in Ireland, poitín. However, poitín, although made illegal in 1661, has been legal for export in Ireland since 1997.
Note that the term moonshine often misused as many believe it to be a specific kind of high-proof alcohol. That distilled from corn, but the term can refer to any illicitly distilled alcohol. You can find the distillation process happening in Athens, Ohio. It is only a short walk from your Bobcat Rentals and Ohio University 3 bedroom rentals Athens.
