Alcohol distillation is a heat-dependant process used to purify or separate alcohol mixtures. This process is used in the manufacture of such alcoholic beverages as brandy, whiskey and rum. These beverages, also known as spirits, are made by first preparing a mash of grains or fruit juices. The mash is fermented, that is, natural sugars in the grain or fruit are converted to alcohol by microscopic yeast. Then the fermented mash is heated in a boiler, causing the alcohol to evaporate. The alcohol vapors are collected and then cooled in a condenser to produce the alcoholic beverage. Distilling is done with a still, either a pot still or a column still. A pot still produces one batch of liquid at a time and is a simple still that can be set up and used at home. A column still permits distillation to occur continuously...
