Neutral grain spirit (also called pure grain alcohol (PGA) or grain neutral spirit (GNS)) is a clear, colorless, flammable liquid that is distilled from cereal grain and has a very high ethanol content. The term neutral refers to the fact that it lacks any flavor derived from the mash used to distill it, nor does it have any flavor added to it after distillation (as is done, for example, with gin). The grain from which it is produced can be any of the common cereal grains. Other kinds of spirits, such as whisky, are distilled at lower alcohol percentages in order to preserve the flavor of the mash. The purity of neutral grain spirit has a practical limit of 190 proof because a mixture of ethanol and water becomes an azeotrope at 95.6% ABV (191.2 proof). Neutral grain spirit is only one type of neutral spirit (also called neutral alcohol). Neutral alcohol can also be produced from grapes, sugar beets, sugarcane, or other fermented plant material. In particular, large quantities of neutral alcohol are distilled from wine, a product that is referred to as vinous alcohol.[1] Generally, any distilled spirit of 170 proof or higher that does not contain any added flavoring is considered to be neutral alcohol.[2] Neutral grain spirit is used in the production of blended whiskey, cut brandy, some liqueurs, and some bitters. As a consumer good, it is almost always mixed with other beverages to create such drinks as punch and various cocktails, or to produce homemade liqueurs.
Availability in market areasBecause of its high alcohol content, neutral grain spirit is illegal, unavailable, or difficult to find in many areas. Canada
United StatesEverclear, Golden Grain Alcohol, and Gem Clear are three brands of neutral grain spirit sold in the United States.

Rectified spirit“Rectified spirit” or “rectified alcohol” is neutral alcohol which has been purified by means of “rectification” (i.e., repeated distillation). It will contain at least 95% ABV. It is normally used for medicinal purposes but can also be used to make homemade liqueurs. It can be a grain spirit or can be made from other plants. Cultural referencesIn the 1964 film Dr. Strangelove (directed by Stanley Kubrick), base commander General Jack D. Ripper states that he only drinks pure grain alcohol with distilled water or rainwater. See also
