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 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...
