Neutral grain spirit (also called pure grain alcohol (PGA) or grain neutral spirit (GNS)) is a clear, colorless, flammable liquid that has been distilled from a grain-based mash to a very high level of ethanol content. The term neutral refers to the spirit's lacking the flavor that would have been present if the mash ingredients were distilled to a lower level of alcoholic purity, and also lacking any flavoring added to it after distillation (as is done, for example, with gin). Other kinds of spirits, such as whisky, are distilled to a lower alcohol percentage in order to preserve the flavor of the mash.
The mash from which neutral grain spirit is produced can be any type or mixture of cereal grains.
As a defined standard of identification under U.S. law, "neutral spirits" or "neutral alcohol" are distilled spirits produced from any material at or above 95% alcohol by volume. Such a product made from grain is "grain neutral spirit," while such a spirit made from grapes is called "grape neutral spirit," and so on. When the term is used in an informal context rather than as a term of U.S. law, any distilled spirit of high alcoholic purity (e.g., 170 proof or higher) that does not contain added flavoring may be referred to as neutral alcohol.
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.
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.

“The United States must be neutral in fact as well as in name.... We must be impartial in thought as well as in action ... a nation that neither sits in judgment upon others nor is disturbed in her own counsels and which keeps herself fit and free to do what is honest and disinterested and truly serviceable for the peace of the world.”
—Woodrow Wilson (1856–1924)
“Grow your tree of falsehood from a small grain of truth.
Do not follow those who lie in contempt of reality.
Let your lie be even more logical than the truth itself,
So the weary travelers may find repose.”
—Czeslaw Milosz (b. 1911)
“Young men are as apt to think themselves wise enough, as drunken men are to think themselves sober enough. They look upon spirit to be a much better thing than experience, which they call coldness. They are but half mistaken; for though spirit without experience is dangerous, experience without spirit is languid and defective.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
