About Neutral Grain Alcohol

Neutral Grain alcoholNeutral grain alcohol, which is also known as grain neutral spirit (GNS) or pure grain alcohol (PGA), is a flammable, colorless and clear liquid which has been distilled from mash that is grain-based to where it holds a high content of ethanol. It is described as neutral because the spirit lacks flavor which is usually present when the mash ingredients are distilled to the point when the alcohol purity is lower; in addition it does not have any added flavor after it has been distilled, which is usually done with gin. Other spirits, including whisky, are distilled for lower alcohol percentage to preserve the mash’s flavor.

Neutral grain alcohol can be produced from mash comprised of any mixture or type of grain cereals.
