Neutral grain spirit

Extracted from the Wikipedia article Rectified spirit.
Neutral spirits can be produced from grains, corn, grapes, sugar beets, sugarcane, tubers, or other fermentable materials such as whey. In particular, large quantities of neutral alcohol are distilled from wine and by-products of wine production (pomace, lees). A product made from grain is "neutral grain spirit", while a spirit made from grapes is called "grape neutral spirit" or "vinous alcohol". These terms are commonly abbreviated as either GNS or NGS.
