Pure grain alcohol

Rectified spirit, also known as neutral spirits, rectified alcohol, or ethyl alcohol of agricultural origin is highly concentrated ethanol which has been purified by means of repeated distillation, a process that is called rectification. In some countries (e.g. India), denatured alcohol or denatured rectified spirit may commonly be available as "rectified spirit", but this is poisonous and ingestion can be fatal.

It typically contains 95% alcohol by volume (ABV) (190 US proof). The purity of rectified spirit has a practical limit of 95.6% ABV when produced using conventional distillation processes, because a mixture of ethanol and water becomes a minimum-boiling azeotrope at this concentration.

Neutral spirits can be produced from grain, corn, grapes, sugar beets, sugarcane, tuber, or other fermented plant material. In particular, large quantities of neutral alcohol are distilled from wine. Such a product made from grain is "grain neutral spirit", while such a spirit made from grapes is called "grape neutral spirit", or "vinous alcohol".

Neutral spirits are used in the production of blended whisky, cut brandy, some liqueurs, and some bitters. As a consumer product, it is almost always mixed with other beverages to create such drinks as punch, or is sometimes added to cocktails in place of vodka or rum and is used in Jello shots. It is also used to make homemade liqueurs, such as limoncello, and in cooking because its high concentration of alcohol acts as a solvent to extract flavors. Rectified spirits are also used for medicinal tinctures, and as a household solvent. It is sometimes drunk undiluted, however as the alcohol is very high-proof, overconsumption can cause alcohol poisoning more quickly than with more traditional distilled spirits.
