Definition

Noun: - Pure ethyl alcohol (ethanol) produced from fermented grains: "Grain alcohol" refers specifically to ethanol that has been distilled from fermented grain mash. It is a clear, colorless, flammable liquid. - A versatile solvent and intoxicant: It is the primary psychoactive component in alcoholic beverages and is also used extensively in industrial, medical, and fuel applications.

Usage Examples
  • Noun:
    • The laboratory uses pure grain alcohol as a solvent for extracting plant compounds.
    • Some homemade liqueurs call for grain alcohol as a base because of its high purity and neutral flavor.
    • The proposal discussed adding grain alcohol to gasoline to create a cleaner-burning fuel.
Advanced Usage

  • "Neutral grain spirit": A high-purity grain alcohol, often used in the production of vodka or gin.

    • The vodka is distilled from a neutral grain spirit to achieve its smooth character.

  • Denatured alcohol: Grain alcohol that has been made unfit for human consumption by adding chemicals, intended for industrial use.

    • Denatured grain alcohol is commonly found in products like shellac and camping stove fuel.
Variants and Related Words

  • Ethanol (n): The systematic chemical name for grain alcohol (C₂H₅OH).

    • Ethanol is a type of alcohol that can be produced from various plant materials, not just grains.

  • Ethyl alcohol (n): A synonym for ethanol and grain alcohol.

    • The formula for ethyl alcohol is C₂H₅OH.
Synonyms
  • Absolute alcohol: Very pure ethanol with minimal water content.
  • Rectified spirit: A highly concentrated ethanol solution produced by repeated distillation.
Related Phrases
  • Proof spirit: A measure of the strength of an alcohol solution, historically related to grain alcohol content.
    • In the past, "proof" was determined by soaking gunpowder with the spirit; if it ignited, it was "proof" it contained enough grain alcohol.
Related Concepts
  • Fermentation: The metabolic process where yeast converts sugars from grains into ethanol and carbon dioxide, the first step in producing grain alcohol.
  • Distillation: The process of purifying a liquid by heating and cooling, used to increase the concentration of ethanol from the fermented mash to create grain alcohol.
  • Biofuel: A fuel derived directly from living matter, such as ethanol (grain alcohol) used as a gasoline additive.
