Approved on 2026-08-24. Direct, visually verified evidence now supports both the grain-formulation definition and the boundary between mash bill and finished whiskey identity.
Definition
The specified grain types and proportions used to formulate a whiskey mash.
Scope
Use this tag when
- Comparing proportions of corn, rye, wheat, malted barley, or other grains in a whiskey formulation.
- Retrieving evidence about grain composition as a production input.
Do not use this tag when
- Classifying a finished whiskey style without discussing grain formulation.
- Describing mash cooking or fermentation procedures.
- Treating a shared mash bill as proof that two whiskeys are identical.
Boundary examples
- Included: A producer’s percentage composition of corn, rye, and malted barley.
- Excluded: A general definition of straight bourbon that does not analyze grain formulation.
Semantic relationship
Parent Topic: Raw Materials and Agriculture
Evidence decision
Bryson’s verified passages at PDF pp. 103 and 105 identify the ingredients and proportions represented by a mash bill and explain why the same mash bill does not determine identical finished whiskey. The term now resolves through Excerpts, a Complete Literature Note, Developing Zettels, and a Supported Claim.
Future review rule
Reopen only if a competing term emerges or the project needs a distinct child for a recurring formulation class. Do not create percentage-specific tags.
