Use the method citation together with the four-observer profile citation. Reigler, PDF sheet 40 and sheets 147–148, adds observer-variation and suggestion examples.

Moderate evidence from hospitality-oriented and consumer-facing methods, not controlled sensory studies. Reigler's examples were visually verified; sensory-science corroboration is still required before elevating confidence.
Structured panels and controlled protocols can improve repeatability. This claim does not make sensory analysis arbitrary or useless.
The guide's four blind professional bartenders often describe the same whiskey differently; the Knob Creek Rye profile provides a compact example of material disagreement.
Created after complete textual and visual review of LOCAL-048 on 2026-08-26. LOCAL-023 adds independent practical corroboration. Understanding Bourbon Whiskey adds an attributed distinction between objective/analytical and subjective/hedonic tasting at PDF sheets 63–64. Status remains Supported/Moderate. Fresh Proof source audit: full supplied text read, evidence locators rechecked. Separate preference, discrimination, identification and descriptive analysis. Shared vocabulary requires reference calibration and performance checks; context effects do not invalidate sensory science. This source-specific audit does not independently reverify other linked works or increase claim confidence.

PDF40 describes individual palates;147–148 describes a guided tasting with supplied descriptors. Record observer, sample and prompting conditions. This is practical illustration rather than experimental validation, and it does not imply that trained descriptive panels are inherently arbitrary or incapable of repeatable findings.
Other-source evidence and existing claim status retained; this audit does not independently reverify every linked work or published use.
