Historic whisky work directly supports measured iterative blending and cautions against equating threshold multiples with intensity. Model wood extraction and fermentation findings must remain bounded to their systems.

Source And Scope
J. R. Piggott and A. Paterson, editors; Ellis Horwood / VCH, 1989; symposium held at Stirling in June 1988. Mixed evidence: overview chapters and primary experimental reports. The database's book-level Secondary label does not erase the primary character of individual experiments. Supplied scan has 364 PDF sheets; main printed page = PDF sheet minus 11. Full-document OCR is for retrieval; equations, figures and numeric tables need original-image checks before reuse. Whole contents screened, with selected chapter openings and close reading below. Not an every-page audit.
High-Value Evidence
Williams, chapter 23, printed pp. 251–255 / PDF 262–266: sequential Simplex trials use a taster's acceptance scores to select another formulation in a constrained three-component space. The illustrated example is explicitly theoretical; claims about six to eight assessments do not establish reproducibility, a global optimum or broad consumer acceptance. Figure 1 and page 253 were visually checked. Use the idea to guide small, measured trials and confirmation on another occasion; do not promise an automatic perfect blend.
Perry, chapter 18, pp. 200–207 / PDF 211–218: thresholds and suprathreshold intensity slopes are different quantities. The eight-compound comparison uses 23% ethanol and butanol matching; equal threshold multiples need not yield equal intensities. Dilution of two spirits at constant ethanol strength changes congener concentration and perceived aroma character. This is not the same treatment as adding water to whiskey. Single-compound intensity estimates are not a validated whole-whiskey flavor model. The conclusion that masked damascenone must have a very small intensity index is an inference, not a separately demonstrated index in that experiment. Do not import its historical constants into the calculator.
Guy, Piggott and Marie, chapter 4, opening/methods/results pp. 41–45 / PDF 52–56: consumer free-choice descriptions and a trained vocabulary need different handling. Ninety-three usable responses from 100 recruits illustrate real attrition. Appearance strongly tracks one mapping dimension in this sample set; preserve color/blinding conditions and avoid treating a perceptual map as an objective quality map. The full chapter's figures and later interpretation were not exhaustively audited.
Maga, chapter 14, pp. 171–176 / PDF 182–187: wood origin, storage, charring, ethanol concentration, pH and exposure time were varied in a model system. The reported 40% ethanol/pH 3.5 extraction maximum applies to the tested conditions, aged sapwood and months-long contact; it is not a universal optimum for barrel entry, drinking proof or glass blending. Historical cis/trans labeling and quoted threshold values require reconciliation with original cited studies and the Library's existing stereochemistry warnings before numerical reuse. No threshold values from this chapter are imported.
Geddes and Riffkin, chapter 17, pp. 193–199 / PDF 204–210: controlled lactobacillus treatments changed some acid/ester and acetaldehyde outcomes. Effects varied with fermentation conditions; some data are not shown and panel detail is limited. This supports teaching that upstream biological processes shape composition, not that adding acids or resting a finished blend recreates fermentation. The paper's broad “essential” quality conclusion is stronger than a universal claim warranted by its small systems.

Blending Lab Recommendation
Begin with a two-component ratio ladder, record actual quantities and a baseline, then retest the favorite under new codes. Three-component exploration can follow as a proposed exercise. Keep the tested region, actual ABV preparation, person and session visible. The recommended exercise is a USWA adaptation, not a validated reproduction of the chapter's software algorithm.
Connections And Teaching Use
No access — chemistry explains mechanisms and model assumptions; these sensory methods test what people perceive.
Sensory Evaluation Techniques — Methods, Critical Corrections And Academy Applications — extend the existing sensory-methods synthesis rather than replacing it.
Whisky dilution changes both headspace chemistry and discrimination — Ashmore et al. — connect dilution and headspace evidence while retaining the study's sample and method limits.
No access — proposed teaching and product requirements; not implemented software.
Teach one question, a small coded comparison and a clear conclusion in the Short Version. Use the Full Story for the mechanism, controls, source locations and uncertainty.
Integrated Recommendations
