Build a small comparative flight by matching grain-defined style and subcategory, minimizing production and cask differences, using aroma-concentrating glassware, optionally blinding brand and color, normalizing samples to the same ABV, and recording orthonasal aroma, taste, retronasal aroma, and finish.
This database describes whiskey-domain processes such as mashing, fermentation, distillation, maturation, blending, proofing, and tasting. Book-production procedures belong in Publishing Processes.
Process definition
Build a small flight that improves comparability among commercial whiskeys without claiming to isolate terroir.
Inputs
- Three or four whiskeys from the same grain-defined style and a narrow subcategory.
- Product and producer information sufficient to compare grain bill, cask type, age, proof, and known production variables.
- Matching Glencairn, Copita, or other narrow aroma-concentrating glasses.
- Water, a measuring cylinder or pipette, coded labels, and optional blue glass or a blind pourer.
- A consistent tasting form.
Sequence
- Choose one style and subcategory: for example, ryed bourbon versus ryed bourbon, high-rye versus high-rye, or peated malt versus peated malt.
- Exclude obviously incomparable cask, grain-bill, or maturation treatments when the purpose is ingredient or place comparison.
- Research remaining differences in mashing, yeast, fermentation, distillation, maturation, filtration, and blending.
- Use identical clean glassware. Blind brand and color when expectation control matters.
- Normalize samples to the same ABV when practical, using (C_1V_1=C_2V_2). Mix consistently and allow the same rest time.
- Record expectations before tasting, then assess orthonasal aroma, taste, retronasal aroma, finish, and overall preference as separate observations.
- Compare observations only after each sample has been independently assessed.
Output
A comparative sensory record with the controlled variables, known residual confounds, sample strengths, serving conditions, and separate observations for difference and preference.
Evidence
Arnold supplies the consumer-scale workflow in Appendix 1, especially printed pp. 302–304. The equal-ABV step also connects to the existing Proofing whiskey for bottling or tasting process.
Review gate
This process improves discipline but does not prove agricultural causation in commercial bottles. Do not label a difference “terroir” when yeast, fermentation, distillation, maturation, or blending remain plausible explanations.
