Use Bryson 2025, PDF p. 11, for the American-whiskey framing and Kosar 2010, printed pp. 12–13 / PDF sheets 14–15, for independent enumeration of material and process variables. Reigler, PDF sheets 36–38 and 147–148, is consumer-facing corroboration only.

Bryson’s framing at PDF p. 11 and Kosar’s production overview at printed pp. 12–13 / PDF sheets 14–15 were visually verified. Reigler's chain overview and Four Roses recipe comparison were also verified, but her individual technical mechanisms are not controlling. The wording intentionally avoids assigning equal or quantitative shares to stages.
This does not mean every stage contributes equally to every whiskey or every sensory attribute.
Bryson states that flavor and aroma are made or removed at every step. Kosar independently lists water, yeast, grain, still mechanics, distillation, cask characteristics, warehouse microclimate, and careful execution through bottling as contributors to the final product.
Pilot-era title normalized in Batch 025. LOCAL-023 adds secondary illustration without changing Ready for Drafting/Strong/High status. Fresh Proof source audit: full supplied text read, evidence locators rechecked. Malting develops/activates enzymes and modifies grain; bulk starch conversion occurs in subsequent mashing. Correct acrospire/rootlet anatomy before teaching. Reported copper intervention and cited experiment are different evidence types; the complete relocation difference remains unresolved. This source-specific audit does not independently reverify other linked works or increase claim confidence.

American whiskey’s sensory character is formed and edited across multiple production stages rather than being attributable to one stage alone.
Evidence
Bryson provides the direct American-whiskey framing. Kosar independently enumerates water, yeast, grain, still mechanics, distillation count, cask variables, warehouse microclimate, and execution from grain preparation through bottling.
Boundary
The evidence does not mean that every stage contributes equally to every whiskey or sensory attribute.
Drafting guidance
Use the chain as an organizing structure for production chapters, then show where particular styles or compounds are dominated by specific stages.
Readiness decision
Ready for Drafting with Strong evidence and High confidence across two independent sources.
Reigler 2020 — source-contribution audit
Reigler PDF36–38 supplies a consumer-facing chain overview; PDF147–148 describes a guided recipe comparison with supplied sensory descriptors. This supports illustration of the multistage framework, not measured stage contributions or experimental causal isolation. The source's technical simplifications do not override specialist evidence.
Other-source evidence and existing claim status retained; this audit does not independently reverify every linked work or published use.
