A feature cannot uniquely identify a production process when the same feature can arise through a plausible alternative process.
A nonexclusive feature may still inform a probabilistic judgment. The historical methods and results are not independently authenticated here.
The period report describes finding proposed direct-fire products in steam-jacket spirit and furfural in grain whisky. Preserve the observation while revising the inference; ask what distinguishes the rival explanations.
Atomic idea
A feature cannot uniquely identify a production process when the same feature can arise through a plausible alternative process.
Reasoning
The period report describes finding proposed direct-fire products in steam-jacket spirit and furfural in grain whisky. Preserve the observation while revising the inference; ask what distinguishes the rival explanations.
Located evidence
Original synthesis from a historical source as reproduced in a modern compilation; no claim of independent experimental confirmation.
Library connection
Sensory resemblance does not establish category membership
Counterpoint
A nonexclusive feature may still inform a probabilistic judgment. The historical methods and results are not independently authenticated here.
Whisky Words — complete-volume qualification, 29 September 2026
Full-volume reading preserves the25–27counterexample. A steam-jacket result weakens exclusive direct-fire attribution; it does not itself prove malting as the sole cause. Period analytical methods and source dependence remain limitations.
Existing atomic statement, maturity and prior evidence are retained.
