A small sensory or mixture-design pilot can justify conclusions about the tested samples and experimental region, but it cannot establish universal markers, rankings, mechanisms, or optima for an entire whiskey category.
A small study can still provide strong causal evidence for a tightly controlled local effect; the limit concerns generalization, not automatic invalidity.

Method choice, assessor role, target population, comparison set, and tested mixture region define what the result can support; they do not make the pilot useless.
Strengthened on 2026-08-29 with public ASTM and ISO method scopes. The evidence reinforces local-inference discipline but does not supply licensed procedures or justify category-wide claims.
A Zettel is one durable idea in your own words—not a quotation, source summary, or draft-book claim.
Atomic idea
State one complete idea. It should be understandable on its own and specific enough to connect to other notes.
Reasoning
Explain why the idea is true or useful in Rationale and Implications. Record meaningful objections or exceptions in Counterpoints.
Provenance
Connect one or more Literature Notes. Direct source relations are legacy-only; trace evidence through the literature-note and excerpt chain.
Connections
Apply approved Tags for retrieval and one or more Themes only when the note genuinely advances those interpretive threads.

Boundary: this wine-tasting manual contributes attributed teaching observations and hypotheses, not new whiskey trial results. The existing atomic statement and maturity are unchanged.
