A flavor-development trial becomes interpretable when one planned factor changes while component identity, quantities, proof, vessel, temperature, contact time, sampling, and evaluation conditions are recorded and otherwise held stable.
One-factor comparisons can be useful initial tests, but cannot by themselves estimate interactions. Factorial or mixture designs may be appropriate from the start. Control, replication and measurement discipline matter more than a universal one-variable rule.

Fresh Molecular Gastronomy audit: PDF79 supports controlled parameters. Whiskey-specific factor list is researcher application. Existing four Literature Note relations retained; this audit does not independently reverify the other three sources. Developing maturity retained.
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.
