A whiskey grain is a process material as well as a flavor input: starch structure, gelatinization, enzyme access, viscosity, and retrogradation determine the cooking and conversion conditions it requires.
Grain chemistry constrains but does not uniquely determine a viable process; multiple treatment strategies may reach acceptable conversion.
Mash bills should be evaluated with their treatment system. A grain percentage cannot be interpreted independently of milling, cooking, enzymes, solids, temperature, and equipment.
Created from the complete SRC-21 review and connected to the secondary-conversion mechanism. Fresh SRC-341 audit: Fireman is retained as attributed practitioner context, not independent validation of this mechanism. The supplied224-page review found material arithmetic, unit, biological and engineering errors; use the other linked technical sources for the mechanism.
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.
