Use Arnold pp. 23 and 205 for the threshold spectrum, Martini p. 337 for multi-stage provenance, and Hannush p. 138 for the historical authenticity-control case.
A regional whiskey designation can refer to different provenance thresholds, from in-state bottling to in-state distillation and aging to locally grown grain.
Arnold pp. 23 and 205, Martini p. 337 / PDF sheet 51, and Hannush p. 138 / PDF sheet 152 were visually verified.
This classifies possible thresholds; it does not claim that local grain is always necessary for a legitimate regional identity.
Arnold contrasts labels based only on bottling with rules requiring in-state distillation and aging, then identifies Empire Rye’s local-grain requirement as a stronger geographic connection.
Established across three independent sources and periods. Old Robertson adds historical evidence that regional provenance was economically contested long before modern certification. September28 fresh Arnold review: associated passages rechecked against enlarged source pages. This checks Arnold's contribution only; other linked sources retain their own audit history.
Evidence judgment
Arnold distinguishes bottling, distillation and aging, and local agricultural input as different geographic thresholds. Martini’s Texas case shows why one stage cannot represent the whole contribution chain. Hannush’s 1865 Old Robertson episode demonstrates the practical consequence: once a regional name had value, falsely stamped whiskey appeared and producers created an authorized channel.
Synthesis
A regional name is informative only when the production contribution and authenticity mechanism behind it are explicit. Thresholds may be descriptive rather than prescriptive, but the reader should be able to tell what the place contributed and why the origin claim is credible.
Drafting guardrail
State the relevant stages and evidence. Do not infer grain-to-glass provenance from a state name, bottling address, one production step, or an uncontrolled regional label.
