Use multiple practitioner sources to explain flexible forms. Greene, displayed p. 194 / PDF sheet 31, adds an explicit Old-Fashioned architecture; displayed p. 197 / sheet 34 adds base-spirit-led design. Exact historical priority and bar-specific versions still require their own provenance.

Existing practitioner passages remain verified. Greene’s two new supporting passages were rechecked in the partial Kindle attachment at PDF sheets 31 and 34, displayed pp. 194 and 197, during a complete review of all 105 available sheets.
A historical recipe, bar specification, or named variant may require exact reproduction. Not every substitution preserves identity.
Across independent practitioner sources, canonical drinks preserve functional relationships while proof, water, sweetness, acidity, spirit, garnish, and service vary. Schmid's historical sequence shows why form-level continuity and version-level precision must be recorded separately.
Ready for Drafting / Strong / High remains appropriate. Greene independently strengthens both the durable-form model and the rule that the base whiskey’s sensory profile constrains ingredient choice. The evidence does not make every substitution valid or settle origin history.

Canonical bourbon cocktails are most useful to the website as flexible forms rather than immutable recipes.
Evidence
Multiple independent practitioner sources document stable functional relationships alongside bounded changes in ingredients and service. Schmid adds an especially compact Old Fashioned case: the 1806 structural grammar, an explicit preferred specification, a dated 1885–1917 recipe sequence, and later disagreements over water, ice, fruit, garnish, glass, and technique.
Qualification
Use exact, attributed specifications when reconstructing a historical recipe or evaluating a named bar's version. Not every substitution preserves identity, and form-level continuity does not prove invention or priority.
Drafting guidance
Teach the form first. Then present dated versions with creator or source, ingredients, proportions, method, vessel, and service so the reader can see what changed.
Verification
Ready for Drafting with Strong evidence and High confidence. The Schmid source was fully reviewed at 76/76 sheets and 4/4 contact sheets.
