Independent corroboration for the existing Zettel that a cocktail formula must be tuned to the actual whiskey. This extends provenance without creating a duplicate Zettel.
Practitioner guidance within Sandham’s Manhattan discussion. The named bourbon is an example from 2012, not a universal brand prescription; the durable point is that whiskey choice and modifier ratio interact.
Sandham treats bourbon-versus-rye selection as a balance decision in a Manhattan: a sweeter bourbon supports a sweeter result, while rye supports a drier one, and he explicitly invites adjustment of vermouth rather than treating one ratio as universal.
