Modern American Drinks by George J. Kappeler (1895, p.38) — George J. Kappeler 1895
| 0.5 jigger | Irish whiskey — whiskey | base |
| 3 dash | orange bitters — orange bitters | bitter |
| 0.5 jigger | sweet vermouth — Italian vermouth | modifier |
| 2 dash | Acid phosphate — acid phosphate | other |
- Fill a mixing-glass half-full with fine ice.
- Add the orange bitters, acid phosphate, Irish whiskey, and Italian vermouth.
- Mix well, strain into a cocktail glass, and serve.
- Nose
- Vermouth herbs and whiskey appear first, but the acid phosphate promises a brighter, more tensile palate.
- Palate
- This is an unusually sharp take on the vermouth-and-whiskey formula, with acid phosphate giving lift without moving the drink fully into sour territory.
- Finish
- The finish is drier, brisker, and more mineral than a standard sweet Manhattan type.
- Summary
- A brightened Irish-whiskey aromatic cocktail that sits between Manhattan logic and acidulated modernity.
This is a particularly interesting Kappeler entry because acid phosphate introduces a late-century functional ingredient that points toward newer ways of tightening and refreshing cocktails without citrus juice.
Acid phosphate is the defining feature. It changes the drink's line without changing its core spirit-and-vermouth skeleton.
