A nineteenth-century whiskey cocktail enhanced with maraschino, absinthe, and dual bitters.
The Improved Whiskey Cocktail starts from spirit, sugar, and bitters, then adds maraschino and absinthe for aromatic lift. Rye provides spice and dryness, the bitters deepen the finish, and the liqueur additions perfume the drink without turning it into a multi-liqueur showpiece. Stirred and served up or on a large cube, it sits between a plain whiskey cocktail and later Old Fashioned elaborations. Jerry Thomas published an early improved-style template in the 1860s.

“Jerry Thomas’s How to Mix Drinks (1862) popularized “improved” cocktails that add liqueurs and absinthe to the basic spirit-sugar-bitters formula.”
Treat absinthe as seasoning—rinse or a scant quarter-ounce is enough. Dual bitters matter; Peychaud’s softens Angostura’s spice.
