- Substitute black walnut, cinnamon, nutmeg, or cardamom bitters for the ginger bitters.
- Replace the splash of water with a splash of ginger beer or ginger ale.

About the Rum Old-Fashioned
With its funky molasses taste, dark rum is the perfect spirit for an old-fashioned. It's barrel-aged, giving dark rum the warm, toasty flavors familiar in other brown liqueurs, but it also brings its own complexity and sweetness to create a nuanced, warming rum-lover's drink. So whether you choose a Demerara rum from Guyana, a rhum agricole from the French Caribbean, a barrel-aged cachaça from Brazil, or a flavorful spiced rum, it's easy to create a spicy, tasty cocktail that will please your palate.
Baby We Were Born to Rum
One of the simplest ways to put your own spin on a cocktail is to switch the spirit. And in the case of the rum old-fashioned, replacing the traditional whiskey with dark or spiced rum is bound to be a rum-away success.
