The Rum Old Fashioned is like a classic Old Fashioned with one exception – it’s crafted with rum instead of whiskey. After you follow our easy recipe and craft this drink at home, you’ll wonder where this stiff rum cocktail has been all of your life.
While sipping a Rum Old Fashioned at a bar, we had one of those aha moments. Why does the primary ingredient in an Old Fashioned have to be whiskey?
The answer – it doesn’t.
We were so inspired by this revelation that we crafted Rum Old Fashioned cocktails at home a few days later. We even bought the same Riedel rocks glasses designed by Zane Harris to replicate the bar experience. Yes, we’re that obsessed.
Replacing whiskey with rum seems so simple. And, yet, a Rum Old Fashioned is its own special cocktail. Since it’s super easy to craft and dangerously delightful to sip, it’s now become part of our home cocktail rotation.
What Is A Rum Old Fashioned Cocktail?
The Rum Old Fashion is a modern twist on one of the world’s most classic cocktails. And, no, we’re not talking about the orange twist that often garnishes both versions.
While replacing bourbon with rum is the obvious twist, we go one step further in our Rum Old Fashioned recipe by replacing Angostura bitters with orange bitters. The resulting cocktail has a tropical flavor that screams summer but tastes great all year long.
History Of The Old Fashioned Cocktail
While we don’t know when or where the Rum Old Fashioned was invented, we do know that the original Old Fashioned pre-dates Prohibition. It was possibly invented in Louisville during the Civil War but its origin may go back further. It’s so iconic that people drink Old Fashioned cocktails in old fashioned glasses.

You may have all of these ingredients in your pantry and liquor cabinet. If not, they should be easy to find at your local market and/or liquor store.
Use your favorite aged or dark rum in this recipe. We like to use Havana Club Ańejo Especial Cuban Rum We bought our first bottle of this aged rum to craft Cuba Libre cocktails. Double aged in oak barrels and with flavors that include cinnamon, orange and vanilla, the golden Cuban rum is now our go-to aged rum for crafting rum cocktails. It has a 40% ABV.

We bought a bottle of Angostura orange bitters specifically to craft Bijou cocktails and we’re still using that same bottle. With an aromatic blend of orange extracts and spices, these orange bitters smell delightful. They also add provide a pleasant kick thanks to a 28% ABV.
How To Craft A Rum Old Fashioned
The first step in this recipe is to drop a sugar cube into an old fashioned glass.
Add a few dashes of orange bitters and a splash of water to the glass.
Muddle the sugar cube, bitters and water with a muddler. Ideally, you can use the bottom, muddling end of your bar spoon to do the muddling.
Drop a jumbo ice cube tray into the glass. The bigger the better! Not only do jumbo ice cubes look pro, but they also melt more slowly due to their size.
Measure the aged rum with a jigger and pour it directly into the glass. We always use a Japanese jigger when we measure liquor to achieve accurate measures and clean pours.
Give the cocktail a good stir using a bar spoon or other stirring implement.
Express an orange peel around the glass’s rim. This step releases pleasing orange scents and coats the rim with a light layer of orange oil.
Drop the orange peel into the glass.
Feel free to add a maraschino cherry or two as additional garnish. We recommend using Luxardo cherries if you go this route since they’re simply the best.
