The fine-tuned mix of sweet, spicy, and citrus makes the rum fever a divine cocktail for any occasion. It comes from the mind of U.K. bartender Joseph Cassidy and is an absolute delight, offering a unique flavor experience that makes exploring cocktails so much fun.
The beauty of this drink is its ability to combine those three aspects of flavor into a tantalizing mix. The spice (and a little sweetness) comes from a homemade chipotle syrup that takes less than an hour to make. That is backed up by an intriguing chocolate spirit which is not sweet like the typical chocolate liqueur. Instead, Mozart Chocolate Spirit has a dry, bittersweet profile—likened to chocolate vodka—with no sweetener added, which is why it's a "spirit" and not a "liqueur." It can easily become a new favorite in your bar.
Behind all of that is a very nice rum from Flor de Caña. The brand makes two 4-year-old expressions, both of which are surprisingly dry as well. Whether you choose the Extra Seco or the Oro rum, it's sure to be a brilliant background for this fascinating cocktail.
- For the Spiced Chipotle Syrup:
- 1 cup water
- 2 chile peppers (chipotle; dried)
- 1 cup white sugar
- Pinch sea salt
- 3 dashes Angostura Bitters
- For the Cocktail:

- 3/4 ounce chocolate liqueur (Mozart Dry Chocolate Spirit)
- 1 ounce lime juice (fresh)
- 3/4 ounce spiced chipotle syrup
Note: while there are multiple steps to this recipe, this cocktail is broken down into workable categories to help you better plan for preparation and assembly.
Make the Spiced Chipotle Syrup
Gather the ingredients.
In a small saucepan, gently boil the water.
Slice the chilies and remove most of the seeds (the more you leave, the hotter the syrup will be).
Take the water off the heat and soak the chilies in it for 12 minutes.
Remove and discard the chilies, then fine strain the water into another saucepan.
Add the sugar and salt. Heat gently while stirring until both are dissolved.
Add the bitters, stir and then remove from the heat.
Allow it to cool before bottling. Store in the refrigerator for up to one week.
Make the Cocktail
In a cocktail shaker filled with ice, pour the rum, chocolate spirit, lime juice, and chipotle syrup.
Serve and enjoy!
How Strong Is a Rum Fever?
Both the rum and chocolate spirit are bottled at 80 proof. They combine to create a full-flavored cocktail that's a little on the strong side. You can expect this one to have an alcohol content around 19 percent ABV (36 proof), which is typical for this style of cocktail.
