What Is Jamaican Iced Coffee with Brown Rum?

This isn’t your standard iced latte or espresso tonic. It’s a Caribbean-inspired coffee cocktail that blends strong brewed coffee, a measure of potent Jamaican brown rum, a splash of lemon-lime soda, and ice. The result is a sweet, boozy, effervescent drink often served as a digestive or post-dinner treat. It carries the boldness of dark rum and the bitterness of coffee, smoothed out by carbonation and finished with a salty snack.

Why Use Jamaican Brown Rum?

Jamaican brown rum is known for its full-bodied, molasses-heavy profile and deep flavor. Unlike lighter rums, it has a weighty mouthfeel and a warming finish—qualities that stand up to the bitterness of coffee and the acidity of soda. The article specifically calls for a high-quality Jamaican brown rum to get the best results, emphasizing that the spirit’s character is central to the drink’s appeal.

Frequently Asked Questions

What kind of coffee should I use for Jamaican iced coffee?

The original recipe doesn’t specify the coffee type, but it assumes a pre-sweetened iced coffee. For best results, use a strong, medium to dark roasted coffee brewed strong and chilled. A classic espresso blend or dark roasted single origin would work well if you’re brewing it yourself.

Can I use a different rum?

The recipe insists on using Jamaican brown rum for the best flavor. It describes the drink as being defined by the rum’s “，”—rich, bold flavor with a strong kick. Substituting with a lighter or non-Jamaican rum will change the taste profile significantly.

Is 7-UP the only soda you can use?

Yes, the recipe specifically calls for 7-UP. Its lemon-lime flavor and carbonation are integral to the drink’s balance. Using a different soda will alter both taste and texture. If 7-UP isn’t available, a similar lemon-lime soda could be considered, but it won’t be authentic.

Do I need to use peanuts?

The recipe includes a small plate of peanuts as an accompaniment. While not essential to the drink itself, peanuts offer a salty contrast that pairs well with the sweet and boozy flavors, making it a more complete dessert-like experience.

Can I make this drink ahead of time?

No, this drink is best assembled immediately before serving. The carbonation in the 7-UP will dissipate, and the ice will dilute the coffee and rum over time, weakening the flavor balance. Prepare it fresh for the intended effect.
