At Rumba, a rum-focused bar in Seattle, this drink, a twist on the Cuba Libre, was originally pre-bottled. “We had custom bottle openers made with our logo on it,” recalls general manager Jen Akin. “It was served as a kit with a block of ice, lime [to squeeze or garnish] and you got to keep the bottle opener. It was cute.” Yet, it was challenging to keep the bubbles for longer than a few days; the drink is now served on tap instead. The below is a home-friendly version of the cocktail.

Editor's Note
Rumba’s cola syrup recipe follows, but as an alternative, Akin also suggests Bigallet Cola Syrup, which can be purchased on Amazon. When mixing the drink, add a squeeze of lime juice to add the tartness that citric acid would otherwise supply.
Cola Syrup:
zest of two oranges
zest of 1 lemon
zest of 1 lime
6 3-inch cinnamon sticks, crushed
2 tablespoons dried bitter orange peel
2 teaspoons whole coriander seed
1/4 teaspoon grated nutmeg
1/2 teaspoon dried lavender
1 star anise pod
2 tablespoons ginger, minced
1 whole vanilla bean, split and scraped
1/4 teaspoon citric acid powder
4 cups water
4 cups white sugar
In a saucepan, combine all ingredients except sugar. Bring to a boil and simmer, covered, for 20 minutes. Remove from heat. Add sugar, and stir until dissolved. Strain, and let cool. Bottle and refrigerate for up to two weeks.
