Rum and Soda

Overview

What this drink is like

The first sip is clean and slightly sweet from the rum, with a crisp carbonation carrying it across the palate. It finishes dry and light, leaving just a hint of sugarcane or molasses behind depending on the rum you chose.

Who will like it

For people who like straightforward, spirit-forward but low-proof drinks that go down easy.

When to drink

This is a hot afternoon or lazy beach day drink when you want something cold but don't want to think too hard about it.

Ordering tip

Specify your rum preference—white for clean and crisp, dark for richer molasses notes—or you'll likely get whatever the house well is.

Flavor

Taste profile

This is a straightforward, no-nonsense thirst quencher. You get the gentle sweetness of the rum up front, followed by the dry, scrubbing bubbles of the soda. It's not a drink that unfolds in layers; it's a drink that gets the job done when it's hot out and you want something cold with a kick.

Finish: The finish is short and dry, leaving a faint echo of sugarcane or molasses on the breath.

Steps

  1. 1

    Fill a highball glass to the top with ice cubes. Cold ice and a cold glass keep the soda from going flat too fast.

    !Using warm glassware makes the ice melt quickly and waters down the drink.

  2. 2

    Pour 50ml of rum over the ice. Let it settle to the bottom of the glass.

    !Pouring too fast can splash, but otherwise just get it in the glass.

  3. 3

    Top with 100ml of cold club soda, pouring it gently down the side of the glass to keep as much fizz as possible. You want to preserve the bubbles so the drink stays crisp to the last sip.

    !Dumping the soda straight down the middle kills the carbonation.

  4. 4

    Take a bar spoon and give it one or two gentle lifts from the bottom to mix the rum and soda without stirring out the bubbles. You'll know it's mixed when the liquid looks uniform.

    !Stirring vigorously makes the drink flat.

  5. 5

    Place a lime wedge on the rim of the glass or drop it in. Give it a squeeze over the drink first if you want a little bit of acidity to cut the sweetness.

    !Forgetting to squeeze the lime if you want that bright note, leaving the drink tasting a bit flat.

Serve

Serve it right away while it's still bubbling and cold. A straw is optional but nice for sipping.

History

Origin

The Rum and Soda is a basic highball that emerged naturally wherever rum was produced and carbonated water was available, likely in the late 19th or early 20th century. It doesn't have a single inventor or a specific creation story, existing simply as the natural pairing of a local spirit with the era's popular new mixer.

Tips & pitfalls

Tips

Worth knowing before you pour

  • Use a good quality rum since it's the main flavor.
  • Keep your soda in the fridge so it stays fizzy longer.
  • Squeeze the lime wedge into the drink for a much better balance.

Avoid

Common mistakes

  • Using cheap, harsh rum since there's nothing to hide it.
  • Stirring too hard and making the drink flat.
  • Using warm soda because it will fizz over and taste watered down.
