Penguino – Rum, Triple Sec & Tonic Highball

The Penguino keeps things simple: rum provides the base, triple sec adds orange flavor and sweetness, and tonic water stretches everything into a bubbly highball. The tonic's bitterness keeps the orange liqueur from feeling too sweet, making this an easy option when you want a long rum drink without juice, syrup, or shaking.

A Simple Rum Highball

The current recipe record does not establish a documented creator, location, or period of origin for the Penguino. Its structure follows the familiar highball approach of combining a base spirit with a longer carbonated mixer, with triple sec adding a distinct orange accent between the rum and tonic.

What You'll Need

Ingredients

• Rum – forms the spirit base and supplies the drink's core character.
• Triple Sec – adds orange flavor and a measured amount of sweetness.
• Tonic Water – lengthens the drink with carbonation and quinine bitterness.

Substitution ideas:

• No triple sec? Cointreau or orange curaçao can provide a similar orange-liqueur role.
• Want more depth? Use an aged rum in place of a lighter rum.
• Prefer less bitterness? Club soda can replace tonic water, though the drink will taste noticeably softer and less complex.

Equipment

• Collins glass
• Jigger
• Bar spoon
• Ice

Orange Meets Tonic Bitterness

What makes the Penguino work is the contrast between sweet orange liqueur and bitter tonic. Rum sits underneath both, giving the drink more character than a simple spirit-and-tonic combination. Because the recipe is built long over ice, the flavors remain light enough for casual sipping.

Substitutions & Variations

• Use light rum for the cleanest, brightest version.
• Try aged rum for vanilla, oak, and richer sugarcane notes.
• Replace triple sec with Cointreau for a drier, more concentrated orange profile.
• Use orange curaçao for a slightly richer citrus variation.
• Swap tonic water for club soda when you want less bitterness.
• Add a small squeeze of fresh lime for extra acidity, if you are intentionally making a variation rather than the original recipe.

Helpful Tips

• Chill the tonic water before mixing so the finished drink stays colder and retains more carbonation.
• Fill the Collins glass generously with ice to slow dilution.
• Pour the tonic last.
• Stir only briefly after adding tonic water so you do not knock out unnecessary carbonation.
• Serve immediately while the drink is cold and lively.
• Pair it with salty snacks, grilled seafood, or light appetizers that complement the orange and tonic notes.
