Classic Mojito Cocktail (IBA Spec – Rum, Mint & Lime Highball)

Bright, minty, and sharply refreshing, the Mojito is one of the most recognizable highballs in the world. Built on rum, lime, and fresh herbs, it’s a drink that feels effortless but relies on balance and technique to get right.

Background

The Mojito traces back to Cuba, with roots often linked to 16th-century medicinal drinks made with sugarcane spirits, lime, and mint. It became globally popular in the late 20th century as a warm-weather staple, known for its clean, refreshing profile and simple build.

What You’ll Need

Ingredients

• Light Rum – the clean, slightly sweet base that carries the drink
• Lime Juice – fresh acidity that defines the structure
• Simple Syrup – balances the lime with smooth sweetness
• Mint Leaves – adds aroma and cooling herbal notes
• Soda Water – lengthens the drink and adds effervescence

Substitution ideas:

• No simple syrup? Use 2 tsp fine sugar and dissolve well
• No lime? Lemon works, but changes the classic profile

Equipment

• Highball glass
• Muddler
• Bar spoon

Why This Version Works

Built to IBA Balance

This Mojito follows the official IBA ratio, keeping the drink crisp and not overly sweet. The balance of rum, lime, and sugar is tight, letting the mint and soda stay bright instead of getting lost.

Substitutions & Variations

• Fruit Mojito: Add muddled strawberries, mango, or pineapple
• Herbal twist: Swap mint for basil for a different aromatic profile
• Rum variation: Try lightly aged rum for added depth
• Stronger build: Increase rum slightly for a bolder version

Helpful Tips

• Muddle mint gently — crushing it releases bitterness
• Use fresh lime juice only — bottled will flatten the drink
• Add soda last to preserve carbonation
• Clap the mint garnish before serving to release aroma
