Rattler Tequila Highball – Grapefruit, Lime & Triple Sec Collins

A bright, citrus-forward tequila highball, the Rattler combines grapefruit, lime, and orange liqueur for a clean, refreshing drink that’s easy to build and even easier to enjoy. It’s a natural fit for summer afternoons, casual gatherings, or anytime you want something light with real flavor.

Background

The Rattler isn’t a classic with a fixed origin, but it clearly draws inspiration from tequila highballs like the Paloma. As grapefruit-based cocktails grew in popularity, variations like this emerged, leaning on simple builds and fresh citrus to create approachable, crowd-friendly drinks.

Citrus Without the Weight
This drink keeps things light while still delivering layered citrus flavor. Grapefruit leads, lime tightens the structure, and triple sec smooths the edges, all lifted by soda for an easy, refreshing finish.

Substitutions & Variations

• Swap tequila for mezcal for a light smoky edge
• Use ruby red grapefruit juice for a slightly sweeter profile
• Add a pinch of salt to push it closer to a Paloma style
• Turn it into a spritz with a splash of sparkling wine

Helpful Tips

• Use fresh lime juice for a cleaner, sharper taste
• Chill your glass beforehand to keep the drink crisp longer
• Don’t over-stir after adding soda to preserve carbonation
• Garnish with a grapefruit wedge or lime wheel for extra aroma
