Tequila Cooler - Tequila, Lime & Lemon-Lime Soda Highball

The Tequila Cooler combines tequila blanco with lemon-lime soda and a small amount of lime juice in a tall glass over ice. Tequila provides the agave backbone, the soda adds sweetness and bubbles, and lime sharpens the finish. It is a straightforward mixed drink where cold ingredients and gentle handling of the carbonation matter more than elaborate technique.

What You'll Need

Ingredients

• Tequila blanco - provides the crisp agave base.
• Lemon-lime soda - adds citrus sweetness, length, and carbonation.
• Lime juice - gives the drink an optional extra edge of fresh acidity.

Reposado tequila can replace blanco for more oak, vanilla, and cooked-agave flavor. Club soda with fresh citrus can make a drier variation, but it will need sweetness adjusted to taste.

Equipment

• Highball glass
• Jigger
• Bar spoon
• Ice

A Highball That Keeps the Agave Visible

Six ounces of soda make this a long drink, but the two-ounce tequila pour gives it enough structure to remain recognizable. The optional lime is useful when the soda tastes especially sweet, adding just enough acidity to tighten the finish without turning the drink into a Margarita.

Substitutions & Variations

• Use reposado tequila for a rounder, oak-influenced cooler.
• Replace part of the lemon-lime soda with club soda for less sweetness.
• Add a small splash of grapefruit soda for a Paloma-adjacent variation.
• Use fresh lemon instead of lime for a softer citrus edge.
• Garnish with lime, lemon, or a thin cucumber ribbon.

Helpful Tips

• Chill the soda before building the drink.
• Fill the highball glass generously with fresh ice.
• Add the soda last to preserve carbonation.
• Stir only once or twice after topping.
• Taste before adding the optional lime because soda brands vary in sweetness and acidity.
• For several servings, measure tequila into glasses ahead, then add soda individually just before serving.
