What is a Cadillac Margarita with Cointreau?

Few cocktails signal luxury the way a Cadillac Margarita does. Built for those who want a smoother, richer take on the classic Margarita, this drink replaces ordinary triple sec with Cointreau and floats premium Grand Marnier on top—adding depth, complexity, and unmistakable citrus character.

How the Cadillac Margarita Differs from the Classic

The Cadillac Margarita elevates the traditional Margarita in two main ways:

It uses Cointreau instead of generic triple sec, delivering a purer, more refined orange flavor.
It features a float of Grand Marnier, a Cognac-based orange liqueur, which adds aromatics and a velvety finish.
The tequila choice is usually top-shelf (reposado or añejo), adding oak, vanilla, or spice notes.

In classic Margaritas, triple sec and blanco tequila are standard. Triple sec tends to be sharper and less rounded than Cointreau. The Cadillac approach leans on well-balanced citrus and oak, creating a smoother, more luxurious experience.

22.5 ml Cointreau
30 ml fresh lime juice

How to Make a Cadillac Margarita

Run a lime wedge around half the glass rim. Dip in salt if desired.
Fill a shaker with ice. Add 60 ml tequila, 22.5 ml Cointreau, 30 ml lime juice, and 7.5 ml agave syrup if using.
Shake hard for 10–15 seconds.
Strain into an ice-filled double old fashioned glass.
Slowly float 15 ml Grand Marnier on the surface by pouring over the back of a spoon.

Premium Tips: Get the Most from Your Cadillac Margarita

Choose a reposado tequila for subtle vanilla and oak notes, or try añejo for deeper character.
Always use freshly squeezed lime juice; bottled lime lacks the aroma and bracing acidity needed to stand up to the liqueurs.
If you like it less sweet, skip the agave syrup—the orange liqueurs already bring natural sweetness.
For a lighter nose, serve without a salt rim; for an old-school kick, salt just half the glass.
Chill your glass before serving: 5 minutes in the freezer makes the pour extra smooth.
