Root Beer Float Martini


The Classic Root Beer Float Martini Recipe




  1. Chill Your Glass: Begin by chilling your martini glass in the freezer for about 10 minutes. A cold glass will keep your drink delightfully frosty.
  2. Mix: In a shaker, combine one part vanilla vodka with one part root beer.
  3. Shake: Add ice to the shaker and shake well until the mixture is chilled.
  4. Serve: Strain the mixture into your chilled martini glass. The frothy top will remind you of the classic root beer float.


This cocktail offers an easy and delicious way to whip up a simple martini that mirrors the taste of a classic root beer float.

We may be a little biased, but we think the best root beer to use is Root 42.

Why, you ask?

We caramelize our pure cane sugar for every batch, and don't skimp on using real vanilla. With its heavy body and deep root beer flavor, it's the perfect soda to balance against the vodka. Whatever you do, never settle for any generic root beers that use high-fructose corn syrup!

Is root beer and vodka a good combo?

Absolutely! Vodka goes well with almost anything, and root beer is no exception. Flavored vodkas are even better. This recipe uses vanilla vodka, but marshmallow vodka is equally delicious.




Variations to Spice Up Your Root Beer Float Martini

For those who love a creamier texture, add a splash of heavy cream or half-and-half to the shaker before mixing. This variation enhances the "float" aspect of the cocktail, making it even more reminiscent of the classic root beer float.

  1. Spice It Up: Add a cinnamon stick or a dash of nutmeg to the shaker for a spicy twist. The warm spices complement the vanilla and root beer flavors beautifully, adding depth and warmth to your cocktail.
  2. Root Beer and Vodka Float: For a literal take on the "float," add a small scoop of vanilla ice cream to your martini after pouring. The ice cream slowly melts into the drink, creating a decadent, ever-evolving taste experience.
  3. Boozy Cherry Top: Garnish your martini with a maraschino cherry or a splash of cherry syrup for a fruity note that contrasts with the creamy vanilla and vodka.
  4. Whipped Cream and Chocolate Drizzle: Hit the mix with these classic float toppings to really seal the deal.
