Here’s a fun drink that’s easy to whip up and packs a massive flavor punch: the Skeleton Key cocktail! This combination of bourbon, elderflower, and ginger beer is a unique highball drink that’s bubbly, floral, and bittersweet!

Topping it off with bitters creates a floating orange haze. It’s a modern classic invented in Detroit with a spooky origin story, but I think it works any time of the year. Here’s how to make this easy cocktail.

What’s in a Skeleton Key Cocktail?

The Skeleton Key cocktail is a highball made with bourbon, elderflower liqueur, lemon juice, and ginger beer. It’s topped with bitters that form an eerie orange haze floating on the surface.

The Skeleton Key was invented in 2011 at the now-closed Detroit restaurant Roast. Then, bartender Brian Volmer created a cocktail for a local Halloween competition, which went on to become popular at bars around Detroit.

The drink’s name is inspired by its rusty color, which made Vollmer think of the skeleton keys that opened the locks in his grandparents’ house. This highball cocktail is a beautiful balance between bourbon, floral elderflower liqueur, and spicy ginger beer. While it’s the perfect Halloween cocktail, I think it’s more fun any time of the year!

The ingredients for a Skeleton Key cocktail are:

  • Bourbon
  • St. Germain elderflower liqueur
  • Lemon juice
  • Ginger beer
  • Angostura bitters

Tips for Making the Drink

Want to whip up a Skeleton key cocktail? Here are a few quick notes on this drink:

  • It can be built in the glass! Any time I can get away without dirtying a cocktail shaker, I do it! This one is perfect for entertaining.
  • Add the ginger beer right before serving. To preserve the bubbles, don’t mix in the ginger beer until right before serving.
  • Generously shake in the bitters (and if desired, stir!). The fun part of this drink is the haze of bitters that hangs at the top. However, it tastes best when the bitters are integrated into the drink, so you may want to stir before drinking.

More About St Germain

This drink requires a bottle of St Germain elderflower liqueur, but it’s absolutely worth a purchase! This tasty liqueur is a favorite of mine that you can use to make a French Gimlet, Hugo, and these 10 Best St Germain Cocktail recipes.

  • St Germain is a liqueur that’s made with elderflowers, the small white flowers of an elderberry plant. The flavor is light, sweetly floral, and fragrant. To pronounce it, say “Sahn-jer-MAHN”.
  • Fun fact: it’s relatively new to the scene. St Germain was invented in 2007! The vintage-looking bottle makes it seem like it has hundreds of years of history, but a guy named Rob invented it in 2007. (Here’s the story behind it.)
  • How much does it cost? That beautiful bottle will set you back about $20 to $30.

Best Ginger Beer

There are lots of ginger ale brands on the market, but not all are created equal! I have a few favorites when it comes to ginger beer:

  • Q Ginger Beer: This is my top choice! It comes in small cans, so you only have to use a little at a time.
  • Fever Tree Ginger Beer: Fever Tree is made with real ginger and has no artificial sweeteners.
