Why You Must Make

  • The simple addition of St. Germain liqueur transforms a run-of-the-mill gin and tonic into a memorable cocktail. Made with fresh, hand-picked elderflower blossoms, it’s an artisan French liqueur sold in a stunning art deco bottle.
  • It received rave reviews when I served these to my book club. I had to show them all my bottle of St. Germain!
  • It’s the perfect summer cocktail, but delicious to sip on all year long.

Expert Tips

If you like the classic gin and tonic, try this twist and you may never go back!! Here are a few tips for making this easy cocktail.

  • PRO-Tip: I made this cocktail with a 1:2 ratio of gin to tonic. If you prefer, you can use a 1:1 ratio.
  • I like my gin and tonics with lime, but you can also use lemon or even orange in place of the lime.
  • Serve this cocktail “on the rocks,” meaning fill the glass with ice, then pour over the gin, St. Germain, and tonic water. A squeeze of lime is added before the ice.
  • Use your favorite gin. I used Bombay Sapphire as it was one of my dad’s favorites. Inexpensive gin doesn’t belong in this cocktail!

Frequently Asked Questions

What is St. Germain?

St. Germain is a French-made 40-proof liqueur made from elderberry blossoms, small, white star-shaped flowers that are harvested only 3 weeks of the year. More popular in Europe, St. Germain has gained fans in the US over the past few years. Sweet and floral, it’s a lovely compliment to both the gin and lime in a gin and tonic. Plus it turns a commonplace cocktail into something extraordinary!

Should You Refrigerate St. Germain?

Since it’s 40-proof and considered hard alcohol, there’s no need to keep an opened bottle in the refrigerator. I like keeping it chilled for a party to ensure the mixed cocktails are nice and cold!

How Do You Make an Elderflower Gin and Tonic?

Just add the St. Germain to your glass along with the gin. To differentiate it from an ordinary Gin and Tonic, try serving it with a sprig of fresh basil.
