 St. Germain Gin and Tonic Cocktail

Are you familiar with St. Germain? Made with fresh, hand-picked elderflower blossoms, it’s an artisan French liqueur sold in a stunning art deco bottle. A few years ago, I stocked my liquor cabinet with this versatile spirit to make some festive Pear Cosmopolitans for my book club.  This Elderflower Sangria also caught my attention. 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!

Tips for Making a St. Germain Gin and Tonic

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.

  • I made this St. Germain Gin and Tonic 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. Cheap gin doesn’t belong in this cocktail!

  1. Your French drink does sound like the perfect way to make a party festival. Love the idea that the brew is made of elderflowers. P.s. I believe St. Germaine was also a teacher who could allegedly turn metal into diamonds…or something like that!

  2. Very refreshing.. a perfect summer cocktail, Liz.

  3. Going to have to try this one! Love the elderflower! Yum!

  16. So pretty. I will check our LCBO if they have this extraordinary spirit.

  17. Fabulous pick, dear! xoxo

  18. I absolutely LOVE this idea. So simple and refreshing and it’s a great way to cut through the insipid sweetness of St. Germaine with the bitter bite of quinine. GREG

  19. I am glad Elderberry liquor is available here in the US , it’s such a tasty drink. I will make your pear cosmopolitan for my next book club meeting.

  20. This French cocktail sounds so wonderful and festive. This would be perfect for a summer treat.

  21. I never tried St. Germain. This drink will remedy that!

  22. I love how cool and refreshing this looks! I am looking forward to making your recipe. I haven’t used Elderflower liqueur yet, and I am very intrigued!

  23. I’m a big fan of G&Ts and I love this variation.

  24. The G&T has become one of my go-to drinks. Definitely trying your version soon – I have a bottle of St Germain that I’ve been experimenting with, but have yet to find a recipe that I love with it. I’m betting this will be it. 🙂

  29. I love this Liz and will definitely try it this week. I’d love to know where you saw the recipe for the Elderflower Sangria. I’d love to make that too!

  30. Love this recipe. I like to muddle a little fresh mint in the glass and add a splash of grapefruit juice. Sometimes substitute with a nice vodka…all else remains as in your recipe.  My only problem is I love elderflower liquor a bit too much so I’ve started used Drilaud Elderfower liquor to save money.  It’ts really delicious.  

  31. I love to make these when I have cocktail parties!

  32. I loved it! Taste really good and refreshing!

  33. St. Germain drinks never disappoint and this one is no exception. So easy to make yet SOOOO good.
