Tonic Bar @ Opower + the Elderberry Lavender Tequila & Tonic Cocktail Recipe

Tonic Bar @ Opower + the Elderberry Lavender Tequila & Tonic

We loved getting to be part of a staff party at Opower. You could tell instantly that the company was cool and the people were great and made us wonder if we could ever have a career in energy efficiency. The answer to that is, probably no, but we’ll settle for serving drinks to these fine folks.


Our tonic bar is perfect for parties with a range of drinkers. The gin & tonic is, of course, the unassailable king of the ‘& Tonic’ world. But other spirits go well with tonic too. And you can add just a splash of a liqueur to bring some other flavors into the mix too.

Tonic drinks are easy to design, easy to mix, and easy to match with most anyone’s drink tastes. There are enough options that people can have fun experimenting, but enough familiarity that it’s not overwhelming.

Here was the line-up for this Tonic Bar

Choose a Base Spirit

  • District Made Vodka (from One Eight)
  • Tequila (our favorite is El Jimador)
  • Ivy City Gin (also a One Eight product)
  • Vermouth

Add a Splash?

  • St. Germain
  • Canton Ginger liqueur
  • Elderberry lavender syrup (from our friends at Wild Roots)
  • Lemon cardamom syrup (also from Wild Roots)

Garnish or muddle?

  • lemon
  • lime
  • blackberry
  • mint

Top with

  • Tonic
  • Ginger beer

The most popular order was still the classic G&T, but a strong number two was gin, tonic, and a splash of St. Germain, which bodes well for our hope that St. Germain takes the place of the vanilla vodka that all bars insist on stocking.  We especially loved the guests who progressively became more creative as the party went on.  Gin, ginger, and ginger beer! Muddled lime, tequila, and tonic! Surprise me! It’s exactly the type of creativity and interaction we love and just another reason why we think the tonic bar is awesome.    

Our favorite tonic creation of the night was this guy:

Elderberry Lavender Tequila & Tonic


  • 2 oz Tequila
  • .25 oz Elderberry Lavender syrup
  • 2 oz Tonic
  • Blackberry (for garnish)
  • Mint sprig (for garnish)


  • Pour elderberry lavender syrup and tequila into old-fashioned glass
  • Stir until syrup is well dissolved
  • Add ice
  • Top with tonic
  • Garnish with blackberry and mint
