Take your glass and gin and place it in the freezer 30 minutes to an hour before making your cocktail. This is optional but will yield best results.
Fill an 8oz glass all the way with ice. I prefer a highball or rocks glass.
Pour over 1 shot of gin and ½ shot of elderflower liqueur. Fill the rest of the glass with tonic water. If desired, but optionally, garnish with a sliced halved cucumber and a lime wedge.
If you want to serve your gin and tonic in a large "sangria" style fashion for a party, use a ratio of 1:2:8 Elderflower:Gin:Tonic - so if you're making a very large batch, you could use 1 cup or Elderflower Liqueur, 2 cups of Gin and 8 cups of Tonic Water.
For this, you can put a few cups of ice in the mixture, but it's best to place fresh ice in a glass and top with the drink mixture as needed.
For brand recommendations, I've gone into full detail in the post for both tonic water and gin. For elderflower liqueur, I only use St. Germain.
