Fill a lowball glass with ice. Add all ingredients to glass and gently stir to combine. Garnish with lemon wedge, if desired.
You can use either a highball or lowball glass with this recipe. I prefer a lowball glass because I think it makes for a well balanced drink but you can do a highball if you prefer. Whatever glass you use, make sure you fill the entire thing with ice to ensure your drink stays well chilled the whole time you are drinking it.
Good ingredients are crucial to a good tasting cocktail. That means using a quality vodka and elderflower liqueur and freshly squeezed citrus juice. (We're big fans of Drillaud Elderflower Liqueur.)
Feel free to swap in lime juice instead of lemon juice if that's what you prefer.
The individual small cans of club soda are great for single drinks like this vodka soda.
