To make the simple syrup add water and sugar to a medium saucepan. Bring to a boil and simmer until sugar dissolves. Take about 2 minutes. Take off the heat and allow to cool completely. (Place in the freezer and in a different container to cool quicker)

Add cooled simple syrup, lemon juice, vodka, triple sec, strawberries, blueberries and mint to a large pitcher. Stir to combine.

Pour into glasses. Top each glass with 1 ounce of sparkling water per glass. This is optional but gives the lemonade a nice fizz. Add the sparkling water to the glass not the pitcher to ensure the drink does not go flat. Enjoy!
