Prep Glass: Fill your Collins glass with ice cubes. Give it a stir to chill it and set it aside.
Add Simple Syrup: Pour ¾ oz simple syrup into the shaker.
Add Lemon Juice: Add 1 oz lemon juice.
Add Brandy: Pour 2 oz Brandy into the shaker as well.
Shake: Fill the shaker with ice, close it and give it a good shake (10-15 seconds).
Strain: Take the Collins glass, discard the ice inside and refill with new, fresh ice cubes. Then, use the cocktail strainer to strain the shaken drink into the ice filled glass.
Top with Soda: Top off with 3-4 oz club soda (adjusting to taste and to the size of the glass).
Stir: Using a bar spoon or long stirrer, stir gently to combine.
Garnish: Garnish with a lemon slice and mint sprigs. Sprinkle with icing sugar and serve immediately.
