Prepare the blackberry syrup (if homemade): In a small saucepan, combine blackberries, sugar, water, and lemon juice. Bring to a simmer over medium heat, stirring occasionally for 10-15 minutes until berries break down. Strain through a fine mesh sieve, pressing to extract juice. Cool completely before use. (Makes about 8 oz; store extras in the fridge.)

Chill your glass: Place a highball or rocks glass in the freezer for 5 minutes or fill with ice to cool it down – this keeps your drink icy cold.

Add ice: Fill the glass halfway with ice cubes for that refreshing chill.

Pour the vodka: Measure and add 1 oz of lemon vodka over the ice.

Add blackberry syrup: Pour in 1.5 oz of blackberry syrup for that signature sweet-tart flavor.

Top with soda: Slowly add 3-4 oz of chilled soda water or Sprite Zero, leaving room at the top to prevent overflow.

Stir gently: Use a bar spoon or long stirrer to mix lightly – don't over-stir to preserve the bubbles.

Garnish and serve: Squeeze a lemon wedge over the top, then drop it in. Add blackberries or mint for extra flair. Enjoy immediately!
