Combine the organic turbinado sugar and filtered water in a small saucepan on medium-low heat. Occasionally stir until the sugar dissolves.
Let the syrup cool to room temperature before storing it in the refrigerator in an airtight container for up to 4 weeks.
For the Blackberry Bourbon Smash
Place 4 blackberries, 6 mint leaves, turbinado simple syrup, and lime juice in a cocktail shaker and muddle gently.
Add the bourbon and several ice cubes. Shake vigorously for 20 seconds.
Add a few cubes of ice to a glass. Remove the top of the cocktail shaker and pour everything into a double old-fashioned glass. Add additional ice.
Pour club soda on top. Stir and garnish with mint leaves and a lime wedge, if desired. Serve immediately.
Notes
Don't strain this Blackberry Bourbon Smash for the best sipping experience.
Serve this blackberry bourbon smash in a double old-fashioned glass so you have plenty of room for ice. After pouring the drink into the glass, I like adding a few ice cubes before topping it with club soda. Remember to stir!
Then, clap the mint before garnishing the cocktail to release the oils and fragrance from the mint, enhancing the cocktail experience.
