You can also combine bourbon, lemon juice, and sparkling lemonade in an ice filled glass and stir gently. Pour Blackberry-Rosemary Syrup so the dramatic color swirls down into the glass.
In a punch bowl combine 3 cups of the bourbon, 2/3 cup lemon juice, and one recipe of the Blackberry-Rosemary Syrup. Add 4 cups chilled sparkling lemonade. Garnish with frozen blackberries, if desired. Makes about 12 servings, each 5 oz.
