This refreshing cocktail is a perfect choice for summer evenings. To create it, start with 2 ounces of Juniper Green London Dry Gin over ice in a lowball glass. Add an ounce of blackberry liqueur and sweeten to taste with a dash of agave nectar or simple syrup. Add a splash of sparkling water and stir. Garnish with a wheel of fresh, cool organic cucumber and a sprig of fresh basil leaves.
