Add the vodka, basil, cucumbers and sparking lemonade to a shaker half filled with ice. Shake several times, pour into an IPA glass.
Pour beer into the glass, gently stir. Add cucumbers and basil. Serve immediately.
Notes
If you use lemon flavored sparkling water, or any other soda that is unsweetened, make sure to compensate for the lack of sweetness with about 1/2 ounce of simple syrup or agave.
