Pour coconut water and yuzu juice over ice. Separately, whisk matcha powder with about 1 oz of hot water until smooth.
Carefully pour the matcha shot over the coconut water and yuzu juice mix to create a layered effect. Stir gently to combine flavors if desired, and garnish with a mint or basil leaf. Optionally, muddle some mint or basil leaves before adding the coconut water for extra depth of flavor. Enjoy immediately!
