Step 1

In a pitcher, combine pineapple juice and ginger. Cover and chill for at least 2 hours or up to 24 hours. Strain juice mixture, discarding ginger.

For each serving, pour pineapple juice into a tall glass over ice, filling each glass about three-fourths full. Add enough carbonated water to each glass to fill. If desired, garnish with skewered fresh pineapple.
