Our original hop water is simply premium hops and water. Its brewed and carbonated like a craft beer with multiple hop additions and carbonated in the bright tank. Because there are no grains (sugars) or yeast, its naturally zero alcohol, zero calories and gluten free. All of the complex citrus and other flavors comes from the hops. Astoundingly refreshing and low on bitterness. Winner of the Beverage Innovation of the Year Award by Beverage Industry Magazine. Twist off cap.
