James White Prune Juice – A Deliciously Unique Drink. Whether you enjoy prune juice at breakfast or as an afternoon pick-me-up, treat yourself to a refreshing drink full of flavour. Award-winning prune juice stands apart from other fruit juices. It’s not made by simply squeezing fresh fruit; instead, slowly dried plums from varieties that are smaller and denser than the juicier eating ones are used. After rehydrating the plums, the juice is extracted to create a rich, full-bodied drink that’s virtually fat-free. Enjoy a wholesome, naturally flavourful juice any time of day.
