Prune juice typically lasts about 7 to 10 days in the fridge after opening, if stored properly in a sealed container.
Prune juice is a nutrient-packed beverage known for aiding digestion and promoting gut health. But like all perishable foods, it has a limited shelf life once opened. Proper storage is key to maintaining its freshness and nutritional benefits.
Prune Juice Shelf Life in the Fridge
An unopened bottle of prune juice can last for months when stored in a cool, dark pantry. However, once opened, its shelf life decreases significantly due to exposure to air and bacteria.
Opened Prune Juice Refrigeration Guidelines
- 7-10 days – Standard shelf life for commercially produced prune juice
- 5-7 days – For homemade prune juice (no preservatives)
- 3-4 days – If transferred to another container
For best results, store prune juice in its original airtight container. If you must transfer it, use a clean glass jar with a tight-fitting lid. The best glass pitchers can help maintain freshness while allowing you to monitor juice quality.
Signs Your Prune Juice Has Gone Bad
Watch for these indicators that your prune juice should be discarded:
Visual Changes
- Mold growth (fuzzy spots)
- Cloudiness or sediment

Smell and Taste

Extending Prune Juice Freshness
Follow these tips to maximize your prune juice’s shelf life:

Freezing Prune Juice
For longer storage, freeze prune juice in:
- Ice cube trays (for smoothies)
- Small freezer-safe containers
