How long does coconut water last?
How long does coconut water last? Unopened coconut water typically has a shelf life of:
  • Shelf-stable (pasteurized) coconut water: 6-12 months, depending on the brand and packaging. Always check the expiration date on the packaging.
  • Refrigerated coconut water: About 1-2 weeks, though it's best to follow the expiration date provided by the manufacturer.

Once opened, coconut water should be consumed within:
  • Refrigerated coconut water: 1-2 days.
  • Shelf-stable coconut water: 3-5 days.

Always refrigerate coconut water after opening, and check for any changes in taste, smell, or appearance, which can indicate spoilage.
How to preserve coconut water?
To preserve coconut water and extend its shelf life, follow these tips:
Unopened Coconut Water
  1. Store in a Cool, Dry Place: Keep shelf-stable coconut water in a pantry or cupboard away from direct sunlight and heat.
  2. Refrigeration: If you purchase refrigerated coconut water, keep it in the fridge until you are ready to open it.

Opened Coconut Water
  1. Refrigerate Immediately: Once opened, coconut water should be refrigerated at all times.
  2. Use Airtight Containers: Transfer the coconut water to an airtight container if the original packaging is not resealable.
  3. Consume Quickly: Try to consume opened coconut water within 1-3 days to enjoy its best flavor and quality.

Freezing Coconut Water
  1. Freeze in Portions: Pour coconut water into ice cube trays or small containers for easy thawing and use.
  2. Seal Properly: Use airtight, freezer-safe containers or freezer bags to prevent freezer burn.
  3. Thaw Safely: When ready to use, thaw coconut water in the refrigerator or use the frozen cubes directly in smoothies or beverages.

Pasteurization
For homemade coconut water, you can extend its shelf life by pasteurizing it:
  1. Heat Treatment: Gently heat the coconut water to 70-75°C (158-167°F) for about 15-20 minutes.
  2. Cool Quickly: Immediately cool the pasteurized coconut water by placing the container in an ice bath.
  3. Refrigerate: Store the pasteurized coconut water in the refrigerator and consume within a week.

By following these methods, you can help ensure that your coconut water remains fresh and safe to drink for as long as possible.
