Coconut water, the clear liquid inside coconuts, has become a very popular beverage in recent years. With its sweet, nutty flavor and hydrating properties, coconut water makes for a tasty and refreshing drink. But how long does coconut water last after opening? Here is a quick overview:
Unopened Coconut Water
An unopened container of coconut water will typically last for up to 9 months past the printed expiration date, provided it has been stored properly in a cool, dark place. The key is keeping the container sealed and the coconut water from being exposed to air, light, or warmth for extended periods.
Opened Coconut Water (Refrigerated)
Once opened, coconut water exposed to air will slowly start to oxidize and lose flavor. However, refrigerating opened coconut water can help extend its shelf life. Here are some general guidelines for refrigerated coconut water:
- Carton – 5 to 7 days
- Bottle – 7 to 10 days
- Can – 10 to 14 days
The shelf life depends on the type of container. Bottles and cans provide more of an airtight seal than cardboard cartons. Also avoid storing opened containers right on the refrigerator door, where the temperature fluctuations can accelerate spoilage.
How to Tell if Opened Coconut Water Has Gone Bad
There are a few key signs that indicate your opened coconut water has spoiled and should be discarded:
- Change in color – Fresh coconut water is clear and colorless. If it starts to turn pink or yellow, that’s a sign it has gone bad.
- Off smell – Coconut water should smell pleasantly sweet. If you detect sour or rotten odors, toss it.
- Fizzing/bubbling – Seeing bubbles or fizzing inside your opened coconut water means fermentation has begun and it’s no longer safe to drink.
- Mold – The presence of any fuzzy mold spots also signals spoilage.
If your opened coconut water exhibits any of these traits, it’s best to play it safe and discard it. When in doubt, remember the old adage – when in doubt, throw it out!
Does Coconut Water Go Bad?
Yes, coconut water does eventually go bad, despite some claims that it has indefinite shelf life. Like any other perishable food or beverage, coconut water contains compounds that can spoil or degrade over time when exposed to air, light, warmth, and microbial growth.
While coconut water lasts longer than many other juices thanks to its naturally occurring antioxidants and nutrients, it doesn’t last forever. Consuming spoiled coconut water can potentially lead to upset stomach, diarrhea, or other gastrointestinal distress.
Tips for Storing Opened Coconut Water
Here are some tips for maximizing the shelf life of your coconut water once opened:
- Refrigerate – Keep opened coconut water as cold as possible, at or below 40°F.
- Avoid warmth – Don’t let it sit out on the counter or in hot environments.
- Use clean utensils – Always use a clean cup/glass and avoid double-dipping to prevent bacterial contamination.
- Reseal container – Close the cap, lid, or cover tightly after each use.
- Check for bubbles – Check the coconut water periodically and discard at first sign of carbonation.
- Don’t mix – Don’t mix newer and older coconut water, as this can spread bacteria.
Can You Freeze Coconut Water?
Yes, coconut water can be frozen successfully to extend its shelf life even further. To freeze coconut water:
- Make sure it is already refrigerated before freezing for best results.
- Pour coconut water into ice cube trays or other small freezer-safe containers.
- Leave at least 1⁄2 inch of headspace to allow for expansion.
- Freeze for up to 3 months.
- Thaw overnight in the refrigerator before using.
- Use thawed coconut water within 3-4 days.
Freezing prevents the coconut water from oxidizing or spoiling. Just be aware that freezing can alter the texture and taste to some degree. But it remains a handy method for longer term storage.
Does the Type of Coconut Water Impact Shelf Life?
There are a few main varieties of coconut water to be aware of:
- Young coconut water – From young, green coconuts. Most perishable.
- Mature coconut water – From older, brown coconuts. More prolonged shelf life.
- Pasteurized coconut water – Heated to remove bacteria. Lasts longer than unpasteurized.
- Concentrated coconut water – Has less water. Typically lasts longer.
Young coconut water has the shortest shelf life, lasting only about 10-14 days refrigerated when opened. Mature coconut water lasts a bit longer. Pasteurized and concentrated coconut water tend to have the most extended shelf lives thanks to processing and less water content respectively.
How Long Does Coconut Water Last at Room Temperature?
At room temperature, opened coconut water will only last about 1-2 days before going bad. The warmer temperature allows microbial growth and oxidation to accelerate much more quickly compared to refrigeration.
For best quality and safety, try to drink or use any opened coconut water within a day if you can’t refrigerate it. Discard any leftovers that have been sitting out beyond 24-48 hours to be safe.
Does Canned or Boxed Coconut Water Last Longer?
Between canned and boxed coconut water, canned generally lasts a bit longer if opened. A few factors contribute to this:
- Cans are more airtight than cartons.
- Canned coconut water is often pasteurized for added preservation.
- Aluminum cans don’t let in light which can degrade nutrients.
- Cartons are more prone to punctures and leaks.
An opened can of coconut water stored in the refrigerator should last 10-14 days. Cartoned coconut water will stay drinkable for 5-7 days. So opt for canned varieties if looking to stock up on coconut water with a longer shelf life.
Ways to Use Up Leftover Coconut Water
Don’t let opened coconut water go to waste! If you have some leftover nearing the end of its prime, here are some tasty ways to use it up:
- Make smoothies or protein shakes
- Blend into soups, sauces, or dressings
- Mix into batter for muffins or cakes
- Puree with fruits for popsicles
- Stir into oatmeal or overnight oats
- Use in place of water for cooking grains like rice or quinoa
Coconut water can seamlessly sub in for plain water in many recipes. Get creative with marinades, chia puddings, yogurt bowls, and more ways to use up your leftovers.
Frequently Asked Questions
Does coconut water need to be refrigerated?
Coconut water will last longer when refrigerated but does not necessarily need to be until opening. Sealed, unopened containers can be safely stored in cool, dry pantry conditions. However, refrigeration is recommended after opening to maximize freshness and prevent spoilage.
What happens if you drink expired coconut water?
Drinking expired coconut water puts you at risk for potential foodborne illness from bacteria growth. However, if the coconut water was properly stored and has been unopened, it should still be safe to consume for some time past its printed expiration date. If it smells, tastes, or looks off, err on the side of caution and discard it.
Does coconut water go bad in the fridge?
Yes, opened coconut water can still go bad in the refrigerator over time. Refrigeration simply slows down the rate of microbial growth and oxidation. Try to use opened containers within 7-10 days and check frequently for any signs of spoilage.
Can you drink 3 month old coconut water?
Drinking coconut water that is 3 months past its printed expiration but has been continuously sealed is generally safe. However, coconut water that has been opened for 3 months must be discarded, even if refrigerated. The quality and safety diminish rapidly once exposed to air and bacteria.
Does unopened coconut water expire?
All coconut water will eventually expire and has a limited shelf life. However, unopened coconut water lasts significantly longer, around 9-12 months at room temperature beyond any printed expiration date. Proper sealed storage is key for maximum shelf life.
Conclusion
When properly stored and handled, coconut water can maintain quality and fresh taste for an extended time, even after opening. Refrigeration, minimal air exposure, and careful monitoring for signs of spoilage are key to maximizing the shelf life. While it won’t last forever, following these guidelines can help you safely enjoy the delicious flavor and nutrition of coconut water before it goes bad.
