How Long Does Coconut Water Last? Does It Go Bad?

Ever since it became trendy to drink coconut water for health benefits such as electrolytes and hydration, people want to know how long they can keep their opened bottles before they must be thrown out.

But does coconut water actually go bad?

What happens if you let it expire?

In this article, we’re going to explain the shelf life of a opened bottle of coconut water, including signs that indicate the product is no longer safe to consume.

Let’s explore whether or not your favorite beverage can really last too long — from fridge time limits all the way down into its expiration date.

What is Coconut Water?

Coconut water is the clear liquid inside a young, green coconut.

It’s often called “nature’s sports drink” because it’s packed with electrolytes and minerals, making it a great choice for rehydration.

Coconut water is also low in calories and fat, and it has a refreshing, lightly sweet taste.

Coconut water contains essential nutrients like potassium, magnesium, sodium, and calcium.

It’s also a good source of antioxidants and B-vitamins.

All of these nutrients are important for maintaining healthy fluid levels in the body and keeping your cells functioning properly.

Coconut water is naturally isotonic, meaning that it has the same concentration of electrolytes as our blood.

This makes it an ideal choice for rehydration after exercise or illness.

When we’re dehydrated, our bodies need fluids that can be quickly absorbed and used by the cells.

Coconut water fits this bill perfectly, which is why it’s often used in IV solutions for people who are unable to take in fluids orally.

So, what are the benefits of drinking coconut water? First of all, it’s a great way to stay hydrated.

Coconut water is also low in calories and fat, making it a healthy choice for those watching their weight.

Additionally, the electrolytes in coconut water can help replenish those lost through sweating during exercise.

And finally, the antioxidants and B-vitamins present in coconut water help support the immune system.

How Long Does Coconut Water Last?

Coconut water is a refreshing, healthy drink that is packed with electrolytes and nutrients.

But how long does it last?

Coconut water typically has a shelf life of about 2-3 days, but this can vary depending on a few factors.

If the coconut water is stored in a cool, dark place, it will last longer than if it is stored in a warm, sunny place.

Additionally, if the coconut water is refrigerated, it will last longer than if it is left at room temperature.

Once opened, coconut water should be consumed within 24 hours for best quality.

After that time, the flavor and nutrient content of the coconut water will start to decline.

However, it will still be safe to drink for another day or two after that.

So bottom line: coconut water lasts for 2-3 days unopened, and 24 hours after being opened.

But for best quality, drink it as soon as possible after opening.

How to Store Coconut Water?

Assuming you’re talking about store-bought coconut water, the best way to keep it fresh is to refrigerate it.

Coconut water can last unopened in the fridge for about a week or two.

Once you open the container, you should drink it within a few days.

If you’re wondering how to tell if coconut water has gone bad, the easiest way is to give it a sniff.

If it smells off or sour, it’s probably not good anymore.

You can also take a look at the color of the liquid.

If it’s darker than usual or has started to form clumps, those are both signs that it’s time to toss it out.

Of course, you can always extend the shelf life of coconut water by freezing it.

Just pour it into an ice cube tray and pop the cubes into a freezer bag once they’re frozen solid.

Frozen coconut water will last for several months, so this is a great way to keep it on hand for smoothies or other recipes.

How to Tell If Coconut Water is Bad?

It’s easy to tell if coconut water has gone bad.

The water will become discolored and have a sour smell.

The flesh of the coconut will also become softer than usual.

If you see any mold growing on the surface of the water, it’s best to discard it.

Can You Freeze Coconut Water?

Coconut water is a refreshing and hydrating beverage that is packed with nutrients.

Many people enjoy drinking it chilled, but you may be wondering if you can freeze coconut water.

The short answer is yes, you can freeze coconut water.

Coconut water can be frozen in ice cube trays or in freezer bags.

Freezing coconut water is a great way to keep it fresh and make it last longer.

When freezing coconut water, it’s important to use fresh and clean coconuts.

If the coconuts are old or not fresh, the quality of the coconut water will suffer when it’s frozen.

When choosing coconuts for freezing, look for ones that are heavy for their size and have brownish-yellow shells.

Avoid coconuts that are light in weight, have cracked shells, or have mold on them.

Once you have your coconuts, crack them open and scoop out the coconut water into an ice cube tray or freezer bag.

Freeze the coconut water for up to six months.

When you’re ready to drink it, thaw the coconut water overnight in the refrigerator or by placing the frozen cubes in a glass of cold water.


Coconut water is a relatively shelf-stable product, but it can go bad over time.

The main indications that coconut water has gone bad are mold growth, off-flavors, and increased viscosity.

To extend its shelf life, store coconut water in a cool, dark place in an airtight container.

If you notice any signs that your coconut water has gone bad, discard it immediately.
