Delicious Watermelon Juice

Watermelon juice can be purchased from your local grocery store, or it can easily be made at home during the warm summer months when watermelons are plentiful. The shelf life of a watermelon is quite long when stored in a cool location such as in your fridge. But once the watermelon juice has been created, it doesn’t last quite as long.

How long does watermelon juice last in the fridge?

There are two versions of watermelon juice, one is the kind that you buy at the grocery store. To determine how long it will last in the fridge, reference the sell-by date on the container. This will give you a good rule of thumb.

The second type of watermelon juice is homemade watermelon juice. Usually when it is stored properly in an airtight container in the fridge, homemade watermelon juice will last approximately three days in the fridge. Keep in mind that watermelon juice is going to be the best in flavor and overall texture when it is enjoyed fresh.

Fresh Watermelon Juice Storage Tips

Room Temperature. Watermelon juice is likely to last between one and two hours at room temperature. After watermelon juice is created, it should be stored in the fridge for the best results.

A good rule of thumb is that watermelon juice should not remain at room temperature any longer than two hours before it goes bad.

In the Fridge. The best way to store fresh juice is in the fridge. The best, easy method is to store the watermelon juice in an airtight container, an air-tight food storage container, or our favorite, sealed securely in a mason jar with a lid in the fridge.

This will give you the best overall results. When homemade watermelon juice is stored properly in the fridge in an airtight container, it will last up to three days, but it’s best when enjoyed fresh.

In the Freezer. You can also freeze watermelon juice if desired. To freeze it, you will want to seal it securely in an airtight container, seal it in a plastic freezer bag, or use an ice cube tray to freeze the watermelon juice in smaller portions, then transfer the frozen cubes to freezer bags.  

Watermelon juice will likely last up to three months in the freezer at 0°F or below for the best results.

Homemade Watermelon Juice

Before you begin making homemade watermelon juice, you will want to select a ripe watermelon. This is a trick to getting a delicious juicy watermelon to make sure that it is ripe and ready to make into your refreshing drink. 

To tell if a watermelon is ripe, you can look for a yellow spot on the watermelon. This is said to indicate ripeness. While many people have different methods on how to tell if a watermelon is ripe, this is one where you can determine if it is a good one. You don’t have to do any kind of fancy footwork, or tap your head and then tap the watermelon, to tell if it’s ripe.

Watermelons, in general, have a high water content, which is one of the things that make them so delicious, and also a fabulous option to make juice. Let’s look at our easy recipe below, that you can follow to make this delicious juice at home.

Easy Watermelon Juice Recipe


Whole Watermelon. We recommend using a seedless watermelon to make juice, that way you don’t have to pick out the black seeds from the watermelon before making it into juice.

Lime Juice. Adding lime juice is optional, but we do recommend adding a splash of freshly squeezed lime juice to your watermelon juice which will help enhance the overall flavor.

If you don’t have lime juice, you can substitute lemon juice as well. Another option is to use a little bit of orange juice if desired.

Fresh Mint Leaves. Adding a sprig of fresh mint leaves into your finished juice is optional, but it does give your watermelon juice a delicious depth of flavor, which taste delicious.

Sweetener. Watermelon has its own natural sugar in it, which makes it taste juicy and delicious. However, while there is no need for added sugar, you can add some if you would like your watermelon juice to be on the sweet side. You can add simple syrup as a good sweetener option, or maple syrup as a natural sweetener option.

How to Make Watermelon Juice

1. To make watermelon juice you want to take a sharp knife and cut the watermelon to separate the melon from the watermelon rind. It’s a good idea to cut it into smaller pieces or watermelon cubes if possible. If you prefer you can use a melon baller to scoop out the inside of the watermelon.

2. Place the cut watermelon into a blender. Add the lid to the blender, and then blend until the pieces are smooth. 

3. Pour the watermelon juice through a fine mesh strainer, to remove any watermelon flesh.

4. Serve your fresh watermelon juice over ice cubes and enjoy! 

Frozen Watermelon

There’s nothing quite like a juicy summer watermelon, but did you know that you can also make watermelon juice out of frozen watermelon? Using frozen watermelon instead of fresh watermelon is an especially refreshing treat, because the frozen pieces form more of a smooth texture, making it a delightful frozen drink.
