Watermelon Thirst Quencher Juice

Watermelon juice is so easy to make at home and a healthy way to stay hydrated during the summer. In this post, I share my best tips for picking a ripe watermelon and how to turn it into a nutritious watermelon juice.

I’ve noticed watermelon juice on menus at cafes and restaurants here in San Diego and I’m always surprised at how much they charge, which is usually around $3 a glass. I’ve been drinking watermelon juice at home for as long as I can remember and it’s super easy to make at home.

My mom introduced me to watermelon juice as a kid and it was our favorite drink during the summers because it really quenches your thirst. It makes sense, watermelon contains more water than any other fruit (about 91%) and its natural sweetness makes it a perfect fruit to serve as a thirst-quenching drink.

We loved it as kids and I make it now just like she did. So, when I see it at restaurants, I never order it because it’s easy and cheaper to make at home. It’s so refreshing and you can make a big batch and keep it in the refrigerator.

How to Pick a Watermelon

Before you make watermelon juice you will need to pick out a watermelon. I learned how to pick perfectly ripe watermelons from my mom who is pretty much a watermelon whisperer. She’s so good at picking them people ask for her help at the store.

The key to picking a ripe watermelon is the sound it makes when you rap on the bottom. When you hit the watermelon with the palm of your hand, you want to hear a hollow-like sound and you should hear a sound like water swishing through it. If you hear a very dull thud, those watermelons are usually mushy.

I always use this method to pick watermelons, like for my Avocado Watermelon Salad and it never fails.

Regular watermelons, with pink-red flesh, are easy to find but have you ever seen yellow watermelons? The flesh is a beautiful yellow color and they are a little sweeter than regular watermelons. You can use yellow watermelons to make this juice, too.

Ingredients for Watermelon Juice

My mom’s watermelon juice has just one ingredient: watermelon. I like to add a little fresh lime juice to mine because it gives it a fresh citrus-twist. You don’t need any added sugar as long as you are using fresh in-season watermelons. They are plenty sweet as they are, but you can always add sugar to suit your tastes.

My mom’s watermelon juice is a little different from others I’ve seen online because she uses both the flesh and part of the rind, which is full of nutrients and edible. Since the fruit and rind are blended together the watermelon juice is more like a smoothie since the rind makes it a little thicker.

How to Cut a Watermelon and Make the Juice

  • Cut the watermelon in half and then cut each half into slices.
  • Cut the slices into cubes, including the white portions of the rind. Slice as close to the skin as possible. You will have some all flesh cubes and some with the white portion (see the photo above). You can use both to make your watermelon juice.
  • Place the watermelon with the lime juice in a blender. Blend until the watermelon is pureed. Give it a taste and, if needed, add sugar, to taste.

How to Store Watermelon Juice

What I like about this watermelon juice is that I can make a big batch and keep it in the refrigerator. You can keep it in a large pitcher with a lid, but what I think is even better is to portion the juice out in mason jars. That way I have single-servings ready to go.

Also, since the pulp in the juice will settle, the mason jars make it really easy to just shake the juice up before I drink it since you can fit the jars with lids.

Fresh watermelon juice will keep in the refrigerator for up to three days. A big batch doesn’t last long at our house because we have some at every meal.

You can also make popsicles with watermelon juice which is a fun frozen treat. Check out my Watermelon Lime Ice Pops if you want to learn how to make them.

Growing up, during the summer months, my mom made us fresh watermelon juice to go with our meals. Watermelon contains more water than any other fruit, about 91% water. That makes it ideal for a fruit juice that will actually quench your thirst.

Ingredients:

  • 1 personal sized watermelon you can also use larger ones, just adjust the ingredient portions
  • juice from 1 lime
  • sugar optional, to taste

Directions:

  1. Slice open watermelon and cut into slices. Cut watermelon slices into cubes, including the white portions, as close to skin as possible (see the photo in the post). Save the sweet red portions for eating if desired, otherwise you can juice it as well.

  2. Add watermelon, lime juice, sugar if needed, into blender and blend at high speed until smooth. The pulpy portions may sink to bottom if juice is not consumed right away but you can always shake it again before drinking.
