Watermelon Agua Fresca (or Agua de Sandia) is a delicious way to quench your thirst. This is one of the easiest Mexican aguas frescas to make at home too.
Ah, summertime! What better way to cool off than with a tall glass of this refreshing drink?!
This popular beverage is not only mouthwateringly delicious but also full of nutrients. Let me share my secrets for making the perfect “watermelon water” that’s sure to be a hit at any summer gathering.

- Ripe Watermelon
Almost all agua frescas are made with only three ingredients: ripe fruit, water, and sugar.
That’s it. Contrary to popular belief, there is no caffeine in agua frescas.
You might also see “Agua de Sabor” or “Flavored Water” on the menu in Mexico. This means they have agua fresca, and you need to ask them what type they have available.
Note: “Agua Fresca” literally translated means “Fresh Water.”
- Chop up a ripe watermelon.
- Or buy a fresh watermelon that has already been chopped.
How to choose a ripe watermelon?
Look for the yellow spot. This is the spot where the watermelon was resting on the ground. If it is yellow, it is ripe. If it is white, it still needs time to ripen.
Also, look for “webbing” or brown strips around and across the watermelon. This means the watermelon is sweet from the bees pollinating.
If the tail is still on the watermelon, it should be dry. If it is still green, that means it is not fully ripe.
- Add the watermelon to a blender.
- The blended watermelon mixture will be thick.
- Strain the mixture through a mesh sleeve into a bowl.
- Pour the strained mixture and remaining water into a large pitcher.
This is also the time to taste the mixture. I only used 1 tablespoon of sugar to start.
Sometimes, it needs more sugar. Other times, it doesn’t even need sugar. This depends on the watermelon you choose, and how sweet the fruit is.
If the drink is too sweet, add more water to adjust.
Straining really depends on you and your blender. Some blender will blend the fruit completely. For a smoother texture, strain away.
Sweetener equivalent: 1 teaspoon Stevia for 1 tablespoon sugar.
To make this refreshing drink diabetic-friendly, use Stevia instead of white sugar. Any sugar substitute would work too.
How long does Agua Fresca Last?
- It lasts up to 4 days in the fridge.
To make it last longer, add lime juice. The acid in the lime juice will help preserve the drink. Just know that it will change the flavor slightly.
Also, try adding mint to your agua fresca.
To freeze, place in a sealable freezer bag and remove as much air as possible. Seal tight before placing in the freezer. It stores well for up to 5 months. When ready to consume, thaw and enjoy. Or, you can even make popsicles. Yummy!
