What is an agua fresca?
An agua fresca is made up of cool, fresh water blended with fruit, flowers, grains or seeds. This sweet, non-alcoholic juice is believed to have first been created by the Aztecs from muddled fruit. Through time, these beverages became popular throughout Mexico and nowadays are made in all sorts of flavors and varieties.
In the U.S., you will also find big containers of watermelon, melon, horchata and other kinds of these tasty drinks in Mexican restaurants and taquerias.
The great thing is that with just a blender and fruit, you can easily make your own aguas at home without a problem.

Ingredients & Substitutions
- Watermelon: Either a seedless watermelon or one with seeds will work. Just follow the steps below to ensure you have a ripe watermelon.
- Water: The key to this recipe is to not add too much water. Watermelon is already made up of so much water that adding too much more will dilute the final product and you won't get that delicious flavor.
- Ice: Similarly we only use a small amount of ice so the flavor is not diluted.
- Sweetener (optional): If you use a small amount of water and ice plus a ripe watermelon, there is no need for sweetener. However, as I have outlined below, there are instances when sweetener may be needed.

How to Pick a Ripe Watermelon
A ripe watermelon is key as it will yield the sweetest, most flavorful results. Here are some tips on how to pick the right watermelon:
- Choose one that has a creamy, yellow spot (called a field spot). This indicates the watermelon was resting on the ground longer and therefore will be ripe.
- Pick up the watermelon and choose one that is heavier for its size. This means it will be sweeter because it will be juicier.
- Look at the stem area and be sure it is not green, but instead looks dry. If it is green, that means the watermelon was picked too early.
- Pick a watermelon that has webbing or brown marks. These marks are caused by bees during pollination. The more scars, the sweeter the fruit will be.
How to Cut a Watermelon

Vitamix Blender
I use my high-powered Vitamix every day. It blends so well that there is no need to strain.
How to Make Agua De Sandia
1. Prep the Watermelon: Wash and cut the watermelon into large cubes.
2. Blend: Add water and the watermelon to the blender. Blend until smooth.
3. Strain if Needed: If you're using a high-powered blender, like a Vitamix, you won't need to strain the juice. However, other blenders might leave a fibrous pulp behind or some of the seeds, so you’ll want to use a fine mesh sieve or cheesecloth to strain it.
4. Chill and Serve: Pour the drink into a pitcher or bottle. Add 1 cup of ice, then place it in the refrigerator until cold. If you want to serve it right away, you can also serve the drink over ice. Don't add ice to the whole pitcher though as this will dilute the juice. Instead, add ice to each glass when you serve it and drink immediately.
Other Serving Suggestions
- Serve in a pitcher and clear glasses so the beautiful color can be on full display.
- Garnish each glass with a piece of watermelon.
- You can also mix in pieces of a watermelon into the pitcher for another garnish idea.
How to Store
Store in an air-tight bottle or other container for up to 3 days. The pulp will settle at the bottom so give the bottle a quick shake before serving.
Tips and Variations
- Freeze and blend the watermelon cubes with water to create a frosty version.
- Taste before adding sweetener so you don't add too much. Start with one tablespoon, blend and taste. Then, add more if needed.
- Refrigerate the watermelon before blending. This will help your agua cool down faster at the end, lessening the time in the refrigerator or the need for ice.
- Rim your glass with lime juice or chamoy and Tajin chile powder for a delicious, spicy addition.
- You can also blend with lime juice and/or garnish with mint leaves for another variation.
FAQ
You shouldn't have to add sugar if you follow the tips on how to choose a watermelon. A ripe watermelon adds all the sweetness necessary for a perfectly sweet watermelon agua fresca.
If you get a watermelon that is just not sweet enough for this recipe, then you can add sweetener. You can use white sugar, however, I prefer to use unrefined sugars which are a little less processed and retain more minerals. I recommend using monk fruit sweetener, coconut sugar, date syrup, or honey. Just keep in mind that date syrup and honey will alter the final flavor just a bit.
Overrripe and mealy watermelons are great for agua fresca. These are the watermelons that usually ended up as agua when I was growing up. They might not be the best for eating, but when blended, the mealy consistency disappears and the sweetness shines through.
If you buy a watermelon with seeds, just pick out the seeds before blending. I know this can be a bit of a hassle though, so you can definitely leave the seeds in. Some of the seeds will become pulverized when blending, which will make your agua fresca even more nutritious since the seeds are packed with lots of vitamins and minerals. Then, after blending, strain the liquid with a mesh sieve or cheesecloth to get rid of any extra seeds.
