Agua fresca means “fresh water” in Spanish, and that’s exactly what this is: fresh fruit blended with water into something more refreshing than the sum of its parts. I

n Mexico, you’ll find aguas frescas at taquerias, street carts, and at family gatherings, served from big glass jars called vitroleros.

Watermelon agua fresca (agua de sandía) is the most popular version. The fruit is sweet enough that you barely need added sugar, and the lime juice keeps it from being cloying. It’s the drink you want when it’s too hot to think.

This takes about 10 minutes to make and keeps in the refrigerator for a day or two. For parties, make a double batch. It disappears fast.

What Is Agua Fresca?

Aguas frescas are traditional Mexican drinks made by blending fruit (or other ingredients) with water, sugar, and often lime. They’re lighter than smoothies, more flavorful than plain water, and designed to be refreshing rather than filling.

You’ll find them everywhere in Mexico, from street vendors to restaurants to home kitchens. The big glass jars (vitroleros) filled with brightly colored aguas frescas are iconic images of Mexican food culture.

Common varieties include:

• Agua de sandía: Watermelon (this recipe)
• Agua de jamaica: Hibiscus flower
• Agua de horchata: Rice-based, cinnamon-flavored
• Agua de tamarindo: Tamarind
• Agua de limón: Lime

Each is made the same basic way: blend the main ingredient with water, sweeten to taste, strain if needed, serve over ice.

How to Make Watermelon Agua Fresca

• Cut about ⅛ of a large seedless watermelon into chunks (roughly 4 cups). Add to a blender with 1 cup cold water, ¼ cup sugar (or less to taste), and the juice of one lime.
• Blend until smooth. Taste and adjust sweetness or lime. Some people strain it; I don’t bother. The texture is fine without straining.
• Pour over ice or refrigerate until very cold. Stir before serving, as it may separate slightly.

Tips:

• Use seedless watermelon or you’ll need to strain
• Chill the watermelon beforehand for an even colder drink
• Start with less sugar and add more if needed. Ripe watermelon is often sweet enough on its own

Variations and Additions

• Mint: Add ¼ cup fresh mint leaves to the blender
• Chile-lime: Rim glasses with Tajín (chile lime salt)
• Ginger: Add a small piece of fresh ginger
• Cucumber: Replace half the watermelon with cucumber for a lighter version
• Sparkling: Top with sparkling water for fizz

Serving Agua Fresca

Serve in tall glasses over plenty of ice. Garnish with lime wedges or mint sprigs.

For parties, make a large batch and serve from a pitcher or drink dispenser. Aguas frescas look beautiful in clear glass containers, showing off the bright pink color.

Pair with tacos, grilled meats, or any Mexican food. The refreshing sweetness balances spicy dishes perfectly.

Watermelon Cocktail Version

For a spiked agua fresca:

The limoncello adds citrus depth without being overly sweet. You could also use tequila or mezcal for a more traditionally Mexican cocktail.
