For two people, we usually drink half of our batches that evening, and then keep the rest in the fridge and finish it the next night! Use best judgment in terms of food safety with your extras, as unpasteurized juices (especially ones that are not served fresh) can be unsafe for certain people.

Potentially unpopular opinion? But I like to leave the WHOLE lime in the juice because the rind and pith of the lime gives a bitterness to the finished agua fresca that I think is so, so delicious. (Reminds me of this pie.) Also, since I don’t add alcohol to mine, this helps it feel slightly more like a cocktail. 🙂 If you’re not a fan of any bitter flavor, just use lime juice instead of whole limes.
