Watermelon Plum Mint Water: Easy Recipe

DetoxWater Editorial Team•Published November 5, 2026

Watermelon plum mint water is a fruit-and-herb-infused water that takes 2 hours 10 minutes total and makes about 1 liter (4 1/4 cups).

What is watermelon plum mint water?

Watermelon plum mint water is plain water steeped with pieces of watermelon, sliced plum and fresh mint. The fruit lends a mild sweetness and tartness, while the mint gives it a fresh finish; the ingredients are strained rather than blended.

It is one of many melon infused water recipes that add flavor to water without requiring a sweetener. The flavor is subtle compared with juice, and it develops as the pitcher chills.

What ingredients and ratio do you need?

For one pitcher, use:

  • Water: 1 liter (about 4 1/4 cups)
  • Watermelon: 110 g (about 3/4 cup), cubed, rind removed
  • Plum: 40 g (about 1/4 cup), thinly sliced, pit removed
  • Fresh mint: about 5 g (about 1/4 cup loosely packed, or 8–12 leaves)

The watermelon and plum together make about 1 cup of chopped fruit per liter of water. Choose ripe fruit for the fullest flavor, but avoid pieces that are bruised or spoiled. Leave the plum skin on for color and a slightly sharper flavor.

A covered pitcher or large jar and a strainer are useful. If your container is small, divide the ingredients between two clean jars and use roughly the same proportion of fruit and mint in each.

How do you make watermelon plum mint water?

Active prep: 10 minutes
Refrigerated steep: 2 hours
Total time: 2 hours 10 minutes

  1. Wash your hands, the fruit and the mint under running water. Clean the pitcher and any utensils you will use.
  2. Cut the watermelon into cubes, removing the rind and any seeds. Slice the plum thinly and discard its pit.
  3. Place the watermelon and plum in the pitcher. Gently press the mint leaves between your fingers and add them.
  4. Pour in the water, cover the pitcher and refrigerate for 2 hours.
  5. Strain the water into a clean container, or pour it through a strainer into glasses. Serve chilled.

For a stronger infusion, refrigerate the mixture for up to 4 hours before straining. Avoid mashing the watermelon if you prefer a clearer drink; small pieces of pulp can pass through a coarse strainer. Add ice to individual glasses rather than the pitcher if you do not want it to dilute the batch as it melts.

Why do watermelon, plum and mint pair well?

Watermelon has a gentle, sweet flavor that gives the drink its base. Plum adds a tangier note and can lend the water a little color, while mint keeps the finish fresh. Slicing the plum thinly exposes more of its flesh to the water without turning the drink into juice.

The combination brings together the mildness of watermelon infused water, the fruitiness of plum infused water and the herbal freshness of mint water.

The main benefit is hydration: the flavor may make plain water more appealing. There is no established evidence that this particular infused water has a special health effect. Whole watermelon and plum contain nutrients, but the amount that transfers into steeped water is uncertain; eating or blending the fruit changes what the drink contains.

How should you store watermelon plum mint water?

Keep the pitcher covered and refrigerated throughout steeping and storage. Drink the infused water within 24 hours for the best flavor, and discard it after 2 days or sooner if it becomes cloudy, slimy or sour-smelling.

Do not leave the pitcher at room temperature for more than a few hours. Straining after steeping helps limit further changes in flavor and makes the water easier to pour, but it does not replace refrigeration.

How can you vary watermelon plum mint water?

Make it fruitier

Use a little more plum and a little less watermelon while keeping the combined fruit close to 1 cup per liter of water. A ripe plum will give a softer, sweeter taste; a firmer one can be more tart.

Adjust the mint

Use fewer leaves for a softer herbal note, or gently press the leaves before adding them for a more noticeable mint aroma. Avoid tearing them into tiny pieces if you want easy straining.

Change the steep

Taste the water after 2 hours. If the flavor is too light, return it to the refrigerator and taste again before straining at 4 hours. The result will still be lighter than a blended fruit drink.

Frequently asked questions

Can I use frozen watermelon?

Yes. Use unsweetened frozen watermelon and add it directly to the pitcher. It may soften and make the water cloudier as it thaws.

Can I eat the fruit after steeping?

Yes, if it has been kept refrigerated and still looks and smells fresh. Its flavor may be milder after steeping.
