Quick answer: Watermelon juice is made by blending about 3 cups (450 g) of seedless, chilled watermelon cubes for 20–30 seconds, then straining if you want a pulp-free glass. It is roughly 92% water, naturally sweet, hydrating and low in calories, and it is best drunk fresh within 24 hours.
What is watermelon juice and why is it so popular in India?
Watermelon juice is simply the liquid from blended watermelon flesh. With no added sugar it tastes like liquid summer, and it is one of the most popular coolers across India from March to September. It needs no cooking, no special skill and only one ingredient, which is why it has become a staple of home kitchens, offices and gyms.
The challenge is usually the equipment. A full-size mixer is heavy to wash for a single glass, and street-style juice is rarely made hygienically. A rechargeable portable juicer solves both problems: you blend one fresh serving in seconds and rinse the bottle in under a minute.
What are the benefits of watermelon juice?
Watermelon is more than water. Here is what a glass typically offers:
- Hydration: about 92% water plus natural electrolytes such as potassium, helpful in Indian summers.
- Lycopene: the antioxidant that gives watermelon its red colour, often studied for heart and skin health.
- Citrulline: an amino acid that some small studies link to reduced muscle soreness after exercise.
- Vitamins A and C: support immunity and skin.
- Low calories: around 45–50 kcal per 150 g of fruit, so a large glass stays light.
These are general nutrition facts, not medical claims. Juice is a tasty addition to a balanced diet, not a cure for anything.
How do you make watermelon juice at home?
Ingredients (1 large glass)
- 3 cups (about 450 g) chilled seedless watermelon cubes
- 5–6 mint leaves (optional)
- 1 tsp lemon juice
- A pinch of black salt or chaat masala (optional)
- Ice cubes to serve
Method
- Cut watermelon into cubes and remove any seeds. Chilled fruit gives a colder, thicker juice.
- Add the cubes to your juicer bottle, filling up to the max line only.
- Add mint and lemon juice.
- Blend for 20–30 seconds until completely smooth.
- Strain through a fine sieve for pulp-free juice, or drink as is for extra fibre.
- Pour over ice, add a pinch of black salt and serve straight away.
Because the bottle is compact, you can blend and carry it to work. The NEWDRU 450ml Portable Wireless Juicer & Blender handles a single serving in one go, while the NEWDRU 700ml Portable Juicer with Double Lids suits larger glasses or sharing.

What are the best watermelon juice variations?
- Watermelon mint cooler: add 8–10 mint leaves and a squeeze of lime.
- Watermelon ginger juice: add a 1 cm piece of ginger for a warming kick.
- Watermelon cucumber juice: blend with half a cucumber for an extra-hydrating drink.

- Watermelon lemonade: top with sparkling water and lemon juice for a mocktail.
How long does fresh watermelon juice last?
Fresh watermelon juice tastes best within 30 minutes and should be consumed within 24 hours if refrigerated in a sealed bottle. It separates naturally, so shake before drinking. If it smells sour or fizzy, discard it. Never leave it at room temperature for more than an hour or two in hot weather.
Are there any side effects of watermelon juice?
For most people, a glass a day is fine. Keep these points in mind:
- It contains natural sugars, so people managing diabetes should check with their doctor and watch portions.
- Very large quantities can cause bloating or loose stools in some people.
- People on potassium-restricted diets should ask a doctor first.
Key takeaways

- Drink fresh, or refrigerate for up to 24 hours in a sealed bottle.

Frequently asked questions
Is watermelon juice good for you?
Yes, in moderation. It is hydrating, low in calories and provides lycopene, vitamin C and potassium. It lacks the protein and fibre of whole meals, so treat it as a refreshing drink, not a meal replacement.
Can I make watermelon juice without a juicer?
Yes. Mash cubes through a sieve or use any blender. A portable juicer is the quickest option for a single glass.
Should I add sugar or water?
No. Ripe watermelon is sweet and watery enough. Adding water dilutes the flavour; a little lemon or mint lifts it instead.
Can I drink watermelon juice at night?
You can, but because it is high in water you may need to wake for the bathroom. Many people prefer it in the morning or afternoon.
Can I blend watermelon seeds?
Black seeds are edible but can make juice gritty and bitter. For a smooth juice, remove them first.
