Pro Tips
- Choose the sweetest watermelon: look for a yellow ground spot, heavy weight, and hollow sound when tapped
- A pinch of sea salt amplifies the sweetness and adds a trace of sodium for better hydration
- Pour into popsicle molds for frozen treats that are incredibly hydrating
- Add a few fresh mint leaves before blending for a spa-like experience
- No need to strain — unstrained watermelon juice has a slightly thicker texture with more fiber

Frequently Asked Questions
Do I need a juicer for watermelon juice?
No! A regular blender works perfectly because watermelon is so soft and watery. Blend for 30 seconds and you have juice. Strain if you want it smooth, or drink it as is.
How long does watermelon juice last?
Fresh watermelon juice should be consumed within 24 hours and kept refrigerated. It ferments quickly, especially in warm temperatures. If it smells yeasty or fizzy, discard it.
Can I freeze watermelon juice?
Yes! Freeze in ice cube trays, popsicle molds, or even freezer bags. Frozen watermelon juice cubes are great for adding to water — they flavor and chill your drink as they melt.
Is watermelon juice high in sugar?
Watermelon juice contains about 9-10g of sugar per cup — less than orange juice (21g) or apple juice (24g). Its high water content means the glycemic load is low. It's one of the healthiest juice options available.
Why add salt to watermelon juice?
A tiny pinch of salt (not enough to taste salty) enhances sweetness perception and provides sodium for better hydration. This is a traditional practice in many cultures and mimics the electrolyte balance of sports drinks.
