Lemon juice is a staple in many kitchens, adding a zesty kick to everything from salad dressings to cocktails. But how long does lemon juice last in the refrigerator? Whether you’re using freshly squeezed or store-bought juice, understanding its shelf life is key to maintaining its flavor and quality.
Freshly Squeezed Lemon Juice
How Long It Lasts: Freshly squeezed lemon juice can last up to four days in the fridge when stored in an airtight container. It’s important to minimize its exposure to oxygen and microorganisms to prevent spoilage.
Best Practices:
- Airtight Container: Always store fresh lemon juice in a sealed container to keep out air and contaminants.
- Refrigerate Promptly: Place the juice in the refrigerator as soon as possible after juicing.
- Minimize Air Exposure: The less air exposure, the better. Use the juice soon after juicing for the best flavor and quality.
Signs of Spoilage: If your lemon juice develops a strange odor, changes color, or shows signs of mold, it’s time to toss it out.
Store-Bought Lemon Juice
Unopened Bottles: An unopened bottle of store-bought lemon juice can last for several months past its best-by date if stored in a cool, dark place away from direct sunlight and heat. These bottles are typically pasteurized, which helps to extend their shelf life.
Opened Bottles: Once opened, bottled lemon juice can last for 6-12 months in the refrigerator, thanks to preservatives and pasteurization. Make sure to reseal it tightly after each use.
Best Practices:
- Refrigerate After Opening: Always refrigerate store-bought lemon juice after opening.
- Tightly Seal: Ensure the bottle is tightly sealed to prevent air and bacteria from getting in.
- Check the Date: While it can last past the best-by date, it’s always a good idea to use it before that date for the best quality.

What to Do with Lots of Lemons
If you find yourself with an abundance of lemons, don’t let them go to waste. Here are some tips to make the most of your citrus bounty:
- Freeze the Juice: Pour lemon juice into ice cube trays and freeze it for up to three months. Once frozen, transfer the cubes to a freezer bag for easy storage. Use the frozen cubes as needed in drinks, soups, or other recipes.
- Make Lemonade: Whip up a batch of homemade lemonade. It’s a refreshing way to use a lot of lemons at once, and you can store it in the refrigerator for several days.
- Infuse Water: Add lemon slices or juice to your water for a refreshing and healthy drink. Infused water can be stored in the refrigerator for a few days.
- Cook or Bake: Use lemon juice in various recipes, from salad dressings and marinades to cakes and pies.
- Three-Ingredient Sorbet: You can also make a simple three-ingredient sorbet and use the citrus peels as bowls.
Signs That Lemon Juice Has Gone Bad
Even with proper storage, lemon juice will eventually spoil. Here are some signs to watch out for:
- Change in Color: If the lemon juice becomes significantly darker or changes color, it may be a sign of spoilage.
- Strange Odor: A sour or off-putting smell is a clear indication that the juice has gone bad.
- Mold: Any visible mold growth means the lemon juice should be discarded immediately.
- Off Flavor: If the lemon juice tastes noticeably different or “off,” it’s best to err on the side of caution and throw it away.
Tips for Maximizing Lemon Juice Shelf Life
To get the most out of your lemon juice, follow these tips:
- Use Clean Utensils: When handling fresh lemon juice, use clean utensils to avoid introducing bacteria.
- Avoid Cross-Contamination: Do not drink directly from the bottle of store-bought lemon juice. Pour the desired amount into a separate container to avoid contamination.
- Store in the Coldest Part of the Fridge: Keep lemon juice towards the back of the refrigerator, where it is coldest.
- Consider Freezing: If you can’t use the lemon juice within the recommended time frame, freezing is a great option for extending its shelf life.
Conclusion
Whether you opt for fresh or store-bought lemon juice, understanding how to properly store it is essential for preserving its quality and flavor. Freshly squeezed juice should be used within a few days, while store-bought varieties can last much longer with the help of preservatives and pasteurization. By following these guidelines, you can ensure that your lemon juice stays fresh and flavorful for all your culinary creations.
