You have a bottle of lemon juice sitting at the back of your fridge, and you’re probably wondering, “Does lemon juice go bad?” or “How long does lemon juice last?” Don’t worry; you’re not alone. Whether you’re looking to preserve the tart zing of freshly squeezed lemons or extend the life of a store-bought bottle, understanding the shelf life of lemon juice is crucial. So, let’s dive into it!

How Long Does Lemon Juice Last? It Depends!

The longevity of lemon juice can vary from as short as two days to up to a year, depending on the type of juice and how it’s stored. Broadly, lemon juice comes in three forms:

  • Handmade, Freshly Squeezed
  • Refrigerated, Store-Bought
  • Unrefrigerated, Store-Bought

Handmade, Freshly Squeezed Lemon Juice

Homemade lemon juice is the most perishable and should be consumed within two to three days. It doesn’t contain preservatives, making it susceptible to bacterial growth and quality degradation.

Refrigerated, Store-Bought Lemon Juice

With fewer preservatives than its unrefrigerated counterpart, refrigerated store-bought juice lasts a bit longer, around a week, before turning sour and unpalatable.

Unrefrigerated, Store-Bought Lemon Juice

These typically have a longer shelf life, thanks to preservatives and reduced water content. Expect these to last 3-6 months unopened or up to a year if stored in the fridge.

Remember to consider the best-before dates on store-bought juices. While they might still be safe for a few days after, they will lose flavor and nutritional value.

Whole Lemons

Whole lemons stay fresh for up to one week at room temperature and two to three weeks in the fridge. Freezer storage is also possible, but expect flavor degradation after three to four months. Once harvested, lemons don’t ripen, so don’t expect them to improve on your countertop.

Sliced Lemons

If you’ve sliced more lemon than you need, store the pieces in the fridge for 2-3 days or freeze them for up to 3 months. Just be aware that freezing could make them mushy.

Is Your Lemon Juice Risky? Warning Signs to Watch Out For


Mold may develop in lemon juice left at room temperature for extended periods. If you spot mold, it’s time to say goodbye to that bottle.


One of the most common signs of food poisoning, diarrhea could be a red flag that your lemon juice has been contaminated.

Abdominal Pain

Experience any abdominal cramping? This could signify you’ve consumed something you shouldn’t have.


Vomiting is another red flag for food poisoning. If it happens, seek medical advice immediately.

How to Spot Bad Lemon Juice: 4 Ways

  • Examine the Color: Fresh lemon juice is pale yellow. A darker shade might be a sign of spoilage.
  • Perform a Sniff Test: Fresh juice smells citrusy; a fermented smell indicates spoilage.
  • Take a Drink: A tiny sip can confirm if the juice has lost its lemony zest or turned sour.
  • Examine for Mold: Any mold or yeast is a surefire sign that your juice has gone bad.

Storage Tips: How to Extend the Life of Your Lemon Juice

Freeze It!

Pour your excess lemon juice into an ice cube tray and freeze it. You can later use just the amount you need.

Fridge First

Always store opened lemon concentrate and freshly squeezed juice in the refrigerator to keep it fresh for longer.

Choose Wisely

Select lemons with thin skins; they are usually juicier. Green lemons can be ripened at home in a paper bag.

Knowing how to properly store lemon juice can save you from wasting it and ensure that you’re making the most of its tart, refreshing goodness. Always remember to use your senses to check if it’s still good to consume, and when in doubt, throw it out!
