How do you increase the shelf life of fresh juice?

Drinking fresh fruit and vegetable juices is a great way to get important vitamins, minerals, and antioxidants into your diet. However, fresh juices only last for a day or two before going bad. Fortunately, there are steps you can take to extend the shelf life of your fresh juices by days or even weeks.

Why Fresh Juices Spoil Quickly

There are a few reasons why fresh juices have such a limited shelf life:

  • Exposure to oxygen – When juice is exposed to air, oxidation occurs which causes it to lose nutrients and taste worse.
  • Natural enzymes – Fruits and vegetables contain enzymes that help ripen them. Once blended, these enzymes start breaking down the juice.
  • Microbial growth – Fresh juices contain lots of nutrients which make a perfect breeding ground for mold, bacteria, and yeast.

While you can’t completely stop these effects, you can slow them down significantly by taking specific steps to extend the shelf life of your juices.

7 Tips to Extend the Shelf Life of Fresh Juices

Follow these methods to keep your juices fresher for longer:

1. Use Clean Produce

Always start with fresh, high-quality fruits and vegetables. Wash them thoroughly to remove dirt, chemicals, and microbes. Peel any waxed skins before juicing.

2. Juice in Smaller Batches

Only make as much juice as you plan to drink within a day or two. The more juice you make at once, the faster it will degrade.

3. Drink ASAP

For maximum nutrition and flavor, drink your juice immediately after making it. The longer juice sits, the more nutrients it loses.

4. Store in Airtight Containers

Pour your juice into a clean airtight container like a mason jar or reusable bottle with a tight lid. This minimizes exposure to oxygen.

5. Fill Containers to the Top

Leave as little air space as possible in your storage container. The more air bubbles, the more oxidation will occur.

6. Refrigerate Promptly

Keep juices refrigerated at 40°F or below to inhibit microbial growth and slow enzymatic reactions.

7. Freeze for Later

Freeze juice in small portions to have on hand for up to 6 months. Thaw overnight in the fridge before drinking.

How Long Does Juice Last Refrigerated?

With proper storage methods, you can expect your fresh juices to last:

Juice Type Refrigerator shelf life
Citrus juices (orange, grapefruit) 3-5 days
Apple juice 3-5 days
Carrot juice 2-3 days
Leafy green juices (kale, spinach) 1-2 days
Mixed fruit and vegetable juices 1-3 days

Citrus juices tend to last the longest since they are acidic, while delicate greens degrade most quickly. Always refrigerate juice immediately after making it.

How to Tell if Juice Has Gone Bad

Check your juice for the following signs of spoilage before drinking:

  • Unpleasant sour or bitter odor
  • Fizzy bubbles
  • Cloudy appearance
  • Mold visble anywhere in the bottle
  • Slimy texture
  • Undesirable changes in color

If your juice exhibits any of these characteristics, it is no longer safe to consume and should be discarded. When in doubt, remember the old adage – “When in doubt, throw it out!”

Can You Refreeze Thawed Juice?

It is not recommended to refreeze thawed juice. During the initial freeze, ice crystals rupture cell walls and release enzymes. These enzymes kickstart chemical reactions that degrade quality and nutrients. Refreezing thawed juice can also allow more microbial growth.

If you can’t finish thawed juice within a day or two, your best option is to toss it out. Only freeze portions you know you will consume.

Juice Storage tips

To maximize the shelf life of your fresh juices, be sure to:

  • Start with clean, ripe produce
  • Juice in small batches
  • Drink juice ASAP after making it
  • Store in airtight containers
  • Minimize air exposure
  • Refrigerate immediately
  • Freeze extras in portions

Following these simple guidelines, you can enjoy optimally fresh, nutritious juice for up to a week in the fridge or 6 months in the freezer.


Drinking freshly made juices provides an easy way to consume essential vitamins, minerals and antioxidants. However, their freshness quickly declines once exposed to air, enzymes, and microbes. By promptly refrigerating juice in airtight containers and minimizing air bubbles, you can extend the shelf life by days or weeks. Additional storage time can be achieved by freezing smaller portions. With proper handling, it is possible to enjoy optimally fresh juices for maximum nutrition and flavor.
