Juice In Mason Jars

How Long Can I Store My Juice?

A popular question from new juicers is how long can I store my juice? My answer is simple and straight to the point. Do not store your juice, consume it immediately after juicing. That way you get the maximum benefit without losing anything.

However, if you absolutely must store your juice then how long it will last depends on a variety of different factors including the type of juicer used, what fruits and vegetables you are juicing, the temperature you store it at, what you store it in and how soon after juicing you refrigerate it.

Let’s take an in-depth look at exactly what causes juice to degrade and how to get the longest possible storage time with minimal effect on the quality of the juice.

Heat Damage

The amount of heat created during juicing will depend on which type of juicer you are using and the speed at which that juicer juices. Centrifugal and Masticating juicers both generate heat, but centrifugal juicers generate more heat because they rotate faster than masticating juicers. This is one distinct advantage of masticating juicers.

Heat damages nutrients, but enzymes are particularly sensitive to heat. This is part of the reason long-life juices you can buy at the store aren’t as good for you as homemade juice. To increase shelf-life they have to pasteurize (which kills bacteria by heating), but that process also damages the beneficial enzymes. You really want to consume unpasteurized, raw juices.

Update: After researching this topic I am not convinced that the heat generated in juicing plays a big part in the degradation of juice. Sure it plays a part but I don’t think it’s a huge part of juice degradation. The heat generated, even by centrifugal juicers isn’t high enough to severely damage the nutrients and enzymes despite what juicer manufacturers may be saying. Oxidation however, is an entirely different matter!


Oxidation occurs during juicing because the juicer breaks the cell walls of the fruits and vegetables exposing them to the air. Substances in the cells react with the air producing oxidation. There is no way to juice without oxidization but centrifugal juicers are likely to produce more oxidation than masticating juicers because of the way they function.

But, oxidation doesn’t stop when you stop juicing. The longer the juice sits around, the more oxidation occurs. That’s why it’s important to drink your juice as soon as possible to get minimal oxidation and maximum benefit.

Sadly, drinking right away isn’t always practical or possible. I mean we all have to work, travel and can’t carry a juicer around with us 24/7 can we? Luckily, the amount of degradation can be slowed by understanding a few fundamental principles.

Fiber Slows Degradation

Juicing removes a lot of fiber but not all the fiber. Adding fiber or pulp back into your juice is a great way to increase the storage life of the juice in the refrigerator. Fiber helps prevent further oxidization which in turn will help the juice from degrading. The more fiber or pulp there is in your juice the longer it is likely to last in the fridge.

Smoothies tend to last longer because they contain more fiber. The soluble fiber in both juice and smoothies also helps your body to lower cholesterol and balance blood sugar naturally. A smoothie is really nice in the morning to get you started!

Citrus Juices Are Natural Preservatives

Citrus fruits are a good source of Vitamin C which is very good for your body. But did you know that Vitamin C is also known as ascorbic acid and is widely used as a food additive to prevent oxidation? If you’ve ever purchased apple slices you’re probably wondering why they don’t turn brown. The answer is they spray them with ascorbic acid!

This means that adding citrus fruits like oranges, lemons and limes to your juice will help them stay fresher longer. Just how much you add is a matter of taste but adding enough citrus juice will help slow degradation.

Another question I get asked all the time is should I juice citrus fruits with the peel on or off? The first thing to consider is did you buy organic or conventionally grown produce?

If it’s conventionally grown it’s wise to remove the citrus peel due to potential pesticide contamination. If you bought organic it’s really a matter of personal choice. Lemon and lime peel is digestable by humans but other citrus peels are not and may make your juice taste bitter.

Be sure to juice the pith from citrus fruits. The pith is the white layer under the peel that coats the fruit. It actually contains many nutrients like bioflavonoids.

Use An Airtight Glass Container

When storing juice in the fridge you want to use an airtight container and have as little air remaining in it as possible. The best thing to use is either a glass bottle or glass jar with a lid that forms an airtight seal. Also make sure that when storing your juice, you store it in containers that will hold just one serving as you do not want to keep opening and closing the lid letting air in.

Be sure to fill your containers to the very brim or maybe even overflow a little to minimize the air inside. My recommendation is that you never use plastic as plastic can leak toxins into the juice. Research has showed that even hard plastic containers leak toxins.

If you’re looking for the perfect juice containers try Balls Preserve Jars. I see many juicers using these jars and own a set myself!

Chill Your Juice

You always want to make sure your juice is cold. The colder the better but avoid freezing unless you absolutely need to. Don’t let your juice sit out of the fridge because that can encourage bacteria to grow in your juice which can make you very sick indeed.

Be prepared when juicing to get any unused juice in the fridge straight away. I sometimes place mine in the freezer for 5 minutes to get it nice and cool before placing it in the fridge. Just don’t forget and leave it in there too long or it will start to freeze!

How Long Can I Store My Juice?

I cannot stress this enough… Oxidation occurs the moment you start juicing. This is why it is important to drink the juice right after making it. If you have to store it, just remember that the longer it sits around the less benefit you are getting from it. That said, there is still a lot of benefit in drinking juice that has been stored correctly for a limited time so don’t think it’s not worth drinking juice that has been stored.

Here’s my opinion… if you’re using a centrifugal juicer don’t store your juice longer than 24 hours. If you’re using a masticating juicer don’t store your juicer longer than 48 hours. Try to drink it right away but if you must store it then use all of the above information to slow oxidation and degradation.

Smoothies are likely to keep longer because of the extra fiber. I wouldn’t store a smoothie longer than 72 hours. Remember, that all these storage times are estimates. Individual juices and smoothies may last less or more than these estimates. If you have any doubts about the state of your juice, throw it out and make a fresh batch. Fresh really is better!

A Final Word About Freezing

There is another way to store juice for longer periods and that’s to freeze it. For best results you need to freeze it as close to the time you juice it. This may be a good solution if you’ve made a lot of juice at once and can’t consume it in the near future. The freezing process will cause some damage but will keep it a lot fresher than if you left it in the fridge for a week!

You can make ice cubes or ice pops out of your leftover juice. These are quite refreshing but not everyone will enjoy a vegetable juice popsicle!

    Hi Denise,

    Thanks for the in depth article on storing juice. I saw the other day on a website where they said you could store it in the refrigerator for a week. Wow! Where did they get that from?

    We’re on the same page here, I drink it when I juice. But, when I have too, I store it in mason jars and only for 24 hours. It really does taste better to me when it’s fresh though. Thanks again and best wishes!

    • Reply Denise February 7, 2013 at 7:45 am

      The storage times I presented here are what I would use. There’s no saying you can’t store your juice for a week in the fridge, but I wouldn’t like to store it that long.

      Remember there’s a distinction to be made between the storage time before the juice actually spoils and is undrinkable and the storage time before you lose the advantage of juicing at home.

      What’s the point in spending all the time and money on a juicer and juicing if you just let it sit in the fridge and let all those nutrients and enzymes deteriorate?

      Fresher will always be better so aim for as little storage time as possible, that’s what I say!

    Excellent article Denise! I totally agree…drink your Juice right away if possible…if you can’t, store it in an airtight mason jar like you said for 1 to 2 days max depending on the kind of Juicer you use..I enjoyed reading this article, great info! Frank

    • Reply Denise February 7, 2013 at 7:50 am

      Thanks Frank! I know there are differing opinions on storing juice and how long you can store it.

      It’s my opinion that we all juice for a reason and that is to get the maximum health benefit we can from all those amazing fruits and vegetables.

      So it makes sense to drink the juice when we make it for maximum benefit and limit storage time to an absolute minimum!

    I was just wondering about freezing juice today. I have a masticating juicer and thought I’d make larger amounts and keep some in the fridge for later in the day or the next morning but so far I can’t stop myself from drinking it right away! It’s so good! Thanks for the great information.

    • Reply Denise February 13, 2013 at 9:59 pm

      Glad to hear you’re loving the juice! I don’t think i’ve ever frozen my juice to store it. It’s just so good fresh and I spent a lot of money on a juicer so that I could drink it fresh as possible. I have made juice popsicles but that’s because they are refreshing and not for storage reasons!

  • Reply Jared Brentlinger August 7, 2013 at 5:36 pm

    I have been raw juicing awhile now and use Ball Mason Jars. I NEVER store them more than 72 hours in the fridge after juicing. I also juice half a lemon or half a lime to slow oxidation with each mason jar I fill up to the top.

    I juice every other day so I try and keep it under 48 hours, but the juice still tastes great even at the 72 hour mark.

    Air-tight, out of direct sunlight, and stored in a fridge is the key to making it last.

    I have some beet juice that is stored in a plastic bottle for a week. Is it safe to drink or should I toss it and make fresh juice. I think I made too much or should have frozen it in small containers.

    • Reply Denise September 29, 2013 at 6:33 pm

      I would throw it out and make fresh. It’s always better to drink fresh juice but if you do make too much and think it may spoil it’s okay to freeze it. Freezing will damage some of the nutrients but it will keep it good to drink. It’s something I do from time to time although I prefer fresh juice.

    I have a question I have a breville juicers my mom as cancer and right now she’s in the hospital I had start her on juicing at home to get stronger because of some medicine she was very sick for 2weeks so she got very weak I want to bring some for her at the hospital but I work in the morning I would like to make it at night and bring with me in the after noon when I go should I freeze it to keep as much nutrients for her. I juice for her one apple, 3 celeri hand full spinach and kale. And the one she love is orange and mandarine. She will drink one but the other one will leave it for later. What’s the best way. And I brought only a small cooler with ice pack so no frig overthere. Thank you.

      Sorry to hear about your moms cancer. I have to mention that I am not a doctor and you shouldn’t take anything on this blog as a substitute for professional medical advise. While juicing is beneficial to many cancer patients, there are those such as patients with weakened immune systems where it could be potentially harmful. Obviously it’s advisable to talk over your moms nutrition and use of fresh juices with her doctor or oncologist.

      Please remember that produce should always be properly washed to remove or kill harmful bacteria and other pathogens before juicing. More on that here.

      I personally never drink juice that is more than 24 hours old and I always try to drink it as soon after juicing as possible. Freezing it will cause some of the nutrients to be lost but it’s still very beneficial to drink juice that has been frozen. It’s probably a good idea to freeze in your case as this will also prohibit anything nasty growing in the juice while it’s being stored. Hope this helps!

    Thanks for the great information.

    I have a theory about preventing oxidation within a container, I was wondering if you have any input.

    I juice regularly on Sunday to last from Monday until Thursday. In order to preserve the juice from going bad, I’ve been adding whole limes into the juice and putting the juice in an air tight container. The problem is that as the days pass, more air is available in the container which causes oxidation. So here’s the theory I want your input on, if I poured extra virgin olive oil over the juice to create a layer of oil on top of the juice, would that in fact prevent the juice from oxidation? Or what other methods of approach do you have in order to prevent oxidation within a container?

    Much thanks for your input,

    -Justin Kim

    At the end of the day, I appreciate the tidbit about adding citrus to increase storage life, however the article has not really covered the max length that fresh juice can be stored in a fridge and gives suggested consumption time but not max storage. There are a lot of very positive comments above, agreeing that fresh squeezed seems best, but none seems to answer the title of this article.

    Additionally, there are many comments about losing nutrients, presumably through oxidation, when it is stored for long periods or frozen, yet no % reduction in nutrition is quantified or duration when nutrients reduce.

    I would love to know exactly what is the longest I can safely store entirely vegetable-based juice close to 34F. I would hope it could be safe for up to a week, only if needed, and would be great to know when it has spoiled, such as looking for bubbles (fermentation), or stuff floating, or thickening of the juice. I honestly don’t know and I’m just guessing.

    My best guess is that organic carrots, kale, cucumbers, celery, and beets are good in their native fibrous form for up to two weeks, so I would expect slightly less times, maybe a week max, once they have been juiced.

    I’m very new to the world of juicing, it seems I have a lot to learn! If I juiced in the morning, stored it in a glass jar and kept it in my cooler lunch box (its insulated and I keep two ice packs and a couple of frozen water bottles inside daily), would it hold until lunch time?

    • Reply Denise July 14, 2015 at 7:34 pm

      You should be okay if you keep it cool and keep it in an airtight container.

    If I make fresh juice and immediately freeze it as ice blocks/popsicles, how long can I store it in a freezer ?
    There will be no additives, of any kind, in the end product, and, there will be little, or, no air in the containers.

    I was told that if you vacuum seal your juices in a 8oz Mason Jar it will last up to 7 days

  • Reply Meg January 27, 2016 at 1:26 pm

    I buy a lot of fresh juices and sometimes I do forget about half of it sitting in the .fridge for a few days sometimes. I got the juice I am drinking right now on Monday I believe and it’s not Wednesday. I can tell with my senses the quality isn’t as good, but bad fruits and veggies are a pretty distinct taste. Your guidelines make sense for best possible scenario, but I trust my senses and I don’t think there is anything wrong with a 72 hour juice, maybe longer which this one is, as I do not taste anything gone bad. This one has ginger and turmeric in it so I think I would at LEAST be getting the benefits from those.
    Also, I am glad you broke down the fiber thing, lots of sites mention fiber and effectiveness, but don’t really explain it the way you did, now it makes sense!

    • Reply Denise June 5, 2016 at 5:57 am

      I have to admit that I don’t like storing juice. It kind of defeats the object to juice and then shove it in a jar and let it sit for days and days. A lot of the benefits of juicing come from the enzymes that begin to break down the moment you break the cell walls. I know that you can drink juice right up until the point at which it’s spoiled but why bother? Why not just make a fresh new batch? Sorry for bashing storage, I know not everyone has the time or inclination to juice every day, I just think it’s a shame to let the good stuff sit and lose any of it’s benefit. Of course drinking juice will always be beneficial. So if you store it right, or freeze it, that’s still very worth while. But maximum benefit comes from freshly made juice. 🙂

    A committed juicer since 1995, I juice mostly vegetables, with apple & lemon or lime added to preserve. I store juices (refer) because of time restraints. Ever juice Spinach? If interested, pull up a chair. B EST METHOD: place baby spinach leaves into a regular blender (Oster or equal). Add a cup of water and blend. Next, add spinach & water to make a thicker liquid, to suit yourself! Blend for several minutes at higher speeds. Next, pour spinach liquid into a separating picture and let it stand until pulp rises to top. Drain off the dark green juice and drink, or store for later. I’ve developed this method and I can guarantee you–it works~! End result? Maximum fresh juice… Minimum pulp means …”Happy Juicer~!” Drink Up~!

      It makes sense to drink it fresh to get the maximum benefit from it, but I understand not everyone has the time to make fresh juice every day.
