Juicing is an excellent way to add a boost of vitamins and minerals to your diet. It’s a great way to get in those much-needed servings of fruits and vegetables that many of us struggle to consume. Making homemade juice is not only easy and convenient, but it’s also quite cost-effective. One of the most popular containers for storing homemade juice is a Mason jar. Mason jars are affordable, durable, and easy to find. However, many people wonder how long the juice will last in a Mason jar. In this post, we’ll dive into the topic and answer the question: How long does homemade juice last in a Mason jar?

The Factors That Impact The Shelf Life Of Homemade Juice

Several factors can impact the shelf life of homemade juice in Mason jars. The most important factor is the type of juice. Some types of juice last longer than others, depending on the ingredients. For example, citrus-based juices tend to have a shorter shelf life compared to juice made from vegetables. The amount of sugar and acidity in the juice can also affect its shelf life. Additionally, how the juice is stored and handled can also impact longevity, as bacteria growth can cause the juice to spoil more quickly.

How Long Does Homemade Juice Last In A Mason Jar?

In general, homemade juice lasts for two to three days in a Mason jar, if stored correctly. To ensure that your juice stays fresh and safe for consumption, it’s important to take a few measures. First, make sure to store the juice in a Mason jar that has been sanitized thoroughly. You can do this by washing the jar with hot, soapy water and then rinsing it with hot water. Alternatively, you can run the jar through the dishwasher.

Once the jar is clean, make sure to fill it with fresh juice to the top. Leaving too much empty space in the jar can increase the risk of bacteria growth and reduce the shelf life of your juice. Next, you’ll want to store the juice in the refrigerator as soon as possible. It’s best to store the juice in the coldest section of your fridge, as this slows down the growth of bacteria. Finally, to keep your juice fresher for longer, consider using a vacuum sealer to remove as much air as possible from the jar.

Tips For Extending The Shelf Life Of Homemade Juice

While homemade juice can last for up to three days in a Mason jar, there are some tips you can use to extend its shelf life. First, try to avoid using too many fruits in your juice, as they tend to go bad more quickly. Instead, focus on using more vegetables, which have a longer shelf life. Additionally, consider adding lemon juice to your juice, as the acid can help preserve the juice for longer. Adding honey to your juice can also help extend its shelf life, as it has natural antibacterial properties. Finally, always make sure to store your juice in a Mason jar that has been thoroughly cleaned and sanitized.


In conclusion, homemade juice can last for up to three days in a Mason jar if stored correctly. The type of juice, the amount of sugar, and how the juice is handled can all impact the shelf life of homemade juice. By following the tips outlined in this post, you can enjoy fresh homemade juice for longer. Remember to also take safety precautions when making and storing homemade juice to prevent the growth of harmful bacteria.

Can you store fresh juice in mason jars?

Yes, you can store fresh juice in mason jars, and they are actually a great option for storing your homemade juice. Mason jars are made of glass, which is a non-reactive material that won’t affect the flavor of your juice. Glass is also a much safer option than plastic, as it does not leach harmful chemicals into your drink.

When it comes to storing juice, there are a few things to keep in mind. First, it is important to use clean, sterilized jars to prevent any bacteria from growing. You can sterilize your jars by washing them with hot soapy water and then boiling them for 10 minutes.

Next, make sure your juice is fresh and has not been sitting out at room temperature for too long. It’s best to drink fresh juice right away, but if you need to store it, do so in the fridge. Keeping your juice chilled will help preserve its nutrients and prevent harmful bacteria from growing.

When filling your mason jars, leave a little bit of space at the top to allow for expansion if you plan on freezing your juice. If you are just storing in the fridge, fill the jar up to the top to minimize the amount of air in the jar.

Lastly, use quality mason jars with airtight lids, such as Ball or Kerr jars, to ensure that your juice stays fresh and does not leak. If you plan on transporting your juice, opt for plastic lids with a silicone ring to prevent any spills.

Mason jars are a great option for storing fresh juice. Just make sure to use clean jars, keep your juice chilled, and use quality airtight lids to keep your juice fresh and delicious.

How do you increase the shelf life of fresh juice?

Freshly squeezed juice is a popular beverage for health-conscious individuals. However, its shelf life is relatively short and it can spoil quickly due to the presence of microorganisms and enzymes. Therefore, it is important to increase the shelf life of fresh juice to extend its availability and ensure its safety.

One way to increase the shelf life of fresh juice is through refrigeration. Cooling the juice slows down the growth and activity of microorganisms, delaying spoilage. However, refrigeration alone may not be sufficient in extending the shelf life of fresh juice. The juice may still spoil due to the presence of enzymes that are not affected by cold temperatures.

Another method to increase the shelf life of fresh juice is through pasteurization. The process involves heating the juice to a specific temperature for a certain amount of time to inactivate microorganisms and enzymes. After pasteurization, the juice must be cooled and immediately packaged in a hermetically sealed container to prevent recontamination and extend its shelf life.

However, pasteurization may also affect the quality and nutritional value of fresh juice. The heat may cause changes in flavor, aroma, and color, and may degrade some of its beneficial compounds such as vitamins and antioxidants. To overcome these issues, some manufacturers use a process called cold pasteurization or high-pressure processing. These methods use pressure rather than heat to eliminate microorganisms while preserving the quality and freshness of the juice.

To increase the shelf life of fresh juice, it is important to use refrigerator storage and pasteurization, with the latter procedure used with discretion in order to preserve the beneficial compounds. Additionally, use of advanced processes, as explained above, is necessary to maintain the best quality while avoiding contamination and spoilage.

Does juice go bad if sealed?

Juice is a popular beverage packed with essential vitamins and minerals. While unopened juice can last for up to 12 months if stored in a cool dry place, it can eventually go bad if it is not refrigerated. The best way to ensure juice retains its high quality and freshness is to always refrigerate it immediately after opening. The freshness and quality of the juice will deteriorate in time due to light, heat and air exposure.

When juice is not refrigerated, it becomes a favorable breeding ground for bacteria, yeasts, and molds. Drinking spoiled juice can cause stomachaches and diarrhea, among other adverse side effects, which can pose severe health risks to the consumer. As juice contains natural sugars, prolonged storage, and exposure can cause the sugars to break down, forming alcohol, causing the juice to ferment, become alcoholic and turn into vinegar.

It is interesting to note that consuming juice that has not been properly pasteurized can also cause some severe health problems. Improperly pasteurized juice may have harmful microorganisms that cause foodborne illnesses. Unpasteurized juice can be a significant source of infection, especially to children, pregnant women, and those with weakened immune systems.

Juice can indeed go bad whether it is sealed or not, as a result of prolonged storage, heat, light, air, and contamination from harmful microorganisms. The best way to ensure that juice stays fresh for an extended period is to store it in a refrigerator as soon as it is opened and to consume it before the expiry date. Additionally, it is vital to note that unpasteurized juice can be harmful to health, and it is essential to avoid it altogether.
