How Long Does Kombucha Last in Fridge? Tips to Keep Your Kombucha Fresh

If you’re a kombucha lover, you know how important it is to store this probiotic drink properly. One of the most common questions that kombucha enthusiasts ask is: how long does kombucha last in fridge? Keeping your kombucha in the fridge can definitely extend its shelf life, but for how long? In this article, we’ll discuss the ins and outs of kombucha storage and help you find the answer to this important question.

Kombucha has become increasingly popular over the years due to its numerous health benefits. It’s a fermented tea beverage that contains beneficial bacteria and yeast, and is known for its immune-boosting and detoxifying properties. However, since it’s a living organism, it can be tricky to store correctly. Temperature, light exposure, and air circulation all play a big role in kombucha’s shelf life. So, to help you make the most out of your kombucha experience, we’ll explore the different factors that determine how long kombucha lasts in the fridge.

If you’ve ever tried kombucha before, you know it’s a drink that’s best served chilled. Refrigeration is essential in keeping the probiotics in the drink alive and well. When stored properly, kombucha can last for weeks, even months. But when left at room temperature, kombucha’s lifespan is significantly shorter. It’s even possible for the drink to go bad and spoil if left out for too long. If you’re wondering exactly how long kombucha lasts in the fridge, we’ll delve deeper into the specifics of storing this delicious drink.

What is Kombucha?

Kombucha is a fermented drink that has been gaining popularity in recent years due to its health benefits. It is made by combining sweetened tea with a symbiotic culture of bacteria and yeast, also known as a SCOBY. Over time, the bacteria and yeast feed on the sugar and metabolize the tea, resulting in a fizzy, tangy, and slightly sour liquid. Kombucha typically has a low alcohol content, ranging from 0.5% to 3%, depending on the brewing process and length of fermentation.

What are the health benefits of drinking kombucha?

Kombucha, a fermented tea drink, has been garnering popularity over the years because of its numerous health benefits. Here are some of the health benefits you can expect from drinking this probiotic-rich beverage:

  • Aids digestion: Kombucha is a probiotic drink, which means it is teeming with good bacteria that can aid digestion. It can help improve gut health by regulating bowel movements and reducing inflammation in the gut.
  • Boosts immune system: Drinking kombucha regularly can help strengthen the immune system by increasing the body’s production of cells that fight off infections and diseases.
  • May protect against certain diseases: Kombucha is rich in antioxidants that help fight free radicals that can damage cells in the body. Regular consumption of kombucha has been linked to a reduced risk of heart disease, diabetes, and certain types of cancer.

In addition to these health benefits, kombucha is also a low-calorie alternative to sugary drinks, making it a healthy option for those looking to manage their weight.

How long does kombucha last in the fridge?

While kombucha has a long shelf life, proper storage is important to ensure its quality. Unopened bottles of kombucha can last up to six months, while opened bottles can last for up to a month in the fridge. However, it’s important to note that the taste and quality of kombucha may start to deteriorate after a few weeks in the fridge, so it’s best to consume it as soon as possible for optimal taste and health benefits.

Kombucha Shelf Life Unopened Opened
Room Temperature 1-3 months 7-10 days
Refrigerated Up to 6 months Up to 1 month

Storing kombucha properly is essential for maintaining its quality. To extend its shelf life, keep it in a cool and dark place away from direct sunlight and high temperatures. Additionally, make sure to check the expiration date on the bottle before buying and consuming it.

How is kombucha made?

Kombucha is a fermented tea that has been enjoyed for centuries due to its many health benefits. To make kombucha, you’ll need a few essential ingredients – water, sugar, tea, and a SCOBY (Symbiotic Colony of Bacteria and Yeast). Here’s a step-by-step guide on how to make kombucha:

  • Boil water and add in tea leaves. Allow to steep for 5-10 minutes, then remove tea bags/leaves.
  • Add sugar to the tea while still hot and stir until it dissolves.
  • Allow the sweetened tea to cool to room temperature.
  • Place the SCOBY on top of the tea and cover with a cloth or paper towel. It’s important to use a clean utensil and hands during this process to avoid contamination.
  • Let it sit undisturbed in a warm, dark place for a week to a month. During this time, the SCOBY will eat the sugar and ferment the tea, creating a fizzy and tangy drink.

It’s important to note that kombucha should be brewed in glass jars and should be kept in a well-ventilated area to avoid a buildup of carbon dioxide. The fermentation process will result in some sediment at the bottom of the jar, which is a sign that the kombucha is fermenting correctly. After the fermentation process is complete, you can then add flavors or fruits to your kombucha to make it even more delicious.

How long can kombucha last on the shelf?

Kombucha is a fermented drink made from tea, sugar, and a symbiotic culture of bacteria and yeast, commonly known as SCOBY. When stored properly, kombucha can last for several months on the shelf. However, several factors can affect its shelf life, such as the sugar content and the strength of the tea used during fermentation. This section will discuss the average shelf life of kombucha and the factors that affect its longevity.

  • The average shelf life of commercially-bottled kombucha is around 3 to 6 months. This is because these products usually contain added flavors, which can affect the drink’s acidity and carbonation over time.
  • Homemade kombucha can last up to 6 months on the shelf, but this depends on several factors. The strength of the tea, the sugar content, and the fermentation time are important factors to consider. Kombucha that has been fermented for a longer period tends to last longer on the shelf, as it contains less residual sugar.
  • The storage temperature is also a critical factor in determining the shelf life of kombucha. Ideally, kombucha should be stored in a cool, dark place, away from direct sunlight and heat. Exposure to high temperatures can cause the drink to spoil more quickly.

It is important to note that the quality of kombucha may deteriorate over time, even when stored properly. Signs of spoilage may include a sour or vinegary taste, cloudiness, or an off odor. When in doubt, it is best to discard any kombucha that appears to be spoiled.

In summary, the shelf life of kombucha varies depending on several factors. However, when stored properly, kombucha can last for several months. As with any food and beverage product, it is essential to pay attention to the signs of spoilage and consume only fresh and properly stored products.

Is it safe to drink expired kombucha?

Kombucha is a delicious, fizzy drink that has been enjoyed for centuries. The fermentation process creates a tangy, sweet, and slightly vinegary flavor that can be quite addictive. However, just like any other food product, kombucha has a shelf life. Kombucha should be consumed within a certain period to ensure that it is safe to drink and to get the best flavor profiles. Once the expiration date passes, it’s common for people to wonder if it is safe to drink expired kombucha.

  • First, let’s define the term ‘expired.’ Kombucha is a fermented product, which means it contains live cultures. The expiration date on the bottle refers to the recommended timeframe within which the kombucha is at its best. After this date, the taste may change, and the beneficial bacteria could begin to decrease.
  • However, drinking expired kombucha is generally safe. The acidic, low pH environment of kombucha prevents the formation of harmful bacteria such as E. coli and Salmonella, making it less prone to spoilage.
  • It’s important to note that drinking expired kombucha may come with a loss of taste, texture, and health benefits. After its expiration date, the beneficial probiotics that aid in digestion, boost immunity, and improve gut health might have reduced potency, so you may not experience the same benefits as consuming fresh kombucha.

If you choose to consume kombucha that has passed its expiration date, be sure to use your senses when checking for any signs of spoilage. If the flavor, color, or texture has significantly changed or there’s a funky odor, it’s probably best to toss it out.

Ultimately, it’s better to drink fresh kombucha and consume it within its recommended timeframe. Be sure to store it correctly in a cool, dark place, away from direct sunlight, and keep it refrigerated once opened to extend its shelf life.

What are the signs of bad kombucha?

Kombucha is a fermented drink that is made by adding bacteria and yeast to sweetened tea. The fermentation process can take anywhere from a few days to a couple of weeks, depending on the temperature and other factors. Once the fermentation process is complete, the kombucha can be bottled and refrigerated for later use. However, it is important to keep in mind that kombucha can go bad, just like any other food or beverage. Here are some signs that your kombucha has gone bad:

  • Off smell: One of the most obvious signs that your kombucha has gone bad is an off smell. If your kombucha smells like vinegar or something else unpleasant, then it is likely that it has gone bad.
  • Mold: Another sign that your kombucha has gone bad is the presence of mold. If you notice any white or green spots on the surface of your kombucha, then it is likely that it has been contaminated with mold. Mold can be harmful to your health, so it is important to discard any kombucha that has been contaminated.
  • Cloudy appearance: Kombucha that has gone bad may also appear cloudy or have sediment at the bottom of the bottle. This may indicate that the fermentation process was interrupted or that the kombucha was not properly refrigerated.
  • Unpleasant taste: Kombucha that has gone bad may also have an unpleasant taste. If your kombucha tastes sour or overly acidic, then it is likely that it has gone bad.
  • Explosive bottle: Another sign that your kombucha has gone bad is if the bottle becomes explosive or violent. This can happen when the fermentation process is not properly controlled, or if the kombucha has been contaminated with harmful bacteria.
  • Expiration date: Lastly, it is important to check the expiration date of your kombucha. Most commercially available kombucha will have an expiration date on the bottle, and it is important to discard the kombucha if it has passed its expiration date.

How to Properly Store Kombucha in the Fridge?

Kombucha is a delicious and healthy drink made from fermented tea. While it may have a reputation for being fussy and unpredictable, storing it properly in the fridge can help extend its shelf life and preserve its flavor. Here are a few tips:

  • Store unopened kombucha bottles in the fridge. Kombucha will continue to ferment even in the fridge, but at a much slower rate. Keeping it cold will help slow down the fermentation process and prevent the bottles from exploding.
  • Keep kombucha away from light. UV rays can degrade the quality of the drink, so it’s best to store it in a dark, opaque bottle or keep it in a cupboard or refrigerator drawer.
  • Avoid storing kombucha next to other strong-smelling foods. Kombucha can absorb odors from other foods in the fridge, so be sure to store it away from particularly fragrant items like cheese or fish.

If you’re making your own kombucha at home, here are a few additional tips for storing it:

  • Allow the Kombucha to fully ferment before placing it in the fridge. The colder temperature will slow down the fermentation process, regardless of whether it has already been bottled or left in the brewing vessel.
  • Decant the kombucha before storing. Decanting the Liquid from the sediment helps to extend the shelf life of the kombucha. It also helps to keep the flavor profile uniform.
  • Use a seal-tight container. Air is the enemy of kombucha, and it can cause the drink to spoil quickly. Mason jars, growlers or flip-top bottles are perfect for storing opened kombucha.


By properly storing kombucha in the fridge, you can keep it fresh and delicious for as long as possible. Keep it cold, store it away from light, strong smells, use seal-tight containers, and decant the kombucha first before keeping.
