What Are Chaga Mushrooms and How Long Do They Last

Chaga mushrooms live off the majestic birch tree. A unique fungus, this King of Herbs grows over a period of many years, resulting in nutrient rich health-giving components.

Chaga has a rich history to be proud of. This medicinal mushroom marvel stands apart as an ancient healer, and was widely recognized for hundreds of years by folk medicine.

In a world filled with all kind of dietary supplements, we look to chaga as a wellbeing contributor and a natural patron for better health. In fact, chaga mushrooms have one of the highest levels of antioxidants among all natural foods. This discovery assists us today with our need for health alternatives and wellbeing enhancers.

Did you know chaga is now revered as a superfood? This diamond of the forest sits happily among the other vegetables, herbs and berries, now seemingly trendy in this classification, however chaga extract mushroom and it derivative products are no trend.

Chaga tea is here to stay and is a is formidable competitor.

Once introduced to this powerful supplement, many people go on to speak of its many benefits with the consensus being that there is something very special about chaga. We must ensure chaga stays with us for centuries just as its ancient discoverers intended.

The Importance of Correctly Prepared Chaga

Once the chaga hunter sources and harvests the mushroom, it must be processed and prepared well to retain the best inherent qualities.

Like all complementary wellness products, the less intervention, the better.

How to harvest chaga?

Retaining the nutrient levels is paramount to having chaga enhance our health in the best possible way. Wrong preparation can lead to microbial growth and poor nutritional characteristics of the harvested mushroom. After harvesting, the finest chaga should be lab tested to ensure it is sanitary.

Remember that Chaga raw absorbs moisture, and should be dried correctly once harvested. Ideally, the moisture level should be around 14% or below. Any excessive moisture will attract mold and eventually chaga will simply rot.

The right suppliers are all important in the chaga industry. Chaga tea made from poorly preserved chaga chunks or powder, is likely to cause issues and possible unwanted effects.

Reputable chaga suppliers want to help you achieve your personal health goals and want better health for everyone, not simply sell a product. So our advice is to look for pure, and properly prepared chaga.

The best suppliers manufacture and process the chaga products from high quality sources. Look for a company with decades of experience, and a willingness to preserve only the beneficial nutritious elements of chaga. If you have any doubts – ask questions about how chaga mushroom was harvested, prepared and stored.

Through their dedication when harvesting, all the way through to advice and support, you will be able to tell the difference between a good and an indifferent. Sustainable harvesting, proper preparation and a trustworthy supplier ensures chaga will be with us for a long time. Chaga is a fantastic health booster. Let’s keep it that way!

Harvesting for the Best Outcome

At first glance, chaga mushrooms look like something that is difficult to call a mushroom. For the uninitiated, the growth or conk on the tree looks ominous, and almost something to avoid, however, beneath the rough black surface lies a flavored and nutritious substance which supports better health and well-being across the world.

The finest chaga can be found in the clear, pollutant free environments of birch forests in Siberia. Chaga’s hosts, the birch trees are healthy, and stand tall and proud in this environment. It is important to mention that Chaga mushroom properties absorbs pollutions and environmental toxins, so areas with cooler and cleaner air are best. Locations outside of large cities are preferable, and excellent places for growing the finest quality chaga mushrooms.

Chaga cannot be harvested from the birch tree roughly or without understanding that any damage, not only affects the chaga mushroom itself, but the living birch tree.

This care in handling equates to longevity of the product and the best consumer experience on all levels.

To ensure retention of the active, and beneficial ingredients chaga needs to be harvested correctly by true professionals with an understanding of the above key points.

Chaga, sometimes called, a gift from nature helps us to support our health. The respect shown when harvesting this King of herbs must be evident in the quality of the end products.

How to Store Chaga

Naturally, we all would like the best things in life to last as long as possible. How devotees feel about chaga is no different. So, how do you store Sayan chaga to ensure longevity?

Chaga’s rough outer exterior may suggest otherwise, but this mushroom actually contains moisture. It’s the moisture content in chaga that can cause issues if not stored correctly.

Another thing to keep in mind is that complementary health supplements chaga tincture are best used as fresh as possible. Like all food stuffs, it is wise to be aware of any ‘best before’ and ‘use by’ dates on the packaging. This ensures the freshest supplement for the consumer.

The more common question seems to be “how long does chaga tea last”? or “does it have a shelf life”?

We should start by saying that properly dried Chaga needs be brewed and cannot be consumed in its just harvested form. Not only is it unpalatable, but the human body cannot digest chaga in this way.

There are few different ways of storing chaga chunks or powder so it will retain health supporting properties for long time.

After drying it is best to store chaga chunks or ground powder in an airtight container. You can also store chunks in cloth bags which will allow chaga chunks to “breath”. Chunks or powder needs to be stored in dry dark place at room temperature. You can store chunks in refrigerator but we believe that this method doesn’t bring any extra benefits.

If you store chunks in sealed plastic bag, make sure that it won’t be left under the sun. Direct sunlight will make chunks “sweat”. You may notice small water drops inside the bag which potentially could make chaga perish. If it will be exposed to sunlight for a long period of time this water will increase chances of go bad. Most consumers will never see any bad reaction of chaga, but this kind of neglect will see many issues prevail.

Another way to preserve your chaga is to use a vacuum sealer. By removing the air from the package, you eliminate the chance of insects and moisture from your storage solution. There are a number of different vacuum sealers on the market which are perfect for domestic use.

What about storing after brewing?

Chaga mushroom powder tea can lose its potency after initial brewing, so it is recommended that chunks or powder be used only twice. After you brew your chaga, you need to dry it if you are going to use it again. You may not have an equipment at home to check for humidity levels, so just make sure chunks or powder are dry to the touch.

If you have a large amount of chaga you can freeze any unused portions after drying them out. Some people say that freezing the mushroom helps better preserve its potency and flavor, though this is still up for debate amongst the chaga community. Think about your chaga usage carefully. Plan your brewing and only use as much as you will need so you won’t need to re-use chunks or powder again.

If you wish to order chaga tea online, for the purposes of re-using, keep in mind that the size of the chunks could vary. Most packages of the mushrooms offer chunks which are medium or large in size. Uniformity is rare. It is really impossible to get all chunks with the same size since they all are chopped by hand.

Look for excellent quality chaga. If so desired, you should look how much “black crust” is included on the packaged chaga. Sayan exclusively offers all chunks with most beneficial outer “black crust” layer, our product offers you the purest, potent and powerful Siberian chunks!

If you follow these simple rules, either chaga chunks or powder could last you for a long time. It may seem unimportant, but for those who don’t plan on drinking the tea regularly but would like to buy a large quantity of chaga to get a discount, it’s important to know how long chaga tea can last so you can plan accordingly.

By now you are probably wondering what about already made chaga tea? Can I store it in liquid form? Yes, you can. But it is not recommended to store chaga tea after brewing for longer than 24 – 48 hours. Good analogy would be black, green or herbal tea. You probably would not enjoy drinking a tea which was made yesterday, right? We all like it fresh! How it should be stored? We would recommend to store it in thermos or keep it in refrigerator in glass container.

If you prefer to brew first and store later, another way how to store chaga tea can be frozen ice cubes. You can use them next time as an ingredient for your favorite flavored beverages.

You can also make up chaga tea enhanced teas with flavorings of your choice and freeze as a completed drink. There are many ways to enjoy frozen chaga. When brewed, this mushroom offers us a tonic full of immune system support.

Storing Chaga Extract

Since we’ve spoken about about chaga chunks and powder, take a moment and consider the storing of chaga extract powder.

Sayan chaga extract powder is made by a freeze-drying process. It conveniently, is a ready to use product. There’s no need to brew this type of chaga product.

Simply open the package, take out a measure of powder with a spoon and add it to your favorite juice, tea, coffee, smoothie, shakes or even soup.

You can store chaga extract in the same way as chunks but keep in mind that in general, the shelf life of extract is approximately two years. This can make it a better product for long term use.

Does Chaga Go Bad?

Naturally occurring foods spoil the same way as any processed food. There are no preservatives in natural foods (for good reason) therefore they perish sooner.

What should you look for? Best practice is to let your senses be your guide. Any growth or powdery substance on or in the chaga may be mold.

Mold on food is a microscopic fungus. Certain molds will appear as spots or patches, and others will resemble a powdery substance. The present of any kind of mold of consumable products needs further evaluation. Be aware that some kinds of mold can make you very sick. Chaga effects aims to help with health, not hinder it.

Does chaga go bad? It’s a concerning thought, especially today where we are all conscious of the food and beverages we consume.

Freshness, and the ability to ensure we are getting the best quality are all high on the list of priorities. Those new to chaga can learn from those with more experience.

Trial and error is a great teacher, but when it comes to food, and food storage, failure to recognize good preparation can cause a negative experience. If you treat chaga with the respect it deserves, you can enjoy your chaga for months and years to come.

Sayan, always guarantees high-quality products. Order our Siberian Chaga and your health will thank you!

Shelf Life

Ordering a large quantity and storing it for use later can be a great way to save money on your favorite variety of high-quality chaga tea. But you need to be aware of common storage pitfalls. The shelf life of chaga will depend on how it is treated and stored.

In general, most chaga products have a shelf life of one to two years. Coffee or teas that people blend may have a shorter shelf life and they often have limitations due to other ingredients in the tea.

Be sure to check expiry dates. These dates are located somewhere on the packaging. If you are unsure, please contact the manufacturer to obtain some advice.

Remember that It is illegal in USA to sell food product without an expiration date!

If you harvest chaga mushrooms yourself, write the date you purchased the chaga on the bag and make a note to consume it all for up to a year after that date.

In order to maximize your product’s life, ensure to adhere to all the necessary precautions. Keep it dry, cool and away from the sunlight.

Be sure to use these suggestions, common sense and follow the manufacturer’s guidelines.

    • Hello Hunter,

      Chaga mushrooms should be always dried out before storing. If you stored it only for a few days then we highly recommend drying Chaga mushrooms that you harvested. If chaga mushrooms are stored for a long period of time, we don’t recommend using them.

    • Hello Saarenas,

      Each product has its own direction. All directions are listed on the product page. If you are referring to Raw Chaga chunks or powder, then 2-3 cups (250-300ml cup) per day would be just fine

  1. Hello – I harvested a decent chunk of chaga a few weeks ago in Northern WI. After preparing some tea with a part of the fresh harvest, I managed to forget about the other chunk that I left outside, on our back porch; it has been out there for 2 weeks (part of which has been above freezing temps, but staying dry). Upon trying to make some tea with that (perhaps a bad idea), I noticed a bleach-like smell coming from the brew – has my forgetfulness compromised the remaining portion of the chaga? At a glance, it looks ok, and is still fairly hard on the inside, but that smell is really throwing me. I noticed that the chunks got quite spongy after being in water for only a few minutes.

    Thanks for your help!

    • Hello Zach,

      If you have noticed a bleach-like smell coming from the brew then we would recommend not to use this Chaga mushroom. We are not sure what and when something went wrong but Chaga should not have any bleach-like smell.

  2. I picked a chagga in winter that was covered in snow. I believe was chagga but the outside black was wet. Is that ok? A bit of the inside was spongy but dried very well with. I can break some pieces with my hands will it still be good to drink?

    • When you harvest Chaga mushroom, you should dry it at 14% humidity before you can brew it. If Chaga is wet or not cleaned we don’t recommend using it. If Chagais brittle, then we wouldn’t recommend using it. Usually, good dried Chaga chunks are very hard to break with hands, you can take out small pieces, but you can’t easily break it into many pieces with hands.

  3. I am relatively new to Chaga. I live in the Great North Woods of WI.
    My friend gave me some Chaga that was harvested off our property and I am addicted.
    I drink it everyday. I have done detoxing and cleanses before but nothing has ever compared to Chaga.
    I am now walking our property everyday looking for it. I have found several large pieces that I have harvested only about 1 pound off of to insure not to kill the tree and to hopefully let the Chaga continue to grow.
    At first I was only looking up in the trees until I found one about 4 inches off the ground. That Chaga was very wet and smelled of mold. I scrapped all the inside off so it doesn’t smell of mold anymore.
    I have 2 questions:
    First is the Chaga that smelled of mold still good even though I took all that smelled of mold off?
    Second I found Chaga on a live Birch tree that was spongy on the inside. Is Chaga that is spongy still good to brew?

    • We harvest Chaga which is at least 5 feet off the ground. When you clean up Chaga and dry it properly the humidity level should be less than 14%. We don’t recommend using Chaga mushroom which has a humidity level above 14%. The inside of the Chaga mushroom should not be spongy, it should have the consistency of tree bark or at least as a cork. Also after drying Chaga should not smell or has mold on the surface.

  4. I have a huge chunk of chaga that I just cut in half. The middle I can break up myself. Does that mean it’s gone bad or punky? It looks dry and it smells like nothing. But it did have a little white surface mold that I cut and brushed of with a dry brush.

    • How long the chunk was stored? If prepared and cleaned properly Chaga could be stored up to 2 years. If you see white surface mold most likely the Chaga stored incorrectly and we wouldn’t recommend using it.

  5. I came across some pure Chaga I’ve had frozen in my freezer for 7 years. It looks good I hate to throw it out it was a gift when I had colon cancer. I forgot about it and I wonder if I can still use it. It was absolutely more and I believe it came from Minnesota. My email is

    • Hello Ken,

      The Chaga mushroom will lose all its health benefits after 2 years of storage. You can use the Chaga which you have only for decorative purposes. We would not recommend using it.

  6. Thank you for your help. What about microwaving Chaga to warm it up? I know microwaving Broccoli kills at good portion of the nutrients. I’m sure you haven’t studied the science of this, but would you recommend heating it in the microwave, or do you think it is most likely to kill some of its goodness?

  7. how long can you leave brewed Chaga (Chaga that has been steeped already into a tea) unrefrigerated? I accidentally left it out over night on my kitchen counter and wonder if it still safe to drink.

    • Keeping chaga just overnight outside of the refrigerator is OK. But we won’t recommend storing brewed Chaga tea more than 12 hours without refrigerating. If you keep it in refrigerator would recommend storing brewed Chaga tea no more than 36-48 hours in order to minimize bacterial overgrowth.

  8. netI harvested my chaga 2 years ago. Leff the conchs in a open ( dark) plastic bag in the garage and took out, chopped and prepared inbatched of two weeks. I still have some that where harvested two years ago. They are dry for certain.Are they still good

    • Thank you for your question. We don’t recommend to store raw chaga more than two years. But if you want to use it you would need to check how dry chunks are and if there is any contamination. But general advice would be not to use it. Thank you!

  9. I have stored my Chaga nuggets in the freezer in a paper bag for about 9 months. Would it still be okay to use?

    • Hello Laura,

      It depends on harvesting date. If these chunks were harvested in 2015 than i would not use them. If you bough chaga chunks from us please look on expiration date on the back of the package, if the product is expired, than obviously you can’t use them. If you bought chunks from other company than it would be up to you to decide.

      Best Sayan
