General storage recommendations
It is important to store homemade mushrooms in glass jars correctly, since the harvested products have direct contact with the soil, and one should not fully rely on proper sterilization. If the storage regimes and terms are not observed, putrefactive bacteria and the botulinum virus, which releases a deadly poison - botulinum toxin, can multiply in the canned product.
Note! When the botulinum virus multiplies, the appearance and taste of the preserved food does not change in any way.
Shelf life of canned mushrooms
Mushrooms are an excellent dietary product, with a large amount of vitamins C, B, PP, potassium, iodine, and carbohydrates. Therefore, it is one of the favorite products for many. Fortunately, you can can them yourself or buy them ready-made.
If you bought it in a store, the expiration date will be indicated on the product label. The product must be marked according to GOST: type of mushrooms (whole or cut), method of preparation, storage temperature and expiration date . When purchasing canned mushrooms, pay attention to the quality of the liquid, i.e., the transparency of the marinade. It should be light, colorless or yellowish. Before purchasing, consider the contents of the jar; there should be no dark spots on the mushrooms.
Shelf life of pickled mushrooms
Let's consider the shelf life of homemade mushrooms under different storage conditions for containers with products, lids used and preservation methods.
Without refrigerator
Mushrooms canned in glass jars under plastic lids are stored without refrigeration for no more than 1 month, under metal and glass lids - no more than 3 months. The place where containers are stored can be mezzanines, pantries, or the space under the windowsill.
The air temperature should not be higher than 25 degrees. The optimal temperature range for storing mushrooms without a refrigerator is 15-18 degrees. It is important that the sun's rays do not fall on the product, as they contribute to the destruction of organic matter.

In a refrigerator
The best conditions for storing canned mushrooms are in the refrigerator or cellar. In this case, the optimal temperature range for preserving nutrients is 0-4 degrees. The shelf life of the blanks in this case depends on the type of lid:
- preservation under polyethylene covers – 6 months;
- under metal covers – 1 year;
- under glass covers – 2 years.
When metal lids come into contact with a solution of salt, sugar and vinegar, they begin to oxidize. If you are not sure that the tin lid reliably resists oxidative processes, do not store such a jar in the refrigerator for more than 3-4 months.
In the freezer
Since the marinade salt solution does not freeze, canned mushrooms can be stored in the freezer of a home refrigerator. Tubular mushroom organisms are better stored in this way, as opposed to lamellar ones, which, after thawing, can lose their elasticity and become too soft. The shelf life of mushrooms in the freezer is 2 years.
After opening the lid
After opening, preserved products under iron and other types of lids are stored in the refrigerator for no more than one day. To feed a small number of people, choose small jars so that the product can be consumed in 1-2 doses. For harvesting tasty forest creatures, containers with a volume of 0.7-1.0 liters are best suited.
Sealed storage: conditions and terms
GOST defines how long pickled mushrooms can be stored under an iron lid.
In glass jars under metal lids, pickled mushroom products can be stored for up to 1 year. Over a year, the metal oxidizes and the product deteriorates.
Shelf life under glass lids is 2 years, since glass is more resistant to the influence of salty and acidic environments.
Canned products must be transferred to cool conditions, a cellar, balcony, refrigerator, where there is no access to a large amount of light. Inspect rolled cans periodically to spot possible mold growth in time.
If you notice a small film , you need to drain the marinade completely , wash the mushrooms and repeat the canning process in new fresh brine. Unfortunately, after repeated cooking, products partially lose their taste and beneficial properties. Therefore, it is so important to follow the rules for storing home preserves and the heat treatment time during initial preparation.
Marinated mushrooms in the refrigerator
So, let’s find out how long pickled mushrooms can be stored in the refrigerator and other cool places:
- up to 10 degrees without hermetically sealing the cans - 7-9 months;
- at 4-6 degrees in glass jars with iron lids - 1 year;
- at temperatures up to 5 degrees in jars with hermetically sealed glass lids for up to 2 years.
At temperatures below −15−18 degrees, mushrooms can be stored for up to 3−4 years. But in this case, the taste and beneficial properties are lost.
Advice from gastroenterologists
- In case of poisoning, consult a doctor immediately! Immediately rinse the stomach and give the patient cold, lightly salted water, tea, and milk. Alcohol is strictly prohibited.
- Children under 6 years old should not be given any mushrooms, as they can be harmful to the body.
Happy mushroom harvest to you! Be careful and healthy!

Drain in a colander and place on a kitchen towel to dry from the liquid. After this, they can be cut into pieces, especially if they are large. Place in plastic bags or food containers and place in the freezer. Boiled butter will take up less space in the freezing chamber. You need to freeze them in small portions, since boletus does not like re-freezing - this causes them to lose their appearance, becoming loose and unaesthetic.
