How to freeze psilocybin mushrooms properly

Can I freeze fresh magic mushrooms?

It is common question we get and the short answer is YES. Freezing has been widely used as an alternative to drying for edibles as well.

Proper freezing allows to save alkaloids in mushrooms better. This is the main advantage of such storage method.

However this method has disadvantages for amateur, because you can spoil your harvest with improper freezing.

How freezing can spoil your magic mushrooms

However, we would recommend drying them a little. Why?

Water, which makes up to 90% of the mass of the fungus, crystallizes when freezing. Thus, frozen mushrooms will retain their shape with ice crystals instead of their own cellular structure.

Since ice expands during crystallization, cells are destroyed and loose alkaloids.

Frozen mushrooms after defrosting can turn into a shapeless mass and have zero effect

How to freeze fresh magic mushrooms and save potency

Remember, the faster and deeper mushrooms are frozen, the less and smaller ice crystals are formed in them. Thus, the structure of mushroom cells is preserved better.

🔵 Don't wash your shrooms!

🔵 Pack them in airtight bags, plastic sealed containers or airtight zip bags

🔵 Put them in the freezer at 0°F (-18°C) and lower temperature. Don't freeze mushrooms if you have higher temperatures! If we freeze fresh shrooms at 14-23°F (-5..-10°C) then we can move them to bin from the start, they will loose potency for sure

❄️ Ideal is «quick dry freeze» mode at -4..-22°F (-20°..- 30°C). This temperatures work good for freezing mushrooms

❗️If you are not sure about freezing conditions don't use this method, just dry mushrooms for storage

❗️Defrost mushrooms before consumption only!❌ Psilocybin mushrooms shouldn't be frozen again after defrosting. This is the main disadvantage of this storage method. Since any sudden shutdowns of the refrigerator can ruin the frozen crop. Therefore, drying mushrooms is still preferable method.

💡 In case of using liquid N2 for freezing we don't have water crystallization, don't ruin cell walls and don't have oxidation. However it's not an easy way to implement at home

Freeze-drying method

Freeze-drying is used in industrial scale.

Freeze-drying (aka lyophilisation or cryodesiccation) — is a low temperature dehydration process that involves freezing the product, lowering pressure, then removing the ice by sublimation.

In contrast to dehydration by most conventional methods that evaporate water using heat. This is the best and most expensive method that totally preserves mushroom structure, shape and color.

Can I freeze dried magic mushrooms?

Yes, it's safe for mushrooms, because they already dehydrated. For dry mushrooms freezing slowing chemical kinetics of reaction and preserves the mushroom tissue better.

However you can store dry mushrooms at refrigerator or room temperature in dark place and airtight bags/jars.

Yes, you can freeze magic mushroom chocolate (chocolate with dried mushroom powder). Make sense to do this if you want to prolong chocolate expiration date. Such magic chocolate don't lose potency in freezer and can be stored for 1-2 years.
