Does Drying Method Really Affect Potency? Let's Look at the Data
18 replies · Strain Discussion
There's a lot of debate about whether freeze-drying vs. food dehydrator vs. fan-and-desiccant meaningfully affects psilocybin potency. I've seen claims that freeze-drying preserves significantly more alkaloids and I've also seen people dismiss it as overblown. Is there actual data on this, or are we mostly speculating?
The most relevant data: Oakland Hyphae Cup potency analyses compare different drying methods. Freeze-dried samples consistently test 10-20% higher in total tryptamines than heat-dried samples from the same batch. This is a real difference but smaller than advocates claim. The degradation mechanism is heat + oxidation — psilocin is more temperature-sensitive than psilocybin.
For practical purposes: if you're dehydrating at the correct temperature (95-115°F), the loss from heat-drying vs. freeze-drying is modest — probably under 15%. If you're drying at 140°F because you're impatient, you're losing significantly more. The temperature control matters more than the method for most home cultivators.
The bigger variable is storage after drying. Improperly stored mushrooms (high humidity, light exposure) lose alkaloids much faster than the 10-15% difference between drying methods. Desiccant in airtight jars in a dark location at room temperature preserves nearly as well as refrigeration. Humidity is the enemy.
