Terpenes and effect profile
What role terpenes play for aroma and product profile and how to cleanly separate marketing claims from data.
Analysis
GC-MS for profiling
Risk
Terpene loss from heat/oxidation
Use case
Product differentiation
Key points
- Terpenes complement potency data, but don't replace it.
- Sampling and storage massively affect terpene results.
- Effect claims need a clear evidence level and context.
What terpenes actually do
Terpenes shape the aroma of your harvest and influence how the product is perceived.
They don't replace lab values for cannabinoids — but they explain why two batches with the same THC values act differently.
Why this directly affects your quality
Terpenes are volatile: heat, air, and light break them down — poor storage destroys the profile.
If you understand terpene loss, you can concretely improve harvest, curing, and storage.
Relevant in SecretLeaf when
you want to compare batches and don't know why aroma differs
your curing or your storage changes the profile and you don't know why
you want to make sense of lab values and don't know which terpene figure is reliable
What you should specifically do
Checklist
- Dry and store harvest at < 22°C — every degree more measurably accelerates terpene loss
- Seal glass containers airtight — oxygen contact is the single biggest factor for profile change
- Only compare COA terpene figures when the same method and sampling time are documented
Frequently asked questions
Do I lose terpenes during drying and storage?
Can I compare terpene profiles between batches?
