Terpenes are volatile – they react sensitively to heat, light, air and time. Proper drying, storage and consumption preserves the terpene profile and improves the experience.
The terpene profile measured in a cannabis lab analysis corresponds to the profile of the freshly harvested plant. But between harvest and consumption, many processes can change or destroy terpenes: drying, curing, storage and finally heating during consumption.
## Terpene Boiling Points
Terpenes are relatively volatile compounds – they evaporate at moderate temperatures. Key boiling points: myrcene 168 °C, limonene 176 °C, alpha-pinene 155 °C, caryophyllene 130 °C, linalool 198 °C. This explains why vaporiser temperature affects the terpene profile.
## Drying: The Critical First Step After Harvest
Too fast drying (above 35 °C): Monoterpenes (myrcene, limonene, pinene) evaporate at high temperature, leaving odourless cannabis.
Optimal drying: Slow, at 15–21 °C and 45–55% RH, over 7–14 days. Dark room with light air circulation.
## Curing: Developing and Stabilising Terpenes
Curing in airtight glass jars at 60–65% RH for 4–8 weeks: chlorophyll breaks down, sugars degrade, terpenes "round out". Burp jars daily in the first 2 weeks.
## Storage: Long-Term Terpene Preservation
UV light destroys terpenes photochemically. Oxygen causes oxidation. Store cool (15–20 °C), dark, airtight with humidity packs at 59–63% RH. Good terpene profile maintained for 6–12 months.
## Consuming: Temperature Controls the Terpene Experience
Start vaporising at low temperatures (160–180 °C) for the full terpene spectrum, then gradually increase. The first draws deliver light, aromatic vapour with maximum terpene content.
