Terpinolene
Terpinolene is less common as a dominant terpene, but it defines strains like Jack Herer, Durban Poison and Ghost Train Haze. Its complex fresh-floral smell is often linked with lively, creative sativas.
What it smells like
Fresh, floral, herbal, a little piney. You'll also find it in Lilacs, apples, nutmeg, tea tree.
Boiling point
About 366°F / 186°C. If you use a temperature-controlled vaporizer, terpenes vaporize at different points, which is one reason the same flower can taste different at different settings.
A note on terpenes and effects
Terpene research in cannabis is still young. Aromas are real; claims about specific effects are generalizations. The best guide is your own experience with a strain, starting low.
