Ocimene Boiling Point Explained With Real Vaping Temperatures That Work
Discover why ocimene's boiling point shows as both 150°F and 350°F online. Learn the real vaping temperatures that preserve this citrus terpene and how storage affects
Written by Lorien Strydom
You've seen conflicting numbers: some sources say ocimene's boiling point is 150°F, others claim 350°F.
Both are actually correct depending on pressure conditions.
At standard atmospheric pressure, beta-ocimene boils at 176-178°C (349-352°F). Under reduced pressure conditions used in processing, it boils at 65-66°C (149-151°F) at 13 mmHg.
What matters for you is that ocimene is one of the most volatile terpenes in cannabis, requiring careful temperature control from harvest through consumption.
We'll show you the real vaping temperatures that preserve ocimene's bright citrus-herbal character, explain why storage conditions matter more than you think, and help you read COAs in a way that sets realistic expectations.

Why You See Two Different Ocimene Boiling Points Online
The confusion starts with pressure. Beta-ocimene boils at 176-178°C (349-352°F) at standard atmospheric pressure, which is what you experience in everyday conditions.
Alpha-ocimene boils slightly lower at 169-171°C (336-340°F), while (3E)-beta-ocimene sits at 174-175°C (345-347°F). These differences matter if you're comparing specific isomers, though beta-ocimene is what you'll encounter most in cannabis discussions.
The 150°F figure comes from reduced pressure extraction: at 13 mmHg pressure, ocimene boils at 65-66°C (149-151°F). At 70 mmHg, it reaches approximately 100°C (212°F).
Beta-ocimene gets searched more frequently because it's the most common isomer in cannabis strains.
The isomers differ by double bond positions in their molecular structure, but beta-ocimene dominates terpene profiles in most varieties.
Here's what this means practically: the 350°F range matters for consumers vaping or smoking, while the 150°F range matters for processors extracting terpenes without destroying them.
Ocimene's low evaporation point under certain conditions makes it one of the most fragile cannabis terpenes you'll encounter.
The Vaping Temperatures That Actually Preserve Ocimene
Set your device around 280°F (138°C) to capture ocimene while activating other compounds. This temperature preserves the volatile monoterpenes that give cannabis its bright, citrus character.
Default vape settings often run 350-400°F, which far exceeds what ocimene needs.
At these temperatures, ocimene vaporizes and oxidizes before you inhale it, leaving only heavier terpenes and cannabinoids.
Combustion from smoking runs 400-800°F and completely destroys ocimene along with other volatile terpenes. You'll only taste what survives these extreme temperatures—primarily sesquiterpenes and cannabinoids.
Visible vapor clouds don't equal terpene preservation. Lower temperatures mean less visible vapor but significantly better flavor and a fuller spectrum of effects.
We recommend starting at 280°F and increasing gradually if needed.
Our vape collection includes options with temperature control for this exact reason.
This approach aligns with how we think about terpene preservation across all our products.
Temperature matters from cultivation through consumption, and understanding the boiling points helps you make informed choices.

Device Considerations
Many disposable vapes run at fixed temperatures above 350°F. If you're serious about tasting ocimene, look for devices with adjustable temperature settings.
Remember that even with perfect vaping temperatures, terpenes begin degrading the moment they're exposed to heat and air. Start with small amounts and consume fresh product whenever possible.
How Heat and Air Destroy Ocimene Before You Consume It
Ocimene degrades rapidly above 80°F (27°C) and oxidizes when exposed to air, forming yellow resin compounds. This degradation happens whether you're aware of it or not.
Delivery vehicles and porches can exceed 150°F in summer, especially in southern states.
Cannabis sitting in these conditions for even a few hours experiences permanent terpene profile changes.
Cool, dark, airtight storage is mandatory for preserving ocimene. Store products below 80°F in containers that minimize air exposure.
We work with small-batch cultivation partners who package cannabis close to harvest time. Recent packaging dates give ocimene the best chance of reaching you intact, though we can't control every shipping condition once products leave our facility.
This is chemistry affecting all cannabis products, not a flaw in any particular brand.
Setting realistic expectations about terpene stability helps you understand what you're actually experiencing versus what was present at testing time.
Shipping Reality Check
Summer shipping presents unique challenges. Even with careful packaging, prolonged exposure to temperatures above ocimene's volatility threshold will alter what you receive.
Consider ordering during cooler months if you live in hot climates and care deeply about terpene preservation. We ship year-round, but temperature awareness helps you time purchases for optimal freshness.
Reading COAs When Terpenes Change Over Time
Here's a practical heuristic: if the top three terpenes total less than 2%, the product often feels generic regardless of THC percentage. Terpenes in meaningful concentrations drive the diversity of cannabis effects.
Our Certificates of Analysis represent terpene content at testing time, not consumption time.
This distinction matters more with volatile terpenes like ocimene than with stable cannabinoids like THC.
Recent packaging dates matter as much as the numbers themselves. A product tested six months ago with high ocimene content may have significantly less today, especially if stored improperly.
We offer a 90-day money-back guarantee because we're confident in our quality control processes.
However, this guarantee doesn't override chemistry—terpenes degrade naturally regardless of initial quality.
What to Look for on a COA
Focus on the top three terpenes and their combined percentage.
Products above 2% total terpenes generally deliver more distinct experiences than those below this threshold.
Compare the test date to the packaging date. The closer these dates are, the more likely the terpene profile reflects what was actually packaged.
Remember that COAs show what was present under laboratory conditions.
Real-world storage and shipping conditions introduce variables that testing can't predict.
What Ocimene Is and Why It Smells Citrusy
Ocimene (C₁₀H₁₆) is a colorless liquid at room temperature with a density of approximately 0.800 g/cm³. Its melting point sits around -50°C (-122°F), while its flash point reaches 56°C (133°F).
It's chemically unstable in air, similar to myrcene and other volatile monoterpenes. This instability is why proper storage matters so much for preservation.
Fresh ocimene delivers warm-herbaceous, citrus, tropical, and green notes with woody and floral hints. These aromatic qualities signal that the terpene profile remains largely intact.
Weak or generic smell indicates degradation. If cannabis that should be bright and citrusy smells flat, it's likely lost significant ocimene content through oxidation or volatilization.
Ocimene appears naturally in mint, parsley, mangoes, lavender, and orchids.
This wide distribution in nature speaks to its appeal as an aromatic compound across plant species.
We hand-select strains based on terpene profiles, looking for products where ocimene appears in meaningful concentrations alongside complementary terpenes.
Our Focused category features products where ocimene typically plays a significant role in the overall effect.
Why Concentrates Taste Different From Flower
Reduced-pressure distillation at 65-66°C and 13 mmHg protects ocimene during extraction by keeping temperatures well below its standard-pressure boiling point. This is why you see that 150°F figure in processing contexts.
Even with careful processing, concentrates lose volatile monoterpenes including ocimene.
The high surface area exposure during extraction and handling creates opportunities for oxidation and volatilization.
Cannabis-derived terpenes (CDTs) and botanical-derived terpenes (BDTs) are molecularly identical.
An ocimene molecule from cannabis is chemically indistinguishable from one extracted from mango or lavender.
We don't fortify terpenes post-extraction, relying instead on naturally occurring profiles. This means our concentrates reflect what survived the extraction process rather than an artificially enhanced profile.
Expect concentrates to have different terpene ratios than flower even with excellent source material. This isn't a quality issue—it's an inherent limitation of processing volatile compounds.
Understanding CDT vs BDT
The debate around cannabis-derived versus botanical-derived terpenes misses a key point: chemistry doesn't care about the source. What matters is the final blend and how it's been handled from extraction through consumption.
We prioritize naturally occurring terpene profiles in our products.
Check out our concentrates to see how different processing methods affect the final terpene profile.
Finding Ocimene-Forward Products Without a Chemistry Degree
Look for three things: recent packaging dates, total terpene percentages above 2%, and bright citrus-herbal aroma when you open the container. These indicators work across all product types.
Ocimene appears more frequently in sativa-leaning strains, though exceptions exist.
If you're looking for that energizing, clear-headed experience, start with sativa-dominant options.
Our Focused products serve as a shortcut for finding energizing, ocimene-forward profiles without needing to understand the chemistry. We've done the lab work and selection for you.
Clementine and Jack Herer commonly feature ocimene in their terpene profiles. These strain names can guide you toward similar products if you've enjoyed them before.
Quick Selection Criteria
Check the packaging date first. Products packaged within the last 30-60 days have the best chance of maintaining their original terpene profile.
Smell matters more than you think. Fresh, bright citrus aromas indicate intact ocimene, while flat or generic smells suggest degradation regardless of what the COA showed months ago.
Browse our Social collection for products where terpene profiles support engaging, conversational experiences. Many social products feature ocimene alongside other uplifting terpenes.
What to Do Next
You now understand why both 150°F and 350°F appear as ocimene's boiling point—pressure makes all the difference. Standard atmospheric conditions give you the 350°F range, while reduced pressure extraction operates around 150°F.
Start vaping around 280°F to preserve ocimene and other volatile terpenes. Your device's default settings likely run too hot for optimal terpene preservation.
Store cannabis below 80°F in airtight containers away from light. This simple step preserves more of what you paid for than any other post-purchase action.
View COAs as testing snapshots rather than consumption guarantees. Recent packaging dates matter as much as high terpene percentages in predicting what you'll actually experience.
Check our Certificates of Analysis to see detailed terpene profiles for specific products. Compare total terpene percentages and look for products above the 2% threshold for more distinct effects.
Try a 280°F vaping session with one of our temperature-controlled vapes to taste the difference proper preservation makes. You'll notice brighter citrus notes and a fuller spectrum of effects when terpenes survive intact.
Pay attention to packaging dates when shopping through any of our mood-based categories.
Fresher product means more of the terpene profile you're selecting for remains present at consumption time.
You can now preserve and experience the ocimene you're paying for, whether you're evaluating our products or any cannabis purchase.
Temperature awareness, proper storage, and realistic expectations about COA timing give you the tools to get the most from every purchase.
