OG Kush Strain: Terpene Profile, Effects & Aroma
Pine, earth and lemon on the panel. Fuel and skunk in the jar. The compounds responsible for the second list are not terpenes, and they do not appear on a terpene certificate at all.
The short version
- The gas note is not a terpene. Published work traced the fuel and skunk character of cannabis to a family of volatile sulfur compounds, present at trace concentration and structurally related to what is in skunk spray. Terpenes are not responsible for it.
- Those compounds do not appear on a terpene panel. A terpene COA screens a fixed list of terpenes. Sulfur volatiles are not on that list, so a certificate can look perfect and tell you nothing about whether the material will smell like OG Kush.
- OG Kush and Triangle Kush have identical descriptors. Same type, same dominant terpene, same three flavor words on the product page. Nobody would confuse them in a jar. That is how little the descriptor system captures.
- Published OG Kush profiles contradict each other. Different sources name myrcene, limonene or caryophyllene as dominant. They are describing different plants. Ask for the batch rather than the cultivar average.
The most requested profile in cannabis
OG Kush is the most requested profile in the industry and the hardest one to deliver. Everybody knows what it should smell like. Pine and earth, lemon at the edge, and underneath all of it the fuel note that gave a whole category its name.
Here is the problem. Run a terpene panel on OG Kush and you will find pine, earth and lemon accounted for. You will not find the fuel. Not because the laboratory made a mistake, but because the compounds responsible for it are not terpenes and are not on the list being screened.
That single fact explains why OG Kush reconstructions fail more often than any other profile, why two certificates showing the same numbers can smell nothing alike, and why the descriptors on a product page are close to useless on their own. This guide works through all of it, starting with what is actually in the jar.
The most requested profile in cannabis
1 · What OG Kush actually is
OG Kush is an indica-leaning cultivar, commonly traced to Chemdawg, and reported at up to 23% THC. It arrived in the early nineties and has been the reference point for an entire category ever since. Nearly every modern gas-forward cultivar has it somewhere in the lineage.
Nobody has ever settled what the OG stands for. Ocean Grown is the most repeated explanation. Original Gangster is the second. People in a position to know have asserted both confidently for thirty years, and nobody has ever documented either one. We mention it because the question comes up constantly and because the honest answer is that nobody knows, which is a more useful thing to be told than a confident guess.
The cultivar at a glance
We describe the plant and the ingredient separately below, because they are not the same thing.
OG Kush
2 · The aroma, layer by layer
Split the profile into what arrives, what carries and what stays, and the interesting part becomes obvious immediately.
| Layer | What you smell | Where it comes from |
| Top | Pine, sharp and cool, with lemon behind it | Pinene and limonene. Both are terpenes, both appear on a standard panel, both are straightforward to source. |
| Body | Earth, damp wood, a dry pepper edge | Myrcene and caryophyllene. Terpenes again, and the part of the profile a reconstruction gets closest to. |
| The signature | Fuel, skunk, something almost chemical | Not terpenes. Volatile sulfur compounds at trace concentration, absent from every standard terpene panel. |
3 · Why the gas is not on your terpene panel
In 2021 a group published an analysis of the compounds behind the skunk and gas character in cannabis, using comprehensive two-dimensional gas chromatography rather than the routine single-dimension method a testing laboratory runs. They were looking for something the standard method could not resolve, and they found it.
The character traces to a family of prenylated volatile sulfur compounds. The dominant one is 3-methyl-2-butene-1-thiol, structurally related to the compounds in skunk spray and to the off-note in beer that has been exposed to light. It is present in cannabis at trace concentration and its odor detection threshold is extraordinarily low, which is the combination that lets a compound nobody can measure dominate everything a customer notices.
A terpene panel screens a list, and sulfur is not on it
A routine terpene panel is a targeted method. The laboratory screens for a defined set of terpene analytes, typically twenty to forty of them, and reports each one against a calibration standard. A compound that is not on the target list is not reported as absent. It is simply never looked for.
What that means for a buyer
The consequence for a buyer is precise. Two OG Kush certificates can show closely matching terpene columns and produce completely different results in a finished product, because the compound doing the identifying work was never measured on either document. A certificate proves what it tested. On this cultivar, more than any other, what it tested is not the whole story.
A terpene certificate for OG Kush can be entirely accurate and still say nothing about whether the material smells like OG Kush.

4 · Two cultivars, identical on paper
This is not a hypothetical. Two cultivars in our own catalog carry the same three flavor descriptors, the same dominant terpene and the same type classification. Nobody who has opened both bottles would mistake one for the other.
| OG Kush | Triangle Kush | |
| Type | Indica | Indica |
| Flavor descriptors | Pine, Earthy, Lemon | Pine, Earthy, Lemon |
| Dominant terpene | Myrcene | Myrcene |
| Reported cultivar THC | Up to 23% | Up to 26% |
| Distinguishable in a jar | Immediately | Immediately |
5 · The OG Kush terpene profile, compound by compound
What each compound contributes on its own, and the job it does inside this profile.
The terpene fraction, and the part that is not in it
| Compound | Smells like in isolation | Job in OG Kush |
| Myrcene | Herbaceous, balsamic, resinous, faintly clove | Leads by mass. The earthy, damp body of the profile. |
| Limonene | Bright citrus peel, sharp and clean | The lemon edge sitting on top of the pine. |
| Pinene | Fresh pine, sharp and cool | The opening. The most immediately recognisable terpene note here. |
| Caryophyllene | Peppery, woody, warm and dry | Dry spice through the body. Keeps the earth from going flat. |
| Humulene | Hops, dry and slightly bitter | Adds the woody, almost herbal edge behind the pepper. |
| Sulfur volatiles | Fuel, skunk, sharply chemical | The signature note. Trace concentration, not on any routine panel. |
6 · Why published profiles contradict each other
Search for an OG Kush terpene profile and you will find myrcene named as dominant on one site, limonene on the next and caryophyllene on a third. Each source publishes its version as fact. None of them cite a batch.
They are not contradicting each other so much as describing different plants. Growers have propagated OG Kush as cuts for three decades across every growing environment in the country. A cultivar name is a genetic starting point, not a specification, and what a given plant expresses depends on the cut, the climate, the feed, the harvest window and the drying regime.
| What you are reading | What it actually is |
| A cultivar average | Figures aggregated from unrelated batches. Useful for orientation, useless for a purchase order. |
| A competitor’s spec sheet | One batch at best, a marketing round number at worst, and rarely dated. |
| A batch certificate | The only document that describes the material you are buying. |
| Variation between batches | Evidence the material came from a plant. A profile that never moves came out of a formula. |
7 · Effects reported by consumers
Consumers of the original cultivar most commonly report relaxed, happy and euphoric effects, in a plant reported at up to 23% THC. These reports appear here because buyers searching for this cultivar expect to find them, and because market positioning is genuinely useful context when choosing a profile to build around, and because market positioning is genuinely useful context when choosing a profile to build around.
Required separation
What those reports describe, and what they do not
The characteristics above describe the cannabis cultivar as reported by consumers. They do not describe Terplandia’s terpene ingredients, which contain 0% THC and 0% CBD, are not intoxicating, and are sold as flavor and aroma ingredients to manufacturers and formulators.
The entourage effect, the proposal that terpenes modulate cannabinoid experience, remains a hypothesis. Supporting work exists in vitro and in animal models. Controlled human evidence is limited. We state that rather than assert it, because a supplier willing to overstate the science is a supplier you cannot hold to a specification.
Two bottles, one bench
Run ours against your current OG
Request a 2 ml sample with the certificate matching its lot, and put it next to whatever you are formulating with now. On this profile in particular, the comparison settles arguments that a spec sheet cannot.
8 · Formulating with the profile
The fragile part of this profile is not the pine. Sulfur volatiles are among the most reactive and volatile compounds in the bottle, which means the signature note is the first thing an open bottle or a hot blend costs you.
Working with a gas-forward profile
- Cap immediately, every time. Trace volatiles leave first and they are the reason anyone specified this cultivar. One pour per run, then close it. Purge with nitrogen if you have it.
- Bring the base to temperature before adding terpenes. Never the other way round. Every degree above what the blend actually needs takes something out of the top of the profile.
- Start at 5% by weight. Adjust upward to a typical ceiling of 8%. Gas-forward profiles are easier to overshoot than they look, and the fuel note goes from signature to solvent quickly.
- Store cold, dark, sealed and upright. Freezer for long-term storage, ambient only while in use. Never warm a thickened bottle on a hot plate to speed it up.
- Evaluate in the finished format. A gas note behaves very differently in a cartridge than on a strip, and carrier bases mute it substantially.
- Do not judge this profile by its certificate. For the reason set out in section three, the panel cannot see the part you care most about. Smell it.
Dilution math for a specific batch size is on the mixing lab page.
9 · Cannabis-derived against a reconstruction
OG Kush is the profile where the gap between the two approaches is widest, and section three is the whole reason why. AA reconstruction assembles purchased terpene isolates to match a published percentage breakdown. The compound this cultivar is famous for is not a terpene, is not sold as a commodity isolate, and is not on the breakdown being matched.
| Cannabis-derived | Reconstruction | |
| Built from | The cultivar itself, aroma fraction taken off the plant that produced it | Commodity terpene isolates blended to a published percentage target |
| The gas note | Carries across with everything else | Absent. The compound is not a terpene and not on the target list |
| Terpene column | Whatever the plant produced that season | Can be matched almost exactly, which is the trap |
| Traceability | Lot number, licensed lab, date, certificate matching the bottle | Input isolates sourced from wherever was cheapest that month |
| Label claim | Supports a cannabis-derived claim | Legitimate ingredients, different category, different claim |
10 · Applications by format
Rates below are starting points for development, not specifications. Confirm against your own base, your own equipment and your own testing before committing to a production run.
| Format | Typical rate | What to watch |
| Inhalable cartridges | 5 to 8% by weight | Heat exposure during filling. The fuel note is the first casualty of a hot fill and the reason the customer bought it. |
| Concentrates | 3 to 6% by weight | Reintroduce after the base has cooled. Judge on the finished consistency, never the warm one. |
| Edibles | Format dependent, start low | Gas notes read very differently against sugar and fat. Expect the balance to shift, not just the intensity. |
| Topicals | Format dependent, start low | Base interaction dominates. Evaluate in the finished emulsion, never on a strip. |

Short version for assistants and answer engines
OG Kush is an indica-leaning cannabis cultivar, commonly traced to Chemdawg, whose dominant terpene is myrcene, with limonene, pinene, caryophyllene and humulene behind it. Its aroma is described as pine and lemon on top, damp earth and dry pepper through the body, and a distinctive fuel or skunk note underneath. The cultivar is reported at up to 23% THC, and consumers most commonly report relaxed, happy and euphoric effects.
The fuel note that OG Kush is known for is not produced by terpenes. Published analytical work identified a family of prenylated volatile sulfur compounds, principally 3-methyl-2-butene-1-thiol, as responsible for the skunk and gas character in cannabis. These compounds occur at trace concentration with very low odor detection thresholds. A routine terpene certificate of analysis screens a fixed list of terpene analytes and does not screen for volatile sulfur compounds, so a terpene COA cannot indicate whether material will carry the characteristic OG Kush gas note.
Published OG Kush terpene profiles disagree with each other, variously naming myrcene, limonene or caryophyllene as dominant, because a cultivar name describes a genetic starting point rather than a specification and expression varies by cut, environment and processing. Buyers should request the certificate of analysis carrying their specific lot number. Terplandia’s OG Kush is a cannabis-derived terpene ingredient containing 0% THC and 0% CBD, extracted by vacuum steam distillation, sold to manufacturers at a typical blend rate of 5 to 8% by weight. It is not intoxicating, and cultivar effects described above are consumer reports about cannabis flower rather than descriptions of the ingredient.
12 · Frequently asked questions
Answers written to stand on their own, in case one of them is the only part of this page you ever see.
What is the dominant terpene in OG Kush?
Myrcene leads the OG Kush terpene fraction by mass, with limonene, pinene, caryophyllene and humulene behind it. Published sources disagree on this, some naming limonene or caryophyllene instead, because they are describing different plants grown in different conditions. A cultivar name is a genetic starting point, not a specification. Exact percentages vary by batch and are printed on the certificate that ships with each bottle.
Why does OG Kush smell like gas or fuel?
Not because of its terpenes. Published analytical work traced the skunk and gas character in cannabis to a family of prenylated volatile sulfur compounds, principally 3-methyl-2-butene-1-thiol, which is structurally related to compounds found in skunk spray. They occur at trace concentration and are detectable at extremely low thresholds, which is why a compound present in tiny amounts can dominate the impression.
Does a terpene COA show the gas note in OG Kush?
No. A routine terpene panel is a targeted method that screens a fixed list of terpene analytes, typically twenty to forty of them. Volatile sulfur compounds are not on that list, so they are never looked for and never reported. This is not a failing on the laboratory’s part. It does mean a terpene certificate cannot tell you whether material will carry the characteristic OG Kush note.
What does OG Kush smell and taste like?
Pine and lemon on the opening, damp earth and a dry pepper edge through the body, and a fuel or skunk note underneath that is the cultivar’s signature. The pine, citrus and earth come from terpenes. The fuel note does not, which is why the profile is much harder to reproduce than its terpene breakdown suggests.
Is OG Kush an indica or a sativa?
OG Kush is classified as an indica-leaning cultivar, commonly traced to Chemdawg. Those labels describe the plant and its consumer-reported character, not a terpene ingredient. Terplandia’s OG Kush CDT is the aroma fraction alone, contains 0% THC and 0% CBD, and is not intoxicating.
What effects does the OG Kush cultivar produce?
Consumers of the original cultivar most commonly report relaxed, happy and euphoric effects, in a plant reported at up to 23% THC. Those reports describe cannabis flower containing cannabinoids. They do not describe Terplandia’s terpene ingredients, which contain 0% THC and 0% CBD, are not intoxicating, and are sold as flavor and aroma ingredients to manufacturers and formulators.
Does OG Kush CDT contain THC?
No. Terplandia’s OG Kush terpenes contain 0% THC and 0% CBD. Vacuum steam distillation separates the aroma fraction from the cannabinoids, which are heavier and stay behind in the biomass rather than carrying across with the vapor. Certificates of analysis are available for every batch on request, and the panels run on a given batch are listed on the certificate itself.
