The Terpene Glossary

A field guide to what you're smelling.

Terpenes are aromatic compounds — the reason cannabis smells like anything at all. They're not unique to cannabis: the limonene in your flower is the same molecule in a lemon peel, and the pinene is the same pinene rising off a pine forest after rain. When you smell a jar, you're reading its terpene profile with the most sophisticated instrument ever built: your nose.

How to use this glossary. Each entry gives you the aroma, where else in nature you'll meet it, and what its presence (or dominance) tends to signal in cannabis. Dominant means it showed up in the highest concentration on a lab report — it's the lead note, not the whole chord. A cultivar typically expresses dozens of terpenes; most labels list only the top three.

The honest part. Terpene profiles vary by batch — same cultivar, different harvest, different profile. And while folk wisdom attaches all kinds of promises to individual terpenes, this library doesn't predict effects from chemistry. Aromas are data. Everything else is a question.

Myrcene mer-SEEN

Aroma: Earthy, musky, herbal — damp soil, cloves, ripe mango skin.

Also found in: Mango, lemongrass, thyme, hops, bay leaf.

In cannabis: The most common terpene in commercial flower, and the dominant one in a huge share of modern cultivars. When myrcene leads a profile, the nose tends toward earth and musk rather than brightness. If a jar smells “danky” in that classic way, myrcene is usually doing heavy lifting.

Limonene lim-oh-NEEN

Aroma: Citrus — lemon zest, orange rind, sharp and bright.

Also found in: Citrus peels, juniper, peppermint.

In cannabis: The signature of citrus-forward cultivars. A limonene-dominant profile reads as uplifting in aroma — not a prediction, just the nose. Common in Haze lines, Wedding Cake descendants, and anything with “Lemon,” “Tangie,” or “Mimosa” in the name (though names, as always, are a starting point, not a promise).

Caryophyllene carry-oh-FILL-een

Aroma: Peppery, spicy, woody — cracked black pepper, cloves, cinnamon bark.

Also found in: Black pepper, cloves, cinnamon, oregano, basil.

In cannabis: The only major cannabis terpene that also binds to cannabinoid receptors (CB2) — a genuine chemistry footnote that makes it a favorite of researchers. Dominant in Kush lines, Cookies descendants, and Gelato. When a jar smells like a spice cabinet, this is usually why.

Pinene (α-Pinene) pie-NEEN

Aroma: Pine, conifer, rosemary — a walk through a pine forest.

Also found in: Pine needles, rosemary, sage, eucalyptus.

In cannabis: The backbone of the classic “piney” nose — Jack Herer, Blue Dream, OG Kush all carry it prominently. It’s also one of the most volatile terpenes, meaning it evaporates fast: a jar that smells flat where it should smell like a forest may simply be old.

Terpinolene ter-PIN-oh-leen

Aroma: Complex and hard to pin down — floral, citrus, herbal, and piney all at once, with a fresh, almost “clean” quality.

Also found in: Lilac, nutmeg, cumin, tea tree, apples.

In cannabis: The signature terpene of classic Hazes and many “Dutch” sativas — Super Silver Haze, Jack Herer, Durban Poison. Terpinolene-dominant profiles are less common in modern dessert cultivars, so when you smell that old-school haze complexity, you’re smelling a rarer chemotype.

Linalool lin-ah-LOOL

Aroma: Lavender, floral, slightly sweet and powdery.

Also found in: Lavender, basil, rosewood, coriander.

In cannabis: Rarely dominant, often a supporting note that rounds out a profile with floral softness. Shows up in Do-Si-Dos, some purples, and lavender-leaning phenotypes. Its presence is a good reminder that the supporting terpenes shape character as much as the dominant one.

Humulene HYOO-myoo-leen

Aroma: Woody, earthy, hoppy — dry woods, dried herbs.

Also found in: Hops (hence the name), coriander, clove, ginseng.

In cannabis: A frequent second or third terpene in Kush and Cookies lines, where it adds woody depth behind caryophyllene’s spice. Sour Diesel and Headband carry it notably. Structurally similar to caryophyllene — the two often travel together.

Ocimene OH-sih-meen

Aroma: Sweet, herbal, tropical — basil with a candy edge.

Also found in: Basil, mint, orchids, mangoes.

In cannabis: A lighter, brighter supporting terpene common in hazes and sativa-leaning cultivars (Strawberry Cough, Green Crack lines). Highly volatile — one of the first aromas to fade in an aging jar, so its presence signals freshness.

Bisabolol bis-AH-boh-lol

Aroma: Floral, sweet, honeyed — chamomile tea, light honey.

Also found in: Chamomile (its namesake source), candeia tree.

In cannabis: A minor terpene that shows up in the supporting cast of dessert and candy cultivars — Gelato, Wedding Cake, some Cookies crosses. When a jar smells sweet in a soft, floral way rather than a sharp citrus way, bisabolol may be contributing.

Valencene vah-len-SEEN

Aroma: Sweet orange, citrus peel with a woody base.

Also found in: Valencia oranges (its namesake).

In cannabis: A citrus terpene distinct from limonene — rounder, sweeter, less sharp. Appears in Tangie lines and orange-forward cultivars. Its presence alongside limonene is what separates “orange juice” citrus from “lemon cleaner” citrus. Your nose knows the difference even if the label doesn’t explain it.

Geraniol jer-AY-nee-ol

Aroma: Rose, geranium, sweet floral with a citrus lift.

Also found in: Roses, geraniums, citronella, lemongrass.

In cannabis: A minor floral terpene that contributes the “rose” note in some purples and floral phenotypes. Rarely dominant; when it shows up in a report, it usually marks a genuinely floral cultivar rather than a fruity one mislabeled as floral.

Terpineol (α-Terpineol) ter-PIN-ee-ol

Aroma: Lilac, pine blossom, floral with an earthy base — like flowers growing in a forest.

Also found in: Lilac, pine oil, eucalyptus.

In cannabis: Shows up in Jack Herer phenotypes, White Widow lines, and some hazes. Contributes a distinctive floral-pine character that’s neither purely floral (like linalool) nor purely conifer (like pinene). A good example of why the supporting cast matters.

Eucalyptol yoo-kah-LIP-tol

Aroma: Eucalyptus, minty, cool — camphor-adjacent freshness.

Also found in: Eucalyptus, bay laurel, tea tree, rosemary.

In cannabis: A minor terpene that adds a cooling, almost menthol lift. Present in Headband, Girl Scout Cookies lines, and some hazes. When a jar smells “cool” or “fresh” in a way you can’t quite place, eucalyptol is a usual suspect.

Camphene KAM-feen

Aroma: Camphor, fir, damp wood — sharp, resinous, medicinal in the old apothecary sense.

Also found in: Camphor laurel, fir oil, citronella.

In cannabis: A minor terpene in Ghost OG, Strawberry Banana, and Mendocino Purps lines. Contributes resinous sharpness. Rarely discussed, which is exactly why it’s in this glossary — the minor terpenes are where real connoisseurship lives.

Sabinene SAH-bih-neen

Aroma: Peppery, woody, citrus-rind — like black pepper grated over an orange.

Also found in: Black pepper, juniper, spruce, holm oak.

In cannabis: A minor terpene notable in Super Silver Haze and some sativa lines. Adds a spicy-citrus edge distinct from both limonene (pure citrus) and caryophyllene (pure spice). Another supporting-cast member that shapes the nose more than its concentration suggests.

Nerolidol neh-ROH-lih-dol

Aroma: Floral, woody, fresh bark — rosewood, apple blossom, a walk through an orchard.

Also found in: Jasmine, neroli oil, ginger, tea tree.

In cannabis: Present in Skywalker OG, Jack Herer, and Island Sweet Skunk lines. One of the more distinctive floral-woody terpenes — when a profile smells floral but not like lavender, nerolidol is worth looking for on the report.

Reading a profile, not just a list

A lab report lists terpenes by concentration, highest first. Here's how to read it like a curious person instead of a spreadsheet:

  1. Start with the top three. They define the dominant character — the first impression your nose gets.
  2. Look at the ratios, not just the ranks. A profile that's 2.1% myrcene and 0.3% limonene is a myrcene story. One that's 1.2% myrcene and 1.0% limonene is a duet.
  3. Check the total. Total terpene content (often 1–3% of flower weight) tells you about overall aromatic intensity — and, indirectly, freshness and cure quality.
  4. Compare batch to reputation. If the library's reference entry says a cultivar is typically caryophyllene-dominant and your batch leads with terpinolene, you've found batch variance in the wild. That's not a flaw in the data — that's the data working.

These are recorded reference profiles — what's been documented about these compounds and where they appear — not measurements of any batch, and not predictions of effects. For what's in your jar, read the batch's own report.
