What Highest Terpene Means
Terpene content in dried flower is reported as a percentage of total weight. Most samples test between 1% and 2% total terpenes. Flower marketed as high-terpene tests above 2%. A small number of batches reach 3% to 4%. Numbers above that are rare in flower and common in concentrates.
No single strain holds the record. The number depends on the cut, the grow, the harvest date, the dry and cure, and the lab that runs the test.
Strains That Test High
- GMO Cookies (GMO): caryophyllene, limonene, humulene.
- Super Lemon Haze: terpinolene, limonene, ocimene.
- Chemdog and Chem 91: caryophyllene, myrcene, limonene.
- Do-Si-Dos: limonene, caryophyllene, pinene.
- Jack Herer: terpinolene, pinene, caryophyllene.
- Gelato and Runtz: caryophyllene, limonene, linalool.
- Tangie and Tangerine Dream: myrcene, limonene, terpinolene.
- Blue Dream: myrcene, pinene, caryophyllene.
- OG Kush: myrcene, limonene, caryophyllene.
These are common profiles, not guarantees. A batch of GMO from one farm can test lower than a batch of Blue Dream from another.
Terpenes in CBD Hemp Flower
Hemp flower carries the same terpene classes. Hemp cultivars with strong profiles include Sour Space Candy, Elektra, Abacus, Cherry Wine, and Bubba Kush. Total terpene content in hemp flower is often lower than in high-THC flower. Lab reports show many hemp samples between 0.5% and 2%.
How Labs Measure Terpenes
Labs use gas chromatography with mass spectrometry (GC-MS) or flame ionization detection (GC-FID). The sample is heated, the volatile compounds separate, and each one is identified by retention time. Two labs can report different totals for the same flower. Sample size, grind, storage, and the calibration curve all change the number.
What to Read on a COA
- Total terpene percentage, not just the top three peaks.
- Individual terpene percentages.
- Batch or lot number that matches the package.
- Test date. Terpenes are volatile and fade in storage.
