Peel an orange, crush a sprig of rosemary, walk through a pine forest, open a fresh jar of flower. The smell that reaches you each time comes from terpenes, the aromatic compounds that give plants their scent and flavor. They are also a big reason two products with the same THC percentage can smell, taste, and feel different.
Terpenes 101: Aroma, Flavor & Effects is a free, self-paced course that gives you a working command of terpenes in about 45 minutes, from the science to the sales floor.
What you'll learn
Five sections with narration, flashcards, cited sources, and a seven-question quiz at the end.
Section 1, Terpenes 101, defines terpenes as a class of more than 30,000 aromatic compounds, shows where you already meet them every day (citrus peel, lavender, pine, rosemary, black pepper), explains what they do for the plant, and clears up the difference between terpenes and terpenoids.
Section 2, Terpenes in Cannabis, covers why each cultivar carries its own terpene fingerprint, then profiles the six terpenes you will see most often: myrcene, limonene, beta-caryophyllene, pinene, linalool, and humulene. You'll also learn typical terpene levels in flower and why freshness and storage change what ends up in the jar.
Section 3, Terpenes and Effects, introduces the entourage effect and how terpenes may work alongside cannabinoids like THC and CBD. It walks through what early research suggests for individual terpenes, is clear that most of that evidence is still preclinical, and explains why the same profile can land differently from one person to the next.
Section 4, Terpenes in Products and Industries, follows terpenes out of the flower jar: reintroduced terpenes in extracts and edibles, terpene blends, hemp and THC beverages, the overlap with brewing (hops and cannabis share myrcene and humulene), and wellness products from essential oils to topicals. It closes on botanical versus cannabis-derived terpenes and why sourcing and testing matter.
Section 5, Communicating Terpene Knowledge, turns it into a sales floor skill: why THC percentage is only part of the picture, how to describe a terpene by a scent the customer already knows, how to start from the experience they want, how to read the terpene panel on a label or lab report, and what to tell them about storage.
Who this is for
Budtenders and dispensary teams who want to recommend by aroma and experience as well as by THC percentage. Brand reps, hemp and THC beverage makers, and wellness retailers who need to explain what a terpene profile means on a label.
And the terpene-curious: anyone who has wondered why lavender, lemon peel, and black pepper smell the way they do.
What you walk away with
A clear definition of terpenes and how they differ from terpenoids. The six terpenes that show up most in cannabis and the everyday scents that help you remember each one. An honest read on what the research supports so far. A picture of how terpenes are used in extracts, beverages, beer, and wellness products. And a simple way to talk about all of it with a customer: start with the experience they want, then let aroma and the terpene panel guide the recommendation.
