If you've ever picked up two different cannabis strains and noticed one smells like citrus while the other smells like pine, gas, or fresh-cut grass — you've experienced terpenes in action.
Terpenes are one of the most important parts of the cannabis experience, but they're also one of the most overlooked. Most consumers focus on THC percentages when they shop, but seasoned cannabis enthusiasts (and the budtenders at Pepe) will tell you that terpenes often matter more. Here's a beginner-friendly explanation of what terpenes are, why they shape how a strain feels, and how to use this knowledge to shop smarter.
The Quick Answer
• Terpenes are aromatic compounds produced by many plants, including cannabis
• They're what give each strain its unique smell and flavour
• They also appear to influence how a strain feels — beyond just THC content
• Different cannabis strains have different terpene profiles, which is why two strains with similar THC levels can feel completely different
• Learning to recognize terpenes is one of the best ways to choose strains you'll actually enjoy
What Are Terpenes?
Terpenes are aromatic compounds produced by many plants — including cannabis, hops, lavender, citrus fruits, pine trees, and countless others. They're the molecules responsible for the distinctive smells of nature: the citrus scent of an orange peel, the pine of a Christmas tree, the lavender in a relaxing essential oil.
In cannabis, terpenes are produced in the same resin glands (trichomes) that produce cannabinoids like THC and CBD. They serve a biological purpose for the plant — protecting it from predators, attracting pollinators, and helping it survive different climates. But for consumers, they shape something else entirely: the aroma, flavour, and overall character of every strain.
There are more than 100 different terpenes identified in cannabis. Most strains contain a unique blend of 5 to 10 dominant terpenes, with the rest present in smaller amounts. The specific combination is called a terpene profile, and it's as unique to each strain as a fingerprint.
Why Do Terpenes Matter in Cannabis?
Terpenes do three things that matter to the cannabis consumer:
1. They define the flavour and aroma.
The reason one strain smells like lemons and another smells like diesel comes entirely down to terpenes. THC has almost no aroma on its own. Everything you smell and taste in cannabis is the work of terpenes.
2. They appear to influence the experience.
Researchers and growers increasingly believe that terpenes shape how a strain feels — not just how it smells. A strain dominant in earthy, musky terpenes tends to feel different from a strain dominant in bright, citrusy ones, even at similar THC levels.
3. They contribute to the entourage effect.
This is the theory that cannabinoids and terpenes work together synergistically — meaning the combination of compounds in whole-flower cannabis produces effects that are different from (and often more nuanced than) isolated THC alone. This is one reason many consumers prefer full-spectrum products like flower and live resin over highly refined options like distillate.
The Most Common Cannabis Terpenes
You don't need to memorize a chemistry textbook. Just getting familiar with these seven terpenes will dramatically improve how you shop for cannabis.
Myrcene
The most abundant terpene in modern cannabis. Earthy, musky, and slightly herbal — also found in mangoes, hops, lemongrass, and thyme. Myrcene-dominant strains are commonly associated with the classic, body-heavy character of indica-leaning hybrids.
Limonene
Bright, citrus, and zesty — also found in citrus peels and juniper. Limonene-dominant strains tend to feel more uplifting and bright, often described as energetic or mood-boosting. You'll find strong limonene in strains like our house cultivar Lemonatti and Peach Tree.
Pinene (Alpha- and Beta-)
Fresh pine forest, rosemary, sage, basil. Pinene is one of the most widespread terpenes in nature and gives certain strains a clean, sharp, almost menthol-like note. Often associated with focused, clear-headed experiences.
Linalool
Floral, soft, lavender-like. Linalool is the dominant aromatic in lavender essential oil and shows up in strains with a softer, calmer character. Less common as a dominant terpene but adds complexity when present.
Caryophyllene (Beta- and Trans-)
Spicy, peppery, slightly woody — also found in black pepper, cloves, and cinnamon. Caryophyllene is unique because it's the only terpene that also acts directly on the body's cannabinoid receptors. It appears in many strains across both indica and sativa categories, including Pepe's Lemonatti and Peach Tree.
Humulene
Earthy, hoppy, slightly woody — the same terpene that gives beer hops their character. Common in OG and Kush genetics, contributing to that classic, deep, full-bodied aroma.
Terpinolene
Floral, herbal, slightly piney with a hint of citrus. Terpinolene-dominant strains are less common but often described as some of the most uniquely flavourful on the market. Often found in sativa-leaning genetics like Jack Herer and Dutch Treat.
Why Terpenes Often Matter More Than THC%
One of the biggest misconceptions in cannabis is that higher THC = better experience. The reality is more nuanced. A 22% THC strain with a rich, complex terpene profile will often feel more satisfying than a 30% THC strain with little aromatic character.
Why? Because terpenes shape the quality of the experience, not just the intensity. A high-THC strain with low terpene content can feel one-dimensional or even harsh. A balanced strain with strong terpene expression can feel layered, flavourful, and genuinely enjoyable — even at lower potency.

How to Use Terpenes to Shop Smarter
Once you start paying attention to terpenes, you'll notice patterns in what you actually enjoy. Here's how to put that knowledge to work:
1. Pay attention to aroma. When you open a fresh container of cannabis, the smell tells you almost everything about the terpene profile. Citrus, pine, fuel, berry, earth, pepper — those are all terpene signatures.
2. Look at the cannabinoid and terpene panel. Many premium Canadian producers now list the top 3 to 5 terpenes on the package, often as a percentage. A terpene total of 2% or higher generally indicates strong terpene expression.
3. Track what you like. If you keep gravitating toward citrus-forward strains, you probably like limonene. If you keep loving heavy, earthy strains, myrcene is likely your friend. Use your favourites to find new strains with similar profiles.
4. Don't dismiss "lower THC" strains. Some of the most enjoyable cannabis experiences come from strains in the 15–22% THC range with exceptional terpene content. Don't let the number on the label overshadow the smell.
The Bottom Line
Terpenes are the part of cannabis that you smell, taste, and remember. They're also one of the most useful tools for choosing strains you'll actually enjoy. Pay attention to them, and your sessions get more satisfying, more personalized, and more interesting.
