Myrcene is the most commonly occurring terpene in commercial cannabis. This terpene has an earthy, musky smell balanced out by a fruity aroma reminiscent of red grapes. This terpene usually imparts that distinctive but hard to classify “funky” smell of some strains. It is also naturally occurring in fruits and herbs such as mangoes, thyme, and lemongrass. It is present in hops and is responsible for the balsam- like fragrance in many beers.
Limonene is characterized by a distinctly fruity and citrusy profile. This fresh-smelling terpene can be found in citrus fruit, cleaning products and cosmetics. Although these naturally occurring oils are easy to detect in flower, you should not assume that just because a particular strain smells like lemon or citrus that it definitely contains higher concentrations of limonene. The only sure-fire way to ensure you are consuming a strain with an abundance of limonene is through lab testing.
Caryophyllene is a special terpene. This gem packs a spicy punch very much like that of fresh black pepper, making it easily recognizable when present in flower. This terpene is also present in clove and cinnamon and these distinct smells are often found in strains with a higher abundance of caryophyllene. It is not uncommon for citrusy, musky scents to be found in these strains as well.
