Names create expectations; molecules create aromas
Amnesia Haze, Northern Lights, Cheese, Super Lemon Haze and Critical Mass are recognisable names in cannabis culture. Some names evoke a smell directly: Cheese suggests a savoury note, while Super Lemon Haze suggests citrus. The smell itself comes from a mixture of volatile molecules released by the material. Terpenes are part of that mixture, but recent research shows that compounds present in much smaller amounts can make an important contribution to the differences people notice.
Why a cheese-like note can emerge
A 2024 ACS Omega study examined five closely related cannabis phenotypes and found distinctive aromas despite broadly similar dominant terpene profiles. The researchers identified octanoic and decanoic acids, implicating these fatty acids in cheese-like aromas. They also reported a sulfur-containing compound, 3-mercaptohexyl hexanoate, among the minor volatiles associated with aroma differences. A prominent sensory note can therefore arise from chemistry that a short list of the most abundant terpenes overlooks. The study did not test every product sold under the name Cheese.
Amnesia Haze in a chemical comparison
Another 2024 study compared leaf and flower extracts from Amnesia Haze and Royal Dutch Cheese. Using computational metabolomics, the researchers mapped chemical families beyond cannabinoids, including flavonoids and phospholipids. Amnesia Haze showed greater prominence of flavonoids in the analysed profiles, while Royal Dutch Cheese showed more lipid-like molecules. The tissues also differed: phenylpropanoid compounds were more abundant in leaves than flowers. The work demonstrates that a plant’s chemistry includes much more than its THC or CBD content.

What the five labels leave open
Northern Lights and Critical Mass add further names to this vocabulary, but a name alone is not a measured chemical specification. Aroma, cannabinoid content and the rest of the plant’s metabolic profile describe different properties. The two studies explain why a citrus or cheese association cannot identify the entire mixture, and why closely related plants can still smell different.
