Beyond potency: giving cannabis aroma a shared vocabulary

The study in focus

A 2025 PLOS ONE paper developed a 25-term aroma vocabulary with defined references for intact cannabis flowers. A human panel assessed 91 samples. The authors reported that the measured terpene and volatile sulfur profiles did not strongly predict sensory perception across their dataset. [1]

This is a review of an existing paper, not a newly announced discovery. Its value for readers lies in how it frames the relationship between description and measurement.

Why a shared vocabulary matters

Two people can use different words for a similar impression. A defined vocabulary helps make the intended meaning visible. In a collection record, the most useful description identifies who supplied the note, what material it concerns and whether it reflects an observation or a general cultivar description.

Our editorial recommendation is to keep a sensory field separate from an analytical field. That lets a reader see the difference between a phrase such as citrus-like and a measured compound concentration.

The boundary between flower and rosin

The study concerns intact flowers. Its findings should not be presented as direct validation of a live hash rosin aroma scale. A claim about a different material would need evidence concerning that material. The same principle applies when moving from a cultivar description to a particular batch.

A thoughtful comparison can still ask whether the vocabulary is useful, while making clear that usefulness and scientific validation are different questions.

Read a flavour note with three questions

• Is this a sensory description or a chemical result?
• Does it concern the same material and sample being discussed?
• Are the words defined clearly enough for another reader to understand?

Use those questions alongside the aroma chemistry guide. They help turn an appealing description into a transparent record.
