Aroma Intensity Curves

Aroma intensity curves describe how a cannabis strain's volatile organic compound (VOC) profile changes across the plant's lifecycle—from seedling through flowering to harvest and curing. Breeders and cultivators track these patterns to understand when terpene production peaks, which compounds dominate at different growth stages, and how environmental conditions (temperature, humidity, light) influence aroma development. Intensity curves vary significantly by genetics; some strains show early, sharp terpene expression, while others develop complexity gradually. Measuring aroma intensity—via sensory evaluation, headspace analysis, or gas chromatography—helps breeders select for consistency and desired volatile profiles. This data informs cultivation timing decisions and helps predict final aroma characteristics before harvest.

Breeders use intensity curve data to identify parent plants with desirable aromatic expression timing and strength. Selecting for stable, repeatable intensity patterns across generations helps stabilize new cultivars for commercial consistency.
