Terpene Profile

A terpene profile is the complete chemical fingerprint of volatile organic compounds present in a cannabis plant, typically expressed as a percentage breakdown of individual terpenes. Each strain develops a unique profile influenced by genetics, growing conditions, harvest timing, and post-harvest handling. Common analysis methods include gas chromatography (GC) and liquid chromatography (LC), which identify compounds like myrcene, limonene, caryophyllene, and pinene. Understanding terpene profiles is foundational to cannabis breeding and cultivation science, as these compounds contribute to aroma, plant vigor, and observed user experiences. Profiles can shift significantly between phenotypes within the same strain line, making standardization a key breeding goal.

Breeders use terpene profiling to select parent plants with stable, reproducible chemical profiles and to track consistency across generations. Detailed profiles help identify which crosses produce desired aroma characteristics and inform decisions about phenotype stabilization in line development.
