Volatile Terpene Profiling

Volatile Terpene Profiling (VTP) is a classification method that categorizes cannabis strains based on the detection and measurement of aromatic compounds released during plant growth, handling, or analysis. This technique identifies which terpenes are most readily detected in the headspace above plant material—typically through gas chromatography or similar analytical methods—rather than measuring total terpene content alone. VTP focuses on the most volatile (easily evaporated) fraction of a plant's terpene expression, which may differ from its full terpene profile. Breeders and researchers use VTP data to distinguish between strains with similar genetics but different aromatic expression patterns. This classification system is particularly useful for understanding phenotypic variation and predicting consistent aroma profiles across grow conditions.

Breeders working in volatile terpene selection use VTP data to identify and stabilize cultivars with distinctive aromatic signatures. Understanding which terpenes volatilize readily helps guide parent selection for offspring with predictable sensory profiles across different cultivation environments.
