Terpene Geography

Terpene geography refers to the regional and environmental patterns in terpene expression across cannabis cultivars. Certain growing regions, climates, and terroirs have historically produced plants with distinct terpene profiles—similar to how wine regions develop characteristic flavor signatures. Breeders and researchers have observed that altitude, humidity, temperature fluctuations, and soil composition influence which volatile compounds accumulate in plant tissues. Understanding terpene geography helps geneticists trace lineage origins, predict phenotypic expression in new environments, and inform selective breeding strategies. This concept bridges traditional landraces with modern cultivation science, revealing how environment and genetics interact to shape chemical diversity.

Breeders leverage terpene geography knowledge to preserve regional characteristics, predict how genetics will express in different climates, and intentionally cross lines that represent distinct geographic terpene profiles to create novel combinations. Mapping terpene patterns across origins supports heirloom preservation and informs decisions about which parent plants to select for specific culti
