Post Harvest Processing

Post-harvest processing refers to the methods applied after cannabis plant material is dried and cured, which can significantly influence the final terpene profile and aromatic expression. Techniques such as solvent extraction, rosin pressing, hash-making, and distillation are commonly used to concentrate or isolate terpenes from plant material. The timing, temperature, and method of processing directly affect which volatile compounds are retained, degraded, or transformed. Breeders and processors working in this space focus on maximizing terpene preservation, as improper handling can oxidize or evaporate the most delicate aromatic compounds. Understanding post-harvest protocols is essential for maintaining genetic expression in seed lines and finished products.

Breeders selecting for stable, robust terpene profiles often evaluate how candidate lines respond to different processing methods, since some genetics retain volatile compounds better under specific extraction or cure conditions. This data informs which lines are best suited for fresh-frozen material, long-storage seed banking, or specific extraction workflows.
