Curing Biochemistry

Curing biochemistry encompasses the chemical transformations that occur in cannabis plant material during the post-harvest drying and curing process. During this period, chlorophyll breaks down, moisture content stabilizes, and enzymatic activity modifies cannabinoids and terpenes through oxidation, decarboxylation, and other reactions. Terpene profiles shift notably—some volatile compounds evaporate while others recombine or isomerize into different molecular forms. Breeders and cultivators monitor these changes because final flavor, aroma, and chemical composition depend heavily on curing conditions. Understanding curing biochemistry helps explain why identical genetics can yield different sensory profiles based on post-harvest handling.

Breeders select for genetic stability during curing—preferring lines where desirable terpenes and cannabinoids remain robust through standard drying protocols. Curing biochemistry knowledge informs breeding goals around terpene abundance and oxidative resilience, since some cultivars retain volatile aromatics better than others under identical curing conditions.
