// Definition
The practice of maintaining cannabis material and extracts at consistently low temperatures (below 4 degrees Celsius) from harvest through processing and storage. Cold chain preservation retains volatile monoterpenes and prevents degradation of cannabinoids.
// From the Episode
Bubbleman discussed how keeping hash in a freezer preserves monoterpenes but noted that curing hash at room temperature allows sesquiterpenes to develop a richer, more complex bouquet. Adam Ill (Wolf Mountain) explained that the forest taught him about cold chain when harvest temperatures hit zero and frost formed on flower, and he has cured flower for eight years with flavors that 'recomposed rather than decomposed.' He lamented that many LA producers still don't maintain cold chain.
