Harvest To Freeze Workflow

Harvest-to-freeze workflow refers to the post-harvest preservation method where fresh cannabis plant material is rapidly frozen immediately after cutting, before drying or curing. This technique is primarily used in breeding programs and extraction operations to preserve volatile terpene profiles and cannabinoid composition at the moment of harvest. Freezing arrests enzymatic degradation and oxidation that normally occurs during traditional drying. Breeders often employ this method when banking genetic material or conducting analytical testing, as it maintains a baseline chemical snapshot. The frozen material can be thawed later for processing, breeding evaluation, or archival purposes without significant loss of volatile compounds.

In breeding contexts, fresh-frozen material allows breeders to accurately assess terpene and cannabinoid profiles without the chemical shifts introduced by drying and curing variables. This standardization is valuable when comparing phenotypes across generations or preserving parental lines for future crosses.
