Cold Extraction

Cold extraction refers to solvent-based cannabinoid and terpene isolation performed at reduced temperatures, typically below room temperature or in sub-zero conditions. This technique aims to preserve volatile aromatic compounds that may degrade under heat, making it relevant to terpene profiling and breeding discussions. The process is commonly associated with concentrate production methods rather than a terpene itself, though breeders and extractors reference it when discussing terpene preservation during post-harvest handling. Cold extraction workflows frequently report higher retention of minor terpenes and more complex aroma profiles compared to heat-based methods. Understanding extraction temperatures is important for genetic evaluation, as different cultivars show varying terpene stability profiles.

Breeders working with terpene-focused selections often reference cold extraction data when evaluating which genetic lines produce the most volatile and delicate aromatic compounds. Strains bred for specific terpene combinations may be assessed through cold extraction protocols to determine true chemotype expression without thermal loss.
