Fresh Frozen Extraction

Fresh Frozen Extraction refers to cannabis material processed immediately after harvest, without drying or curing, to preserve volatile aromatic compounds. This preservation method is commonly associated with terpene retention, as freezing halts enzymatic degradation that occurs during conventional drying. The resulting extracts often retain heightened concentrations of minor terpenes and cannabinoid precursors present in fresh flower. Lineage records and extraction lab notes frequently report that fresh-frozen starting material yields aromatic profiles notably distinct from cured-flower extracts of the same cultivar. This technique has become standard in rosin, hash, and full-spectrum concentrate production, though it requires specialized equipment and rapid processing.

Breeders working with live-rosin and solventless concentrate markets prioritize cultivars with robust terpene expression, since fresh-frozen extraction amplifies minor terpene visibility. Genetics selected for high myrcene, limonene, or pinene content often exhibit their intended aromatic character more clearly when processed fresh-frozen rather than dried.
