How Fresh-Frozen Extraction Works

Fresh-frozen extraction takes fresh-cut flower and holds its full terpene profile in place by freezing it within hours of harvest. The frozen flower is then extracted cold, at -90 C, for selective separation of cannabinoids and terpenes from chlorophyll and lipids. It is the starting point for the Live Diamonds Waxx Brandz makes.

01

Why fresh frozen

A cannabis flower harvested at peak trichome maturity is at its terpene maximum. The volatile aromatic compounds that produce flavor and effect are at their highest concentration. From that moment, terpenes start to degrade. The traditional dry-cure cycle takes 14 to 60 days, during which 30 to 60 percent of the terpene profile is lost to evaporation, oxidation, and conversion. Freezing the flower fresh, within hours of harvest, stops the loss. The flower goes from plant to cryo within the same operating shift. The terpene wall stays intact.
02

Why we extract cold

Hydrocarbon extraction at warm temperatures pulls everything: cannabinoids, terpenes, lipids, chlorophyll, waxes. The result is harsh and requires heavy post-processing. At minus 90 Celsius, hydrocarbon extraction becomes selective. Lipids, chlorophyll, and waxes stay inert. Cannabinoids and terpenes flow through. Less post-processing, more of the original plant in the final product.
03

Live resin vs cured resin

Live resin is hydrocarbon-extracted from fresh frozen flower. Cured resin is hydrocarbon-extracted from dried, cured flower. Live resin retains the terpene profile of the harvest moment. Cured resin retains the terpene profile of the cured flower, which is partially degraded. Side-by-side, live resin smells and tastes like the plant smelled when it was harvested. Cured resin tastes like the plant tasted three weeks later.

FAQ

Quick answers.

What is fresh-frozen extraction?

Fresh-frozen extraction is the technique behind live resin, where flower is frozen within hours of harvest, then extracted cold at -90 C using hydrocarbons. The cold holds the full terpene profile and selectively separates cannabinoids from chlorophyll and lipids.

Is fresh-frozen flower the same as live resin?

Live resin is the product of fresh-frozen extraction. The flower is frozen fresh, then extracted at -90 C, and the resulting concentrate is called live resin.

Why do brands not all extract from fresh-frozen flower?

Fresh-frozen extraction requires cryo storage, a specialized extraction line, and tighter handling protocols. Most brands cure their flower first because it is operationally simpler. Waxx Brandz built around fresh-frozen flower because the terpene preservation is the entire point.
