CO2 extraction is a type of supercritical fluid extraction used to maximize the cannabinoids and terpenes of the marijuana plant while still maintaining their delicate structure. A supercritical fluid behaves both like a gas and like a
liquid-diffusing through solids like a gas but dissolving compounds like a liquid. The supercritical CO2 goes through a series of extraction vessels at specific pressures and temperatures, flooding the ground plant material and extracting
those clean cannabinoid profiles. It is then separated and filtered from the plant material and, after the extraction is complete, a drop in pressure allows the excess CO2 to evaporate, leaving the cannabis oil behind. The benefit of CO2
extraction is that it is naturally occurring and leaves behind no residues. Other examples of CO2 extractions in the food industry include the extraction of flavor oils from hops in the brewing industry and extraction of caffeine from
coffee beans. Fun Fact: Most concentrates are made using shake, trim and undesirable buds that aren’t fit to smoke.
