Live rosin is a solventless cannabis concentrate made from fresh-frozen cannabis plants. Frozen plants are placed in a rosin press, which uses heat and pressure to extract a hot oil from the plants, which is rosin. The “live” in live rosin means frozen plants were used as the source material; when dried cannabis plant material is used, it is just rosin.
Live rosin vs. live resin
The term “live” means that fresh-frozen cannabis plants were used to make an extraction. Frozen plants can be used to make both a rosin or a resin, giving them the names “live rosin” and “live resin.” Simple rosins and resins are made with dry cannabis plant material.
Live rosin and rosin are both solventless extracts made using a rosin press, where heated plates press nugs to extract a hot oil. Live rosin and rosin are both consumed in a dab rig, and both are made by hand, typically making them more expensive than live resin.
Live resin is a solvent extraction, created using chemicals such as butane in a closed-loop system. Live resin is usually less expensive than live rosin or rosin.
