The reputations of Live Resin and Live Rosin have been growing quickly amongst the cannabis savvy consumer. The increased demand for extracts sporting fresh flavours and well-preserved mono-terpene profiles has caused more extraction professionals and companies to consider adopting these methods. Both methods have their own unique benefits and drawbacks and are also similar in a lot of ways. Industry professionals are well advised to take careful consideration of the potential costs and scalability these processes may offer compared to a standard hydrocarbon extraction or water hash processes.
To begin, it is important to discuss some of the major differences. Live Resin is an extraction process, where Live Rosin is a mechanical separation process. The process of making Live Resin consists of using solvents, particularly butane and propane, to dissolve the terpene and cannabinoid compounds when soaked in frozen cannabis biomass. From this process a variety of consumer cannabis products can be produced, including diamonds and sauces, various concentrate textures like caviar or batter – really there is no limit to the kind of textures you can make!
On the flip side, Live Rosin is either the final product or it can be used in such products as infused pre-rolls and occasionally cartridges that are completely solventless. The process uses mechanical separation in multiple stages, and that’s why it’s not technically an extraction, as the oil is never dissolved like in an extraction process. That appeals to the cannabis purists because the end product does not come in contact with solvents during production at all. Simply put, the trichomes get sifted to separate them from the plant matter, what we call a mechanical separation. After the ice water has separated the trichome glands or heads, that hash separated from the water and then freeze-dried. Then the Live Rosin is squished out of the dried hash in a rosin press. This process is more time consuming compared to Live Resin, simply due to the bottlenecks in rosin production.
Overall, Live Resin provides a higher yield. The use of a solvent allows a higher proportion of cannabinoids and terpenes that exist in the biomass to be collected. It’s also more easily scaled and provides a product that is in the price range of a large base of consumers for those reasons. Live Rosin demands a premium, and for good reason but the market size remains a bit smaller due to the higher cost of production and resulting product price to consumers.
