Rosin is a cannabis concentrate made through an extraction technique that manipulates fine hash using pressure and heat. Having a very high cannabinoid and terpene concentration, rosin is further differentiated from other concentrate products because of several important factors. The first is overall purity, the result of using only heat, pressure and sift bags with microscopic openings—as opposed to any solvents—to separate cannabinoids and terpenes from the plant. As such, rosin won’t have any solvent residue, while other techniques may require going through more steps to purify the concentrate, something that is not always fully achieved. Other positive rosin attributes include the price of production and the possibility of manipulating the concentrate into different textures and consistencies, including shatter, wax and crumble. What is the potency of rosin? Reaching the highest potency of any concentrate depends on the starting material used. Also critically important is the quality of the sifts used in the extraction process, because this also determines the concentration of the rosin. Usually, the cannabinoid concentration is around 70 percent, and can even reach more than 80 percent. It should be noted that an estimated 10 percent of rosin could be various terpenes that were present in the strain used to create the rosin. Terpenes may also play a key role in the feeling delivered via the fragrance and flavour of the rosin, but also perhaps related to medicinal effects since, when combined with cannabinoids, they contribute to the entourage effect.
