Rosin is a full spectrum, cannabis concentrate made from flower or hash. Punch Extracts solely produces Live Rosin; a higher grade of rosin. Live Rosin is produced by processing fresh frozen flowers into the hash, which is then pressed through a fine mesh to remove impurities. The reasoning behind using fresh frozen flowers instead of the cured flowers is in preserving as much of the terpenes as possible, many of which boil off at room temperature. All of this culminates in a high potency, smell, and flavor-rich, solvent-free concentrate. 1g.
