Cold-cure rosin is a finishing process applied to fresh-pressed live rosin. Within minutes of pressing, the warm rosin is sealed into a glass jar and held at 55°F for 72 hours. During this hold, lipids in the rosin re-crystallize and terpenes relax into a thinner, pourable consistency. The result is a brighter, more terpene-rich expression than warm-cured rosin — particularly noticeable in cartridge form, where cold-cure rosin holds its terpene character through the heat of vaporization.
