Solventless rosin vs live resin are both popular cannabis concentrates, but they differ in production methods and effects. Solventless rosin is made by pressing cannabis flower or hash under heat and pressure, without using solvents, which preserves the full spectrum of cannabinoids and terpenes. In contrast, live resin is made from freshly frozen cannabis and uses solvents (like butane) to extract the oils, resulting in a more potent concentrate with intense flavor. Both offer clean and potent effects, but rosin is the choice for those seeking a solvent-free experience.
