A rosin press uses heat and pressure to extract concentrated cannabis oils, often called rosin, from plant material. This mechanical extraction method bypasses the use of solvents, resulting in a product considered by some to be cleaner and more natural. Different models exist, ranging from small, hand-operated devices for personal use to large-scale industrial equipment.
Solventless extraction has gained popularity due to its perceived safety advantages and the ability to produce a high-quality concentrate quickly. The process preserves desirable terpenes and cannabinoids, contributing to the flavor and potency of the final product. This method has evolved significantly, improving efficiency and yield over time.
