// Definition
A solventless technique that uses controlled heat and pressure to physically separate terpenes from THCA in rosin, as distinct from chemical extraction. The process moves terpenes away from cannabinoids rather than extracting them from a matrix.
// From the Episode
Caitlyn emphasized this is fundamentally different from traditional extraction. The filter bag holds THCA in place while heat and pressure move terpenes away. She described it as separation rather than extraction, yielding distinct fractions with wildly different effects and potency levels. Multiple panelists compared the technique to candy-making and sugar work.
