Solvent Free Extraction
Solvent-free extraction refers to mechanical or physical separation methods that isolate cannabinoids and terpenes without using liquid solvents like butane, propane, or ethanol. Common techniques include rosin pressing (heat and pressure), dry sift (mechanical agitation through screens), and ice water hash (cold water separation). These methods preserve the full terpene profile and avoid residual solvent concerns, making them relevant to breeding programs focused on phenotype stability and aromatic expression. Lineage records frequently note solvent-free extraction when evaluating cultivar quality and cannabinoid retention across generations.

Breeders working in solvent-free categories prioritize dense trichome development, high resin production, and robust terpene stability—traits that translate directly to yield and quality in mechanical extraction workflows. Selecting parents with strong glandular density and aromatic resilience supports consistent output when breeding for solvent-free processing chains.
