Ice Water Extraction

Ice water extraction is a solventless cannabis processing technique rather than a terpene itself. The method uses cold water and mechanical agitation to separate trichome heads from plant material, producing cannabis concentrates like bubble hash and full-spectrum extracts. Because the process avoids heat and chemical solvents, it's often used by processors seeking to preserve volatile aromatic compounds and cannabinoid profiles. The resulting concentrates frequently retain a broader terpene composition compared to heat-based or solvent-dependent methods. Ice water extraction has become a standard reference point in discussions about preservation-focused processing within breeding and production communities.

Breeders selecting for processing traits often consider trichome structure and resin production stability when developing lines intended for ice water extraction. Cultivars with robust, easily-separated trichome heads and high resin yields are preferred for this technique, making trichome morphology a relevant breeding consideration for extraction-focused lineages.
