Dry Sifting

Dry sifting is a post-harvest extraction and separation technique rather than a terpene itself. The process involves agitating dried, cured cannabis material over fine mesh screens to separate trichome heads from plant matter, producing kief or hash. Breeders and cultivators use dry sifting to evaluate trichome density and maturity across different phenotypes, as output yield and quality reflect resin production traits. The technique preserves volatile compounds better than solvent extraction, making it valuable for studying terpene profiles in breeding programs. Dry sifting results are influenced by genetics, environmental conditions during growth, harvest timing, and curing methods rather than by specific terpenes.

Breeders monitor dry sift output and quality to select for high trichome-density lines and assess resin potential across phenotypes. Dry sift yield serves as a measurable trait for selecting parents in breeding stock development.
