Dry sift
Dry sift is trichome separation by sieving dried plant material — the historical method behind Moroccan and Afghan hash, refined today with meshes calibrated in microns.

The principle has not changed in a century: dry, cold material, a screen, a steady gesture. Brittle trichomes break off and pass through the mesh; the collected powder (kif in Morocco) is then pressed into slabs, hot or cold. All the modern sophistication lies in calibration — screens graded from 220u to 45u — and in temperature control, cold making trichomes more brittle and the sort cleaner.
Its contemporary variants are called static sift (with complementary electrostatic sorting) and "00"/triplo filtrato (successive screenings). Against ice-water methods, dry sift keeps two advantages: no contact with water, hence an intact aromatic profile, and a simplicity that suits small artisanal batches.
Unpressed, the same powder is also sold as kief, the English spelling of kif, or as pollen in the hemp trade. The stated characteristics and percentages of the related products appear on their pages. Without a dated batch certificate, a product profile is not a verifiable analysis.
