Kief and Dry Sift Explained

Kief is a solventless cannabis concentrate made of the loose resin glands, called trichomes, that fall off the plant. It collects naturally in the bottom chamber of a three or four piece grinder, where a fine screen lets it sift through. Dry sift is kief collected on purpose by shaking material over fine screens. Kief is a light green to golden powder that is sprinkled on a bowl or pressed into hash.

Kief is the most basic concentrate: no solvent, no water, no heat, just the resin glands separated from the plant. Many people already have some without knowing it, sitting in the kief catcher of their grinder. Dry sift is the cleaner, deliberate version, sifted through stacked screens to separate the resin heads from plant matter.

Kief separates on its own. When dried flower is ground or handled, the brittle resin glands break off, and a fine screen lets them fall through while the plant material stays above. A three or four piece grinder does exactly this in its bottom chamber.

Dry sift is the same idea done deliberately: dried material is gently worked over a series of fine screens to collect cleaner resin. No solvent, water or heat is involved.
