Dry sift, also known as kief, dry sieve, or dry sift hash, is a cannabis concentrate extraction method that dates back to ancient times. It is created by sifting cannabis plant material through a series of screens, with no use of chemical solvents or water in the process. The name “dry sift” reflects this absence of solvents, and the result is a concentrated product rich in trichomes and terpenes.
Key characteristics and features of dry sift include:
Screen-Based Extraction: Dry sift is produced by rubbing cannabis plant material on a series of screens with different micron grades. This process allows trichomes, the resinous glands on the plant, to fall through to subsequent screens for further refinement while plant material is filtered out.
No Chemicals or Water: Unlike some other extraction methods, dry sift does not involve the use of chemical solvents or water. It relies solely on mechanical separation to concentrate the resin.
Potency: Dry sift is known for its high potency, often containing THC levels ranging from 50% to 60%. This makes it a preferred choice for consumers looking for a strong cannabis concentrate.
Versatile Use: Dry sift can be consumed in various ways. It can be pressed together to form hand hash or sprinkled on top of a bowl of flower to increase its potency.
Sustainability: Many growers choose to harvest dry sift by trimming cannabis above a sieve, allowing the fallen trichomes to be collected for the production of dry sift hash, minimizing waste.
Dry sift is considered a natural and traditional method for creating cannabis concentrates, free from chemical additives. Its versatility and high potency make it a popular choice among cannabis enthusiasts.
