Dry sift is a form of hash that requires minimal processing to separate trichome heads from the stalks, thereby capturing the highest-potency aspects of the cannabis plant. The high concentrations of cannabinoids and terpenes make dry sift hash a premium source material to use for pressing rosin.
By itself, the highest quality dry sift hash is able to melt or vaporize completely, which is an indication of it’s purity and potency.
The name reflects the specific action required to produce this type of hash, which is essentially sifting, or passing dry cannabis material over a fine screen, in order to separate the trichome heads from the rest of the material. While trichome heads are small enough to pass through the fine screen, the stalks and other plant material cannot.
Dried and cured buds or sugar leaf (trim that is covered in trichomes) should be used for the starting material. If using larger buds, it’s best to break the buds into smaller “popcorn” sizes, while being careful during handling not to allow too many trichomes to fall off the buds before they’re placed over the screen.
Also consider the room temperature where you’ll be making the dry sift. Cooler temperatures are better, as warmer temperatures lead to a waxier or more oily sift that is a bit harder to work with. Cooler temperatures will make a more stable hash, and also help the trichomes stay brittle and more easily break away from the rest of the plant.
The tools you need are basic and include quality cannabis material with high trichome content, a pair of gloves, a fine silk screen, and a collection tray.
To make things easier consider purchasing a sifter box, from Green Goddess for example.
The technique to creating the dry sift involves friction and agitation through manually rubbing the cannabis over the screen. As the cannabis is gently rolled across the screen, the trichomes are separated from the rest of the plant and the trichome heads pull away from the stalks and fall through the tiny holes in the screen.
After the cannabis has been meticulously rolled and tumbled across the screen for several minutes, it’s time to collect the dry sift that’s fallen below. Collecting on a piece of glass is ideal, since the dry sift will be a powdery substance that would stick to rougher surfaces.
Once the dry sift is collected, it should be stored in a glass container away from heat and light.
