Dry Sift Hash is one of the simplest forms of hash to create. It requires minimal equipment and processing input, yet it has the potential to stand beside Bubble Hash as a quality solventless source material for rosin. But just because making Dry Sift Hash is simple, that doesn’t mean it’s necessarily easy. Especially if superior quality is your aim.
Sifting dried and cured cannabis material allows us to separate and isolate trichome heads from their stalks, thereby capturing the highest-potency aspects of the cannabis plant. Dry sifting is a purely mechanical process, using your two hands and a set of specialty screens designed for the purpose. No solvents are used for extraction. It’s simpler than bubble hash, as it doesn’t require the washing and drying process, or supplies like a sprayer, multiple work buckets, ice, etc.
The objective of sifting, or sieving as it’s also called, is to knock the trichome heads free of the stalks upon which they grow and mature. As the trichome heads are liberated from their stalks, they become small enough to pass through the tiny holes in the sifting screens. While the plant material remains above the screen, trichomes rain down through the screen where they can be easily collected. Dry sift hash is the original solventless cannabis concentrate. 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. It’s possible to achieve a full-melt hash using dry sifting techniques, without the additional equipment, time, and labor to wash Bubble Hash.
