Solventless cannabis extracts are going commercial. There have been several technological innovations in this area. Each method delivers a different kind of solventless extract. Here are some of the most common solventless extracts that you may come across.
Rosin
Rosin is highly pure, potent, and flavorful, and it’s one of the most popular solventless concentrate California-based varieties. This extract is obtained through the application of heat and pressure to cannabis flowers, trim, kief, or trichomes. The extract is squeezed out as a sappy, amber-hued resin. In most instances, Rosin has a shatter-like consistency. It can also be manufactured into various textures that resemble wax, shatter, budder, and crumble.
Rosin Budder
This is a “whipped” type of rousin that is made by applying some heat and agitation. The whipped rosin usually resembles butter or frosting. Rosin budder has a consistency that ranges from saucy to a more crumbly product.
Hash
This is the oldest solventless extract that is obtained by squeezing together kief and resinous trichome glands. There are several ways to make hash. Some people make it using ice, and some older methods include hand-rubbing flower buds and scraping off sticky trichomes using a knife. The quality and color of hash vary depending on the cannabis cultivar and growing conditions. Either way, hash oil is the most fragrant, and it packs a serious punch.
Dry-sift Kief
This solventless extract is made by sieving fresh and dried flower buds using different mesh screen filters. The idea is to separate plant matter from the fragrant and powdery kief. Dry sift kief can be made by hand-shaking or mechanically agitating plant materials over a variety of mesh screens.
These are some of the most common solventless extracts. Each method of solventless extraction delivers a different kind of extract with particular properties.
