Alcohol Extraction

The process of extracting terpenes and trichomes from a cannabis plant using alcohol is called Alcohol Extraction. This interaction is achieved using ethyl or isopropyl alcohol. The cannabis plant is soaked in alcohol and then filtered out using a straining process. The remaining alcohol is left to evaporate and leaves behind a sticky resinous layer of hash oil. Other processes that use further purification such as heat, agitation, or vacuum pressure can produce oil, shatter, rudder and a variety of textures.
