How is rosin made?

Thursday, Jan 28, 2021

Rosin is a solventless cannabis extract that’s made using heat and pressure. It can be made from kief, flower, trim, or ice hash (sometimes referred to as bubble hash). At Dialed In, our rosin is made from ice hash, meaning that the trichomes must be extracted from our starting material before it’s ready to be made into rosin. More details about how this is done can be found in our ‘What Is ice hash?’ post.

The process of making rosin begins with filling 25u micron screen pouches with ice hash, and then placing the filled pouches into our rosin press. These pouches are sandwiched by parchment paper. Then a combination of mild heat and pressure is applied. The temperatures that we use range from 160°F to 210°F, staying as low as possible to preserve terpenes. The amount of pressure should also start low and slowly increase over time.

As heat and pressure is applied by the rosin press, the trichomes’ outside membrane is squeezed and broken down. This results in oil (rosin) coming out of the press in a homogeneous consistency. The rosin is rich in both terpenes and cannabinoids, while leaving behind trichome husks (also known as membranes) inside of the 25u micron bag. A major benefit of this process is having a final product that’s free of chemicals and hydrocarbons. It also offers a cleaner melt than ice hash when dabbed, since there is no cell membranes or natural plant waxes remaining inside of rosin.
