// Definition
Rosin made by pressing dry sift hash between heated plates rather than pressing flower or water hash. This produces a particularly clean and potent concentrate, as the starting material is already refined trichome heads.
// From the Episode
Bubbleman claims to be the first to demonstrate dry sift rosin on Hash Church Ep 025, wrapping the sift in a 25-micron screen before pressing. He says nobody had been making dry sift rosin at that point and he wanted to be the one to 'bust it out.' The result was a gold-colored rosin that he photographed. He credits the overall rosin technique evolution to Jeff Church and Soil Grown.
