No solvents, just ice water, heat and pressure. This is one gram of Key Lime Tart rosin from Alchemy Pure. Alchemy Pure grows its cannabis in real soil and sun on a Hudson Valley farm in Millerton, then extracts it without solvents. Ice water extraction separates the resin from the plant, and pressing turns it into rosin that carries the flavor of the flower it came from. Use it in a dab rig or a concentrate vaporizer at a low temperature to keep the taste. Store it cold so it holds its texture. Rosin is far stronger than flower, so start low with a dab about the size of a crumb and wait before taking another.
