Distillate is a refined extract. Live resin is made from cannabis frozen at harvest rather than first dried and cured. Live rosin is a solventless extract: ice water, heat, and pressure are used instead of chemical solvents.

Rosin is pressed with heat and pressure. Live resin is extracted from plants frozen at harvest. Distillate is refined until it is close to neutral in aroma.

For the most refined of the three, see refined distillate, for contrast. Whichever extract you are curious about, the composition line on the pack in hand names what that product uses.
