Depending on the end products desired to be produced, the equipment, solvent and processes utilized vary substantially. Hydrocarbon (Butane, Propane and Pentane) solvent extraction is best for certain products and ethanol solvent extraction for others.
Shatter, butter, live resin, sauce, THC-a crystalline and THC HTFSE (high terpene full spectrum extract) are not able to be produced utilizing ethanol as a solvent.
Other products, including but not limited to THC distillate, full spectrum CBD (THC free) CBD isolate, CBD distillate, and CBD full spectrum extract (low THC), are readily produced with ethanol, albeit utilizing different processes than hydrocarbon.
The chart below offers a comprehensive breakdown of products versus processes in cannabis and hemp extraction. We’ve provided definitions for the products and processes seen.
