Live Resin refers to cannabis or hemp resin produced from a solvent-based extraction using freshly frozen bud. Technically, provided the starting material is freshly frozen, the extraction process can work with any number of solvent-based methods, including butane, propane, CO2, and an increasingly popular solvent called R134a.
(This shouldn't be confused with solventless extraction, which also uses fresh frozen flower. As the term suggests, solventless processes use no solvents, resulting in live hash or live rosin. All live concentrates, whether from solvent or solventless extractions, are full-spectrum, high-terpene concentrates, but with different uses.)
All solvent-based extraction methods have a few things in common. First, it all happens at super-low temperatures to help preserve the strain's terpene profile as it was when first harvested. Second, while the equipment and complexity varies, the process tends to follow the same basic steps:
- Soak and wash: Frozen flower is soaked and washed in solvent to gently strip the trichomes (terpene and cannabinoid-rich oils) from the plant material.
- Filter: The non-spent plant material is removed from the solvent.
- Solvent Recovery: The solvent is evaporated by heating to its natural boiling point, leaving a highly purified concentration of cannabinoids and terpenes with no solvent residues.
Every solvent has pros and cons, yet when it comes to live extractions, R134 stands out as one of the safest and most efficient solvents used today. This is because R134a, a hydrofluorocarbon, has an incredibly low boiling point (−15.34 °F), which ensures solvent evaporation can happen at room temperature without unnecessary heat.
No heat means superior terpene preservation — which is the name of the game of live concentrates. Thanks to this advanced R134a extraction, Hometown Hero Live Resin vapes are unlike anything else you've tasted.
