Live resin is a type of cannabis concentrate that is manufactured using a technique that takes freshly harvested cannabis and freezes it to subcritical temperatures prior to and throughout the extraction process.
Where these methods differ from other extraction processes is in the amount of time harvested cannabis plants are allowed to dry and cure before the extraction.
The drying and curing process that a cannabis plant typically undergoes can have a devastating impact on terpenes, the flavorful factory molecules present within the trichomes that line virtually every corner of a mature cannabis flower and its surrounding foliage.
With cured concentrates, the cannabis plant is allowed a certain amount of time to wick itself of moisture and chlorophyll before the extraction occurs.
During this time, trichomes are subjected to conditions not conducive to terpene preservation. Interactions such as increased exposure to heat, oxygen, physical agitation, and light all play a role in degrading terpenes.
