// Definition
An inverted form of steam distillation where steam passes downward through plant material rather than upward, used to extract terpenes and essential oils from cannabis. Allows for different compound recovery compared to standard steam distillation, with Horatio Delbert noting that every strain requires a different extraction approach because each terpene profile responds differently to temperature.
// From the Episode
Bubbleman described Horatio’s process as “kind of a steam distillation sort of inverted version” that Horatio had refined over years of experimentation. Horatio emphasised that the first hour of distillation produces the best quality terpenes, and that explaining his full process is like a “four-year course.”
