What You Need to Know
The process uses reduced pressure to lower the boiling point of solvents, allowing gentle evaporation of terpenes and essential oils. Ethanol is typically used to ensure food‑grade safety, and precise temperature control prevents thermal degradation of heat‑labile aromatics. The resulting concentrate is a volatile oil blend that can be applied as a garnish.
