// Definition
The water fraction obtained during steam distillation or fresh-plant extraction. Rich in water-soluble terpenes (like geraniol), the hydrosol is the vehicle that carries essential oils during distillation via Raoult's law minimum boiling point azeotrope. Rose hydrosol was valued at $5,000/pint by Romanian rose oil companies.
// From the Episode
Named 'word of the week' during EP125. John (10) described extracting fresh cannabis plants within an hour of harvest, yielding both live resin oil and approximately a quart of milky white terpene-rich hydrosol. Mark Scialdone explained the science: water creates a minimum boiling point azeotrope with essential oil components, enabling steam distillation of water-insoluble compounds. John's cotton-wad method: soak cotton with hydrosol, put in extraction chamber, use butane to separate terpenes from water.
