VAPOR_SEPARATION
The Spirit Extraction
The literal alchemical act: matter boiled until its spirit rises, the vapor caught and condensed apart from its body. Separation by volatility — the oldest transmutation still practiced.
Voltage is tuned to the boiling point of the target fraction; the current is the vapor column itself, ascending, refluxing, and surrendering its cargo to the condenser. Each pass purifies.
P_total = Σ xᵢ · Pᵢ°Vapor composition is enriched in the more volatile component — the principle every still exploits.
This transmutation leans fire.
Methanol foreshots rise first, ethanol hearts follow, fusel tails lag behind — the column sorts molecules by boiling point, and the distiller's blade falls between fractions.
Esters and aldehydes hitchhike with the hearts in trace amounts, carrying the source material's signature through the phase change. Spirit without congeners is mere solvent.
Component-specific boiling/condensation windows; ethanol-water systems center around 173°F+.
Distillation has ancient origins, with evidence of the technique dating back to at least 3000 BCE in Mesopotamia. It was further developed by alchemists and has been crucial in perfumery, medicine, and spirits production throughout history.
