Steam Distillation

A distillation method where steam is passed through plant material to vaporize volatile aromatic compounds, which are then condensed back into liquid form.

How It Works

Direct steam injection passes steam through botanical material. The steam carries volatile oils and aromatic compounds upward, where they are condensed and collected. Each ingredient has its own tailor-made formula with specific parameters for pressure, time, and temperature.

Parameters

Temperature, steam pressure, duration — each botanical requires its own calibrated formula

Best For

Robust botanicals where direct heat contact extracts desired compounds efficiently

Comparison

More aggressive than vacuum distillation but captures a broader aromatic spectrum. A.I.R. uses direct steam injection as one of four core techniques.
