Description
Low‑temperature pyrolysis of alder or cedar bark creates a smoky, aromatic flavoring used traditionally by Pacific Northwest Indigenous peoples.
Technical
The process heats bark to 200–300 °C, causing thermal degradation of lignin and cellulose into phenolic volatiles such as guaiacol, syringol, and eugenol. The resulting smoke is drawn through a condenser at ~100–120 °C, preserving these volatile compounds while minimizing charred by‑products. The condensed condensate is then infused into foods or liquids, imparting characteristic smoky, woody, and slightly sweet notes.
