Salty Notes

Harvesters dive along rugged coastlines to collect mature fronds of kelp and other marine algae during low tide. They rinse the material in seawater to remove sand, then spread the fronds in thin layers under shade to dry naturally for several days. Once moisture falls below 10 %, the dried biomass enters a high‑pressure CO₂ extraction chamber. Supercritical CO₂ acts as a solvent, pulling volatile marine compounds while leaving mineral salts behind. The extract condenses into a clear amber liquid that carries the signature briny aroma, rich in dimethyl sulfide, aliphatic aldehydes, and trace alginic acids. Producers filter the liquid through food‑grade membranes to ensure purity, then store it in inert glass bottles away from light. This method preserves the delicate balance of mineral and vegetal facets, delivering a note that feels both fresh and anchored in the sea.
