What makes French Grey Sea Salt different
Most table salt is mined from underground deposits, then stripped, bleached, and treated with anti-caking agents. French Grey Sea Salt is solar-evaporated by hand from Atlantic seawater in the centuries-old salt marshes of Brittany. The natural grey color comes from the mineral-rich clay at the bottom of each pan — and that clay is what gives the salt its full spectrum of trace minerals and characteristic moisture.
