Celtic Sea Salt® is authentic, unprocessed whole salt from pristine coastal regions. Our salts retain the natural balance and spectrum of essential minerals, supplying the body with over 80 vital trace minerals and elements. Light Grey Celtic® is a mineral-rich, whole crystal (coarse), moist salt that is completely unrefined and hand harvested. Dried by the sun and the wind; it retains the ocean's moisture, locking in a vast array of vital trace elements. Light Grey Celtic® gets its light grey hue from the pure clay lining of the salt beds where it is harvested. Light Grey Celtic® is perfect for use in a grinder and for cooking. The whole crystals dissolve with heat and moisture, enhancing food with its rustic, old-world flavor while adding vital nutrients to your diet. Light Grey Celtic® is certified organic by Nature et Progrés, the highest level of certification allowed in Europe."
