the formation of salt crystals is a natural phenomenon that relies on climatic conditions. The nature of the wind in combination with sun conditions and air humidity determine the specific crystallization of fleur de sel sea salts. On some days, no crystals are formed, on other days, an abundance of rare crystals are born. The expertise of the salt basin artisan is crucial in order to take advantage of these rare weather conditions. The “Vent D’est” and the “Neige” of our sea salts are some of the rarest and most precious sea salts in France.
