A delicate gift of the ocean, the sun, the wind and the traditional know-how of salt workers, Guérande salt has been harvested by hand in salt marshes of the Pays de la Loire for thousands of years.In the Guérande salt marshes, salt production is a 100% natural process. Thanks to a series of tanks promoting the evaporation of water, the salt contained in the seawater concentrates until it crystallizes and becomes harvestable. Under the rays of the gentle Breton sun, wet heat and wind the the seawater evaporates little by little and the salt concentration increases to become the unique (and valued) Guérande salt.
