King of Salt is a salt manufactory in Bad Essen in the Osnabrück region (Lower Saxony). The family promotes, refines and markets a salt-rarity: the Bad Essen Urmeersalz (primordial sea salt).
220 million years ago where Osnabrück is today, there were once palm beaches and dinosaurs. The North German Plain and therefore the Osnabrück region was covered by a sea, the primordial sea. The primordial sea was created by a subterranean volcano, which is stuck 2.5 kilometers below the surface of the earth. Through the breaking up of the soil layers, a small amount of precious primordial sea was sandwiched between two layers of clay. Consequently, Bad Essen is the only place in the world on which no rock salt from the primordial sea has formed. Here instead, it has remained liquid for millions of years. The Bad Essen primordial sea reservoir lies at a depth of 800m and is unaffected by environmental influences. It contains sulphur, manganese, potassium, calcium, magnesium and many other minerals that are not found in these percentages in any other salt in the world.
