What Is Celtic Sea Salt? A Guide to Sel de Guérande

Celtic sea salt is a traditionally harvested grey sea salt. The coarse salt sold by Crystal Health & Beauty is Sel de Guérande, from the coastal salt marshes of Guérande on the Atlantic coast of France.

What Celtic sea salt is

It is unrefined sea salt. Seawater is left to evaporate in the sun and wind, then the salt is collected by hand. Nothing is added: no anti-caking agents, preservatives or bleaching agents.

Where Guérande salt comes from

Guérande sits on the Atlantic coast of France. The salt marshes there have been used for traditional salt harvesting for generations. Sel de Guérande is the name used for salt from those marshes. Sel gris refers to the grey colour.

Why Celtic salt is grey

The grey colour comes from contact with the clay-lined ponds where the salt forms. A little natural moisture is normal. Crystals may clump. That does not mean the salt has spoiled.

Coarse and fine Celtic salt

The Crystal Health & Beauty pack is coarse Celtic sea salt in a 500g resealable bag. Coarse crystals can be used whole, crushed, or ground in a mill made for moist salt. A fine salt is a different product: it is dried and ground to a small grain. Do not treat a fine 1kg specification as the specification for this coarse 500g bag.

Celtic salt and table salt

Table salt is typically refined to produce uniform crystals. It is usually white, dry and free-flowing, and it may contain anti-caking agents. Celtic grey sea salt is unrefined, naturally grey, slightly moist, and sold here with nothing added.

How it is harvested

Seawater moves through the marshes and evaporates naturally. Harvesters collect the coarse salt by hand. It is not washed or refined before it is packed.

How to use coarse Celtic salt

Use it to season food to taste: soups, stocks, pasta, rice, roasting, brining and finishing. It is still salt, mostly sodium chloride, so use it as you would any salt in a balanced diet.

How to store it

Keep the bag sealed in a cool, dry place. Moisture and slight clumping are normal for this kind of salt.

Iodine

Unrefined sea salt can contain trace elements. It is not the same thing as iodised table salt unless the iodine content of that specific salt has been verified.

How to choose it
