Fleur de sel ('flower of salt') is the thin crust of delicate crystals that forms on the surface of salt-marsh ponds under specific sun/wind conditions, hand-skimmed before it sinks and mixes with the coarser gray salt (sel gris) below; it retains higher moisture and trace-mineral content than refined table salt.
Produced in the Guérande peninsula's traditional tidal salt marshes (marais salants) in Loire-Atlantique, Brittany, by paludiers who channel seawater through shallow clay-lined pans and rake the surface crystals with a wooden tool — a technique little-changed since the Middle Ages.
Guérande is the most internationally recognized French fleur de sel origin, sold globally as a premium finishing salt to fine-dining kitchens, gourmet retailers and artisan food brands; typical annual fleur de sel yield per marsh is very small, keeping supply constrained relative to demand.
'Sel de Guérande / Fleur de sel de Guérande' holds EU Protected Geographical Indication (IGP) status, restricting the name to salt produced and hand-harvested in the designated Guérande marshland by registered paludiers; buyers should request the IGP certificate and Label Rouge documentation where claimed.
