Domaine de l’Ecu is located in Landreau, in the Nantes region, at the heart of the Muscadet Sèvre-et-Maine appellation. The estate was long managed by Guy Bossard, a pioneer of organic viticulture in the region, before being taken over by Fred and Claire Niger.

The vineyard spans approximately twenty hectares and has been farmed organically since 1972 and biodynamically since 1998. Viticultural and cellar practices are based on minimal intervention, fermentations with indigenous yeasts, and varied aging methods, sometimes in amphorae.

The estate is renowned for its single-parcel cuvées that highlight the Muscadet terroirs, particularly granite and orthogneiss soils, as well as for its committed approach to biodiversity and living ecosystems.
