Since 2000, the Domaine de la Coche has belonged to the two cousins Emmanuel and Laurent Guitteny, who combine the family wine tradition with recent techniques and their know-how.

The climate being oceanic, the vines benefit from the mildness and the Lake of Grandlieu protect them from heavy rainfall.

"We exploit several types of soils, to which we have adapted the grape varieties according to their potential".

   - The sandy-gravelly terroirs, where the soil is entirely covered with small white pebbles, thus allowing the heat and light to reflect on the grapes for perfect ripeness.
   - The schistous terroirs, letting the roots go down to the deepest part of the soil, following the faults of the rock to recover the mineral salts and trace elements.
  - Gneiss soils, bringing an original mineral richness to the wines.
   - The sandy clay soils, interesting for the rapid maturation of the grapes.

 
"The 36 hectare estate is in conversion to organic farming. The main appellation is Muscadet Côtes de Grandlieu, but we also use local grape varieties such as Grolleau, Grolleau Gris, Chardonnay, Sauvignon or Gamay. Our wines are regularly recognized for their quality in national or international competitions. "

Visits in June, July and August by reservation, depending on the availability of the producer.

Since 2020, the Domaine is in conversion to Organic Agriculture.
