The Loire Valley is the third largest wine-growing region in France, stretching from the Atlantique coast to Auvergne. The Loire Valley vineyard is almost 1000 kilometers long, it follows the Loire from its source to its estuary, from the Massif Central to Nantes.

For the white, we mainly find: melon de Bourgogne, chenin and sauvignon blanc.

The grounds of the estate

Clau de Nell is located in the village of Ambillou-Château, in Maine et Loire, between Angers and Saumur.

The plots are located at an altitude of 101 meters at the highest point. 12 hectares in one piece between forests and fields, which allows good biological activity in the soils. In the south, the first 10 centimeters of the soil is composed of silty sand (produced by fluvial erosion of rocks, mainly composed of mineral matter such as quartz).
Deeper down, the soil is mainly sand and clay. Below, and to a depth of about 40 meters, the soil is composed of Tuffeau, historically present in the geology of Anjou-Touraine. Tuffeau is a fine-grained limestone, made up of remains of organisms and fragments of rocks brought by rivers in the form of alluvium.
