Terroir
Natural factors
- The vineyard stretches from the foothills of the Mauges in the east to the Atlantic coast in the west, and from the banks of the Loire in the north to the Vendée plains in the south.
- The geographical zone encompasses 68 communes spread across the départements of Loire-Atlantique, Maine-et-Loire, and Vendée.
- The ancient geological basement combines plutonic formations such as granites and gabbros with metamorphic rocks including gneiss, mica schist, amphibolite, and eclogite.
- The vineyards are planted preferentially on the hillocks and slopes around Lac de Grandlieu and its tributaries, as well as on the hillsides of the Goulaine marshland and the Loire valley.
- Atlantic influence penetrates deeply through the Loire estuary, with particularly mild winters encouraging early soil warming and cool summers tempered by sea breezes.
- Rainfall is relatively well distributed throughout the year but shows a marked deficit in summer, while sunshine levels remain high for this latitude.
Human factors
- The Folle blanche variety, renowned for its use in spirits production, was established in the sixteenth century under the impetus of the Dutch wine trade, and the name 'Gros Plant' appears in writing for the first time in 1732.
- The 'méthode nantaise' consists of keeping wines on their fine lees from vinification for at least one winter without racking; the 'sur lie' designation for this practice was regulated in 1977, with bottling required within the geographical zone or its immediate surrounding area.
Product characteristics
- The wines display a very pale yellow colour, sometimes with green highlights in their youth, with a palate defined by an acidic balance dominated by freshness and lightness.
- Wines carrying the 'sur lie' designation generally show a rounder balance on the palate and may display a light spritz due to residual carbon dioxide from the alcoholic fermentation.
- On the nose, the wines develop subtle aromas with a predominantly fruity or floral character, frequently accompanied by a briny, iodine-tinged note.
Terroir / wine link
- The coarse, acidic soils developed on granites, gneiss, mica schists, or sandy-gravelly deposits, combined with the mild winters of the Nantes climate, encourage an early start to the growing cycle and the achievement of full grape ripeness.
- The northerly situation of the vineyard and its exposure to Atlantic influences ensure cool summer temperatures, which helps preserve the delicate aroma precursors present in the grape berries.
