Natural factors

The geological framework is composed mainly of metamorphic rocks — primarily micaschists and gneiss — along with broad veins of mafic rocks: amphibolites, eclogites, and prasinites.
Around the lake's perimeter, the Primary basement is sometimes covered by Tertiary sediments composed mainly of sands with a variable proportion of clays and pebbles.
The absence of significant relief between the coast and the vineyards promotes rapid inland penetration of maritime airflows, resulting in low rainfall and greater sunshine hours than in areas further inland.

Human factors

The Melon grape variety has been referred to as 'Muscadet' since the mid-seventeenth century in the region, following its introduction under the influence of the Dutch wine trade in the sixteenth century.
The 'méthode nantaise' consists of keeping the wines on their fine lees for at least one winter without any racking, contributing roundness and richness through the enrichment of mannoproteins and compounds released by the autolysis of yeast cell walls.

Product characteristics

The dry white wines display intense, fruit-forward aromas, sometimes enhanced by iodine-tinged notes, with a palate balance oriented toward freshness.
The 'sur lie' designation generally imparts a roundness on the palate, a more complex bouquet, and a slight spritz due to residual carbon dioxide from alcoholic fermentation.

Terroir / wine link

The predominantly sandy soils and mild winters encourage a very early vegetative cycle, which is reflected in the open, expressive character of the wines from their earliest age.
