At Oiselinière vines have been grown for centuries--in fact leases written on parchment dated 1337, 1471,1505, 1546 have been preserved. On the parchment dated from 1635 in particular, there is the first mention of Muscadet. It is the first known lease today and is written as follows: “Jean de Goulet de la Fosse de Nantes leases to several private individuals from the Parish of Gorges, a piece of land consisting of 78 plots, known as “Les Grands Gâts” dependent on the land of the Oiselinière in order to plant white Muscadet vines.” The vineyards of Château de l’Oiselinière are grown on the ridges and the plateau which look over the right bank of the Sèvre, facing south-westwards. The property has a total surface of 43 hectares planted with Muscadet vine-plants(still termed Melon de Bourgogne). The average age of the vines is 40 years, with certain plots more than 70 years. These vines yields very mature, concentrated grapes from which are derived the distinctive qualities of the Oiselinière wines.
