Château des Vaults in Savennières dates back to 1495 and was inherited by Michèle de Jessey in 1962 from her childless aunt Madame du Closel. Michèle and Jacques de Jessey turned the small family estate into Domaine du Closel. The entire vineyard is located on the most western hill of Savennières and includes some of the best parcels in the AOC: Les Caillardières and Clos du Papillon. The topsoil is shallow, warm, and consists of purple/green schist and sandstone, enriched with volcanic rocks (quartz, phtanites, ryolites and spilites) in the best areas. 13 of 16 hectares of vines are planted with Chenin Blanc, designated for Savennières AOC production. The flagship wine is Clos du Papillon, accompanied by a selection of white, red and sparkling wines, including three single-vineyard Savennières, crémant, and red Anjou wines.
