The winery is located in the commune of Saint-Andelin on the upper reaches of the Loire. It became known and famous through Didier Dagueneau (1956-2008), who died in a plane crash and was called a "rebel" all his life because of his unorthodox lifestyle and winemaking techniques. He came from a long-established family of winemakers, but in his youth was more interested in motorbikes than winemaking. Dagueneau became a professional motorcross rider and was one of the best sidecar riders internationally in the early 1980s. He was also a well-known musher (driver) in sled dog races and won European and World Championships. He then returned to St. Andelain in 1989, leased a small vineyard parcel and began his winemaking career as a self-taught winemaker. Without contact with his father or other winemakers in the appellation, he advanced as an outsider to become a cult winemaker in just a few years and became internationally known. The vineyards cover 11 hectares of vines in the Pouilly-Fumé appellation. He was the first in the region to convert to biodynamic viticulture and from this developed the "Dagueneau system" named after him.
The perfectionist constantly developed his very own philosophy of winemaking. Through fermentation in barriques and long ageing on the lees, the wines achieve a high complexity with lush mineral notes. A special wine is "Astéroide", which comes from ungrafted Sauvignon Blanc vines with extremely low yields. Specifically, it is the first 18 rows of the "La Folie" plot. Of these, only about 300 litres of wine are produced annually. Dagueneau described this his wine as "natural beauty close to madness". The other Pouilly Fumé wines are called "Pur Sang" and "Silex", as well as "En Chailloux" and "Buisson Ménard". In Chavignol, two mini-plots totalling 0.5 hectares were acquired in absolute top locations, of which a Sancerre is produced, as well as an old vineyard in Jurançon called "Le jardin de Babylon".
