The estate is located in the municipality of Saint-Andelin on the upper reaches of the Loire, It was made famous by Didier Dagueneau (1956-2008), who died in a plane crash and who has been known throughout his life as a "rebel" due to his unorthodox way of life and winemaking techniques. He came from a long-established winemaker family, but was interested in the youth more for motorcycles than viticulture. Dagueneau became a motorcross pro and was one of the best sidecar drivers internationally at the beginning of the 1980s. He was also a well-known musher (handlebar) in sled dog racing and won European and World Championships. Then in 1989 he returned to St. Andelain, leased a small vineyard and began his winemaking career as a self-taught artist. Without contact with his father or other winemaker of the Appellation he became an outsider in a few years to the cult wine maker and became internationally known. The vineyards cover 11 hectares of vineyards in the appellation Pouilly-Fumé, He was the first in the region to start Biodynamic viticulture and developed from this the named after him "System Dagueneau".
The perfectionist constantly developed his very own philosophy of winemaking. By fermentation in and long extension to the yeasts The wines reach a high complexity with lush mineral Grades. A special wine is "Astéroide", made by ungraftedSauvignon Blanc vines with extremely low yields. Specifically, these are the first 18 rows of the parcel "La Folie". Of these, only about 300 liters of wine are produced annually. Dagueneau described his wine as "natural beauty that is close to madness". The other Pouilly Fumé wines are called "Pur Sang" and "Silex", as well as "En Chailloux" and "Buisson Menard". In Chavignol two mini-crops were acquired with a total of 0.5 hectares in absolute prime locations, of which one Sancerre produced as well as an old vineyard in Jurançon Acquired "Le jardin de Babylon".
