The organic wine association was founded in 2001 by the French cult winemaker Nicolas Joly, owner of the Loire vineyard Château de la Roche-aux-Moines (Savennières). Membership is open to wineries that have committed themselves to natural, environmentally friendly viticulture according to ecological and/or biodynamic principles and have been certified for at least three years. The common basis is the Quality Charter, which was established by the founding members and the board of directors such as Nicolas Joly, Anne-Claude Leflaive and Olivier Humbrecht. There are well over 200 member companies from 18 countries, most of them in France. The wineries are classified with one to three green stars. There are regular meetings with seminars and tastings, also within the framework of events such as ProWein.
