The organic winegrowers' association was founded in 2001 by the French cult winegrower Nicolas Joly, owner of the Loire vineyard Château de la Roche-aux-Moines (Savennières). Wineries that are committed to natural, environmentally friendly viticulture according to organic and/or biodynamic principles and have been certified as such for at least three years are eligible for membership.

The common basis is the quality charter, which was defined by the founding members and the board of directors such as Nicolas Joly, Anne-Claude Leflaive and Olivier Humbrecht. This largely corresponds to the usual rules for the production of natural wines. There are around 230 member wineries from 13 countries, most of them in France. The wineries are classified with one to three green stars. Meetings with seminars and wine tastings are held regularly, including as part of events such as ProWein.

I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
