In addition to the wine and oenological routes, organic viticulture must also address the different aspects of sustainable viticulture, in particular the treatment of cellar effluent, with an ecological approach. Inaddition to wastewater treatment performance,effluent treatment must integrate different ecological orientations: low energy consumption and limiting waste (sludge) that is increasingly difficult to manage by agronomic means. In addition, in conjunction with the concept of eco-enotourism, a harmonious integration of the system can be envisaged, which combines a limitation of olfactory and noise pollution, alandscape and biodiversity enhancement as well aspossibly a reuse oftreated water for irrigation. Constructed wetlands or bed techniques have proven their effectiveness in the treatment of domestic effluents. Their application to cellar effluents, which has been the subject of variousresearch projects for several years, makes it possible to enhance the aesthetic and ecological environment of the cellar. The objective of the communication is to present the principle of purification by a bed planted with reeds with the different possible implementations in the cellars
