Organic wine is wine made from grapes grown in accordance with principles of organic farming, which typically excludes the use of artificial chemical fertilisers, pesticides, fungicides and herbicides.
Natural wine is wine made with minimal chemical and technological intervention, both in growing grapes and making them into wine. The term is used to distinguish such wine from organic wine and biodynamic wine because of differences in cellar practices.
Biodynamic wines are wines made employing biodynamic methods both to grow the fruit and during the post-harvest processing. Biodynamic wine production uses organic farming methods (e.g. employing compost as fertiliser and avoiding most pesticides). For a wine to be labeled “biodynamic” it has to meet standards laid down by the Demeter Association, an internationally recognised certifying body.
