A wine resulting from biological vine growing is a wine produced starting from grape resulting from the biological vine growing. These wines are guaranteed by a certification delivered by organizations, such Écocert or Demeter in France, represented by the logo AB.

To obtain this label, the vines must be led according to a precise schedule of conditions: prohibition of the chemical weed control and the use of pesticide of synthesis. The protection of the vineyard is done only with chemicals of natural origin such suffers it (against the Oïdium) and it copper sulfate (against the Mildiou). Certification is limited to the grape and does not enter counts some in the process of Vinification. A wine bio guarantees the method of vine growing, but not the talent of the vine grower or the quality of the wine making.

Of ten at the beginning the Years 1980, the wine growers bio are, in France in 2005, 1.500.

Another reason, more commercial, is that there exists today a true market of agricultural produce bio.

Moreover, much of other farmers, even if they did not pass the course of the biological vine growing, work in the framework and the principles of a reasoned Agriculture with an aim of reducing their consumption of plant health products and manure. But let us specify well that the organic farming and agriculture " raisonnée" nothing has philosophically jointly.
