The two cornerstones of what is defined as natural wine are maintaining the balance of the vineyard ecosystem and promoting the spontaneous evolution of the wine in the cellar.

To date there is no official certification for natural wine and the interpretation of the terminology often varies.

Generally speaking, any producer that identifies themselves as a natural winemaker follows agricultural practices that exclude the use of synthetic chemicals, as well as the use of additives or invasive processes to correct the colour, aroma and taste of wine in the cellar.
