Biodynamic wines are both Organic and adhere to the regulations set out by the Demeter Association, who govern and certify, as of 2017, 603 wineries worldwide, covering 19 countries and 13,158 hectares of Vineyards.
 

Certification extend to both the viticulture (growing the grapes) and the viniculture (making the wine)
 

Key differences to organic wine.
 

When treating the vines and the soil the compost must be biodynamically produced as must any field sprays to combat, mildew, insects or disease.
 

The Vineyard as part of an Ecosystem is central to the Biodynamic culture. The grape crop growing cycle follows a timetable that is determined by astrological influences and the lunar cycle.
 

Only naturals yeasts are permitted to ferment the wine. Acidity adjustments are not permitted in the wine making process.
 

So, it is possible to have a wine made “using biodynamic grapes”, but it would only be Biodynamic if the Grapes were both farmed biodynamically and the Vintner followed the stricter Biodynamic rules such as Sulphite use, natural yeast and the control of acidity.
