Made with organically grown grapes means the wine must be made entirely from certified organic grapes. Additional ingredients used in the winemaking process need not be organic, but they cannot be produced with the use of pesticides or synthetic fertilizers. Biodynamics represent a method of farming based around a specific astronomic calendar. Each day coincides with one of the elements: earth, fire, air and water. Days are organized by fruit days (preferable for grape harvesting), root days (pruning), leaf days (watering) and flower days, where the vineyard should be untouched.
