Holle was founded in 1933 and uses milk from cows raised on biodynamic Demeter farms. The thing that makes Holle most unique is that it uses milk from cows raised on biodynamic (Demeter) farms in caring and natural environments. Healthy cows that can graze on lush fields and pastures - free of pesticides or chemical fertilizers - is the reason for the high quality of the milk produced. Demeter farmers also avoid the painful dehorning of cows.
