The Mason family has gone to great lengths to ensure a totally healthy, completely natural product. The Demeter trademark has been used in Australia since 1953 to symbolise quality produce produced using the Biodynamic Agricultural Method. This means much more than simply not applying chemicals. Demeter certification requires a soil structure development. Every aspect of general farm management and soil cultivation ensures the bio-dynamic farm practice produces healthy, living, structured soil. Healthy plants and animals using sustainable agriculture are the result.
