Dyyna comes from Präparatekiste
The preparation work behind Dyyna began in 1968 on Hof Eichwerder, a farm on Germany’s Baltic coast. Präparatekiste grew out of it, and Dyyna is its international platform.
Our story
1968
Hof Eichwerder converts
Wedig von Bonin converts Hof Eichwerder in Ostholstein to biodynamic farming. He is one of the first Demeter farmers in northern Germany. Over the years, many people learn the preparation work from him on the farm.
1970s
Barrel compost with Maria Thun
Wedig is a close friend of Maria Thun, whose name the biodynamic sowing calendar carries. With her he makes the first trials with barrel compost. It becomes his favourite preparation, and he makes it on Eichwerder for around thirty years.

The first preparations partnership
Wedig von Bonin and Simon Steiner, who grew up on Eichwerder, found a partnership for biodynamic preparations on the farm. In Dornach they present the world’s first online shop for biodynamic preparations.

Präparatekiste
After Wedig’s death, Simon Steiner takes over the preparation work from Eichwerder and builds Präparatekiste into a company of its own. It supplies farms, market gardens, vineyards and home gardens with preparations, equipment and materials for making preparations yourself.
