Welcome to the blog of Johnathan Grieve.
I am the proprietor of Avondale wine estate, and pioneer of the BioLOGIC® approach to sustainable viticulture.

As Avondale’s vines and fruit trees fall into dormancy at the end of Autumn, we turn our attention to another Biodynamic practice which has multiple benefits. Tree paste, which is also used on vines and bushes is not one of the original practices offered by Rudolph Steiner. Rather it has been developed and used by later, influential proponents such as Maria Thun and is today, incorporated in the farming of many Biodynamic practitioners around the world.read more
The making of liquid homeopathic remedies is essentially to transform a raw material, such as the pepper, into a remedy through a process of dilution and succussion. Succussion is defined as a method to potentise the liquid preparation by shaking it using a specific method.read more
