Welcome to the blog of Johnathan Grieve.
I am the proprietor of Avondale wine estate, and pioneer of the BioLOGIC® approach to sustainable viticulture. The transformation of Avondale from over-used and abused land into a thriving, robust vineyard ecosystem has been a personal learning journey of more than a decade long. This blog is where I share some of what I have learnt about promoting life on our farm and the wonderful impact this has had on our handcrafted premium quality wines.
“Save Water; Drink Wine” they said. But what they didn’t say is how much water is used to make a bottle of wine. The industry average is 6 liters of water; but luckily here at Avondale this has been brought down to 2.5-3 liters of water per bottle of wine. This...read more
Beauveria Bassiana is a broad spectrum fungi which is most often found growing in soils. This fungus is utilised as a biological pest control measure specifically targeting insect pests, such as red spider mites, termites, aphids, thrips and ants. At Avondale we use Beauveria Bassiana to control our ant populations in a very focused manor.read more
The drought has major effects on faming on all fronts and Avondale is no exception to this.
However through foresight and respect for our natural resources we are currently having minimal detrimental consequences.
With our commitment to organic and Biodynamic farming, and to preserve our healthy vineyard ecosystem, we’ve turned to biological controls in order to avoid fungicides. Nature provides alternatives in the form of various strains of beneficial bacteria, such as Bacillus amyloliquifaciens and Bacillus subtilis, which are highly effective at preventing common, threatening fungal infections.read more

In this third article in our series about using beneficials to solve challenges naturally and avoid harmful chemicals in the farm environment, we look at solutions for a common problem – bollworms. A bollworm is not a worm, but the larvae (caterpillars) of a number of different moth species. Voracious eaters, they do give farmers a real hard time.read more
We started this series of articles on the role of ‘beneficials’ in natural farming with an overview that highlighted how everything from bats to bacteria can help you to maintain a healthy farm ecosystem. Beneficials play a vital role in helping you to avoid the use...read more
