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.

Natural Fermentation Creates A Slow Holistic Evolution

Natural Fermentation Creates A Slow Holistic Evolution

Avondale is farmed organically and biodynamically. No chemicals are used in the vineyards or in the cellar, nor are chemicals added to the grapes when they arrive at the cellar. All our fermentations are spontaneous and natural caused by the unique yeasts present on the grapes.

Beauveria Bassiana – Broadspectrum to be used with focus control

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.

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.

Beneficials to beat Bollworms

Beneficials to beat Bollworms

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.

As family man… Avondale is a family farm where we appreciate that the health and balance of our living system is inextricably linked to well-being of our families. As a father of two and a husband, as son and brother, my inspiration to achieve a robust, balanced vineyard ecosystem is to ensure that Avondale will support the lives of our future generations.

As artist… A passion for jazz and a love for all forms of art, especially woodwork and sculpture led me into four years of fine art studies – an eclectic education for a budding a farmer, for sure! However, I have found that in so many ways, the patterns, interconnections and openness of the artistic worldview have influenced my understanding of how living systems work.

As farmer… My interest in farming started early when I was a boy growing up on a small-holding outside of Durbanville. I planted and tended my own vegetables which I sold to family and friends. I hardly imagined at that time though that I would one day become a farmer. However, the theme of a healthy balanced life was embedded in our family’s outlook.
