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.
Veganism is on the increase. In 2018 Forbes reported that between 2014 and 2017 the US experienced a 600% increase in people identifying as vegan. A vegan is someone who avoids products, particularly food and drink, that consist of animal products.
While hosting a recent tasting a discerning taster asked me, whether our “wines contain Sulphur?”. As tasters become more knowledgeable and health-conscious, questions like these are becoming more common. This is an important topic and I’d like to take some time to explain the Avondale approach to managing Sulphur. Read more.

“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...
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.
Nutrient density simply means the level of nutrients in our food sources. At Avondale we take a particular interest in the nutrient density of the plants and soils as they are the fundamental building blocks of the food we serve and the wines we make.
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.
