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.
Ferments are not only used to help solve issues. There are a great variety of beneficial ferments that you can use to promote balanced life on the farm. Many of these are especially effective when you are working to transform depleted land into a fertile, natural farm. Essentially, these ferments serve as tonics. Through the fermentation process we create cultures of microbial life, which through their digestion deliver nutrients the soil needs. Different ferments can be made using plant materials or manures to increase nitrogen or phosphorus or trace elements.read more

As part of our commitment to the Circle of Life, we have recently introduced chickens to Avondale. We have a mix of Rhode Island Reds, Leghorns and Koekoeks, plus 5 Buff Orpingtons – these are all multipurpose chickens being good layers and scavengers who enjoy a wide variety in their diets so in essence great free range breeds.read more
BD508 is a biodynamic preparation also known as Horsetail (Equisetum Arvense) Preparation. It is a ferment or ‘tea’ style preparation that can be applied direct to the soil, plant or atmosphere. Its purpose is to regulate the watery element brought on by too strong or too weak moon forces.read more
