Soil and root microbiome: discovering the grapevines greatest weapon

Following my recent polemic against the claims of biodynamic winemaking, I spoke with Keith of Mise en abyme who asked me what I’d like to see emerge from the discussion around the legitimacy of biodynamics. My response? A more practical and evidence-based school of thought centred around achieving healthy soils and diverse, resilient ecosystems. Although understudied, it is widely accepted that microbiome is essential in upholding the fabric of life. Our gut, mouth and skin each host their own unique microbiome community whilst healthy soil microbiome is crucial for the growth and longevity of crops and wildlife. Nurturing this symbiotic relationship between this community of bacteria, archaea, viruses, fungi and protozoa is a core tenet of biodynamics. However, a number of studies have shown biodynamic preparations to be ineffective in improving soil health metrics. In this article, I explore microbiome in more detail and discuss working, proven practises for strengthening and diversifying soil microbiome.


The problem with biodynamics: myths, quacks and pseudoscience

Earlier this year, I featured as a panel member for a Real Business of Wine webinar titled ‘Getting the Horn’. Throughout the webinar, the panel explored biodynamics with Monty Waldin, the world’s leading expert on biodynamic wine. Whilst several of my peers did challenge the notion of biodynamics, I was hesitant to do so, feeling the forum was not the most appropriate of places in which to voice my somewhat fierce opposition to Steiner and his quackery. Shortly after the webinar I released an Instagram video briefly summarising my position, admittedly it wasn’t terribly succinct, was a little provocative and did little to convince others as to why they should take a more active position against aspects of biodynamics. Here I hope to lay out my position more clearly, explaining why I so vehemently oppose individuals who profiteer from pseudoscience.
