Bio
Joost de Willebois is the founder and owner of Domaine J. de Villebois, a family-run winery in France's Loire Valley.
Originally from the Netherlands, Joost descends from a French lineage dating back to 1180. In 2004, he and his wife, Miguela, acquired a 10-hectare vineyard in Mareuil-sur-Cher, marking the beginning of their winemaking journey.
They focused on producing Sauvignon Blanc, aiming to become specialists in this varietal within the Loire region. Over the years, the domaine expanded its reach across key appellations like Sancerre, Pouilly-Fumé, and Menetou-Salon.
Joost transitioned from a career in finance to dedicate himself fully to winemaking, emphasizing sustainable practices. Today, Domaine J. de Villebois is recognized for its high-quality Sauvignon Blancs and commitment to environmental management.

The soil microbiome plays a critical role in optimizing crop yields, nutrition, and stress resilience. To assess the impact of StimBlue+ on the microbial pathways essential for wine grape development, we partnered with Biome Makers, a leader in assessing soil health at scale. Through their rigorous analysis, we examined the influence of StimBlue+ on soil microorganisms and their functions, providing incredible insights into how our product enhances soil health and vine performance. The tests were done on the vineyards of Domaine J. de Villebois.
Testimonial from BiomeMakers:
"With StimBlue+, we saw a unique boost in nutrient availability. Even through foliar application, BeCrop analysis confirmed these effects across fields, highlighting the reach and effectiveness of this biostimulant" Juan Rebori, BiomeMakers

Michael Kavanagh
Thompson Farm, managed by Michael Kavanagh, is a leading example of regenerative agriculture in the UK.
Situated at Church Farm in Boningale, near Wolverhampton, this 688-hectare estate is part of the Green Farm Collective—a network of British farmers dedicated to sustainable and nature-enhancing practices.
Under Kavanagh's stewardship, Thompson Farm has transitioned from conventional methods to a regenerative model focusing on soil health, biodiversity, and reduced chemical inputs. Key practices include:
Minimal Tillage: Adoption of direct drilling techniques has improved soil structure and reduced fuel consumption.
Cover Cropping: Utilization of diverse cover crop mixtures to enhance soil fertility and provide forage for livestock.
Biological Inputs: Application of composts and liquid seaweed extracts to support microbial activity and plant health.
These strategies have led to an increase in soil organic matter from below 2.5% to 3.25% over six years, enhancing water retention and resilience against drought.
As a founding member of the Green Farm Collective, Thompson Farm collaborates with other like-minded farmers to promote regenerative agriculture. The collective facilitates knowledge sharing, supports natural capital trading, and engages with businesses seeking to invest in sustainable farming practices .
