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.
Ambassador card
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

Sven Bruchfeld & Gonzalo Muñoz
Established in 2002 by winemakers Sven Bruchfeld and Gonzalo Muñoz, Polkura focuses on producing high-quality Syrah wines that reflect the unique terroir of the region. The name "Polkura" means "yellow stone" in the Mapuche language, referencing the area's yellow granite soils. These decomposed granite soils, combined with clay, contribute to the wines' minerality, body, and structure.
Situated approximately 30 kilometers from the Pacific Ocean, the vineyard benefits from a Mediterranean climate with significant marine influence, moderated by the coastal mountain range.
Since 2009, Polkura has implemented a dry farming project known as "Secano," cultivating 2 hectares without irrigation, later expanding to 5 hectares. This approach emphasizes minimal intervention, relying solely on natural rainfall to express the purest form of the terroir.
To optimize water retention, vines are planted on flat terrain with clay-rich soils and at a lower density of 2,500 plants per hectare. The Gobelet training system is employed, with shoots tied to individual stakes to protect the fragile Syrah vines from breakage.
