Bio
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.

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 .
