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.​

Isabella Hof

Isabella Hof is a pioneering organic onion farmer in the Netherlands, taking over the farm from her father, who paved a path at a time when the market for organic was lacking.

Now, they have two businesses: their farm and an onion-sorting company. The main crops on their 200-hectare farm include onions, seed onions and flax, and they also grow wheat, barley, sugar beets, potatoes and grass seeds. The onions they grow and purchase are exported and sold to consumers through retail outlets in the Netherlands.

Due to the pressure of chemicals on the soil and climate, they have seen yields decline and weeds, diseases and pests increase for years, both on their farm and those of their growers. Because of these concerns, Isabella started taking courses at De Oorsprong and Agrosymbio and has begun experimenting with regenerative practices. Isabella is passionate about building healthier soil, products and business, and involving their growers along the way.
