The Graaff family have a deep respect for nature and the environment. 

The Graaff family motto is Justis Favet Creator (The Creator favours Justice). It is a motto that each generation strives to live up to, especially when it comes to the natural environment.


De Grendel is a proud member of the WWF's Biodiversity and Wine Initiative (BWI),  a pioneering partnership between the country’s wine industry and conservation sector, it protects the natural habitat, encourages wine producers to farm sustainably and to express the advantages of the Cape’s abundant diversity in their wines. Over 140 000 hectares of natural area have been conserved by BWI producers since project inception.

The farm is situated within a pristine natural vegetation area known as 'Renosterveld' and the conservation thereof is a passion of the family. Home to rare and endangered floral species, this delicate ecosystem has been preserved for future generations. The diversity of the farming activities on De Grendel further enhances their philosophy of sustainable agricultural practices to support their long-term vision for the Graaff family legacy in the landscape.

Proudly carbon-negative

De Grendel is proudly carbon negative. An assessment of greenhouse gasses emitted and absorbed through operations on the De Grendel wine and dairy estate established that the Durbanville farm is a net carbon sink, meaning that the farm releases less carbon into the air than it absorbs through growth of vegetation on the farm.

Solar Energy

Investing in solar photovoltaic energy has proved a wise decision for De Grendel, both financially and environmentally, and enhanced the Graaff family’s deep legacy of sustainable stewardship of the historic farm.

The solar photovoltaic (PV) plant commissioned at the end of 2015 consistently exceeds its targeted output and now powers a third of De Grendel’s operation, resulting not only in cost savings but also further improvement in De Grendel’s sustainability and already negative carbon footprint.

A terraced indigenous garden cascades towards the cellar. Using water-wise principles, a series of agricultural drains capture storm water through the wet season and send it down to the dam where it is circulated.

Plant wise, De Grendel took its lead from the fynbos found on the Tygerberg, using Buchu plants, Restios, Proteas and Pincushions. Wild grape covers the pergola leading to the front entrance of the cellar complex.
