Established in 1692, Hartenberg Estate should need little introduction, as one of South Africa’s oldest wineries. With a philosophy of combining decades of experience and knowledge of the local terroir and an innovative attitude to how it is cared for. By understanding and working with nature Hartenberg ensure that their wines are unique to their vineyards. Promoting biodiversity and soil health the estate has established a culture of regenerative farming, a system that allows the crafting of wines through environmentally conscious and sustainable methods. The estate has been rated as one of South Africa’s 1st Growth producers by wine critic Tim Atkin MW.

Hartenberg is nestled on the free draining north-eastern slopes of the Bottelary Hills in the Stellenbosch region, where the Mediterranean climate, cool breezes channelled down the valley from the ocean, and poor gravelly soils are great for grape growing. As a leading member of the Biodiversity and Wine Initiative in South Africa, they have established various initiatives to protect the 170 hectares of natural wetland on the farm, ensuring the health of the vines and a sustainable future for the estate.

In January 2025, Hartenberg received Scientific Regenerative Viticulture verification by EOV making it the first wine farm in South Africa – and only the second worldwide – to achieve this certification.  Through innovative regenerative practices, scientific verification and measurable outcomes, Hartenberg not only manages its environmental impact but also provides a powerful example of how regenerative farming methods can transform agriculture, restore ecosystems, and produce exceptional wines, setting a new benchmark for regenerative viticulture. Core regenerative viticulture principles at Hartenberg include cover crops, holistically controlled livestock grazing, minimum-till methods, organic composting, eliminating chemical pesticides and fertilisers, and enhancing biodiversity for a balanced ecosystem.
