Situated on the cool slopes of Dorstberg with Table Mountain as backdrop, Diemersdal provides the perfect setting for the production of unique, soulful wines.

Diemersdal signed a 10-year biodiversity agreement with Cape Nature to establish a 16.8-hectare conservation area. The vegetation type of the conservation area is Swartland Shale Renosterveld, which is currently the most threatened ecosystem in the country, having lost more than 90% of its original extent. For this reason, Swartland Shale RV is classified as Critically Endangered.

During September 2020 the property was visited, and a basic plant survey was done…During this botanical scan 38 species of flowering plants were recorded. The list is still very preliminary, and it is likely that at least 200 species still occur in this area

The most interesting find was a small population of Endangered Oxalis strigose, as well as Geissorhiza erosa (also Endangered).

At present the veld is extremely old and senescent with most species either dormant or stored as seed in the soil-stored seed banks. Implementing an ecological burn is therefore one of the key management outcomes for the duration of the 10-year biodiversity agreement.

Area conserved: 16.8 ha

Location: Durbanville Valley

Diemersdal Certification & Sustainability

WWF Conservation Champion
Diemersdal Wine Estate has become the latest WWF Conservation Champion. This is a select group of 42 South African wine farms who have met the programme’s stringent requirements, thereby proving themselves to be leaders of nature conservation and sustainable wine production.
Diemersdal signed a 10 year biodiversity agreement with Cape Nature to establish a 16.8 hectare conservation area. This conservation area spans the Dorsberg, the most northern hill range within the Tygerberg cluster, within the city’s bioregional plan, the Biodiversity Network.
• Dryland
All vineyards are unirrigated. Dryland farming is key to Durbanville wine quality resulting in more established, firmer root structure, better fruit character, more varietal expression.
• IPW
Integrated production of wine complies with international wine industry environmental sustainability criteria.
• BRC
A globally recognised GFSI food safety manufacturing programme.
• WIETA
Multi-stakeholder, non-profit, voluntary organisation which actively promotes ethical trade in the wine industry value chain through training, technical assessment and audits to assess members’ compliance with its code of good practice.
• CVC
The Cape Vintner Classification (CVC) is an independent body committed to the accreditation, governance, representation and promotion of distinctive regional site specific Cape wines.
