Integrated Production of Wine (IPW): South Africa's Sustainability Certification

The Scheme for the Integrated Production of Wine was formally published on 6 November 1998 under the Liquor Products Act, 1989, formalising a process already well underway in South Africa. A key practical driver of early adoption was the South African fruit export industry. Many South African wine producers also farm apples, pears, and plums for export to the UK, and from the mid-1990s UK supermarkets had insisted on integrated production protocols for these fruit categories. Lessons from that work were directly adopted by the wine industry as it built its own scheme. Technical foundations were developed by the ARC Nietvoorbij Centre for Vine and Wine, whose research team provided the scientific base for the IPW guidelines on integrated pest management, soil and water stewardship, and cellar wastewater management. The 1999 vintage was used as a preparatory year, and the 2000 vintage was the first to be certified. Uptake was immediate and extraordinary: approximately 93 percent of cellars and more than 99 percent of farmers joined in 1998. By the mid-2010s, more than 95 percent of South African growers and cellars were IPW-compliant, a voluntary adoption rate without equal in any other wine-producing country.

IPW certification falls under the jurisdiction of the Wine Certification Authority (WCA), the statutory body appointed by the Minister of Agriculture that also runs the Wine of Origin (WO) scheme. The WCA, renamed from the Wine and Spirit Board on 1 August 2023 under the Liquor Products Amendment Act of 2021, maintains a dedicated IPW office responsible for the day-to-day administration of the scheme. After wide industry consultation, a joint voluntary seal covering both WO and IPW certification became available from the 2010 harvest. To qualify for the joint seal, every link in the supply chain (from the farm through the winery to the bottling plant) must be IPW accredited; the seal cannot be applied if any link in the chain has not been audited. In 2024, 88 percent of all certified wines qualified to carry the joint seal. Compliance is assessed annually through a self-evaluation questionnaire and is independently audited by auditors appointed by the WCA on a random spot-check basis over a three-year cycle. Each producer or cellar can therefore expect to be audited at least once every three years.

IPW is structured around three certifiable components that can be audited separately or in combination. The farm component (viticulture) covers grape production, including pesticide and herbicide use, soil and water stewardship, integrated pest management, alien vegetation control, fynbos and natural habitat conservation, fire management, and biodiversity buffer zones. The winery component (production) covers cellar operations, including wastewater treatment, cooling system refrigerants, packaging materials, recyclable waste streams, energy management, and noise and odour controls. The bottling component covers bottling and packaging activities, including glass and closure sourcing, label materials, secondary packaging waste reduction, and bottling-line water and energy consumption. Key farm-level prohibitions include the use of unregistered agrochemicals, exceeding withholding periods for any agrochemical, and the presence of any non-permitted residue in harvested grapes. Cellars must register all water use with the Department of Water Affairs and Sanitation, and environmental impact assessments are required for the cultivation of virgin soil. The introduction of natural predators in vineyards is encouraged as a core IPM practice, replacing or reducing reliance on chemical interventions.

• Farm (viticulture): grape production, integrated pest management, soil and water stewardship, biodiversity, fire management
• Winery (production): wastewater treatment, refrigerants, packaging, recyclable waste, energy, noise and odour
• Bottling (packaging): glass and closure sourcing, label materials, packaging waste, bottling-line water and energy
• Farm prohibitions: no unregistered agrochemicals; withholding periods must not be exceeded; no non-permitted residues in grapes
• All water use must be registered with the Department of Water Affairs and Sanitation; EIAs required for virgin soil cultivation
• Introduction of natural predators in vineyards encouraged as a core integrated pest management practice

South Africa's Cape wine regions sit within the Cape Floristic Region, one of six recognised floral kingdoms of the world and a UNESCO World Heritage Site inscribed in 2004. The region is home to approximately 9,000 vascular plant species, around 69 percent of which are endemic, and has been identified as one of the world's leading biodiversity hotspots. IPW farm guidelines actively address biodiversity protection: alien invasive plant control (a major issue in fynbos ecosystems), fire management, fynbos and renosterveld vegetation conservation, and the maintenance of natural habitat buffer zones alongside vineyards are all required components of compliance. IPW guidelines reference Critical Biodiversity Areas and Ecological Support Areas identified by CapeNature, the provincial conservation authority, to guide land-use planning on wine estates. The WWF Conservation Champion programme, which was founded in 2004 as the Biodiversity and Wine Initiative (BWI) and was renamed and restructured after 2015 to focus on the industry's environmental leaders, operates alongside IPW as a voluntary additional membership model. To qualify as a WWF Conservation Champion, a producer must achieve at least 70 percent in IPW scoring and adhere to additional biodiversity and regenerative farming principles set by WWF South Africa.

IPW focuses specifically on environmental sustainability; social responsibility in South African wine is addressed by WIETA (the Wine and Agricultural Ethical Trading Association), a separate independent body established in 2002 following a two-year ETI pilot project. WIETA is unique in world wine: South Africa is the only wine-producing country with an independent body focused exclusively on promoting ethical labour and social standards across the wine industry value chain. WIETA audits cover fair wages, safe working conditions, freedom of association, worker empowerment, human rights due diligence, and community engagement. Around 1,000 producers, growers, cellars, and bottling facilities are WIETA-certified, and a WIETA Fair Labour Certification Seal for wine packages was introduced in 2012. South Africa is also the world's largest producer of Fairtrade wine, accounting for approximately two thirds of global Fairtrade wine sales, with 24 producer organisations covering approximately 70 farms and nearly 3,000 workers. IPW guidelines themselves require compliance with all legislation related to the health and safety of workers and the correct handling and disposal of agrochemicals, providing a baseline labour-safety floor even where WIETA certification is not separately pursued.

Sustainable Wine South Africa (SWSA) is the promotional alliance between the WCA, IPW, and Wines of South Africa (WoSA, the country's industry promotional body). SWSA exists to communicate South Africa's certified-sustainable wine credentials to international markets and to coordinate the country's positioning as the global leader in wine sustainability. The combination of IPW's rigorous self-assessment, independent auditing, and supply-chain traceability makes it one of the most verifiable sustainability schemes in the world wine industry. South Africa is described in industry literature as the only country that audits producers so rigorously on sustainability as a prerequisite for a wine seal appearing on the bottle. The scheme complies with internationally recognised frameworks including the FIVS Global Wine Sector Environmental Sustainability Principles and the OIV Guidelines for Sustainable Viti-viniculture, which positions IPW-certified wines for export markets that increasingly require documented environmental credentials. The joint WO and IPW seal on the bottle neck allows consumers and trade buyers to verify origin, variety, vintage, and sustainable production credentials online via sawis.co.za using unique seal numbers, linking back to SAWIS records at pressing. This transparency increasingly resonates with European, North American, and Asian export buyers who require documented sustainability credentials for their listings.
