Welsh winemakers seek legal protection for a natural wine appellation

Welsh wine producers are seeking protected status for what they say could become the world’s first appellation dedicated to natural wine, a move that would create a new legal framework for how such wines are grown, made and described in Britain.

The proposal, called Natural Wine of Wales PGI, has been submitted to the British government and is now under review by the Department for Environment, Food and Rural Affairs, or Defra. According to the application’s backers, the designation would apply only to wines made from grapes grown in Wales and fermented there through spontaneous fermentation, without synthetic chemicals, industrial yeasts, additives or processing aids. Sulfur would be allowed only at bottling and in limited amounts.

The effort is being led by a group of Welsh producers that includes Paul Rolt of Hebron Vineyard in Carmarthenshire, Richard Morris and Jean de Plessis of Ancre Hill Estate in Monmouth, and David Morris of Mountain People Wines. Rolt said the group wants to create standards that define natural wine more clearly and give consumers more information about what is in the bottle.

He said the proposal is also meant to respond to concerns about greenwashing and what he described as ultra-processed wine. In his view, a protected designation with strict production rules would help distinguish wines made with minimal intervention from those marketed with looser claims.

The proposed rules would require vineyards to follow organic practices on estates that are certified organic, regenerative or biodynamic. The application also seeks to include PIWI grape varieties, which are bred for disease resistance and are increasingly discussed in cooler and wetter wine regions as growers adapt to climate pressure.

Rolt said that point is especially important in Wales, where viticulture remains difficult because of geography and rainfall. He said grape growing there is highly site-specific and that producers need flexibility to work with varieties that can deliver more reliable harvests. Consistent yields are hard to achieve in Wales, he said, making climate adaptation central to the future of the sector.

The application was submitted in August 2025. Rolt said he had received positive feedback this year from Defra. A spokesperson for the department said the proposed PGI remains under consideration and that applicants have been asked to provide further information after observations from Defra’s Geographical Indication Scrutiny Panel of Experts.

If approved, the designation would stand apart from current Welsh wine rules. Under the existing Welsh wine PGI, up to 15% of a wine may come from grapes grown in England. Welsh wine can also be produced at wineries across the border. That arrangement has long reflected the practical limits of winemaking infrastructure in Wales, but supporters of the new proposal argue it weakens any claim that such wines fully express Welsh terroir.

Rolt has openly challenged those existing rules. He argues that wines presented as terroir-led should be made in the same country where the grapes are grown. He also says rules that allow Welsh wine to be produced in England have discouraged investment in winery facilities inside Wales.

The proposal arrives at a time when natural wine remains widely used as a commercial term but lacks a single legal definition in Britain. That gap has left room for different interpretations by producers, retailers and consumers. A formal geographical indication tied to production methods and place of origin could therefore have effects beyond Wales, especially if it becomes a reference point for future regulation or marketing standards elsewhere in the British drinks industry.

It could also increase pressure for broader changes in labeling. Rolt said his group wants ingredient information on labels or available through QR codes so consumers can see how wines were made. He said British producers can currently use dozens of products in winemaking without having to disclose them on labels. Unlike producers in the European Union, UK wine producers are not required to list ingredients on bottles.

That issue matters well beyond one category of wine. If regulators or producers move toward fuller disclosure for natural wine, it could influence compliance expectations across the wider beverage business, particularly for companies watching how consumer demands for transparency develop in wine and other alcohol categories.

The Welsh proposal draws partly on existing models abroad. Rolt said it was inspired in part by the Raw Wine Charter and by France’s Vin Méthode Nature label. France introduced that label in 2020 with rules that exclude machine harvesting and allow producers to use one of two bottle logos, including one for wines made with less than 30mg of added sulfur. At the same time, France barred the words “vin nature” from appearing directly on labels.

That French example shows both the appeal and difficulty of trying to regulate a term that has often lived outside formal appellation systems. In Wales, supporters of the PGI are trying to go further by linking natural winemaking not only to cellar practices but also to geography, farming standards and local fermentation.

Ancre Hill Estate, one of the wineries involved in backing the application, is also one of Wales’s largest vineyards, giving the proposal support from a producer with scale as well as visibility. The group behind it says its aim is not simply to create a niche category but to establish a protected identity for Welsh wines made under stricter environmental and production rules.

Whether Defra accepts that argument will help determine if Britain becomes home to a new kind of appellation system, one built around both origin and method. For Welsh producers pushing for recognition, the case rests on two linked claims: that natural wine needs clearer standards, and that Wales should be able to define those standards on its own terms.
