What's the difference between organic wine, natural wine, and biodynamic wine? The distinctions explained

Biodynamics and natural wine: beyond organic

Biodynamics takes the organic philosophy even further. Inspired by the teachings of Rudolf Steiner in the 1920s, this approach sees the vine as an integral part of a living ecosystem. The Demeter (founded in 1932) and Biodyvin certifications attest to these practices, which follow lunar and solar cycles.

The biodynamic winegrower prepares specific natural decoctions to strengthen the vines. Their mantra: “Prevent rather than cure, protect rather than treat, accompany rather than intervene”. In the cellar, sulphites are even more restricted than in organic winemaking, although fining and filtration are still permitted.

Natural wine, for its part, represents the most minimalist approach. With no official legal framework, it rests on generally accepted principles that nevertheless vary from producer to producer. The absence of additives and the exclusive use of native yeasts characterise this method, which aims to express the terroir in its purest form. If you decide to buy natural wine online, you will discover cuvées that are often surprising and full of life.

The professional association “Vin Méthode Nature” has drawn up a charter that limits sulphites to a maximum of 30 mg/L and requires 100% organically grown grapes. In our experience, these wines often offer unique aromatic profiles that can sometimes unsettle palates used to conventional wines.

What is organic wine and how can you recognise it?

Organic wine is the first step towards more environmentally friendly winegrowing. Since 2012, the European Union has laid down precise specifications governing this designation. These bottles are easy to recognise thanks to official labels such as AB or Ecocert, which guarantee that at least 95% of the ingredients come from organic farming.

Exploring organic estates, we have observed that organic winegrowing practices strictly exclude chemical pesticides and synthetic fertilisers. Mechanical work replaces herbicides, while copper and sulphur become natural allies against vine diseases.

In the cellar, the organic philosophy allows certain interventions while limiting them:

• The addition of sulphites in regulated quantities
• The possible use of commercial yeasts
• Acidification or deacidification of the wine
• The addition of oak chips

To obtain the coveted certification, winegrowers must commit to a conversion period of at least three years. This gives the soil time to regenerate and eliminate chemical residues. Nevertheless, it pays to stay vigilant, as some “organic” wines may hide a less eco-friendly reality than their label suggests.

The key differences between these winegrowing approaches

Between organic and biodynamic, the main distinction lies in the philosophy. While organic focuses mainly on the absence of chemicals, biodynamic winegrowing adds a cosmic and energetic dimension. Our meetings with biodynamic winegrowers have revealed a deep, almost spiritual connection with their terroir.

The difference between organic and natural shows mainly in the cellar. Organic wine follows official specifications but allows certain technical interventions, while natural wine favours maximum non-intervention. Natural wine stands out for its spontaneous fermentations and the near-total absence of added sulphites.

Between biodynamic and natural, the line is subtler. Both approaches aim for an authentic expression of terroir, but by different paths. Biodynamics follows a structured, codified route, whereas the natural approach favours instinct and non-intervention.

Those who care about sustainability will appreciate the regenerative viticulture that is currently transforming vineyards by going even further in restoring ecosystems.

The sulphite factor: a decisive difference between these wines

Sulphites are a major differentiating factor between these approaches. Naturally present in all wines (even without additions), they vary considerably in quantity depending on the production method. In our tasting experience, sulphite levels follow a clear hierarchy, from highest to lowest:

1. Conventional wines (up to 350 mg/L for some sweet whites)
2. Organic wines (limited but present)
3. Biodynamic wines (very limited)
4. Natural wines (minimal or absent)

The question of sulphites goes beyond mere regulation. These compounds protect the wine against oxidation and ensure its microbiological stability. On the other hand, significantly reducing them in natural wines demands particularly precise winemaking and impeccable ageing conditions.

We have found that low-sulphite wines often show more expressive aromatic profiles and a livelier texture on the palate. However, they generally require more careful transport and storage to preserve their qualities.

Ultimately, these different winegrowing approaches respond to a growing demand for more ethical and authentic wines. Each has its merits and challenges, reflecting the constant evolution of our relationship with wine and the environment.
